A display of brand loyalty

12th July 2013

Since 2007, my main camera has been a Pentax K10D DSLR and it has gone on many journeys with me. In fact, more than 15,000 images have been captured with it and I have classed it as an unfailing servant. The autofocus may not be the fastest but my subjects tend to be stationary: landscapes, architecture, flora and transport. Even any bus and train photos have included parked vehicles rather than moving ones so there never have been issues. The hint of underexposure in any photos always can be sorted because DNG files are what I create, with all the raw capture information that is possible to retain. In fact, it has been hard to justify buying another SLR because the K10D has done so well for me.

In recent months, I have looking at processed photos and asking myself if time has moved along for what is not far from being a six year old camera. At various times, I have been looking at higher members of the Pentax while wondering if an upgrade would be a good idea. First, there was the K7 and then the K5 before the K5 II got launched. Even though its predecessor is still to be found on sale, it was the newer model that became my choice.

Pentax K5-II

My move to Pentax in 2007 was a case of brand disloyalty since I had been a Canon user from when I acquired my first SLR, an EOS 300. Even now, I still have a Powershot G11 that finds itself slipped into a pocket on many a time. Nevertheless, I find that Canon images feel a little washed out prior to post processing and that hasn’t been the case with the K10D. In fact, I have been hearing good things about Nikon cameras delivering punchy results so one of them would be a contender were it not for how well the Pentax performed.

So, what has my new K5 II body gained me that I didn’t have before? For one thing, the autofocus is a major improvement on that in the K10D. It may not stop me persevering with manual focusing for most of the time but there are occasions the option of solid autofocus is good to have. Other advances include a 16.3 megapixel sensor with a much larger ISO range. The advances in sensor technology since when the K10D appeared may give me better quality photos and noise is something that my eyes may have begun to detect in K10D photos even at my usual ISO of 400.

There have been innovations that I don’t need too. Live View is something that I use heavily with the Powershot G11 because it has such a pitiful optical viewfinder. The K5 II has a very bright and sharp one so that function lays dormant, especially when I witnessed dodgy autofocus performance with it in use; manual focusing should be OK, I reckon. By default too, the screen stays on all the time and that’s a nuisance for an optical viewfinder user like me so I looked through the manual and the menus to switch off the thing. My brief flirtation with the image level display met an end for much the same reason though it’s good that it’s there. There is some horizon auto-correction available as a feature and this is left on to see what it offers since there have been a multitude of times when I needed to sort out crooked horizons caused by my handholding the camera.

The K5 II may have a 3″ screen on its back but it has done nothing to increase the size of the camera. If anything, it is smaller that the K10D and that usefully means that I am not on the lookout for a new camera holster. Not having a bigger body also means there is little change in how the much camera feels in the hand compared with the older one.

In many ways, the K5 II works very like the K10D once I took control over settings that didn’t suit me. Both have Shake Reduction in their camera bodies though the setting has been moved into the settings menu in the new camera when the older one had a separate switch on its body. Since I’d be inclined to leave it on all the time and prefer not to have it knocked off accidentally, this is not an issue.  Otherwise, many of the various switches are in the same places so it’s not that hard to find my way around them.

That’s not to say that there aren’t other changes like the addition of a lock to the mode dial but I have used Canon EOS camera bodies with that feature so I do not consider it a step backwards. The exposure compensation button has been moved to the top of the camera where I found it very easily and have been using perhaps more than on the K10D; it’s also something that I use on the G11 so the experimentation is being brought across to the K5 II now as well. Beside it, there’s a new ISO button so further experimentation can be attempted with that to see how it does.

If I have any criticism, it’s about the clutter of the menus on the K5 II. The long lists through you scrolled on the K10D have been replaced with a series of extra tabs so that on-screen scrolling is not needed as before. However, I reckon that this breaks up things too much and makes working through the settings look more foreboding to anyone who is not so technical in mindset. Nevertheless, settings such as the the type of file to capture are there and I continue to use RAW DNG files as is usual for me though JPEG and Pentax’s own RAW format also are there. For a while, I forgot to set the date, soon found out what I did and the situation was remedied. The same sort of thing applied to storing files in different folders according to the capture date. For my own reasons, I turned this off to put everything into a single PENTX directory to suit my own workflow. My latest discovery among the menus was the ability to add photographer and copyright holder information to the EXIF metadata attached to the image files created by the camera. With legislative proposals that dilute the automatic rights of copyright holders going through the U.K. parliament, this seems a very timely inclusion even if most would prefer that there was no change to copyright law.

Of course, the worth of any camera is in the images that it produces and I have been happy with what I have been getting so far. The bigger files mean less images fit on a memory card as before. Thankfully, SDHC card capacities have grown even if I don’t wish to machine gun my photography altogether. While out and about, I was surprised to apertures like F/14 and F/18 when I was more accustomed to a progression like F/11, F/13, F/16, F/19, F/22, etc. Most of those older values still are there though so there hasn’t been a complete break with convention. The same comment applies to shutter speeds where ones like 1/100 and 1/160 made there appearance where I might have expected just ones like 1/90, 1/125, 1/250 and so on. The extra possibilities, and that is what they are, do allow more flexibility I suppose and may even make it easier to make correct exposures though any judgement of correctness has to be in the eye of a photographer and not what a computer algorithm in a camera determines. For much of the time until now, I have stuck with an ISO of 400 apart from a little testing in a woodland area of an evening soon after the camera arrived.

Since the K5 II came my way a few months ago, I have been meaning to collect my thoughts on here and there has been a delay while I brought mu thinking to a sensible close.At one point, it felt like there was so much to say that the piece became larger in my mind that even what you have been reading now. After all, there are other things that I can adjust to see how the resulting images look and white balance is but one of these.The K10D isn’t beyond experimentation either, especially since I discovered that shake reduction was switched off and it has me asking if that lacking in quality that I mentioned earlier has another explanation. Of course, actually making use of my tripod would be another good suggestion so it’s safe to say that yet more photographic explorations await.

A new acquisition

16th January 2010

Back in the early days of this blog, I mulled over the idea of having a high-end digital compact camera to complement a DSLR that then was delivering very dusty images; that Canon EOS 10D was cleaned since then and comes in for occasional use to this day. That was nearly three years ago and a first generation Ricoh GR Digital was the item that then was catching my eye. At the time, I failed to justify spending that much money on such a thing and ended up acquiring a new Pentax K10D DSLR instead. The question that rattled about my head was this: what was the point of spending DSLR money on a compact camera? Its one that never really went away and comes to mind when you see the prices of interchangeable lens compacts like Olympus’ Pen and equivalent offerings from Panasonic and Ricoh (there, it’s interchangeable lens units rather than actual lenses).

The strongest counterpoint to the cost conundrum is the little matter of size. SLR (film or digital) cameras are sizeable things and there is a place for having something that drops into a pocket. It is that which has propelled me into taking delivery of a Canon PowerShot G11. It may need a good-sized pocket but, unless you are going out with no jacket, it shouldn’t be a problem most of the time. For those shorter sorties when I don’t fancy bringing an SLR out, it well-built and looks the business though some acclimatisation is in order to make the best of the knobs, buttons and menus. Nevertheless, the included manual will help with this process (there’s a paper quick start guide and more detailed documentation on CD).

Canon PowerShot G11

The camera hasn’t seen extensive use just yet so here are a few early impressions. Firstly, there’s the matter of size: it’s even smaller than the first camera that I ever bought (more than fifteen years ago) and that was a Ricoh 35 mm compact film camera. That comparison is even more striking when you consider the feature sets. The Ricoh was a fixed 35 mm lens affair with things like date and time stamping, ISO choice and a nod towards scenic mode selection. In contrast, the much newer Canon is loaded with the sorts of things that normally are found almost exclusively on SLR’s, starting with its effective 28-140 mm focal length range.

Exposure modes such as manual, aperture priority and shutter priority complement scene-based modes and another for movies (not a concern of mine, it has to be said). As if that weren’t enough, there’s exposure compensation too. It came as a surprise to me to find a form of manual focussing included though it is not as convenient as turning a focussing ring on a lens. You can see the inbuilt flash above but there’s also a hotshoe and a place to attach a tripod too. Settings like white balance and file format are accessed using the Function/Set button with the lever underneath the shutter release button controlling the focal length of the lens. In addition, there’s also image stabilisation and that’s important when you’re using live view to compose a photo. Spot metering and focal point selection are other things that find their way into the package. Some may be excited by other things but exposure and focussing are essential for any photographic efforts.

An optical viewfinder is included and it has dioptre settings too but my first impressions are that live view though the rear screen trumps it and I see no need for such things on SLR’s. That also flips out from the camera body and can be rotated either for self-portraiture or for folding back in on the camera body for use like a non-articulated screen. Another use is with those occasions when the subject means holding the camera in positions that would be impossible with a conventional screen; holding the camera over your head or down low on the ground are the sorts of situations that come to mind.

Of course, there’s more there than those features that I have listed and the specifications on the Canon website are as good a place to start as any. So far, my only testing has been of the cursory checks variety and to make sure that the thing works properly. Still, this has given me more of a feel for the camera and how it operates. As you’d expect, high ISO settings are noisy but a bigger surprise was that the smallest aperture setting is f/8. Being used to SLR’s, I was expecting to get f/16 and its like on there but a spot of internet investigation showed that I should have been taking the size of the sensor into account with my expectations. Any trials so far have been in dull weather so I’d need to use it in a wider variety of conditions before giving it the sort of wider appraisal that you’d find in the likes Outdoor Photography (who liked it, it has to be said). For what it’s worth, I have found no major criticism so far though I cannot see it usurping my SLR’s but that never was the intention anyway.

8?

12th October 2009

It now seems that we have a new version of Photoshop Elements from Adobe for every year unless you’re a Mac user. Version 7 convinced me to splash out and that gained me Camera Raw recognition of my Pentax K10D along with subtly enhanced image processing power that I have been putting to good use to get more pleasing results than I ever got before. What can be achieved by using levels, curves and the shadow/highlight adjustment tool for exposure correction has amazed me recently. Quick selection functionality has allowed me to treat skies differently from everything else in landscape photos, a flexible graduated filter if you like. It seems to work on Windows 7 along with Vista and XP so I plan to stick with it for a while yet. As you may have gathered from this, it would take some convincing to make me upgrade and, for me, version 8 doesn’t reach that mark. All in all, it seems that it is a way of giving Mac users a new release with added goodness after having to stay with 6 for so long; yes, there are new features like autotagging in the image organiser but they just don’t grab me. Given that they already have Aperture from Apple and Windows users seem to get more releases, it’s a wonder that any Mac user would toy with Elements anyway. Maybe, that’s Adobe’s suspicion too.

Taking a camera on a walk…

24th July 2007

On Saturday, I happened to be in Jessops and overheard a salesman emphatically state that you don’t buy a camera for its specifications but for the photos that it produces. While his tone of voice was a touch condescending and he seemed to be putting down a DSLR, he was essentially right. Nevertheless, the specifications do help you get the images and they have to be seen in that light. For instance, having on-board sensor cleaning may save you from having either to clean the thing yourself or send the camera away for the professionals to do the needful, a much safer option in my view. And there may be occasions where image stabilisation is very useful, low light wildlife photography for instance. Yes, there are features that I consider surplus to requirements, like live viewing and movie capture and that is very much due to my buying cameras to make photos. The salesman in question would surely have agreed…

Sunday saw me head to the Lakeland Fells for some walking and a spot of testing of my new Pentax K10D. The details of the walk itself are not for here but for my hillwalking blog and that is where you will find them. While making my way from Crewe to Windermere, I perused the manual looking particularly for information pertaining to functions that I actually use, I should really have done this beforehand, but distractions meant that I hadn’t got around to it. I had to wade through something designed for a new SLR user before I got to what I consider the important stuff. Though this may be a bit irritating, I can understand and accept why they do it this way; we were all new users once and they are hardly likely to want to know about things like aperture priority, raw file capture, ISO control and such like straight away.

What do I think of it then? Let’s start with first impressions. It is definitely smaller than the Canon EOS 10D it accompanies in my possession. That said, it is not too small and there is a decent grip hosting the shutter release button and the camera on/off switch. It also feels well-assembled and reassuringly weighty, an important consideration given that it will see the outdoors a lot. A discussion of the features most relevant to me follows.

On the subject of switching on and off, the camera is set to go into a sleep mode after a second of inactivity but it reawakens quickly when needed, the trigger being half-depression of the shutter release button. In fact, the camera does reawaken much faster than my Canon as it happens and where the delay is a constant source of some irritation. It might sound strange but the on/off switch is also used to activate the depth of field preview, something that no SLR should not have. The location may be unusual, but maybe the designers thought that having shutter release and depth of field preview next to each was a logical way to do it. From a camera operation point of view, there is certainly something to that way of thinking. Behind the shutter release, you’ll find a screen that is a reminder of film SLR’s and it conveys information such as battery life, number of exposures remaining on the card and exposure details (aperture & shutter speed).

Staying on the subject of screens, the one on the back of the camera is larger than that on the Canon. As is customary for these, it allows replay of photos taken and access to the various menus required to control the camera’s operation. In comparison to the Canon, which is essentially a one menu affair with a thumb wheel controlling scrolling and an OK button at its centre to perform operations, the Pentax has a more elaborate system of submenus: one each for recording, playback and set-up. The playback menu is where I found the setting that makes the camera highlight areas of underexposure and overexposure during image playback. This is something that I missed with respect to the Canon until I happened upon it. Camera cleaning is located on the set-up menu and the camera is now set to clean the sensor every time that it is turned on. Why this is not enabled by default is a little beyond me, but the designers might have thought that a vibration from the camera on turning it on could have resulted in a load of support calls. The same submenu also hosts memory card formatting. The recording submenu is where I set the camera to deliver RAW DNG files, an Adobe innovation, rather than the default JPEG’s. There are other options like RAW PEF files, Pentax’s own format, or RAW and JPEG simultaneously, but my choice reflects my workflow in Photoshop Elements; I have yet to stop the said software editing the DNG files, however. With all these options, it is fortunate that there is a navigation wheel whose operation uses arrow buttons to get about. While on the subject of the back screen, there are further settings that are accessed with the FN button rather than the Menu one. These include ISO, white balance, shooting mode (single, continuous, timed and so on) and flash. The only setting that I changed out of this lot was to set the ISO to 400; I prefer to feel that I am in control.

Returning to the camera’s top plate, the exposure mode dial is on the left-hand side, which is no hardship to me as this is in the same place as on the Canon. There are no scene modes, but the available exposure modes are more than sufficient: fully automatic, program, sensitivity priority, shutter priority, aperture priority, shutter and aperture priority, manual, bulb and external flash synchronisation. A few of these need a spot of explaining. Sensitivity priority is no one on me but it is a consequence of the ability of DSLR’s to offer a range of ISO settings; the aperture and the shutter speed are varied according to the ISO setting. Shutter and aperture priority is like manual exposure and is the inverse of sensitivity priority: set both aperture and shutter speed, and the camera will vary the ISO setting. Both of the foregoing assume that you let the camera set the ISO but my setting the thing myself may have put paid to these functions. Shutter priority and aperture priority are, as far as I can tell, their usual selves. For all exposure modes, the thumb wheels at the front and back of the shutter release handgrip set apertures and shutter speeds where appropriate and this arrangement works well.

Mounting on the same column as the exposure dial the metering mode selector and here is where I see more options than my Canon, which has only full and partial multi-segment metering. With the Pentax, you get spot and centre-weighted metering in addition to the default multisegmented variety. Spot metering is definitely very useful but capturing the reading is a multitasking affair: half pressing the shutter button and fulling pressing the AE lock one at the same time. In contrast, Canon’s partial metering is a more convenient single button operation meter and retain facility. Pentax would do well to learn from this.

The focussing mode selector is found on the left of the body next to the lens coupling. I am used to having this on the lenses themselves, so this is a new arrangement for me and one to which I can easily become accustomed. In fact, it is easy to find it while composing a picture. The modes themselves are manual focus, one-time autofocus and continuous autofocus; the last of these is for focussing on moving objects.

I could go further, perhaps overboard, with a discussion of the features of this camera but I draw a line at what’s here. Yes, it is useful to set the focussing point and activate image stabilisation but the above are what matter to me and its performance in the photo making department is the most important aspect. That neatly brings me to my appraisal of how it performs. With inspection of the first few images on the review screen, I was a little disappointed to see how dark the foreground was in comparison to the sky. When I brought everything home as I always do, I found that things weren’t necessarily as they appeared in the field. The Pentax more usefully offers histogram review and highlighting of any areas that are either underexposed or overexposed. It is these functions that I will be using in reshooting decisions while out and about with the Pentax and the same can be said for how I currently use the Canon. In fast changing lighting, the AE lock technique was a bit irritating but I am certain that I will get better at it. The autofocus doesn’t always lock onto the subject, especially in tricky lighting, so manual focussing is a definite necessity and is more useful more for landscape photography, in fact. Nevertheless, the autofocus did do well most of the time and my Sigma lenses have done worse things on me. All in all, I am happy with the K10D and will continue to use it. I have got some decent photos from my excursion and that, as that Jessops salesman would agree, is the main point of a camera.

Ricoh Caplio GX100?

14th June 2007

Ricoh Caplio GX100

Because my digital SLR has needed to be sent away for cleaning for a while now (in the meantime I have got good at using Photoshop Elements to clean up up pictures…), I have been on the lookout for a backup camera so that I can add photos to any trip reports on my hillwalking blog without having to wait for film to be processed. Previously, my eye was on Ricoh’s GR Digital but they have now introduced the award-winning Caplio GX100. The zoom range is a very useful 24-72 mm in 35 mm film terms and that removable electronic viewfinder looks very neat. Having a 10 megapixel sensor adds to the appeal and advanced exposure modes like manual and aperture priority. The feature list has almost ensured its ousting of the GR Digital from any wish list that I might have; the only thing outstanding is seeing how it performs in a photography magazine’s full test review. A thumbs up from there might even get me onto the acquisition trail…
