TOPIC: CANON POWERSHOT G
A Look at a Compact System Camera
4th September 2013In August, I acquired an Olympus Pen E-PL5, and I'm still getting used to it. Its main appeal was combining SLR functionality with compact camera size. This was an upgrade from my Canon PowerShot G11 without the bulk of a larger camera.
When I considered Canon's EOS M before choosing the E-PL5, I was put off by its slow autofocus. The lack of a mode dial was another concern, though its APS-C sensor and price of around £399 were attractive (and I liked Canon's tendency to overexpose when examining images from an old Canon EOS 10D). After seeing a camera comparison in Practical Photography, I bought that issue. They preferred the similarly priced Olympus Pen E-PM2 over the Canon. Though a Panasonic won the test, I was interested enough in the Olympus to research further. Unlike the E-PM2 and EOS M, the E-PL5 has both a mode dial and extra grip, so I chose it despite the higher price. I had noticed discounted Olympus Pen models before, but this purchase was a more deliberate investment.
Breaking my usual preference for black cameras for variety's sake, I chose the silver E-PL5 from the three available colours (black, silver and white). The body is very compact, with the lens taking up most of the bulk. The standard 14-42 mm zoom means this isn't a shirt-pocket camera, so I bought a black Lowepro Apex 100 AW case. The case fits the camera snugly, making me wonder if I should have chosen a larger one, but it's working well. To protect the lens during outings, I also added a 37 mm Hoya HMC UV filter. The lens's plastic construction extends further than I expected and doesn't fully retract into its housing like some of my Sigma lenses.
On my first test run, I needed to work out how to hold the camera. My Canon PowerShot G11's powered zoom and autofocus made it more intuitive to hold, as was true for any SLR I've used. Holding the small body while adjusting the zoom lens was awkward at first. Eventually, I learned to steady the body with my right thumb (the curved thumb grip on the back holds a thumb vertically) while freely adjusting the lens with my left hand. An electronic viewfinder instead of the screen would have made things easier, but they're expensive, and I had already spent enough.
After learning to hold the camera, I needed to adjust to its exposure characteristics. From my experience, it tends to overexpose. Though I set it to store raw (ORF) files that can be fixed later, I prefer more control during capture. Also, I haven't found a spot or partial metering button like those on my SLR or G11. This means either using exposure compensation with aperture priority mode or switching to fully manual exposure. Other familiar modes are available (shutter priority, program, automatic, etc.). While getting familiar with the camera, I'm using bracketing after setting ISO to 400, increasing screen brightness and adding histograms to playback views. As my grip becomes more secure, I'm using the dial to adjust settings like aperture (f/16 remains my favourite despite what others think about micro four thirds sensor size) and compensation, keeping scenes consistent to test the camera's response to changes.
Though I'm still learning, I'm seeing pleasing results that encourage me to continue; some remind me of my Pentax K10D. The E-PL5 is slower to use than the G11, but that's often beneficial for photography. Being forced to slow down in our hectic world is another advantage. The G11 is seeing less use now, with sunny days offering chances for more experimentation and familiarisation. My introduction to compact system cameras has shown they're very different from compact fixed lens cameras or SLRs. Neither type is truly replaced; instead, a new category has emerged.
A display of brand loyalty
12th July 2013Since 2007, I've used a Pentax K10D DSLR as my main camera. It has travelled with me extensively, capturing over 15,000 images and serving reliably. Though its autofocus isn't the fastest, this doesn't matter for my typical subjects: landscapes, architecture, flora and transport (stationary buses and trains, for instance). Any slight underexposure in photos can be easily fixed since I shoot in DNG format, which preserves all raw image data. The camera has performed so well that I've found it difficult to justify buying a new SLR.
Lately, I have been 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.
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 before 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.
Some features will not get used, though. While I rely on Live View with my PowerShot G11 due to its poor optical viewfinder, I rarely use it on the K5 II with its bright, sharp viewfinder, especially after noticing unreliable autofocus when using it (though manual focusing should work fine). By default, the screen stays on constantly, which irritated me as an optical viewfinder user, so I consulted the manual to turn it off. Similarly, I quickly abandoned the image level display. However, I've kept the horizon autocorrection feature enabled, as it helps fix the crooked horizons that often result from handheld shooting.
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 than 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 difficult to find my way around them.
The K5 II includes other changes, like a mode dial lock, but I'm familiar with this feature from Canon EOS cameras, so it doesn't feel like a downgrade. The exposure compensation button has been relocated to the top of the camera, making it easier to find and use; I'm using it more than I did on the K10D. Since I also use this feature on my G11, I'm applying similar experimentation to the K5 II. Next to it is a new ISO button, which I plan to test to see how it performs.
My main criticism of the K5 II is its cluttered menu system. The K10D's long scrollable lists have been replaced with multiple tabs that eliminate on-screen scrolling. However, I think this fragments the interface too much and makes navigating settings more intimidating for less technical users. Essential settings remain accessible; I continue using RAW DNG files as usual, though JPEG and Pentax's proprietary RAW format are also available. After initially forgetting to set the date, I quickly fixed this. Similarly, I disabled the default setting that stores files in date-based folders, instead directing everything to a single PENTX directory to match my workflow. Recently, I discovered the option to add photographer and copyright information to image file metadata. This seems particularly useful given proposed U.K. legislation that would weaken automatic copyright protections, even though most photographers oppose these legal changes.
A camera's true value lies in the quality of its images, and I'm pleased with what the K5 II produces. The larger file sizes mean fewer images fit on a memory card, though increased SDHC capacities help offset this, even as I avoid excessive shooting. While using the camera, I was surprised to find apertures like F/14 and F/18, as I was used to values like F/11, F/13, F/16, F/19, and F/22. Most traditional values remain available, so there's not a complete departure from convention. Similarly with shutter speeds, I noticed 1/100 and 1/160 where I expected only 1/90, 1/125, and 1/250. These additional options provide more flexibility and potentially make achieving correct exposures easier, though what constitutes "correct" should be determined by the photographer, not the camera's algorithms. So far, I've mostly used ISO 400, except for some evening woodland testing shortly after getting the camera.
While I've been meaning to share my thoughts on the K5 II since acquiring it a few months ago, I needed time to organize my ideas. Initially, I felt overwhelmed by how much there was to say, even more than what you've read here. There are still features to explore, like white balance adjustments and their effect on image quality. After discovering its shake reduction was switched off, I'm also reconsidering my K10D, especially since this might explain the quality issues I mentioned earlier. Using my tripod more consistently would be another improvement. Clearly, I have many more photographic explorations ahead.
A tendency for overexposure?
14th July 2010A recent trip to Sweden saw my Canon PowerShot G11 being put to rather more use than was expected. If I had known what might have been coming my way, I may even have eschewed the principle of lightweight packing to bring along my Pentax DSLR. Nevertheless, the little Canon did whatever was asked of it when light was plentiful.
Once thing that I have noticed in comparison with the Pentax is the Canon's tendency to overexpose a scene. To a point, this can be explained by the former having proper spot-metering and the latter having the less specific partial metering. In fact, that might explain why a Canon EOS 10D SLR in my possession has the same tendency. Maybe it's time to make more use of the Sekonic light meter that I have, but that adds bulk that doesn't fit in with the idea of carrying a compact camera around with you.
That leaves getting more practice with exposure corrections at processing time (I do capture all my photos in raw format). Going further, I am finding that the same consideration appears to apply to image sharpening too. It's almost as if you need to develop a feeling for the results produced by a camera before satisfaction with any acquired photos will follow. Having decent lighting at capture time and not having muck on the sensor helps too, as I have discovered with the photos made used my Pentax K10D on a recent visit to Arran and Argyll. The state of the sensor needs sorting (even if it has an anti-dust system on board) but I sometimes wonder if my judgement of lighting is what it used to be or whether my aspirations have gone too high. Maybe I need to slow down a little to set aside time for working on getting better results and with the right light, a quantity that should come with autumn and winter. Meanwhile, I'll stick with making the best of the British summer.
Why the manual step?
18th January 2010One of the consequences of buying a new camera is that your current photo processing software may not be fully equipped for the job of handling the images that it creates. This especially manifests itself with raw image files; Adobe Photoshop Elements 5 was unable to completely handle DNG files made with my Pentax K10D until I upgraded to version 7.
As things stood, Elements 7 was unable to import CR2 files from my Canon PowerShot G11 into the Organiser, so it was off to the appropriate page on the Adobe website for a Camera Raw updater. Thus, I picked up the latest release of Camera Raw (5.6 at the time of writing) even though it was found in the Elements 8 category (don't be put by this because release notes address the version compatibility question more extensively).
Strangely, the updater doesn't complete everything because you still need to copy Camera Raw.8bi from the zip archive and backup the original. Quite why this couldn't have been more automated, even with user prompts for file names and locations, is beyond me, yet that is how it is. However, once all was in place, CR2 files were handled by Elements without missing a beat.
