Thoughts, feelings, and techniques behind the photography of Derrald Farnsworth-Livingston.
The third item I am going to address is ISO performance. There has been quite a bit of discussion on the net surrounding the noise levels at higher settings. Since this is more of a real-world look than a technical review (there are lots of sites dedicated to that), I am going to simply discuss what I have seen. The ISO levels seem better than the Canon 5d by somewhere from about 1 to a little less than 2 stops. This means that greater detail and less noise is available at higher ISOs. On my Canon 5d I never had any problem dialing the ISO up to about 800 for some shots. 1600 was about my absolute maximum for retaining detail. Beyond that I found that I had to use noise programs fairly liberally. All the wildlife photographs on this blog post were shot using a minimum of ISO 400 up to 640. This allowed me to achieve shutter speeds that would stop the action, but allow a little blur to show the movement of the birds. At these speeds there is virtually no noise.

Canon 5d Mark II, 50 CM, f/5.6, 1/50 sec., ISO 6400
To follow up with a little more testing in a (little) more controlled environment, I decided to purposely photograph my stationary cats at ISO 6400. I found the noise was well-controlled and definitely an welcome improvement. Another nice feature is that the ISOs are set at third (or half depending on your preferences) stops up to 6400. That means that I have good selection of ISO speeds between 1600 and 6400 to use without changing a full stop. On the Canon 5d, after 1600 the only choice was a full stop up to 3200. Beyond 6400 on the Canon 5d Mark II, the noise makes the image degrade to a point where I would find it unusable for a print, unless I was applying liberal use of filters and noise control. Even then I question it's real-world application for my primary work. In a pinch, though it is useful to capture the shot in conditions that I would have been unable to get it before, although it may just frustrate me in post-processing.

Overall, I find the Canon 5d Mark II to be a worthy successor to the Canon 5d. It doesn't have everything I wanted (I would like DEP mode back, but that's just me I think), but it has enough to warrant an upgrade. There are always function and features to be added and on future posts I may comment on a few of those. Check back to see what new feature I might dig up.
One last note, I processed all these photographs from RAW using Adobe Photoshop CS3 and the free DNG converter found here. Adobe conveniently ended RAW support for CS3 right before the Canon 5d Mark II was released (and well after it was announced). Some couldn't even get a copy of CS4 prior to receiving their camera! While I agree with drawing a line in the sand for support, most companies, including ones like Microsoft offer support for the current version and one previous. I find that ending support as a way of forcing upgrade when the product (CS4) isn't even released a bit much. For those who cannot afford the upgrade there are several support sites dedicated to the DNG converter (such as scripting and processing) and I recommend that you look into those.
