Back in 2006, I wrote a post which listed all the cameras I've owned through the years and made a presumptuous conclusion that my days of upgrading were over since I obtained my "Dream Camera", a Canon 1DmkII. Silly me..
Since then I've had 3 bodies:
Canon 5DmkII - A great image sensor trapped in a slow focusing, mid-grade build quality body.
Canon 5DmkIII - A super image sensor wrapped in a solid body and endowed with the modern AF system of the top of the line 1Dx. An excellent camera that should do more than any photographer short of the sports shooter could ask for.
Canon 1Dx - The top dawg, IQ, high ISO capability and dynamic range that made me choose it, and its premium $$, over the 5D.
My glass collection has also grown to now include: 15mm 2.8 fisheye,14mmF2.8, 24mm 3.5 TS-E II, 17-40F4L,24-105F4LIS,50F1.8, 70-200F2.8LIS II,85F1.2L, 100mmF2.8L Macro, and my baby the 300F2.8L.
So NOW am I done?...hardly. I know better. I can probably say that I'm done with DSLRs at this point as my dream camera now is a one of the new Compact System Cameras. As sensor technology advances, these smaller sensor formats will keep all the advantages of lighter, more compact bodies and lenses without any compromise in image quality. Manufacturers are pretty close to hitting the sweet spot and I'm about to sell my 5DmkIII to move to one of these gems. Leading the pack is the Fuji ex-1 followed by the Sony Nex-6 and with the awesome lenses available for the micro 4/3s systems, those are high on the list as well...
