I've used a lot of different cameras since I began this humble blog. Some I still use; others I've sold, or still own but don't use. The list of those I've used the most so far includes:
Nikon FM3A (own but seldom use)
Olympus OM-1 (own but seldom use)
Canon EOS F-1n (own but seldom use)
Canon EOS 30D (sold)
Olympus E-520 (sold)
Pentax K5 (returned to Pentax)
Canon EOS 7D (returned to Canon)
Canon 5D Mark III (returned to Canon)
Nikon D7000 (sold)
This doesn't include cameras I've used for a week or less because of an assignment, a user review, or general curiosity. As you can see, I favor mid-range cameras; those that are somewhere between the smallest and largest and between the most and least expensive. I suspect most readers of this blog have similar tastes, which is why you may be interested to know what I'm using now and why.
At present, 90% of my work is done with a Canon EOS 60D and a Nikon V1. I bought the 60D to replace the Nikon D7000, which I was never able to get to focus consistently and reliably. (This was my personal experience. I've only used one D7000 and have no idea if this problem is widespread.) Aside from the focusing issue, my main reason for buying the 60D was so I could use the four Canon EF lenses I still own and rent practically any other lens I might need. Even though I seldom take on pro assignments these days, I still want to be able to should the need arise. The EOS 60D also allows me to shoot with portable and studio flash units. This is something the Nikon V1 can't do.
Because of its size and weight, the 60D is my preferred rig for shooting at home, when portability isn't an issue. That said, the 60D with a 28mm f/2.8 EF is still small and light enough to carry all day on a wrist strap or in a small shoulder bag. Because I don't own any Canon lenses slower than f/2.8 and the 60D has a much larger sensor than the V1, the 60D is also better for available light shooting without flash. Fast lenses reduce the need to shoot at absurdly high ISOs and then complain about the results.
The Nikon V1 is my "everyday-carry camera." I was initially attracted to it because of its small size, low weight, and sturdiness, which make it perfect for travel, outdoor family activities, or an afternoon of street photograpy. Interchangeable lenses and a built-in eyelevel viewfinder made it even more attractive. What sealed the deal was its lightning fast, amazingly accurate focus and above-average metering accuracy. I know some photographers are put off by the V1's smaller sensor, but to my mind these folks aren't much different from film photographers who lugged around Hasselblads because 35mm cameras produced "inferior results." Either you appreciate the small camera esthetic or you don't. I do.
All in all, these two cameras cover enough bases for me that I have little need or interest in buying anything else--mainly because the extra money spent wouldn't result in enough more image quality or convenience to make it worth the cost. If your situation is anything like mine (more than enough good cameras, not enough time), this could explain why camera sales have slowed considerably over the past six months. What about you? Do you have enough cameras? If not, will you ever?
