Adobe Bridge CS5
I've got a folder where I save pictures I want to be able to look at again. Maybe for composition, lighting, Photoshop tricks, or maybe just because I like them. It's a mixture of Fashion, Street, Candid, Food...whatever. A lot of these images still have their EXIF data, so as I was looking through them in Bridge the other night I decided to write down all the camera models and focal lengths and put together a survey. I converted all the focal lengths from APS-C, APS-H and Medium Format to 35mm terms just to make it easier to read.
20% - Canon EOS 5D Mark II
15% - Canon EOS 1Ds Mark III
9% - Ricoh GR Digital III (this is probably an outlier)
7% - Nikon D3x
5% each - Nikon D3, Panasonic GF1
4% - Phase One P45+
3% each - Canon EOS 1D Mark III , Canon EOS 5D, Nikon D2x
2% each - Canon 1Ds Mark II, Nikon D300, Nikon D700, Nikon D90, Phase One P30+, Phase One P40+, Phase One P65+
1% or less each - Canon 30D, Canon 40D, Canon 450D, Canon 7D, Canon Rebel XS, Canon EOS Digital RebelXSi, Hasselblad H3DII-31, Hasselblad H3DII-39, Leica M8, Leica M9, Nikon D3s, Nikon D70, Nikon D70s, Nikon D80, Nikon D5000, Olympus E-300, Phase One H25, Phase One P25, Ricoh GR Digital II, Ricoh GXR P10, Sinar Hy6/Sinarback eMotion 75II, Sony DSC-F828
Nothing too surprising here, except perhaps the strong showing by Phase One. The GRD3 numbers are probably inflated because I have an interest in the camera. Let's move on the the lenses.
17% each - 50mm, 28mm
14% - 70mm
9% - 35mm
8% - 85mm
6% each - 24mm, 40mm
5% - 60mm
4% - 100mm
3% - 90mm
2% - 110mm
Everything else got one percent or less. Although there were a few trends even in that. If you add everything between 90mm and 110mm together, it's about eleven percent. Combined 70mm to 85mm is 24%. And there's another two or three percent bunched somewhere around 150mm. The shortest lens was 12mm and the longest 220mm.
This is all fairly unscientific. None of the images were chosen at random, they're images I like, but they're mostly from professional, working photographers.
