Out of curiosity and a candid question : why do some of you use more than 10 cameras ?
Hmm, good question.
For the cameras I use most I nearly always use two bodies - either with two different films or so I can use two lenses without changing. Whether I'm shooting RF or SLR depends on a few things, but mainly on whether I want to shoot wide or long. So at the moment, I'll tend to carry an M6 and an M2, or an Olympus OM1 and OM2. Or sometimes it's a combination - recently I went away for a weekend with the M6 + colour slide + 40mm lens, and the OM1 + B&W + 100-200 zoom.
Alternatively, when I want to use ultrawide lenses, my RF kit will be one of the Ms plus my Bessa R4A. I use it mostly with a CV 21/4 and there's nothing that comes close - the viewfinder is stunningly good. (On my last spell in Thailand I took M6, R4A and CV 21, 28 and 50 lenses, and that proved to be a great combination - I'm still agonising over what to take next time, and as I'm flying on Friday I really need to decide pretty quickly
🙂).
I also have a Leica CL, which I like to use when I want to do some shooting when I'm out but photography isn't my main concern and I don't want to carry a camera kit around - it easily fits in a pocket, or in a bag with other non-photo stuff. (And the CL with a Summicron-C 40 is so nice to use
😉)
So that's 6 accounted for so far.
I also use an Olympus XA and XA4, one of which is always with me in a bag or pocket when I'm out not taking photos - which one I take is pretty much down to whim, but I like the variety and the challenge of not really being sure which I have with me until I need it.
Medium format - main camera is a Bronica ETRSi with a few Zenzanon lenses.
So that's my main cameras, count = 9.
The rest of the cameras I use are really for fun, because I just like using well-designed and vintage cameras.
I've got a couple of Kodak Retina IIa cameras - one each of the European and American versions. I use them occasionally just because they are so gorgeous and I love using them - the IIa is the peak of the Retina range in my opinion, and with both lenses being superb I get great results from them.
I also have a bunch of FSU gear, and again I use various bits from time to time just because I enjoy using them - FED 1, FED 2, FED 3B, Zorki 3M, Zorki 6 are all great classics that deserve to be used, and they all get taken out from time to time. How many's that now? 16, I think.
I have a Yahica-D TLR that I also like to use from time to time - I like the TLR approach and I like 6x6 negs. Also 6x6, I have a recently rediscovered Ensign Selfix 12-20 folder (which I went out shooting with last weekend).
Also a couple of fixed-lens RFs - a Ricoh 500G and a Vivitar 35ES. I use these sometimes the way I use the Leica CL - great to carry in a pocket or a bag when I don't want to carry much kit. (Actually, they work pretty much like a fixed-lens CL, and since I got the CL they don't get as much use as they used to, but they're not redundant yet).
Oh, I also have a Pentax MX, purely because I aways wanted to try the Pentax 40/2.8 pancake and I saw the two together cheap on eBay last year some time. It's fun to use occasionally - I really like the 40mm focal length.
I think that's 21 so far, and it's all I can remember now (which is more than I could remember when I first replied on this thread) - but I'm sure I must have missed something
😉
So overall for me it's practicality and flexibility with my main cameras, plus the fun of keeping various old cameras in use instead of them gathering dust somewhere.
