I collect old cameras. But I like to use them as well. The ones I use most are:

Leica M2 with CV 15, ZM 35, Summicron 50 and Elmarit 90 lenses

Zeiss Ikon Contax IIIa, mostly with Sonnar 50, Biogon 35 and CV 21

Zeiss Ikon Super Ikonta IV (medium format)

Pentacon Six (medium format)

I also do pinhole photography with two cameras:

Zero Image 6x9 (medium format)

Harman Titan (4x5" large format)

I develop bw film at home, but usually scan the results, but I do have a dark room that I wish to use more.

Digital cameras:

Canon EOS 500D, mostly with the 10-22mm

Sony Nex-5

Canon G7 X

Are mirrorless compact digital cameras the future? I'm impressed with the image quality from the Nex, but not the lenses and the ergonomics. Time will tell if I invest more in the Nex system or get an upgraded EOS body for APS-C (or maybe both). What I really want is a full frame sensored camera that can take Leica M-mount lenses at the price of the Nex...
