Canon R
More specifically Canon R mirrorless full frame, full spectrum modified, used with RF-EF adapter with filter slot, and a range of lenses: Sigma 12-24 f/4.5-5.6 DG, Canon 24-105 f/4L ii, Canon 70-300 f/4-5.6 DO, Canon 100-400 f/4-5.6L ii.
The 100-400 is a new addition for a particular purpose, after which I will be evaluating which of that and the 70-300 DO to keep. The former is noticeably sharper as well as slightly more powerful, but a lot larger and heavier and so less likely to be carried unless for something very specific.
The filter slot adaptor means convenient use of a single set of filters, and the polariser one also has the advantage of providing easy insertion and fingertip adjustment regardless of size of lens and lens hood.
I was waiting for full frame ever since I went digital with my previous camera (Canon 500D), the R being the first that was affordable and relatively light. It is also small, but its slimness only realised with RF lenses - that is a disadvantage of using the adaptor, but the advantages of keeping my old lenses and the very significant advantage with filters makes the added depth (closer to that of Canon’s full frame DSLRs) tolerable.
I also have an Olympus TG4 with underwater housing (the camera is also a full underwater camera in its own right, but this provides belt-n-braces against leakage, having had that once with a previous camera on the first day in the Maldives, so no photos!). Also an Olympus take-anywhere-including-underwater (providing lightweight point and shoot plus second backup underwater).
My rather older Canon AE-1 is in a cupboard, not being able to face selling for the peanuts it would raise - initially kept when I went digital, but usage all but stopped when I sold all my darkroom gear. And I think I have my very first camera, a Zeiss Icon bellows 120-rollfilm (12 exposure) that I smuggled into the first gig I went to and snapped Ritchie Blackmore playing a Gibson - but sadly the picture got lost in the midst of time.
