My last film camera is likely to be the Hexar RF Limited I bought a little over a year ago. I cannot see a need to add another film camera, unless I get a 5x7 LF camera, which I doubt I will.
Eventually I think I will add two digital cameras, one small pocket sketch pad camera like the GR-digital (with faster RAW mode and hopefully a 35 lens) and a digital M mount RF camera. Since I doubt digital cameras will last more than about 10 years and I am 41, I guess that it is likely that I will need to re-iterate these digital cameras a couple of times. Well, that is if there finally are digital cameras available that I find worth buying, which is not the case today, though I think we are getting close to that point.
On the other hand, if my Hexar RF dies, I will still have the Leica M2 and M4 and they will most likely last longer than me, so no need to get another film camera.
