Hi
It's truly a good time to be a photographer - today we have a wealth of choices of systems....
My main objection against APS-C cameras of the DSLR mould was the lack of prime lenses with the equivalent focal length. I experienced this as early as the venerable Canon D30, the first *affordable* DSLR, where I was always trying to pretend my fixed 20mm lens was a 35-ish lens. And there were no equivalent for focal lengths like 28mm, that is also a fast lens. (the closest is the old Tokina 17mm, but that's f3.5).
So when the full frame cameras came down in prize (and SIZE), I wasted no time jumping to full frame. To me, I enjoy using my D700 with smallish prime lenses like the 24mm f2.8 AFD, the 35mm f2 AFD or even a simple 50mm f1.8 AFD. True the D700 is bigger and heavier than other APS-C cameras, but it's solidly built, with a large viewfinder and more importantly, I can put those small primes on it.
In fact, I carry the D700 with these fixed lenses almost daily. (mostly with the 35 though..)
To bring this back on topic, today the X100 has largely replaced the bulky DSLR in the bag for daily walks. I guess I can deal with the APS-C sensor now because the lens is fixed AND it's a fast 35mm f2, so I'm a happy camper.
I'm very glad to see the X-Pro1 being launched with just fixed focal lengths lenses - and not just fixed focal lengths, but FAST fixed focal length lenses. It's also very cool to see them with the traditional focal lengths of 28, 50 and 90mm equivalents. This makes the APS-C sensor more acceptable to me.... Which other manufacturer except Leica releases new systems with just fixed primes and NO flash????? It takes plenty of balls / guts to do that
Fujifilm has said this will be first in the series of X bodies and lenses, and I see no reason not to believe them. They seem to be in this for the long haul.......
