Originally posted by baro-nite Yes, that works, in the same way a 50 or 55mm lens works as normal on FF. Long normal, if you will. I just think if Pentax is truly committed to APS-C, it makes sense to offer a true normal prime, i.e. 28mm, instead of simply recycling an old optical formula from the FF days. 35mm the standard moderate wide FL on FF, but is a little odd on APS-C IMO.
After using a 55mm Takumar
as the standard lens on my Spotmatic
for many years back in the previous millennium,
I've always been comfortable
with that angle of view (45 degrees diagonal),
now offered by 35mm on APS-C.
It works well with a moderate wide-angle
(60 degrees diagonal)
given by 35mm on 135 ("full frame")
or 24mm on APS-C.
So I'd really like to see the DA*24/2 WR
that is currently the top
lens in Ron Hendrik's poll:
