In my (many) years of 35mm film photography, prime lense selection always
seemed raher simple:
50mm gave a perspective that seemed natural to the human eye and could be
considered "standard"; 35mm was moderately wide angle; 28mm rather wide
angle and 80mm good for reducing depth of field in portraits.
Now that I have been seduced to the EOS400 world, with its accompanying
1.6 focal length multiplier, it all seem rather more awkward.
In an attempt to get a "standard" lens I have bought an EF 28mm f2.8. This
works out as quite visibly more wide angle than a 50mm on a film camera.
I did try an EF 35mm but its equivalent 56mm was markedly narrower in
field of view than a 50mm on a film camera.
The only easy one was the 50mm which gives me the 80mm portrait lens I am
used to.
So do I just have to get used to this or will some "standard" small sensor
lenses eventually appear? Or is this why there are so many zooms about?
