OK....so the 14mm Olympus lens produced results like a 28mm lens on a
film
camera. What do you need a much shorter lens for? Are you photographing

inside tight spaces?

Yes. Interior compartments of boats.
The main lens I use for interior photos with the Contax is a 19-35mm.
At one time, I used a 28mm fixed lens and found that I really needed to
get down to the 19mm size fairly frequently.

It looks like it takes a about 12mm Nikon or a 10mm Olympus lens to get
that 19mm "view" I'm used to with silver film.

Bottom line is that I won't get by merely with the kit lens supplied
with any of the "affordable cameras".

Offshoot of this research seems to be that among the cameras with
three-figure price tags the Rebel XT has the potential for taking
photos of the highest resolution. The XT is rated at 8 megapixels, and
the 1.6 focal length multiplier indicates it also has a larger imaging
area.
Now if only the lenses for the Canon felt a bit more
"industrial".........


Be aware that sensor size plays a role. Not the number of pixels, although
that's important too. Simply the physical size of the sensor. There are two
reasons for this. Most important, larger sensors give higher quality
results. For the same number of pixels, a larger sensor allows each "well"
or pixel on the sensor to be larger. Larger means more sensitivity to light
and less noise.

Second, larger sensors give a wider view for the same focal length lens. If
the sensor was the same size as a 35mm negative then the lenses would give
the same view on the digital SLR as on the film SLR. If the sensor is 1/2
the size then the lens will give a view equal to twice the 35mm equivalent.

Size does matter!
