RE: Digital slide camera, was Re: off-topic digital camera suggestions

I have been using a Fuji finepix slr for copy work recently, with a
Nikon 55mlmacro lens of considerable vintage, and am not having any
trouble getting good clean shots with no distortion. I'm starting
research on converting all my school's slide production to digital so if
anybody wants the information, or has any to share, please let me know.

There's really a lot less to this than some of the manufacturers' hype
might lead one to believe. All decent sensor designs have microlenses
over the pixel wells, and exhibit angular sensitivities fully compatible
with the widest of wide angle lenses. Sensors are generally a bit more
reflective than film, so a few badly-designed lenses with concave rear
elements that unfortunately have reflective focal lengths similar to the
rear-element-to-image-plane distance exhibit ghosting, but they do this
to a lesser degree with film, too. Other than that, there is no issue.
I've cobbled all kinds of optical elements, including ultra-wide lenses,
to my 10D and have had not the least hint of any problems. Yes, I
realize that some manufacturers persist in using sensors without
microlens arrays, but I'm inclined to think they shouldn't be taken
seriously by anyone who cares about their images. They're just trying
to sleaze by on the cheap.

Best regards,
