RE: [artshow_photo] Camera Investment?????

Perry,

If you are contemplating using older film lenses with digital bodies, aside
from the physical and electronic compatibility, there are other issues you
should probably consider.

Lens made in the good old days were optimized for film, where design
decisions were made by lens mfgrs to optimize certain qualities often at the
expense of others. Chromatic abberation, distortion and light falloff were
fairly important, and since 35 mm film had certain hard limits as far as
resolution and ability to capture and render detail, they could sacrifice
some lens resolution. The current crop of digital cameras can eat up all the
resolution you can throw at them, and you can deal with contrast, sharpness,
light falloff, CA and distortion fairly easily in post processing.

Another consideration is handling. These days 5-8 frames per second is the
new norm, autofocus systems in the cameras are very sophisticated and
provide many options for customizing how the camera will behave, and lenses
are now designed with shorter focusing ramps, it is now possible to shoot
moving subjects by simply holding down the shutter and the majority if not
all of your images will be in focus. This is not possible with manual focus
lenses. Also, digital cameras lack the optical focusing aids of groundglass
screens with microprism areas and center split images. Its really hard to
acquire focus accurately when in manual mode.

You might want to take a look at:

His lens evaulations are on target, carefully and thoughtfully written, and
he has lots of manual glass in digital body evaluations. You are most likely
to find what you are looking for here.

I would suggest getting a used D200 for around $500 or a D300 for around
$900. If you decide to have the camera modded to change the focusing screen
so you can use older glass, or even if you just want something to try out in
the meantime until the D400 (or whatever they are going to call it) comes
out - its not a bad way to get involved. You can always sell the body for
close to what you paid for it.
