Hi,
I was hoping that someone on the list could help me figure out which of
these Pentax zoom lenses performed the best. I would be using these on the
*istDS, so the crop factor might possibly be something to consider. I think
I also read somewhere that the digital bodies especially need a lens with
higher resolution, because of their smaller image size. Also, if one of the
lenses has been reported to be slightly soft in the corners on 35mm film,
that might still be okay. With the digital body's smaller image size, those
"corners" no longer exist -- if you know what I mean. ;-)
Here is the group I'm tentatively considering:
SMCP-DA 50-200mm f/4-5.6 ED
SMCP-FA J 75-300mm f/4.5-5.8 AL
SMCP-FA 100-300mm f/4.7-5.8
I realize that the first lens is the only one of the three designed
expressly for the digital bodies. I also realize that it's the only one
with internal focusing, and the only one which won't rotate my polarizer
during focusing.
However, which one should provide the best image quality?
If there is anything else I should know, feel free to mention it, but image
quality when used on an *istDS is my main concern for now.
thanks,
Glen
