Lens review/comparison website
There are some scattered reviews.
Check these out for starters:

I too have the *istD and find that the AT-X range Tokina lenses are very nice indeed - the 24-200mm is a very useful brute. All are large though, with whopping 72mm filters. They review well too

Hope this helps!

I have mainly been shooting digital for the last couple of years (with a Fuji), and using my Z1-P with a Sigma zoom when I do shoot film (usually slides).
Yesterday I got some prints back from the local processor. My wife (no photographer!) had borrowed my old Super A and 50mm 1.7 for a trip to New York and came back with stunningly sharp, flare/distortion-free pics with high contrast and lovely colours. She managed to focus them, too, and the camera exposed perfectly, despite the conditions. In New York, everything is generally either brightly-lit or in dark shadows.
The results from the Sigma zoom looked terrible by comparison. I had never appreciated how big the quality difference was between a rather so-so zoom and an excellent prime.
Sod the convenience. I'm going back to prime lenses or very highly rated zooms with a small zoom range. Thank you, Pentax, for increasing the usability of M lenses on the *ist D.
I especially like 'stans' site.

I'm currently considering buying an *ist D. I don't have any existing lenses so I wanted to know more about them. Is there a website that lists compatable leneses - hopefully one that includes reviews and side by side comparisons with other compatable brands? I would only be interested in the newer AF lenses, but I realise that with the recent firmware many more lenses are 'compatable' at a basic level.
Does such a site exist?
many thanks,
Andrew
