Photozone Pentax Lens Reviews Updates

Continuing with LBA week, I just wanted to point out that Klaus Schroiff,'s resident Pentax lens enthusiast, has posted a whole slew of new and updated lens reviews taken with the K10D this month. Keeping in mind that lens characteristics are different between sensors and camera models and even your RAW conversion process (he uses ACR), it makes sense that many of the lenses are all reviewed with Pentax's current top-shelf camera, the K10D. What I like about Klaus' reviews are that he cuts right to the chase with pertinent studies of lens distortion, vignetting, CA, and MTF acuity (sharpness) across a number of apertures and zoom ranges. In fact, it's easy to take in a whole review very quickly and understand right away what his tests, using Imatest, show to be the best apertures and focal lengths are for lens performance. Also, there are usually at least a half-dozen sample images at full resolution so you can get a better idea of real world practice with the lenses.

If you're looking for data on lenses with the K10D, this is probably one of the best places to start.
