Pentax smc DA* 55mm 1:1.4 SDM review - continuing
Aug 1, 2009

We will continue to post here

Some of the samples were shoot with the K-7.

Pentax Quality Control strikes again:

"Unfortunately, though, we have serious concerns over two issues with this lens which have to temper our enthusiasm; namely optical alignment and autofocus (which are quite likely related). Over the course of what has become a rather protracted regime of testing, we've looked at three samples of this lens; each has shown a clear tilt to the focus plane, most pronounced in the first sample, and least problematic in the last (which we finally decided to use for the published tests)."
