Originally posted by yyyzzz While the f1.8 is great, it is perhaps overpriced. It is in the same price range as the Zeiss one. It is a result of supply and demand. Most buyers are perhaps collectors...
Which is a shame, as the A*135 is a fabulous lens which deserves to get used...
I don't mean to take away from the great work in this thread, and really many of the excellent shots shown here reflect more the talent of the photographers, but I have owned both the K135/2.5 and A*135/1.8 (at different times, mind you) and the A*135 is truly deserving of its reputation. The K135/2.5 is no slouch either, but it is 2nd best behind the A*135 amongst the Pentax 135's.
Here is a topic I started a while back on the A*135. Later on it also contains some comments about the other 135's, including the K135/2.5.

That said, the K135/2.5 is an excellent performer and I still wish I had mine.
