Originally posted by 2351HD There seemed to have been quite a few people with faults/complaints and issues with the 25. Perhaps it was a faulted design and that's why they decided to cut it.
I bought the 28-45 due to the fact that when I need wider than 22mm eq, I would need at least 15-16mm so I use another camera for that work.
I had the 25mm, which worked perfectly without any issues, until when the 28-45mm came out I bought that, sold the 25mm and now I use a Pentax K-3 with a Sigma 10-20mm for my ultra-wide work. With a Pentax 645-to-Pentax K adapter, this also works as my backup, should anything happen to the 645Z when I am in the field. This way I get U-W angle, backup, and as a plus I can use the same batteries, chargers etc for both cameras, menus are pretty much the same, etc. I am pretty happy with this setup so far
