Re: Instead of wasting resources on a new mount and ILC, how about that FF DSLR

As it is now, if or more likely when they release a FF DSLR, the number of FF K-mount lenses is extremely small. You basically have the 31 f/1.8, 43 f/1.9 and 77 f/1.8 Limiteds, the FA 35 f/2 and 50 f/1.4 and the 50 and 100 f/2.8 Macro lenses. And of course the new DA 560 f/5.6 for a grand total of eight lenses. No wides, no zooms of any kind, only 3 Limiteds, two normal, two macro and one $7000 super telephoto.

There are a number of DA lenses that cover FF, as shown by mounting on film cameras and results posted in a thread at Pentax Forums: 35 f2.4, 50mm 1.8, 40mm 2.8, 70mm, DA*200, DA*300. I had not heard that the DA 560 is FF compatible.

So the lens upgrade path for APS-C DSLR users, the majority of Pentax users, is dicey at best. And for K-3 users, there are some fairly sizable holes in the APS-C lens lineup. For example they cannot keep releasing excellent bodies like the K-3 and kitting it with the 18-135. Such a lens that on 16 mp wasn't cutting it, just doesn't make sense at all on the 24 mp K-3. It puts the camera in a bad light and it needs to bet updated or discontinued.

You are wrong about the 18-135mm. It is better in every way than the 18-55 WR, other than wide angle distortion which is easily fixed in the camera or in post. It is as good as anyone's 18-135, and beats them all by adding weather seals. http://www.dpreview.com/forums/post/52109191 It also beats my DA 18-250 handily, a lens with a good reputation around here.

Here's an excerpt from the ePhotoZine review of the K-3:

"Lens Performance -The SMC Pentax-DA 18-135mm f/3.5-5.6 ED AL [IF] DC WR was supplied with the camera and it is an ideal companion for it. Clearly the lens has enough reserve resolution to handle the increased pixel count and it performs better with the K-3 than with the K-5 cameras. CA seems reduced and images are cleaner. It would confirm that it is the combination of sensor and lens that dictates final image quality, not just one or the other.

The 18-135mm produces clean, crisp images and complements the K-3 perfectly. Flare is well controlled, although it is always a good idea to use the included lens hood."
