Again, thanks for the information. I think I'm just going to get another Zen (or Pentax DA10-17) from ebay. From what you guys told me, this lens was some sort of hybrid of multiple zens put together to make it (sort of) work. I'm going to keep this zen and maybe tinker with it when I have the time.

Thanks Lowell and Steve.
Here are some more pictures. The first picture I got from ebay. The second picture is the back of my Zen (no "c" "M26.5x0.5"). And the third is my adapter. So, more questions:
1. Does the back filter necessary ?
2. How to adjust/set infinity focus?
3. Right now, the focusing appears better (but still not sharp) when the object appears further. When it's closer (< .5 m), it looks like if I'm using a soft filter.
4. I think I have the correct M42 adapter. If not, which one should I get? But it definitely needs an adapter (because I tried :))
5. I'm not seeing any switch whatsoever on this lens. Where is it located usually?
Again, thanks. This has been very educating.

Thanks guys. I didn't know there is a k-mount version. So, I'm guessing the k-mount version doesn't need an adapter (which will be really sweet).
This one is $50 off craigslist. I was hoping that I don't have to spend $200+ off Ebay. It looks like that's what I will be doing. Does anybody ever use this for lens for star trail or aurora shots?

Hi guys,
Recently I purchased a Zenitar 16/2.8 Fish-Eye lens. This is my first M42 SMC. Not sure why, but I can't seem to get a quality picture with this lens. Simply said, It's not sharp. So I'm hoping you guys can help me out here:
1. When I turned on my K5, it asks for whether it's 15mm, 18mm, etc lens. But no 16mm. So what should I choose?
2. Not sure what the correct term is, but Googling "grease on lens" gives me entirely something else. So I'm just going to show you a picture below. Is this the cause why my pictures doesn't turn out sharp as I wanted to be?
3. If not, what can I try? I saw some post about adjusting the focusing ring, but not sure how to do that.
Any help will be appreciated. Thanks.

From personal experience:
1. Was in Fairbanks, Alaska. Shooting aurora with my Tamron 18-250. The result looks good, but cropped. I wish I have an FF so I can see what I've been missing.
2. Was taking pictures of friends in a costume party using my 50mm f/1.4. Room too small and too crowded. I couldn't stand far enough to capture the bottom part of the costumes.
3. Just bought a Zenitar fisheye lens (16mm). Couldn't get that "fisheye effect" since I used it with my K-x.
There are many reasons for Pentax to start investing in FF. But what I really want to know, why they haven't done it yet ? Why the wait ?

There seem to be a "Type 3" battery grip out there for sale on ebay. It looks almost identical to "Type 2" with the exception of the "AF" label is printed on the side of the button instead of on the button. I read somewhere that after a while that the buttons' labels got scrubbed off. Maybe that's why they put the label on the side. Does anyone here own one, and what do you think compare to the other two types ?

Hi guys,
I lost my 1-page manual that comes with this flash. I'm trying to see if any owner of this flash knows how to disable its auto-off feature. The flash turns off itself after not being fired for awhile to save battery (it says OFF on the display).
I'm trying to make it as a wireless slave using Cactus V wireless trigger. Apparently setting it to "S" only sets the flash to optical slave mode and doesn't respond to my wireless trigger. So I have to set it to one of the curtain modes.
This flash is also sold as Sakar 952AF/PEN, Soligor DG-420 Z, Dörr DAF-42, Vivitar DF400MZ.
Thanks.
