Oh, so wait, the UV filter is factory installed, and it is just the 3 color filters that can be interchanged? I could not care less that I don't have the color filters.... is there anyway for me to find out for sure if I have the UV filter installed? Zenit got back to me and said I can order the filters, however aside from the price of about $100 and the shipping to the US that they said would be over $60 (and take over a month) does not make sense since I picked the lens up for $150 and I could just get a new one for $250. I need to somehow find out though because being that is a used lens, I think B&H only gives me a few days to return it....
If it helps at all I just took 3 pictures of the back of the lens, the one from the side you can see that surrounding the actual glass opening in the middle, there is a black ring that is raised and has grip notches (the type that would make something easier to turn, however turning it doesnt seem to move it and I don't want to try harder out of risk of damaging it). can that possible it?

OK fair enough. I will take a few pictures right now in manual mode at 1/25 or 1/50 depending on how the exposure is, at ISO 100, with the ring completely closed down. Thanks for the explanation of the M42. With that understanding mine is definatly the K bayonet mount. BTW, I have taken a few peoples suggestion of trying to meter in green mode, but unless I am doing something incorrect, it cannot happen because when switched to green mode, the camera goes into Av mode with auto exposure and there is no way to overide it and the LCD shows nothing for shutter speed, and the aperture says F - - and nothing can be altered. I should also mention something that I realized I neglected so far, that like anytime you attach a manual lens, it asks you to enter the focal length, which I enter as 15mm (lens being 16mm) because it is closer than the next option of 18mm.
I am sorry if I am frustrating everyone, I am trying everyones suggestions and I really do appreciate the help.

I know that I have to shoot in manual mode. As I said in a few posts, I did that and the results were the same.

OK, I will try that, thanks! I went previously to Zenit Cameras and sent them email at support@zenit-camera.com via their support link Zenit Cameras (the one that is undeliverable)
I will try your link now.

This is not my only manual lens, I actually have quite a few... I do realize why shooting in Av is an error, you should know that those pictures, the exif data might say they were all shot 2.4, (which they were when in Av mode), but I did know not to use 2.4, I just didn't realize that it was going to shoot that way regardless, thats why after finding that out, i went outside and tried some more pics in M mode stopping down the aperture more. The results were the same however. As far as auto ISO, I only did it to try to troubleshoot possible user error, normally I always force ISO between 80-200. As far as the WB, that I did not try, left it in auto, I am going to go try manual WB in a moment. As far as RAW, I always shoot in RAW, the pics in Flickr were JPG because I converted them for the purpose of uploading. I really do like the framing that this lens allows! Just gotta figure out what these other issues are about. Also another response in this thread stated that the rear filters are in fact needed and that if I didn't get them, I should return the lens. I did not get them, as I stated in the OP. I tried going to Zenit's website and sending them an email on their provided link to see if I can purchase the filters directly from them, however the email was returned as "un-deliverable". Any idea where else I could obtain those filters? I tried ebay and nothing.....

As I said, the used item did not come with the rear filters. I went to Zenit's website and sent an email using the link they provided for the purpose of trying to order them, but the email was returned as not deliverable. I am aware of the fact that the aperture will remain wide open in Av mode regardless of settings. That is why I tried I switched to M mode. I will try keeping it at 5.6 and low ISO and use the green button to meter. Thanks.

Well, if I choose any of the auto modes (other than green of course) it displays on the screen that it is in Av mode. I can put it in manual and it says manual and I can control everything but the aperture. I have tried composing the same scene in both modes, from ISO 80 up to ISO 800. I have also tried auto ISO. I get the same result every time regardless of those settings (other than the exposure level of course). As far as the mount, it was listed by B&H as PK mount, and it specificaly said in the listing that it was not M42. However, I really wouldn't be able to be certain that it is not M42 since I don't know how to tell. The metal mount has the protruding aperture adjuster, but it also of course has the manual aperture dial on the lens. The print on the lens says MC ZENITAR-K 2,8/16 and the sticker on the case that B&H placed says "Zenit 16/2.8 fisheye F/PENTAX K.

I purchased that lens new a couple of months ago and paid about $470 US. I have to say that my expectations of it were far less (considering the low price), but matched with my K-5, I am amazed over and over how well it actually performs!

Hi this is my first post, and am hoping someone can help me out or point out what is wrong. I just got a used Zenit 16mm 2.8 Fisheye for Pentax K mount from B&H Photo. The lens visually looks fine,and B&H had it listed at 8+ condition. I am using a Pentax K-5. When it got delivered today, I naturally wanted to run outside and take some test pictures to see what kind of pictures it takes. The lens automatically goes in Av mode, I tried letting auto ISO run, and tried manually adjusting ISO as well. I tried a whole range of f-stops from 2.4 to 16, both as JPG and DNG. I should not that the lens does not have the 3 rear filters that it would of come with new, but from reading numerous posts, those filters are not important and shouldn't be used anyway.
So anyway, the problem I am having is that once I imported the pictures to my PC, i realized that they all have SO MUCH grain and look very "blocky". My sensor is clean, and my other lens all take fine pictures. I am hoping the community can take a look and some of these pictures and offer an opinion on whether it is a defective lens or if I am using incorrect settings or whatever the case might be. Thank you.
On my Flickr page for each of these pictures I notated what was obviously wrong to me so look for that. You will need to view the pics in full screen to really see.
