Thanks for all the feed back guys. I did a little more research and checked out some lens tests. For the tamron and rokinon stuff I looked out how they performed and tested on the nikon d810 in dxo since that is from my understanding just about the same sony sensor that's in the k-1, and the closet thing that compares to the k-1 that the lenses have been tested on since I cant find any test results on the k-1. And I have no reason to believe that I would not get as good if not better results on the k-1 as they did on the d810. What I have decided to do is roll the dice and get a rokinon 14mm (and hope i don't have to return a bunch of copies until i get a good 1) for my uwa landscape and nightscape/astro since a good copy tests really good and it resolves enough of the 36 mp to leave some crop room. Then I am going to get as well the Sigma 35 art which will still work for my landscape uses, and I read it performs as a good astro lens as well, and it just makes for a really sharp, fast, walk around lens. And then I was looking at the pentax 50mm macro lens, I don't do a lot of macro but I like the option to be able, and from what I have read is that it is a very nice lens as far as performance for macro and just as a walk around 50, just lacking in build quality some. Then in the future look to invest in a prime in the 20-30mm range. I also read some of you guys mentioning the tamron 70-200mm vs the pentax for $1000 more. The only 1 I see listed on b&h is the tamron 70-200mm f2.8 DI LD (IF) MACRO AF LENS FOR PENTAX AF. I see that it has macro in the description, was this the same 1 you guys have referred to, or did they make a non "macro" 70-200 2.8?( i know that its only 1:2 macro at 200mm)
