Define "extreme" fisheye. As in not a round image?

If you're looking at rectilinear fisheye lenses, but don't want the normal distortion you might consider the Zenitar 16mm. It's fishy, but not overly so. I sold mine and picked up the DA 10-17 for that reason.

Depends on what your expectations are as to what you end up getting.

I don't see a lot of pf with my 10-17, except in extreme situations, like a lot of lenses. If you have a K-x or K-7 you can set the camera to correct for CA.

Gotta love the 10-17's 1:2 close focus and saturated Pentax colour rendition.

$700 for the K 17/4 sounds high. Even for an A 16/2.8, and that is a darn nice lens if you can find one. The DA 10-17 is a more practical choice, probably, unless you highly value compactness. As I do. Zenitar 16/2.8 is supposed to be good as well, probably just what you are looking for.

I have had mine for about 5 years and have taken some pretty nice images with it. Its the most versatile fisheye you can have. Purple fringing has not been a problem, and if encountered, software can fix it.

I know of no other fisheye that can provide the service this one provides....

Here is an example - click on the image twice and it will enlarge. This is just from a K100, 6MP. Great detail. Plus this is directly into the sun - no flare, no PF. The only down side is that it can not take filters.

The Pentax DA 10-17mm f/3.5-4.5 definitely get my vote if you ask me. PF is quite frequent when I use it on indoor shots with white lighting or nighttime shots with lots of bright lights. In outdoor use in daytime shooting, I don't see PF showing as much. Here are samples with K20D and the DA 10-17mm, please noted the PF in most of the white lights in the baseball field.



1/30 sec, f/4.5, 17mm, iso 800, 0 Ev


1/30 sec, f/4.5, 11mm, iso 800, 0 Ev



0.8 sec, f/4.5, 17mm, iso 160, -0.3 Ev, hand-held shot


Pentax DA 10-17mm f/3.5-4.5

With the DA zoom, you have the choice of getting the extreme fisheye subject in the widest end as in 10-13 while I can have the least fishy to almost like a normal wide angle in the 15-17mm end. It is one of those fun lens that I love having in my bag.

I think he means full 180 on APS-C. The Zen only gives about 120 degrees diagonal on my K10D. While the Zenitar is not particularly "fishy" on APS-C, it is by no means rectilinear...fisheyes never are. They all use some form of circular projection.

thanks for all of your input.
I hadn't seriously considered the zenitar 16mm maybe I will give that another look.
and by "extreme" i meant no more than 10mm.

I said they're not mine--see above.

Guess I shouldn't have just said "some guy" in the Tak Club.

Sorry!

Yep, a few posts later (as I see now). It would however be nice if you gave the credits in the post that contained the photos.

I didn't have any intention to pass them off as mine, and I should have credited it from the first post.

I'm just so blown away by those shots that I wasn't thinking.

I know, but it can be misinterpreted
