Here are all of my images of various subjects with the lens. It's a keeper and I also like to use it with film.

F17-28 - a set on Flickr

OTOH, if you want a cheaper wide angle lens, you might consider the Tokina 19-35 lens. It's not fisheye and gives very nice results.

It's usable on APS-C too any quite creative to use. You can really play with perspective.
It's great of tree shots!

Portraiture is good from 20-28mm





And I've used it for sports too!

thank you, guys, my problem is, that i now have A28/2,8 and ii is great, but not wide enought. my first choice was sigma 10-20, but it is too big and then i am looking for da15... (for size and extremly good performance in direct light--- stars.. oh...). few days ago i saw this fish eye for circa 250$ and i was thinking, that if i can perfectly correct fish-eye barrel effect, that will by great for me... i dont know, what do you think? guys?? )

I see no reason for this lens if you don't want to play with the distortion. You will just lose image quality and cut away large parts of the image. Why not get the 18-55 instead in that case? If you get this lens I recommend you to work with the lens characteristics instead against it, it's named fisheye for a reason. There are loads of people shooting landscapes with fisheyes without correcting the distortion.

The 17-28 is a full frame (24 x 36 mm) lens so the fish-eye effect is not terribly pronounced on an APS-C sensor camera. You may often not have to do any correctlion at all. Here are some samples I took way back when which illustrates the coverage.

I have and shoot with this lens on both film and APS-C , On film its wonderful, on the digital the crop does reduce back its "wideangleness". I found from comparison, it takes in the same angle of view on digital as my 12-24 sigma rectilinear wide angle. I did pics with both with the camera on a tripod to compare before I went to Cambodia in 2009, as I was trying to "Pack Lite". Because the 17-28 had the same field of view as the 12mm I took it, but have regretted that decision as to de-fish the sheer number of photos I wanted to ... It just wasn't worth the time and hassle of all the PS work it in my opinion for me, when a rectilinear lens will give you exactly what you want straight out of the camera. I still use and love this lens, for the image it produces as its still a stellar little lens.

This is a really interesting lens that was unique to Pentax when it came out (fisheye zoom). It's sharp, very flare resistant and light. After comparing it and using side by side with a Zenitar 16mm, I returned the FE17-28 mostly due to usage preference and design/built quality. For me the IQ of the two was close (but the Z flares badly in comparison). I found that I could not trust the AF with this lens (K20D) - on critical inspection, the focus would often be slightly off. Switching to MF solved that except that the focus feel is non-existent, and just moving the camera around you could throw the focus off .. infinity was the kicker though, you'd probably have to tape it to set it there. If I remember it focuses just past infinity, so real world use swayed me over to the Zenitar, even if it "wobbles" slightly, it still produces consistently good & sharp results. (Anybody have a link for DIY Zenitar "tuneup" ?)

In retrospect I should have kept it and may have well doubled my money$ on resale .. lol c'est la vie!

F16 is in the diffraction zone so you will lose peak sharpness no matter the lens.

The lens starts to loose peak sharpness at F11: Pentax SMC DA 18-55mm f/3.5-5.6 AL WR - Lab Test / Review - Analysis
So do the 15mm: Pentax SMC-DA 15mm f/4 AL ED Limited - Review / Test Report - Analysis
