10-17 Fisheye AND another wide angle?

So, I have the fisheye lens, which I love. But debating on if I want another, non-fisheye lens to complement it or not.

Anyone running with a 10-17 (or similar fisheye) and another super wide angle option in the same kit (10-20, 12-24 etc)

I know I could de-fisheye after the fact, but I don't like the idea of doing that honestly.

i paired mine with a da* 16-50. it doesn't make much sense to me to carry 4+ lenses when i could get the same coverage with 3 (10-135 or 200 depending on telephoto in my bag).

Neither would be needed-I have a 16-45 pentax for the wider range. I was specifically wondering if folks had a super wide in fisheye and in rectilinear, or just stuck with one or the other

well if you're just accumulating why not get the 10-20? it's not bad. it'll have a different look to it.

I think someone already did this test, and posted the results, but the question is not so much running both, but if you need a rectalinear image, what is the cropped central field of view of the 10-17mm fisheye?

I think you will find that once corrected you are at about 14mm but please someone do the comparison, I am going here on memory and suffer from CRS.

If you need true rectalinear images with a 10mm field of view, I would add the sigma, and not the pentax 12-24, only because it may not offer enough additional width, compared to the corrected image from the 10-17 fisheye

I do net remember the OP. It was in my bookmarks.

At the end I chose 12-24 among three.

might be nice if someone could do that compare you speak of. i hope to spend tuesday just playing with the gear, so maybe that will help me out too.

haven't tried the cropping or anything like that. most of this is just curiousity

I got the 12-24 first because I really needed a wide angle for my travel shots, the 18+50 zoom I had was nowhere near wide eanough for many of the large buildnings and structures I photographed. Later I added the fisheye because it looked like a fun lens and also to have something else to fall back on if the 12mm was not wide eanough, they complement each other in that the 12mm covers 99 degrees and the 10-17 covers 180-100 degrees. and I am much more of a wide angle shooter, I rarely go over 100mm so I decided it was more important to invest in the wide angle than to get lots of long primes.

maybe the da 14 could be an alternative too, its not as wide as the fish, neither is the 12-24, but it does have extra speed that the fish doesnt have.

The guy over at PhotoZone always does a constant job with lens reviews and puts in a few example shots. The 10-17mm review as some examples of "corrected" photo. There are similar treatments for the Pentax 12-24mm and the Sigma 10-20mm. . For myself I have the 10-17mm and will eventually get the Sigma 10-20mm. They give a shot a very different feel and correction is never perfect.

Unfortunately it only shows 15mm fish eye but you get the idea

That might be me :-) This is a damn confusing thread as the first few replies made no sense to me...

Here's the 10-17 vs 12-24 side-by-side. I actually did this to see if the "same" focal length was indeed "different".

the question is, if you take a shot from each in 1 mm increments of focal length, then, using the correction factors pentax gives for the 10-17 to correct the istortion, what does the rectangular crop out of the middle of the 10-17 shots look like, and if shot from the same distance as the 12-24, how do they compare?
