Fisheye 10-17 question

2007-01-05 Thread Gonz
I've seen some nice pics from this lens. W. Hamler's recent Hot Dog Heaven is a prime, err... zoom example. My question is related to its fishiness. I've heard that the lens is a fisheye at 10mm, but loses its fishiness as you head towards 17mm, so that it looks like a rectilinear at 17mm.

By 17mm the distortion is pretty much non-existent. Here are a couple of examples of mine (taken in the exact same position): 10mm http://www.arach.net.au/~savage/Misc/Images/IMGP5146_1.jpg 17mm http://www.arach.net.au/~savage/Misc/Images/IMGP5149.jpg HTH Dave On 1/6/07, Gonz [EMAIL

Well, I disagree with Dave. The lens is still quite fishy at 17mm, and if you look at the curvature in the buildings, trees, and road in the second pic, you can see it easily. It's a great lens. I enjoyed the 17-28 so much on my (P)Z-1p that I asked for the 10-17 for my birthday, and got it.

I can see a slight amount in the tree building but none in the road. I think I picked a bad example. I've just gone and searched through my archive for another shot at 17mm and it displays obvious fishiness. So I'm withdrawing my pretty much non-existent comment. Funnily enough almost all the

Thanks Dave. I dont see much distortion at 17mm, but its hard to tell since there are not many lines to allow a clear conclusion. rg [EMAIL PROTECTED] wrote: By 17mm the distortion is pretty much non-existent. Here are a couple of examples of mine (taken in the exact same position):

I got the lens for a specific project that ended up not happening. (360 degree QT VR panos of a ship's interior). Cheers, Dave On 1/6/07, Gonz [EMAIL PROTECTED] wrote: Makes you wish you had that prototype 8mm fisheye that never made it to market huh? rg -- PDML Pentax-Discuss Mail List
