Barrel Distortion, IIRC... If not, then I R noob.

Yeah, now I think I'm gonna shift my focus from picking up the 70-200 F/4L to picking up a nice quality used 50D..

Hey CG (et al) -- question for you.



This is off the EF-S 17-85 I just got @ ~38mm. Besides resizing, completely untouched (by me at least, SmugMug might have massacred it, but it doesn't change the fact that I'm seeing what I think I'm seeing).

Take a close look at the bottom left -- is it just me, or are the steps closest to me appearing as though they're not straight (as in not forming a 90 degree angle) -- I'm going out to try to take a closer look at it with the naked eye, but I dont think they normally look like that.

I thought this could be somewhat of an issue similar to barrel distortion, but @38mm that seems drastic. Also, the rest of the photo's perspective seems alright. Hm.

That's perspective distortion, which is common with wide angles, though at 38mm it's surprising to see (flaw of the lens).

i see that a lot on my 12-24 but thats kind of suprising to see it at 38mm.. lots of factors come into play, it might not be straight to begin in, u werent straight when u took picture, lens, etc

The 17-85 is basically the aps-c version of the 28-135, which is a full-format lens. In this case, wider is better.

Distortion is TRIVIAL to correct, use Digital Photo Pro to do it.

PS: I just got rid of my EFs 17-55mm f/2.8 IS and replaced it with an EFs 18-55mm f/3.5-5.6 IS lens am I crazy?

Extremely crazy! Desperation sale?

And distortion is fairly easy to correct, but it's destructive (i.e., need to crop), which is why I always allow some extra space in the frame when shooting at very wide angles.

No, moved up to full frame but wanted to keep the aps-c as a grab 'n' go dSLR. It's actually a very good lens.

Yeah, distortion correction is destructive it also makes pictures a tad softer but a non-distorted picture is higher on the list than sharpness.

Yeah, I just got out of a training and there happened to be some pro photogs there. They agreed with PD but said it an be encountered semi-frequently up to about 50mm, so I felt a bit better about the lens. I'm going to do some shooting this weekend and will bring my old powershot for comparisons to see if there's a defect with the lens or not.
