Longwood 2007-03-18 - Elegance_4933.jpg
This is the ceiling of the organ room at the Longwood conservatory.
Yes, the straight lines do betray some lens distortion (the ceiling is flat), but then this is just my "cheap" $400 consumer-grade 28-135mm lens. I've been debating whether to spring for the 24-105mm "L" lens to replace this. Of course, I'd be really PO'ed if I got this same effect after spending THAT kind of money.

JD Canon 10D EXIF Data Included Additional images at; http://www.flickr.com/photos/john-pa/ You took this with the lens set at or closer to the wide angle focal length (28mm), right? The distortion is the effect of the wide angle, and won't go away with a more expensive lens. Actually, there is always some distortion of straight lines, but at longer focal lengths it is so small that it's hard if not impossible to see. Art the other end, (135mm) you will get fore-shortening, and shallow depth of field. You can't win. :-) But you can take advantage of the effects produced by different focal lengths. Play around with the lens - take the same subject at different focal lengths, and at different distances to the subject. You'll find that a telephoto closeup will have a different effect than the wide angle one, for example. You'll soon be able to decide in advance what kind of effect you want.

I thought that this might be a wide-angle effect too, but my Canon 10D
has a 1.6x Field Of View Crop, so this 28mm is pretty much "normal" on my camera. I wouldn't expect to see the wide-angle distortion in this event ... or would I?

It's lovely; I particularly like the etched/frosted - whatever it is - translucent glass of the rays near the center.

The crop would minimise the apparent distortion by removing the areas (near the edges) where the distortion is most severe. HTH |

Hmm.. yes, as I think about it, it makes sense. OK, so instead of a
$1500 lens, I really need a $3000 full-frame camera. I'll tell my wife it's all your fault.
