Dat's sum barrel distortion

[Mbnmac]

Been messing about with my D90 all week, mostly with my 35mm 1.8, but I found I needed a bit more wide angle, so threw on the 18-55 3.5-5.6, and wow did it make for some weird distortion wide open.

Both images below are with the same lens, you can see how much it straightened the chalice;

Not really looking for C&C, but if you got any throw it out there.

Totally makes me want to test it all out, and do the same with future lenses

Interesting!

What were the focal lengths & apertures?

 

[Destin]

It is mainly because you're closer to it and shooting up at it. It's more of an optical illusion than lens distortion

Your also shooting from a totally different angle/side

This isn't barrel distortion. This is perspective distortion (that's what I'm going to call it). Things closer to your eye look bigger than those far away. This is not to say that the 18-55 doesn't have any barrel distortion. If you weren't a member since 09 I'd think we were being trolled.

agreed.
you really cant compare the 2 shots.

I wasn't comparing the shots so much as showing the true angles of the chalice.
I've noticed the distortion on a bunch of photos, mainly architecture photos.

I know perspective has something to do with it, but to make those angles almost straight?

and don't base knowledge on length of time on here, I'm still very new to this.

Also, both were shot f8 and 18mm

Yes. Perspective can have that effect.

If you have better examples post them.
