Lenses on Crop Sensor Cameras and Distortions

Confused yet?

There's good info here already. Just a couple of thoughts.

Two kinds of "distortion"

There's barrel and pincushion distortion, where the picture is stretched out in the middle of the four sides, or squished in.

This is what makes people at the edges of wide angle frames look are weird.

And there's compression distortion. This is what makes noses look big up close with a wide angle lens, or telephone poles look close together when shot with a telephoto lens.

This second kind is what matters most to you, I gather.

For low budget, the suggestion you use your kit lens at 55mm is a good idea. I do this all the time.

If you had a 18-135, or a 55- 250, you could zoom to 60-70mm for the ideal perspective.

Sigma make a 70mm lens; Canon makes a 60mm lens, as does Tamron. Any 24-70 would be a good choice, but these are either expensive or really expensive.
