A Distorted View on Things
One of our members over at The Photowalk Alliance was in the market for a new lens to do some portrait work. Fellow TPA Co-Founder, Joe Sterne mentioned that she should be careful about lens distortion, especially if she was using specific camera sensors, or had limited space. Come to find out, she was going to be shooting in a very tight space, and had considered using a wide angle lens to do her work.
I wanted to throw something together quickly just to show the differences between wide angle lenses and the "nifty fifty" when used on both a full frame sensor (Canon 5D mkii) and a crop sensor (Canon 7D). All shots are OOC, and taken from about three feet away. The 50mm lens is the Canon "Nifty Fifty" and the wide angle lens is the Sigma 10-20mm f/4-5.6 EX DC HSM Lens. It's also important to note that the 50mm is a EF lens, and the Sigma is their equivalent to a EF-S Canon lens. That's the reason behind the black circle on the 5D photos.
The differences are pretty mind-blowing.
