Lens Tests

I thought I'd familiarise myself with lenses more so I took some out and had a play. I took out a 10-22mm lens and had a look at what it looks like at 10mm, 12mm, 14mm, 17mm, 20mm and 22mm and compared depths of field between 10mm, 17mm, and 22mm. I also took out a 180mm lens to compare how that looks against the 6 wide lenses. I didn't take anything in the middle (50mm) as that is too close to normal vision and I felt that for now, learning the difference between wide and long lenses would be sufficient.
