There are a few bad reviews of this lens and I've read most of them. I bought it anyway. I used to have a Canon FD 20mm for my old Canon A-1. It wasn't an f2.8 zoom. Extremely sharp and no distortion unless you want to add something to the image. I've sold it every 20 years after buying it for about the same price. Now about this lens: In my opinion it's almost as good as Canon. Yes, there's no resolution cap, but considering this is a zoom versus a dedicated 10mm, I don't mind. If you don't want to shoot at the widest (wide open) aperture (and not at the ultra wide angle point where you need depth of field) the lens works well. The auto focus is fast enough. I don't know why they complain about it. You will not take moving pictures with this lens anyway. This applies to landscapes and unusual angles when you have time to compose and move the object/point of view. Trees, rocks, old cars, buildings, etc. I mostly use it in aperture priority, stopping down to around F16 and adjusting the ISO to get a decent shutter speed when not using a coaster. I'm pretty good at 1/30, but I wouldn't recommend anything less than 1/60 with no assist. One review stated that the optimal aperture is f8. Someone tell me what that means. How can f8 be better than f16 or f22 for depth or sharpness when you can control the speed/ISO? Why not 5 stars. Well it would be nice to have a depth of field scale and secondly my camera doesn't have a still mode so I really can't see the full depth of field. Have fun with this lens. I don't think I'm filming this with a camera.
