I’m in a little dilemma choosing a wide-angle lens for my Nikon D40x. Specs, price and build quality are pointing me to the Tokina ATX124 which is slightly cheaper than the Sigma 10-20mm. What’s causing the indecision is the fact that the Tokina does not auto-focus on the D40x while the Sigma does.
Not having used a lens this wide previously, I don’t know if auto-focus is a necessity for architecture and landscapes that I would be shooting mostly.
Do you have a thought on this?
