Samyang XP 10mm f/3.5 for Canon EF announced
#11
Inifinity is one thing, but how many times would one want to focus at infinity with an ultra wideangle? That'll probably just net a big "empty" shot with lots of small distant things. Smile

I find it too difficult to find precise focus in MF anyway (for example when focusing in a light so lousy that AF refuses to lock on) - I tend to rotate it back and forth for a long time, many times just missing the correct distance and getting to where things are softer again (not helped by the fact that it usually takes a tiny rotation of a focus ring to throw things far out of whack). When I'm using MF it's usually when I let the camera/lens AF once and then turn off AF to keep the focus distance put lest the setup starts trying to refocus, thus wasting time (for example, when shooting fireworks).

With these manual focus lenses the focus throw is usually much larger than with AF lenses. So, in theory you just could do a series of shots, i.e. focus bracketing, one shot should be ok.

Waiting now for the crop version of the lens...  6mm  ;-)
