Canon EF-S 10-22mm or Sigma 8-16mm

[413x]

 

[D.P.]

Impressively wide

I don't think I will be doing that wide much (if at all)

I have quite a good returns window with JL so I'm wondering if I should get the tok as well and return one? But I am not sure what I will be doing except for night shots for a while

How much width does 1mm make in real terms?

1mm at these wide angles does make a noticible difference. Have a look at the field of view angles

 

[413x]

Ah yes i saw those. Quite dramatic how 400mm is a slither and the ultra wides get not so far off 180!

EDIT: i cant seem to find the useful graphic displaying this!
it was an interactive semicircle, just nice for visualising


EDIT 2: the cashback has already been confirmed!

8mm is very wide, so wide that you have to be careful not to photograph your own feet !!
