blue lines are f8 right?
yes its better but its a pretty small margin (not that there is much margin anyway)
black lines are wide open and you cant really compare them since there are 2 stops of difference
how can you compare f1.4 vs f 2.8?
I dunno but I prefer to judge based on images rather than numbers and lines
for example looking at the 35mm ziess f1.4 and the canon 35L f1.4 the ziess looks better IQ wise on paper
however once seeing images the bokeh was a deal breaker for me the samples of the L we significantly more pleasing to me.
There is far too much importance being placed on numbers and charts over actual images these days
since the 35mm is closer in focal length would it not be better to compare vs that?
still looks sharper in the corners stopped down
how about vs the 16-35 f2.8L II? shown below
this is the tele end charthttp://www.usa.canon.com/cusa/consumer/products/cameras/ef_lens_lineup/ef_16_35mm_f_2_8l_ii_usm
looks quite a bit sharper actually
BTW I'm not disputing the lens looks good from the MTF just that its not really comparing apples with apples
I might look at using it as a functional body cap too
I cant wait to see some sample images from early adopters
