| p.4 #8 · Canon EF 24-70mm f/4L IS Resolution Tests! |
I will try to do some f/5.6 testing next week. The rest of today, as is traditional, is being spent taking one of the new lenses apart
(Yes, of course, pictures are being taken)
anyway 5.6 is good but any chance for f/8 too, since landscape people really do care about that, even if just at 24mm (and I know their are fast prime shooters who just go on about how everything is the same at f/8 and who needs a fast prime when any old zoom works for landscape but comparing, say, 28-135 IS to 24-70 I/24 2.8/24-105 to 24 1.4 II/24 T&S/24-70 II that really is not true at all and all too often IMO, wide open or near wide open is the only thing ever discussed). I know it a TON of work though, it's easy to ask and tough to test. Personally I'd rather see f/8 than f/5.6 if it had to be one or the other.
(although f/8 real world usage can become tricky since field curvature can come into play as much as anything else too)
