Re: DA 16-45/4 is finally available

Joseph Tainter a �crit :

Alex, help with a little test, would you? Set the *ist D to mtf 
(custom function 1), then test it outside in program mode on a day 
with good light. What f-stops do you get at different focal lengths? I 
got the following, which seemed odd:

16-28 mm. f4.0

35 mm. f4.5

45 mm. f5.6

It is normal, MTF mode does not propose the fastest aperture, but that 
where optical quality remains good.
Chage custom fonction or use green program to avoid f/4 constant.
