Thanks Gianfranco
Now I understand. (Mostly.) And MTF sounds like a fairly useful feature...
But when you say the PZ1p's MTF mode set-up never selected f1.4 on your F1.4
lens, (I guess because it considered f2 to be the sharper setting), couldn't
that sometimes create problems?
As when you're shooting, hand held, without a tripod, in very dim light that
would require say, f1.4 at 1/30 to be successful, while f2 at 1/15 would be
very risky, and f2 at 1/8 would certainly not do?
(Perhaps, in your own preferred style of shooting, you've never run into
this problem?)
Do you think your PZ1p would NEVER select f1.4 in its MTF mode?
And also, does it ever select f1.7 or f1.8?
Perhaps it is me who is misunderstanding something here....?
Thanks,
Skip
