Originally posted by Marc Sabatella Well, sure, you need faster than f/5.6. But I wouldn't think of f/1.4 as the ideal for pictures like the above. DOF is so thin as to be almost unusable. f/2 - f/2.8 tends to be the sweet spot. f/1.4 is more for cases where you specifically *want* very shallow DOF.
Also, relevant for portraits, AF isn't very reliable for portraits at f/1,4, either, because there is no easy way to control whether focus is on the eye or the nose (both would normally be in range of the same focus sensor).
Thanks for the information. I think I just need to do some practice and reading. I usually do portraits at the 2-2.8 range. and I thought it rather silly to buy a 1.4 lens, and always have to use it at 2.8... why not just use my 17-50 2.8 then.
Example. Here is a picture I took of friends.
K7 - FA50 1.4 Metz 50
50mm F2 1/180 w/flash
To me, this is no where near tack sharp, nor is the bokeh what it seems it should be for f2.
In all honesty. It has to be something Im doing. Please clue me in a little
