Hmm...what I meant was...if you were to say put the 24-70 @ f4 - 35mm and the 24-105 @ f4 - 35mm which would have a more pleasing bokeh...

I realize the DOF of the f2.8 is much less than the f4 lens...

thx, rob


I think the new one will have the edge as it has more diaphragm blades

A wide open lens doesn't show diaphragm blades though...
Does the new lens have the new fancy no blade diaphragm (forget what it's called)?

Taking into account a considerable sample variations of complex zooms, wider tolerance of AF lenses and real life conditions like flare, the charts are of limited help to me. They're most useful to a designer.
However, if your experience is different then mine, then I'm happy for you.


I agree in that MTF charts may be overoptimistic. My experiences tell that especially the charts of some IS lenses are definitely optimistic, because they should be sharper than their non-IS counterparts or older primes, but real life tests do not support that.

But in this case, at 24mm, the MTF chart already said that the quality will be low in FF corners.
