Disappointed with my 24-70 II.

Acquired my new lens on Thursday.

I have been shooting it back to back with my 24-105 (purchased in Feb. of 2012) and I just don't see a real difference.

Perhaps slightly sharper and slightly better contrast but nothing that would put a big smile on your face. Nothing that changes my overall impression or enjoyment of the image.

Perhaps I have a bad copy of the 24-70 or an exceptionally good copy of the 24-105 (or some combination therein).

I will go out again but I know that I have already decided to return it.

A nice lens but the extra stop is not worth the loss of range and IS (not to mention $2,300 when a good filter is included).

Disappointed as I was really looking forward to using it and enjoying an appreciable jump in IQ.

PS - All images viewed on a calibrated Eizo ColorEdge.
