Originally posted by UncleVanya Can you crop the 18-135 effectively to compete with the 18-270 on the k3?
How do the two lenses compare in the 18-135 range - does anyone know?
No, I wouldn't try cropping that much. I have never used the 18-270, but my impression from what I have read is that they are about the same in the 18-135 range. Which means that the 18-270 will probably be a better travel lens (except for the lack of WR
and quiet focusing [oops, didn't know the 18-270 had SDM]).
My copy of the 18-135 seem to better than many at the long end, but is not the best at 18-20 mm. I have seen claims that this lens is "useless" above 100 mm(or even 70!), however that is not my experience at all. It does indeed indicate too much variation in quality, though! I don't know if the 18-270 suffers from the same variable QC.
