24-240 / 24-105 7.1 / 24mm IS comparison
7

Quick comparison of the 24-105 4-7.1, 24-240 and an EF 24mm f2.8 IS prime all at 24mm. Wanted to see if the 24-105 is as bad at 24mm as they say.

The centers are all pretty close. Close enough I didn't bother showing the crops. Nothing really to see. All are great in the center.

The edges, there was quite a difference. 24-105 is pretty bad, even at f8. The 24-240 gets quite good at f8. Prime still wins, as it should. I didn't show it, but the 24mm prime is better at f2.8 edges than 24-105 is at f8.  (Easiest to see the differences in the fire hydrant)

Surprised the 24-240 is so much better given it need much more distortion/vignetting correction than the 24-105 and it has more than double the range.

I've not noticed such a large disparity between 24-105 and 24-240 except at the wide and. 24-105 is very good from 35-105. But certainly can't recommend it for WA landscapes.

100% crops at f4 and f8 of just the top right edge/corner (view full screen).  Shot JPEG with in camera corrections.
