Ouch ....

You found the RF 24-105mm f4 L pretty good for the type of lens, when you reviewed it.

When you compare the cheap new one with that lens' Canon MTF charts, there is not a huge difference, the corners at 105mm wide open at f7.1 better than the f4 L wide open most obviously, and looking at the OL review, it is the corners that got better with the f4 L when stopping down.

To me, it seems this lens is not that "ouch" after all, if we just look at these MTF charts?

Well, at 24mm the L is certainly better and at it's surely also better at 105mm at the same aperture.

Yes, both are true, but the difference is not huge. It would be "whoa" instead of "ouch" if this $400 would perform equally to the $1099 24-105mm f4 L, wouldn't it?

To me, these MTFs look really decent for the type of lens this is, am I reading them wrong?
