One website tested the older EF 24-105 and got 50-55 lp/mm IIRC. So that's good enough, probably even to print large, but there are sharper lenses out there.
So I suspect there's more a difference of opinion on whether a lens is sharp or not, depending on what you compare it to and your definition of sharp than copy variations. It's kind of in that good enough but not great range. 50mm lenses generally get 63 lp/mm and up on the old tests, some lenses over 80lp/mm, and occasionally something is 90lp/mm.
But 24-105 v1 really quite large range, most of the larger ranges of the day only 28mm on the wide end. So the performance is reasonable.
The 24-70/4 should be pretty close to 2.8 v2 performance, I'd think. I'd have to think it might be damaged if there's a huge difference. ...Show more →
I have used most of the EF lenses back to the 28-70/2.8 and also the 24-105/4 RF. The main differences between overall opinions depend mostly on the three factors:
- Focal length where the lens is tested
- Aperture where the lens is tested
- Relative importance of the MTF and aberrations as a function of radial distance from the frame center
Some sites are interested in center to corner for landscapes at smallish apertures and others care about wide open humanoid portraits for example, and will have very different IQ evaluations of the same lens.
