Is the RF 24-50mm a serious threat for crop RF camera's?

Judging by the dpreview samples, the RF 24-50 is absolutely worthless, I'd rather buy a cheaper body and some better lenses. What's the point of using a fullframe body with a cr@p lens?

Do this: open the jpeg link on image 23 in the R8 sample gallery

This lens is not super high res, but it is far from horrible. Seems to me the problem with this lens is that it is slooow, which I'd guess explains the variability in the sample gallery image quality.

We all know it's not impossible these days to make a cheap mid focal length lens that is pretty darn good optically. This lens appears to fall into that category. It's plastic, has a plastic mount, it's cheap. Optically it appears to be pretty good, but perhaps inconsistent because because it is slow.

To me the jury is still out. Put it on a tripod in a studio with strobes and see what it does. Or outdoors in axis light on a tripod. And if you don't get that quality in random handheld perhaps the blame is not the optics, its the slow max aperture.

It's all about shutter speeds and stabilization. You can see the shutter speeds of the dpreview samples. Can't be the problem for all pictures imo.

You only need to see one good image to know optics are not horrible.

The average of all images may not be good, if so, and if you already know optics are not horrible, the problem is not optics. With a slow lens, handheld, you're shooting a larger

aperture with shallower

not shallower, deeper

DOF and higher

probability of slight misfocus. And you're shooting longer shutter speeds

A slow lens doesn't cause longer shutter speeds, as you can simply use auto ISO eventually combined with a minimum shutter speed.

which means slight movement of subject or camera is more likely.

It's just about the shutter speeds, and these are shown with the samples provided.

at longer shutter speeds.

You are right, I wasn't clear, I meant larger aperture relative to the end stops on that specific lens. Lenses are generally sharpest 2-3 stops down (but not expensive apos), and that very probably applies to this lens too.

Yep auto ISO, but I saw a lot of shots that were are 1/30 1/60.  There isn't much cushion there with handheld.

And if the optics are good in ideal conditions they are good, variations from "best" level have to be attributed to other factors.
