RF 24-105 f/2.8

[Kayaker72]

For IQ, Bryan has now posted his IQ tests. I have mostly compared it to the EF 24-70 II. I'll go back to the phrase, I think this are far more similar than there are different. If you stare (and I did), I thought some of the EF 24-70 II had an ever so slight advantage and others where the RF 24-105 f/2.8 had a slight advantage.

Video. I did a quick test video. I could not hear the lens at all during the video. Absolutely silent. I can near hear myself breathing, so the next thing for me to work on.

As for Image stabilization at 24 mm. I walked onto my front steps at sunrise this morning just before sunrise. All three images at 1 second were sharp. There is 1 of 2 at 2 second and 1 of 3 at 4 seconds that I would use. Not as sharp at 1 second. So....a hand held, un-braced, 4 second exposure and I have a usable image.

Not trying to win any competitions here, but un-edited ~100% crops from the 45 MP on the R5 before sunrise shots in New Hampshire (overall scene was metered to be 2/3 stop underexposed, but AF was on this house and it has most detail, thus the crop of it).

~100% crop handheld at 24 mm, 1 second, f/8, ISO 100:

~100% crop handheld at 24 mm 4 sec, f/16, ISO 100

Is this replacing my EF 24-70 II for all purposes, no. The size, weight, and ergonomics are different enough.
It this replacing my EF 24-70 II for several purposes? Yes, and the list is growing.
