[Brightcolours]

Well, no, there isn't a contradiction in practice, because I'm not switching to mirrorless, and even in the off chance that I did, I'd probably choose a system other than Canon RF. As it is, I'm not changing anything in my kit, and I'll keep enjoying the benefits the accumulated system (which, admittedly, is pretty patchy, a mishmash of different classes of gear) allows me. Of course eight lenses might be overkill but all of them are finding more or less frequent use, so I'm not quite ready to downsize either.

But still if the 24-105/4-7.1 is that decent, why does Klaus keep referring to it as coke bottle.

Because Klaus. Like I said before (I think), Klaus would not find the 24-85mm decent nowadays.

And patchy, my system is even more patchy. And I even use an EF 35-70mm f3.5-4.5 A at times, which can't even hope to reach the resolution and contrast your EF 24-85mm can reach (can't find MTF curves for that lens to illustrate). Just because I can, and it was too cheap to pass. And I'd even consider the RF 24-240mm lens as "standard zoom". 

My point kinda is: if you find that 24-85mm lens to be good enough on your APS-H, you will find that you can get good enough results with that RF 24-105mm f4-7.1 on RP, R or R6 or R3 too. Klaus' perspective is from a reviewer, but people can get good (enough) images with just about any modern lens (although there always are a few exceptions).

Sure, Klaus likes to stir the pot ("coke bottle"), but this is what the lens (24-105mm) does even at 24mm:

That image is more than usable.
