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

I think it's a pretty bad idea to mount such a slow yet big wide angle zoom as a standard zoom on a crop camera.

The RF mount is clearly designed for full frame, and to combine this mount with aps-c sensors are clearly an afterthought.

I ordered an FE 28-60mm for compactness sake by the way. I will consider it to be an f/8.0 lens for IQ reasons. But even stopped down that far it will do the same thing as a 17-38mm f/5 on a Canon crop sensor in a really small and light weight package. I think that's a better idea than a big slow 15-30mm on an M50, with no space at all for your fingers.

And the same logic applies to the RF24-50 on the R8 or RP.

I didn't see great IQ around f/8.0 yet from this 24-50mm lens.

It will be a great option as a daylight, walk-around kit.

I hope you're right, but I'm afraid it's more a budget option than a compact option.

Those MTFs tell me it performs better than the 24-240. So it’s a budget and compact option. Quality? There’s no L here. Price is right though, as is size.

Im pausing though at any of these options. Although formidable compact power (R8/R50), I dunno, something’s missing here. R50 has several corners cut that are annoying (no self cleaning, m50 buffer size and is still UHS-I). R8 although impressive lacks a compact telephoto option. Neither of these are M-killers even though they’re clearly supposed to be. The R50 and new 55-210 get pretty close though.

Re: Canon RF-S 55-210mm f/5-7.1 IS STM Lens (Canon RF)

hmm, f7.1 on a budget crop body where focus aquisition spec would be EV +1 + would have little chance of focusing long range indoors for those school events

whereas Canon RF 70-200 F4L @ F4 on R8 would have a whopping focus aquisition of -3.2 EV (4.2 + stops better) and will focus in full moonlight - and combine the facts that it is only pop can size and dxo PL6 will give it 1-2 stops better high iso performance - all makes the small R8 the clear choice for enthusiasts that progress beyond consumer stuff

Same argument holds if this was the EF-M 55-200. I had no problems with it in said conditions.

Im still pondering FF vs crop. Patent just came out of an RF-S 15-70 f/4… Sounds like Canon may be picking on Fujis lunch next. Interesting move as I consider the R8 a Fuji X competitor.

you've bailed out of m how many times?  5? 6? more?

the m system has already been killed for you so if you claim this or that is the killer, the m system is already dead based on your behavior to continually bail out of it

R8 is the fuji killer with both the focus system and the focus acquisition system

even sony cannot keep up with their EV at -1EV @f4 vs R8's -3.2 EV @ F4

my killer zoom is the pop can sized RF 24 -105 F4L with nano focus and EC on the control ring on an R8 body that gets R3 AF performance and gets -3.2 EV focus aquisition @f4 indoors and with dxo PL6 will provide an additional 1-2 stops of indoor performance

repeat after me:  focus aquisition and best in class NR for an f4 lens indoors
