This is likely Canon’s lens roadmap for 2020

[Pape]

sunny 16 rule:

ISO 100, 1/100s, f/16 or ISO 100, 1/200, f/11, or ISO 600, 1/1200s, f/11, or ISO1000, 1/2000s, f/11 its DO as well. for Daylight Only?

RF 70-200 f2,8 can handle dim light situations good enough. Idea of interchangeable lens camera is you change lenses for different situation.

I wonder if the extenders will work with the f/11 lenses !

 

[Mark3794]

I found the patents for this tele lenses, they are really simple design so hopefully really cheap and small.

f/11? Best be tiny lenses

Interesting (bit slow) Canon and what price ?, e.g, £2000, etc.

This lens 'Canon RF 70-200mm f/4L IS USM ' is the most exciting, hopefully Nikon will do a like for like version.

not my cuppa tea, although I would see myself replacing the 100-400 II if the new 100-500 is a better performer in terms of focus and IQ. If not, happy to carry a few converters on my wildlife trip for the 100-400 and 500 f/4.

Would love to see a 500 5.6 like Nikon

It's a "rule" from the film age though, right? If you are okay with leaving some quality on the table, bending it a bit should be fine with modern sensors.

RF 70-200 f2,8 can handle dim light situations good enough. Idea of interchangeable lens camera is you change lenses for different situation.

Of you crop the RF 70-200mm 2.8 to match the FoV of the 800mm 11 you're actually getting the same amount of noise, but with far less detail since that crop is so heavy, you're left with almost no pixels.

Interesting that they use STM motors, maybe they are going to be fairly affordable for their respective focal lengths.

 

[Gazwas]

Well, every extension of the RF setup is welcome! Personally I would really like to see new TS-E lenses like a new 17mm and finally the 35mm.
I know I have to wait...............wait...............wait...........

YES PLEASE!!!!

But I imagine these are years away (or never) considering the current economic situation and falling camera sales.

Damn 800mm and 600mm non L lenses? and DO? that does sound amazing. F11 is pretty dark though...

Wow, these guys should be incredibly light weight! At least from that drawing they look basically empty

370 mm length sticking out from the mount is also pretty decent for an 800mm lens. And 310 for the 600mm.

 

[bergstrom]

what the hell do you do with a Canon RF 800mm f/11 ? Definitely not for nighttime shooting.

 

[blackcoffee17]

No love for the m mount

This is why i'm hesitating buying an M6. It's quite expensive for a system with a questionable future.

 

[Antono Refa]

I expected Canon to make 500mm & 600mm f/5.6 DO to compete with Nikon's primes. I half expected 600mm f/6.7.

Do customers really prefer those two f/11 primes over a combo of 400mm f/5.6 + 1.4x TC + 2x TC? The 1.4x TC is supposedly on the way, is Canon going to skip over either the 400mm f/5.6 prime or 2x TC?

This is just what we now know is probably coming from a Nokishita Post. It doesn't mean nothing else will come out and we had rumors that the M system will get some attention this year. It may be that the current situation has pushed that back a bit into next year.

I wouldn't be so gloomy. I think if Canon feels like going to f/11 is okay in order to keep size in check, that's basically them hinting that reducing the image Circle to do RF APS-C isn't going to happen.

 

[SteB1]

Interesting. But a DO 500mm f5.6 would be far more useful. With a 1.4X converter it would be a 700mm f8 and a 1000mm f11 with a 2x extender. f5.6 is far more usable in a situation where you need high shutter speeds.

 

[scyrene]

F11? It seems really........wierd. is it perhaps a comment on the performance of the new sensors? I mean. Even if the AF can work at f11 you would basically NEVER have enough light to shoot at f11 at that focal length. At least not for wildlife. Unless the new sensors are a major step above what we are used to.

Here we go again! And once again I have to state: I've done a TONNE of wildlife shooting with the 500L+2x extender stopped down to f/10. Close enough to be relevant to an 800 f/11 lens. And this on aged Canon sensors! Mostly small birds and certainly not always in good light. People need to stop accepting received wisdom and open their minds a little.

*However* it does seem odd that the two extenders still appear to be orphaned. Even I would doubt a combination of 1600mm f/22 (although I did used to stack extenders and shoot handheld at 1400mm f/11).

what the hell do you do with a Canon RF 800mm f/11 ? Definitely not for nighttime shooting.

Erm... what would you be shooting at night at 800mm anyway? Well there's the moon of course, in which case this lens would be ideal.

 

[scyrene]

I do find it a little tiresome that given one of the most vocal groups here for several years has been the 'Canon needs to release affordable lenses over 400mm', now they have started addressing* that gap in the lineup, it's all 'this is unusable, why are they doing this'. Bright, long and cheap - you can't have all three.

*we don't know the prices yet but surely they will be much cheaper than the current supertele options.

 

[cazza132]

F11 - could be a Cassegrain style mirror lens with primary and secondary mirror elements. This greatly reduces the lens length to possibly 150mm long.

I am not suggesting it is impossible to shoot at 600 f11. Jut that it is VERY VERY limiting when that is the best you have to work with.

Yeah. Gotcha. So when you need F5.6 at 800mm you change the lens. Oh, wait...
Did you notice 800mm focal length Not 200? Good!
