You all might be missing the real opportunity here: 800mm f/11 + RF-S speed booster on an RF-S body. Ratchet that image circle down to 1.6 crop, and you now have an effective 1120mm f/8. In fact, that might be the primary reason those f/11 lenses exist.
I already wrote it down, you can't attach it to a mirrorless lens, which uses all the available space for its optics, only SLR lenses which need a separate adapter, this EF to RF adapter can be exchanged for the Speed Booster adapter.And idea if this would this be an EF to RF or an RF to RF speedbooster? I guess I can see it either way...
I believe the APS-C speedbooster one is the idea I threw out a few days ago. If they're using the reduction in image circle down to the APS-C size, then you'd have a 1120mm f/8 on crop. If, on the other hand, it was a straight speed booster on full frame, you'd have a 560mm f/8 on full frame. Did I do that right?
There may be a higher-end APS-C mirrorless announced in late 2020, early 2021 [CR2]
I actually want 45mp on a crop camera. Why? The 'extra reach' of the crop?www.canonrumors.com
That means we can use Sumires in beautiful 8K. Haha. In the mean time, I'll stick to my MTF adapter.
with AF & at least tilt would work fine with FF lenses on FF sensors.how about a TS-E adapter ?
damn... what a BIG BRAIN MOVE FOR SURE if its real .A speedbooster from FF to APS-C/Super35 would have at least the following uses:
- 4K with EOS R without crop
- 4K in R5 crop mode to reduce heat output
- Adapt EF to a hypothetical Super35 RF mount video-oriented body
- Adapt EF to a hypothetical APS-C RF mount body
- Shoot more manageable-sized stills with future high-res R body in crop mode
I'm more interested int why the R5 and R6 don't ship with at least the basic RF adapter. People have been waiting years for these cameras, and the price is a steep premium... The outlay for the R5 and even two RF lenses is over $5000. You can't include the $100 basic adapter? I feel like if the original R came with one, these should as well.
What about FD to RF adapter? That might be very useful for many people who still ahve FD glass?
Hi,
I would, love the efm 22 and 28 macro will be amazing with RP focus stackingIf Canon could figure out a way to adapt M-series lenses to the RF and visa versa with backfocus correction optics, I would gladly pay handsomely for one...too bad I don't think anyone else would. Haha
Non-video guy here, but I have a question:
If this rumor is true, and that a cinema to RF adapter is being offered, does that mean:
a) A cine line of RF lenses is never happening?b) Canon will not make an RF cine body?c) Canon is just being wise and maximizing the RF platform's appeal to sell more R mount bodies?d) Canon just wants to sell more PL lenses and this is a way to do it?e) Canon would rather monetize mount conversion into a product (adaptor) rather than a service (an actual physical mount conversion)?
I don't know if such adaptors were expected or a very big piece of news. Which is it, and why?
- A
Maybe it's not a matter of "we can't make a EF to EF-M speedbooster" but a matter of "we won't make a EF to EF-M speedbooster"And still Canon can't make a EF to EF-M speedbooster.
Also it could be compatible with the RED Komodo, which is a S35 camera.A speedbooster from FF to APS-C/Super35 would have at least the following uses:
- 4K with EOS R without crop
- 4K in R5 crop mode to reduce heat output
- Adapt EF to a hypothetical Super35 RF mount video-oriented body
- Adapt EF to a hypothetical APS-C RF mount body
- Shoot more manageable-sized stills with future high-res R body in crop mode
