News Flash: Good news for some, bad news for others

[Richard CN]

Nokishita has updated their information and included information on the mount. It does indeed appear that the RF mount is a shorter registration than the EF mount, and it requires an adapter to use EF lenses.
That is sure to please some that want to adapt lenses to the RF mount, and will disappoint others that were hoping for native EF compatibility as we surmised before.
From Nokishita;
M adapter R was confirmed with “Mount Adapter EF – EOS R”. Three types of mount adapters are available with control ring and drop-in filter.
The ability to use drop-in filters will certainly make this more than just your regular “dumb” adapter and add useful benefit to using EF lenses on an RF mount.

I don't think it would be a problem. And it still sounds like a 'sexy solution' especially for video but also for stills.

Stupid Canon

 

[dkangel]

Well crap.

 

[miketcool]

At least this solution cuts down on the nasty flares, vignetting, and ghosting that can come from filter usage.

 

[BeenThere]

This is the simple solution, but not my preferred solution.

Ugh. I thought Canon was gonna kill Sony with this release, but both Canon and Nikon are at a severe disadvantage now. Sony has 60+ native lenses for EF mount. Nikon has 2 or 3, and Canon will have... 5. Yikes.

NO ONE WANTS TO USE ADAPTERS.

 

[mppix]

To recap: to mount ef on rf, you need an adapter, ef to m, you need another, and for rf to m another yet. I sure hope, this is not the full picture..

 

[JBSF]

Well crap.

Agreed. Sort of. This does leave open the possibility of adapting legacy lenses. I hope the adapter is not ridiculously expensive. I bought the OEM Canon EF to EF-M adapter on eBay for $40 when the whole world hated the original EOS M and stuff was cheap. Don’t see that happening again.

Sorta makes more sense, but the thought of using an adapter never gave me a conniption.

Adapters are just not fun even if they're free. I'd rather just get new lenses, but if I'm going to do that, Sony has a lot more niches covered with their mirrorless EF lens lineup.

What do you mean, Sony EF lenses?

I personally preferred the native EF option, but a lot of people seem to manage fine with adaptors.

 

[SOD]

Although, certainly 50/1.2 is a niche that Sony doesn't have. Likewise with 28-70/2.0...

Sony best covers the 90% of niches remaining beyond those two lenses, and Nikon has nothing.

Sorry, Sony FE lenses. There are about ten good ones for every mirrorless lens of Canon and Nikon combined so far. And it will be this way for well into next decade. And yes, I was all about EF compatibility for Canon EOS R cameras. Considering the 300+ lenses that wouldn't require a janky adapter to mount.

What is the difference between mounting a lens to a flange on a body and mounting it to a flange on an adapter? I haven’t noticed any difference myself.

 

[Richard CN]

I think the point to remember is that it appears like it's not just your normal adapter, if it allows drop in filters, the benefit to EF glass is HUGE. you only need one set of small filters for your needs, you don't need them for every lens thread diameter.

Just tell me it has dual card slot and eyeAF and I'll forgive you Canon

Fat chance on either of those!

While in the ideal world, a direct EF mount would be easiest when changing lenses, but this would compromise future lens design.
I use the adapter for my EF lenses on my M3. I also use my 1.4x converter on my 200/2.8 and 400/5.6. Plus I use the EF extension tube and life size converter on various lenses. They are solid and work well. I have no qualms with an adapter for any new mirrorless. The key issue is the focusing protocol and mechanics. Most EF lenses are not optimised for focusing with mirrorless cameras. I expect that this will be the limitation, not the physical extension.
A smaller flange distance will give Canon more options in lens design.
I'm okay with that.

Advantage of EF adapter: wider opening in RF mount. More flexibility for RF lens design. Short term pain, long term gain.

I guess the previous rumor of a 'clever' solution referred to the drop-in capability.
