Architect1776 Loc: In my mind

Been having fun with a R7 which has the new RF mount.

I got this camera for the versatility that all RF mount cameras offer except for IBIS and the R7 has IBIS and is crop and those were the requirements.
Now this camera will use R, FL, FD, EF and RF lenses.
Add to that M39, Nikon F and a host of other lenses that the body's thin form factor allows to be used.
The photos are some examples of these lenses mounted on the R7 (Any R camera will do). There is IBIS, focus peaking and AV, TV, P, M and FV seem to all be able to make exposure adjustments along with ISO obviously for ALL these lenses.
1. Shows the original Canon breech Mount lens mounted, This mount never changed until the EF mount of 1987 the automation changed as time went on but this automation was very short lived.
2. Shows a FL lens with the exact same breech mount but the aperture control changed.
3. Shows a FD lens with the exact same breech mount and the added automation was added in 1971 until the EF in 1987 (16 Years and the breech mount lasted 28 years).
4. Shows the EF-s Lens (Just grabbed it could have grabbed an EF lens equally). The EF lasted from 1987 to 2018 or 31 years. The EF series lenses are totally compatible with the R cameras and no loss of operability no matter how old and have the control ring option that lets them have the same function as the RF mount lenses. So those invested with EF/EF-s lenses no issues using all of them.
5. Shows an old bellows attached to the R7 and using the FLM 100mm f4 and works very well, I even added a FD 2XA teleconverter to the rig and got some interesting shots, worked very well.
6. Finally grabbed on of my Nikon lenses to show it mounted, It was rough because the camera kept trying to reject it but with negotiation it allowed me to mount it.
PS, the bench these were shot on is our organ bench from our 1880 pump organ, thus the scratches and flaws.

Are you mounting it directly onto the camera or are you using a Canon Mount Adapter?

Really cool to see those beautiful old lenses put n that modern camera.

Architect1776 Loc: In my mind

I use the control ring adapter for the EF lenses.
I use a Kipon adapter for the other Canon lenses and a Urntl? One for the Nikon lens.

???!?!?!!!?
What does that mean ?

Is the OP using an adapter and if so which adapter.

What level of communication between each lens and the body.

User ID

Only an RF lens will fit DIRECTLY onto an R-body. For EF lenses its always Canons OEM adapter. For everything else, its just everything else (non OEM, see attached).

Figure it out.

Architect1776 Loc: In my mind

Control ring adapter for EF/EF-S lenses
Kipon adapter for R, FL and FD lenses.
Some cheap adapter for Nikon F.
Bellows uses the Kipon FD adapter.

Architect1776 Loc: In my mind

Control ring adapter has 100%compatibility with ALL features that EF/EF-S lenses have ever since the very first ones in 1987. Additionally all these lenses gain the control ring function of the RF mount lenses so basically they all, no matter how old, become RF lenses. This is unique to Canon.
The FD adapter allows all the R FL and FD lenses to function as manual lenses as they always did.
With the R cameras you can shoot by AV by setting the aperture and the camera adjusts the shutter. In P or FV mode the manual lenses also manually adjust the aperture and the camera adjusts the shutter. Or ISO if on auto aperture. In these modes you also have ease of under or over exposing.
In manual you set aperture and shutter and the indicator says under or over exposure.
There is no electronic communication as there never was originally.
But all the EF/EF-S lenses since 1987 again are 100% compatible and with the control adapter basically become RF lenses.
That is 31 years of lenses.
I was also proving that from 1959 to 1987 Canon NEVER changed the lens mount in spite of the lies spread about it by ignorant people.

How about Tamron. Sigma and Tokina EF lenses?

My experience is it depends on how old those lenses are. Canons past tense lens firmware seems to have contained some code for future tense uses. We are now in that future. Some older 3rd party lenses missed the boat on that code and will not work on later bodies.

Beats me why you bother with that here. Those evil doers never turn up on UHH.

But if it really entertains you, thaz what this site is here for, so rant and smile.
