Interchangeable lenses
Sep 6, 2023 14:29:18 #
I own a canon 5D MarkIII but I want to upgrade to an R6 or an R5 are the lenses interchangeable amongst all of the models or do I need some sort of an adapter to use my previous lenses with an R5 or R6?

Thank you for the information do you happen to have the model of the adapter by any chance?

EF to,RF adapter, comes in three models.

Adapter, a straight forward one that works just fine is $150. Can be found on sale for $100. Bells and whistles are an extra $50. Only drawbacks to any I have found is they make the lens bigger and clunkier than the R versions and unless you want to constantly change the adapter each time you change a lens you need more than one.

The EF to RF adapter can include an internal filter or a control ring that gives another programmable control point for the lens and / or mirrorless camera. Those the three options in the Canon EF mount adapters, the basic adapter doesn't have the control ring nor drop-in filter option. That control ring mimics the control ring that is native to the RF lenses, something most mirrorless users find quite useful.

The one with the control ring has had a price drop to $150. The basic model is $100 so Im very glad that I spent an extra $50. Go for it.

I expect many Hawgsters will praise the most pricey model with the built in filter holder for pricey Canon OEM filters. Filter fetishism runs rampant around here ... cost-no-object !

Get the Canon control ring adapter. Avoid any third party adapters. Your old lenses will work on the R mount, probably better than they did on the dSLR. Native lenses would be even better, but probably not worth the trade-in and replacement costs.

Canon has yet to license any lens manufacturer to use the R mount electronics. No other manufacturer should have an adapter that allows an automatic lens to work properly.

I have a Canon 1v-HS, a Canon EOS Rebel 2000, a 5D Mark II and a 5D Mark IV. My lens are interchangeable between bodies. There are slight differences but I’m okay with them. The fact that I would need an adapter to use my existing glass with a new mirrorless body is the main reason I won’t switch. Yes you can use an adapter.
I wish someone can explain the reason for the contact changes between a dSLR and Mirrorless. I would like to think the additional contact increases the functionality or perhaps the distance of the rear element to the Mirrorless mechanism. I don’t really know. I am very partial to a R3 but I don’t want to lay out that much cash.
I hope that someone out of the Canon pros know.
Any word from Paul Sager, Paul Rubin or Bill Burkholder.

The reason for the need of an adapter is the fact that the distance needed from the rear of the lens mount to the sensor is different for lenses designed for DSLRs vs those for mirrorless. This is probably due to the fact that there is no mirror, so the camera's lens mount is closer to the sensor.

Dear Mr. Rubin: Thank you for your insight. I always thought that lens mounts were camera manufacturer’s way of keeping a patent viable. After a manufacturer went through creating a body they had 17 years before a patent allowed another company to copy the design. Thank you very much. Sincerely yours, Steven Gewirtz.

The contact change is not really relevant. What relevant is that the lens mount flange distance. If they design the RF mount to have the same flange distance as the EF mount then you lose one of the great advantages of mirrorless that you can have the lens sit much closer to the sensor than in an SLR. This is especially advantageous in wide angle lens design.
In fact Sony did that with their SLT camera. At the time they need the transparent mirror to have phase detect focus but with the new imaging sensor they have phase detect AF on the sensor and so they can have the same A99 or A77 without the mirror at all and use the same A mount lenses. But would anybody buy them????
