EF lens compatibility with EOS R7

Nappert — Tue, 31 Oct 2023 12:59:03 GMT

Newbies here. We're wondering if we can get my daughter's Rebel T1i lenses (EFS 55-250; EF 50mm; and EFS 18-55) to fit/adapt to our new EOS 7. Thank you for any help.

Do you mean the 7D series DSLRs, Rebel T7 or the new R7 which is a mirrorless camera. If you're talking about the 7D series DSLRs or Rebel T7 no adapter is needed. If you're talking about the EOS 7 Series Film cameras your lenses the EF-S 18-55mm & EF-S 55-250mm lenses ARE NOT compatible and they WILL NOT MOUNT at all. Only the EF 50mm lens will mount on an EOS film body. Please list the full name of the lenses that you currently have. The EOS R series requires an EF/EF-S-RF Mount adapter to use those lenses. Note NOT all adapted DSLR lenses fully support all features on the EOS R Series.

What camera did you purchase exactly. If it's the EOS R series cameras. Stick with the Canon brand adapters. Third Party adapters cause all sorts of problems.

Makes sense to stick with brand. We are SO new a lot of this us over our head. We're going to a camera shop tomorrow! But we look forward to spending more time on this site learning, looking, and sharing. Appreciate your willingness to help.

Do you know exactly what you're looking for feature wise in a camera. It would be best to look into the EOS R series. Mirrorless cameras are quickly replacing DSLR cameras. Currently we have 2 sensor sizes those are APS-C & Full Frame. Full Frame is a throwback to the film era. 35mm film measures 36x24 just like a Full Frame sensor in a digital camera. APS-C is smaller than 35mm film. Your current camera is an APS-C camera. Would you like to stick with that or move to Full Frame. The EOS R series APS-C lineup consist of the R100, R50, R10 & R7. I have listed them from beginner to advanced. Then for Full Frame you have the EOS R, R8, R6 Mark II, R5 & R3. There were also the original R6 & RP which have been discontinued and have been replaced by the R6 Mark II & R8 respectively. I have listed them from beginner to advanced. Since you mainly have APS-C lenses I would look into an APS-C camera. Some of the newer cameras such as the R50, R3, R7, R10, R8 & R3 offer a newer multi function hot shoe. That offers better communication features with newer speedlites and transmitters such as the EL-5 & ST-E10 transmitter. The R6, R6 Mark II, R5, R3 & R7 offer IBIS (In body Image Stabilization). Which can help with lenses which lack image stabilization. Note when EF-S are adapted to a Full Frame EOS R series camera. Image sensor capacity is reduced by a factor of 2.5x. For instance the EOS R5 is 45 megapixels in Full Frame mode but in 1.6x crop (APS-C Mode) the camera is now 17 megapixels. I wouldn't recommend Canon's EOS M series lineup. It has largely been discontinued and replaced by EOS R series APS-C cameras.

Yes, you can use your current EF-S and EF lenses with the EOS R7. The R7 has what is called an APS-C crop sensor and the EF-S lenses are specifically designed to work with that size sensor. EF lenses will work with Full Frame or APS-C cameras. As mentioned you will need an EF-RF adapter from Canon (preferably).

Other bodies that would work with your current lenses are the EOS R10, R50 and R100 each being cheaper and offering fewer features than the previous in the list. The R7 is currently the best in class.

Thanks Trevor. We do need to spend A LOT more time learning things in the Canon manual. We barely know how to take a clear photo! Thank you for the reply. We're hoping for some decent photos on our upcoming trip.

Nappert — Sun, 01 Oct 2023 21:23:34 GMT

Thank you again. As for what we want...just good pics. Close up. Distance. We leave for an Overland road trip in a few days and will just have fun taking pics and scour the manual later. Again, really new newbies!

Do you have a specific budget in mind and do you have any requirements. If so list them if possible so @Tronhard and I can find the best camera for your needs.

I recommend watching some videos on photography in general. My go-to starter videos are from Chris Bray, who is an Australian National Geographic Photographer. He has a very relaxed style and will take you through the basics.

If you have access to your local library on-line catalogue, I suggest looking for an item called LinkedIn Learning. If it is available, you have free access to an immense array of professionally-made videos on all aspects of photography - everything from the very basics to advanced techniques.

We purchased an EOS 7 bundle. One lense. Will work for us, was hoping daughters old DSLR Rebel lenses were compatible. She has 4, all with different strengths. We will improve each day, each tutorial, and each page of the manual!

Re: Lense adaption

deebatman316 — Sun, 01 Oct 2023 21:43:43 GMT

I just want to confirm that you bought an EOS R7. Or did you buy a 7D, 7D Mark II, Rebel T7 & Rebel T7i DSLR camera body models. Canon hasn't made and "EOS 7" camera in years and they only used that name for EOS Film bodies. If it was a DSLR body no mount adapter is needed and your lenses will mount natively. This is what we're trying to confirm so we don't give you incorrect information regarding your camera.

My bad...EOS R7. So many letters and numbers...lol!

Re: Lense adaption

deebatman316 — Sun, 01 Oct 2023 22:37:04 GMT

That's a very good camera. That's Canon's top of the line APS-C camera. With IBIS your lenses will be stabilized too.

Re: Lense adaption

Note the EOS R7 DOES NOT have a built in flash like the other APS-C R series cameras. Or even its predecessors the 7D series. So if you need a flash an external speedlite would need to be purchased separately. 3rd Party speedlites often cause problems. I would look into a Canon speedlite if flash is needed. Also depending on your budget and what kit you're getting. The EF-S 18-55mm kit has been replaced by the RF-S 18-45mm F/4.5-6.3 IS STM kit lens. Also your current EF 50mm prime lens (assuming you have the EF 50mm F/1.8 lens) has been replaced by the RF 50mm F/1.8 STM lens. Also the EF-S 55-250mm F/4-5.6 lens has been replaced by the RF-S 55-210mm F/5-7.1 IS STM lens. Note these new zoom lenses have shorter focal lengths compared to their older counterparts. They also have newer faster AF motors too a lot of older lenses did not have. A lot of older lenses used slow AF Motors called "Micro Motor" and lacked image stabilization. But some of the lenses in the EF-S Mount were upgraded STM and added IS. STM stands for Stepper Motor & IS stands for Image Stabilization. STM AF Motors are quieter and faster. IS allows you to use slower shutter speeds and eliminate camera shake while taking hand held pictures in low light or with long lenses. Also note that newer lenses all utilize what's called "focus by wire". The focus ring is NOT mechanically connected to the lens' focusing elements. Instead the focus ring is electronic.

I hope some of this might be helpful.

I suggest practicing near your home before you leave on your trip, even if there are no photos you would want to save or show to other people make hundreds of photos.

If you have a large enough memory card, then set the camera to record both RAW and JPG so that when you get back from your trip you can adjust things like white balance and brightness in the Canon DPP software.

For me, the old EF-S lenses work better on my newer RF camera than they did on the old camera, but the new RF-S lens that came with your camera is likely better yet.

The PDF of the camera manual can be downloaded to a cell phone for viewing while you are traveling.

Hi if I may ask a sort of a follow up question. I have the 7D ( nearly 12 years old) and bought the R7 2 years ago. Both have the kit’s zoom lenses 18-135/150

i also have the adapter.

my question is: is there any advantage to use the older 7D’s zoom lens over the R7 ? The older one feels more heavy and not as “plastic lens” as this of the R7.

thanks very much 🙏🏼

I do not have the RF lens, but sometimes use the EF-S lens with my EOS R5. I think that the EF-S18-135mm f/3.5-5.6 IS USM is a very good lens with fast and accurate auto focus. It was listed by Canon as a lens recommended for depth composite/focus stacking.
