EF lens compatibility with EOS R7

[Nappert]

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.

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!

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!

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.

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 The EF-S 18-55mm kit has been replaced by the RF-S 18-45mm F/4.5-6.3 IS STM kit lens. Also your current EF 50mm prime lens (assuming you have the EF 50mm F/1.8 lens) has been replaced by the RF 50mm F/1.8 STM lens. Also the EF-S 55-250mm F/4-5.6 lens has been replaced by the RF-S 55-210mm F/5-7.1 IS STM lens.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.

Thank you for the tips.

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.
