Unfortunately, I don't understand your what your question is. It is likely a setting on your m3 that you may have accidentally set. Feel free to email me directly bruce at canoncamerageek.com and get real specific with what you want to know.



I'll update the post as soon as you answer.

Thanks,
Bruce

Lens Adapters For Canon t3i (600D)

(United Kingdom)

"I have just obtained a 6D camera that uses EF lens. Is there an adaptor so I can use the EOS lenses from my D600 on the 6D?

Thanks
Chris"

Hi Chris,

Thanks for your question about using a lens adapter to fit your smaller EF-S lenses on your larger 6D sensor camera. It's a great question because many of my readers ask similar questions on using the EF-S sized lenses on full sized sensor Canon cameras.

The EF-S lenses (intended for APS-C cameras like your 600D (t3i in USA) produce a smaller image circle of light traveling through the smaller lenses. The circle of light does not cover the larger sensor area of the larger full-frame Canon cameras.

There is no adapter to make it a bigger image circle. I made I short video that many, many of my readers found very helpful in understanding this confusing topic on Canon lenses and their compatibility with Canon camera. Here's the video: Canon EF Vs. EF-S Lenses

Thanks again for asking a good question,
Good Luck,
Bruce

Hi Bruce,

You just approved my question and
tried opening the attachment or Link you sent and it's telling me "No such page on this website" and "No such URL".
Is it a typo or am I just missing something. Thank you much.

Camera Adapter For
Canon 6D Mark II and 75-300mm Lens

by Steve Heinrich
(Wausau, WI)

What adapter is required for a EOS 6D mark ll and a canon EF 75-300mm lens?

Hi Steve,

Thanks for asking about an adapter for your Canon 6D Mark II and 75-300mm lens. The good new is that you don't need an adapter.

The 6D Mark II is a full frame sensor camera.
The 75-300mm lens is an EF lens. That means it has the right flange and a big enough image circle to work just fine with you 6D Mark II. The 75-300mm lens will also fit on the smaller APS-C "crop" cameras.

Here's a video for your benefit and others that explains sensor size compatibility for EF and EF-S lenses: EF Vs. EF-S Lenses

Hope that helps!

Canon FD to EF Lens Adapter

by John Losurdo
(Springfield, MO. Usa)

"Will a Canon FD 85-300mm f/4.5 S.S.C MF Lens focus or work on a Canon T2i using a glassless FD to EF adapter.

Thank you very much for your time. John L. "

Hi John,

Thanks for your question about using your FD lens with an adapter on a digital camera needing an EF mount. The Canon 2ti can take either EF or the smaller EF-S lenses and adapters can be used on lenses, like your 85-300mm lens, to get them to attach to "crop" cameras like the t2i.

I didn't start using Canon gear until well after the transition from Canon FD mount film cameras to digital EF and EF-S mount cameras, so I have no personal experience with Canon film cameras or Canon FD mount lenses.

With that said, because of the high demand for using film camera lenses on digital cameras, there are many sellers offering FD to EF (and EF-S) adapters. Generally speaking the ones with the corrective lens element included are likely to have better image quality.

The biggest issue for many Canon (and other) shooters is the loss of electrical communication between the camera and the lens when adapters are used.

Because the lenses (Canon EF and EF-S) for digital cameras are designed specifically for the light rays to hit the sensor at a perpendicular angle, I've stayed away from using lenses for film cameras on digital cameras.

It's a great way to save money and use your older Canon lenses-it's just that there are sometimes compromises that come along with these type of adapters.

I think you might benefit from reading the reviews of other photographers who have used such an adapter. Here's a link to read the reviews on one of the highly rated ones: Canon FD Lens to Canon EF Adapter (As an Amazon affiliate Canon Camera Geek receives a small commission from qualifying purchases, at NO added cost to you.)

Please let me know what your experiences are when you try one. They're definitely very affordable to try out on your Canon 2ti.

EF versus EF-S Lenses

Canon EOS-R Lens Adapter For Canon Rebel Cameras

by Unkown Canon Shooter

Canon R Mirrorless Lens Adapter

What lens adapter do I need for a Canon EOS-R to fit the lenses from my Canon EOS Rebel XS."

Thanks for asking about which lens adapter will enable you to attach your lenses from your Canon Rebel DSLR to a Canon R mirrorless camera.

Just realize that if you have EF-S lenses from your Rebel they will have a crop factor of 1.6x when used on the full frame Canon mirrorless camera like the Canon EOS R. Your R camera will automatically give you cropped images that are a property of the smaller image circle of EF-S lenses.

Canon EF-R Adapter

It's named just like it's function. It's called the Canon Adapter EF-EOS R. I don't know what Canon lenses you have, but if you have any EF lenses as well from your XS they can be used as well.

The 1.6x crop isn't a bad thing at all-you already had that occurring with your lenses mounted on your Rebel XS. It can be very confusing and I highly recommend you read my post (and watch the accompanying video) on EF Versus EF-S Lenses.

Coincidentally, I just used my Canon EF-R adapter to mount my EF-S 10-18mm to my Canon R and it works perfectly.

Stay inspired. Shoot your Canon!
