Lens Problem On new Canon 5D Mark 4
Dec 31, 2021 16:16:31 #
I just purchased a Canon 5D Mark 4 which is an upgrade from my old Canon T1i (yeah finally). I have 3 lenses (all EF mount) that I have been using successfully on the T1i. My understanding is that if it is an EF mount it will work on the new 5D. These lenses are: Canon 50mm F1.8 STM, Sigma 10-20mm F4-5.6 DC HSM, and Tamron 18-270mm F3.5-6.3 Di II VC PZD. The Canon lens works fine but the Sigma and Tamron lenses produce photos that look like they were taken through a round tunnel. The edges are blacked out like a vignette. Again, these are all EF mount lenses and they mount fine. Anybody have a suggestion as to what's going on?

They are Dx lenses being used on a full frame camera.

EF or EF-S mount? EF-S are for APS-C format cameras, like the T1i.
The two lenses that have the vignetting are probably APS-C format lenses.
I have a Sigma 18-200 for my T1i that will cause vignetting on a full frame camera, if they will mount. It explicitly states APS-C.
The 50 is for a full frame, as I have a Canon 50 ƒ/1.4 for my T1i.

I have a T5i. EF lenses (full frame) the mark on the lens lines up with the red dot on the camera body. EF-S lens the mark on the lens lines up with the white square on the body. As others have noted an EF-S lens on a full frame body will give you what you are seeing. Some full frame bodies can be set to shoot crop, I don't know about your new camera.

Yep, those two are crop sensor lenses and they don't throw an image big enough for a full frame lens. The Canon lens is a full frame, on your old crop sensor body it was acting like it was an 80 mm.
Now to get some full frame lenses for the 5DIV.

No the 5DIV is full frame only, the R5 mirrorless does full frame or crop sensor.

Good to know. All my lenses other than the kit lens are EF, so if I ever move to full frame I'm good. But my next camera will probably be mirrorless anyway.

Ef-s lenses will not fit on this camera
But the third party lenses makers use the EF mount on all lenses for Canon bodies so Tamron, Sigma, etc. crop sensor lenses will mount and work on a FF Canon body-you just get the round image in the middle of the frame. If it is a very wide or ultra wide lenses it is worse. I once did a test series with a 6D and a Tamron 10-24 crop sensor lens and found that from14-24 the images were useable, 13 was iffy and below that the vignette got worse until at 10mm with the flower petal styles lens hood on you actually got the shape of the hood all around the image frame.

Are you sure the lenses in question aren't EF-S mount?
Jimmy and to our OP Paulwms:
Only Canon builds EF-S lenses that mount to cropped EOS DSLRs at the square white box mount point. Third-party lenses all mount to the red dot of the EF mount, even those designed specifically for the cropped EOS bodies, also called 'DX' that is the Nikon equivalent of a cropped sensor body.
The Sigma "DC" lens indicated this is a lens for a cropped body. You can confirm directly from Sigma for this lens model.
The Tamron "Di II" lens indicated this is a lens for a cropped body. You can confirm directly from Tamron for this lens model.

Thanks for the replies. They are EF mounts but I was not aware of them being crop sensor lenses. I thought if it was an EF mount it would work. Thanks for the help.
