Sigma lens won't easily fit on EOS Rebel T5

Gaetan — Tue, 11 Jun 2024 15:27:24 GMT

Hello everybody,

does anyone ever tried to mount a Sigma 150-600mm F5-6.3 DG OS HSM on a Rebel T5 camera ?

regardless to the lense specification, it should work with EF mount, but I didn’t succeed. I had to force a bit, but even with that it wasn’t possible. Then I stop to not damage my equipment.

thanks a lot 🙏

Greetings,

The Sigma 150 - 600 Contemporary or Sport (for Canon EF) will fit and mount on a T5. It does not require any special adapters, etc.

Ok thanks you.
That’s so strange then. I guess it’s better not to force in any case. Should enter easily, maybe i am doing something wrong.

But I still have an interrogation. Is that normal that the lense and my camera don’t have the same number of little points for the connection?

Greetings,

Match the red dots on the body and lens. Mate the lens mount (camera) with the lens flange (lens) together evenly. Then gently twist clock-wise. If this doesn't work, the lens flange is damaged or the lens you have is not for Canon EF.

Shadowsports,

thanks a lot for the time you spend to help me and your quick answers !! 🙂

Okay, I think I was doing it properly but gonna try one more time.

I was also speaking about this number that is not the same on the body and on that Sigma lens. Is that something strange or doesn’t it matter??

Shadowsports is correct. Match the red dot on the lens with the red dot on the camera body. I am confident that your lens is for the Canon EF mount. It looks arguably identical to the mount on my Sigma 35mm Art lens.

I used use a Sigma 150-500mm with my T5. While the rig can be used handheld, I strongly recommend using a tripod or monopod with a monopod head. Whether shooting handheld or from a tripod, I recommend disabling OS in the lens and using a minimum shutter speed of at least 1/1000 to 1/1600. To use these shutter speeds, you need a bright sunny day.

Lenses with longer FL and some macros have 3 additional contacts for communication. Your mount looks correct Canon EF. The head of the screw closets to the red alignment mark appears scored. It might be that someone just tightened the screw holding the bayonet with the wrong type of screwdriver, or something has been disassembled.

So next question. Where did you buy this lens?

Hi Gaetan and welcome to the forum:
Is this lens second-hand but new to you?

Looking at the image that you included, I am concentrating on the screws towards the bottom of the screen. It might be lens distortion from the image itself, but the bottom left screw looks like it is not fully down, and the one on the lower right, just past the red dot, definitely seems to be burred or worn . Finally, the engagement lug (the hole to the right or above it again), looks to have some sign of wear - it seems to be showing a gold reflection, but that might be a play of light.

My temptation is to suggest that if this is a second-hand lens, it has been played with by someone who is not a trained technician and has possibly removed the mount and not put it back properly. Sigma does have a service where one can have a mount switched, say from Nikon to Canon or Sigma, but they would never leave the mount with burred screws.

Interesting question and replies. In my experience, forcing anything tells me something is wrong. Back up and determine why things don't fit. I have the Sigma 150-600mm Sport lens; does a much better job than I'm capable.

Thanks to all who read any inquiry and supply answers!

All the answers above are guesses. At this point, you need to seek out someone personally that is more camera savvy and have them check it out. With out hands on none of use can say for certain.

"I strongly recommend using a tripod or monopod with a monopod head. Whether shooting handheld or from a tripod, I recommend disabling OS in the lens ..."

I use my Sigma 150-600mm f/5-6.3 DG OS HSM Sports Lens on my 1DX and probably 90% of the time it is hand held. I also never turn of OS (Sigma's version of IS) tripod or not. It is a case of, if you must then by all means do but it is certainly not necessary especially for the lesser C or Tamron's G2 versions.
