Yongnuo lens won't fit on EOS Rebel T3i

New guy with a T3I, bought a lens and now im stuck

SO i recently bought a T3i, with the kit lens, i take pictures of a product ( i make dice), and people told me i needed a prime lens to get the depth of field etc and the pics i wanted. i use a lightbox, etc, so i bought a Yongnuo EF YN 50mm f/1.8 MF Lens for Canon , off ebay

Im sure you all probably know whats next, so this lens  doesnt fit my camera, so now i dont even know what the heck to look for, lol

so my questions are two fold.

  1. is there an adapter of some kind to fit this lens to my camera and is it even worth it?

  2. What kind of lens should i be looking for, what the big thing that i need to make sure of to make sure the lens will fit my camera. I assumed ef and ef=s are what fits my camera, now im completely confused.

Thank you for your help! Feel free to laugh at me. im terribly new to cameras like this.

I would not go to a higher stop the f/11. You risk diffraction issues that will soften the image.

Somenewguy:

Depth of field is determined by f/stop and magnification. Higher magnification yields less depth of field.

The picture of dice indicates you are getting very close to the subject . The closer you get, the higher the magnification, and the shorter depth of field you get. You were focused at the plane of number 13, which looks sharp. Everything in front of it and behind it is unfocused.

What you can do is , beside using small aperture, is back up some, get more depth of field and more focused dice, then crop the photo later.

Don't try to adapt it, return it for a refund.

Hi and welcome to the forum:

Well, according to the specs, the lens you have identified, the Yongnuo EF YN 50mm f/1.8 MF, should fit onto your camera without an adapter.   Either a lens with a designation of EF or EF-S will do so.  
So, assuming the lens has no fault, try watching the following video to see if that helps:

In your case, the lens has a RED dot.  You line that up with the RED dot on the camera body, rotate the lens until it clicks and you should be good to go.
If you still have an issue come back to us.

Since you are new to cameras and the T3i, here is the first in a series of videos on the operation of the camera.

i believe now based on the white circle dot as the camera lens contact that the lens i got is actually a EF-M lens which is why the mount is way smaller than my camera body lens mount. im trying to do a return now thank you for the videos too though, very helpful for other things.!

They don't make it in an EF-M mount, but if it's a white solid circular dot, then it is for the Nikon F mount.  You should return it and swap it for the Canon EF version - that has a solid red dot.  I hope you kept all the packaging etc.

thank you, but yes, it doesnt fit the opening is much smaller, im thinking maybe i got scammed and the lens is not what was listed in the listing and the box, ill take a pic in a minute and post it maybe thatll help, i also notice theres no red dot or white square on the lens just a white circle.

If the lens is much smaller, then it may well be for another system.  Perhaps an EOS M or another brand completely.  There are no adapters to go to EF or EF-S lenses from other Canon lens mounts, so it works or it doesn't.

This lens apparently comes if Canon and Nikon mounts, and if you ended up with a Canon one (hopefully by their mistake) then it will be smaller than the Canon EF mount.   I would check the lens and if it says anything about Nikon or F mount then it's definitely the wrong version. Either way, contact the vendor to see if they can help you.

yeah i have a feeling the model i wound up with is a ef-m  mount lens,  it has a white circle as the lens mount symbol, and according to what i can find online,  thatsthe mark of a EF-M which i of course isnt an EF or EF-s  juts like you figured. when i look up the part i listed  the ef mount version the red dot that i was expecting to see for the lens mount. So im working on a return , thank you for your help!

and imean the opening on the new lens is much smaller than the camera body opening

That's not all that important, what matters is the size of the mount how it attach's and the interconnections.

If they don't match 100% to the body you have then it is the wrong lens.

Who did you buy the lens from?
