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.

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

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.

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.

Somenewguy — Sun, 03 Nov 2024 01:35:29 GMT

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

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.

Somenewguy — Sun, 03 Nov 2024 04:44:53 GMT

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.!

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

Somenewguy — Sun, 03 Nov 2024 04:56:54 GMT

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!

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

Tronhard — Sun, 03 Nov 2024 08:41:24 GMT

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.

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?

I'm just skipping to the end but if you want a 50 mm lens, I suggest you buy the Canon version with the correct mount. Buying from eBay is a gamble . If money is an issue buy from the Canon refurbished store. You can also look at the used departments at B&H, Adorama or KEH.

If the kit lens that came with the camera is an 18-55 or 18-135, you wasted money buying a 50mm. lens at all, if depth of field is the only consideration.. Set the kit lens at 50mm. and it provides the same DOF as a 50mm. prime.

"People" misled you.

Or are you looking for something else, like macro capability?

The assume the OP bought a 50mm f/1.8 for it’s larger f/1.8 aperture. A 50mm lens shot wide open at f/1.8 will not provide the same DOF as a 50mm lens shot at f/4.5 or f/5.6

If the OP wants more DOF, not less, then you are right, there will be no more DOF than the kit lens.

Since the OP was not more specific about what he is looking for, assuming anything is useless.

So i make dice, specifically for table top gaming, and i bought the dslr canon t3i to take better pictures of my finished piece sets than i get with my samsung galaxy flip phone. Here is probably the average pic ive taken with my camera so far using the kit lens, tripod, remote trigger, and setting at f16 to get maximum depth of field on aperture priority mode. these settings were recommended to me on reddit, obviously im new to this and reading a lot , what im looking for is much better detail, im working on increasing lighting, etc as well,

The specific lens you have mentioned so far is not known for its image quality -'cheap and cheerful' was one comment I read about it.
Most people buy something like a 'nifty fifty' for its low f/number of around f/1.8, which offers benefits to isolate a subject and allow low-light photography. However, as my colleagues have said, you don't want less dept of field close-up, you want more. Simply put, the higher the f/number - f/8 - f/11 or so, the deeper the depth of field. So, as Mike and Normandel have said, a kit lens from Canon would give you at least as good results.

If you were going to invest in another lens, you want something in the 15-35mm range. If you have one of the lenses: 18-55 or 18-135, that my colleague Normandel mentioned, I would start with that at a short focal length.

Set your camera to Av mode, and the f/stop to f/8 or f/11 and use Auto ISO. The rest of the task comes down to providing enough light from the right direction to give the best showing of your products. You might want to consider some kind of small tripod and use a remote cable or use the built-in timer to avoid camera movement.

Somenewguy — Sun, 03 Nov 2024 23:33:39 GMT

yeah im using a tripod and remote corded trigger so as not to move the camera, ill tray the settings you mentioned, on reddit i was told to go high like f10 to F16 to get max depth of field in focus as im really not wanting to learn focus stacking. i have almost 2 hundred sets of dice ill be posting up on a site for sale and to knit that many pics together would take me a novice, way too long, lol, thanks for th ehelp. ill just send this one back and try to get better at the kit lens before i think of trying some other lens

Lose the white backgrounds and kick up the lighting power a bit.

And go full Manual.

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

Somenewguy — Sun, 03 Nov 2024 23:47:39 GMT

to be honest ive had to go manual on the focus for sure because the auto focus doesnt seem to like shiny glittery filled things, lol

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

WCETECH — Sun, 03 Nov 2024 23:59:23 GMT

However I am referring to manual exposure.

Letting the camera body determine the shot you want is a guaranteed failure.

Add more light, open the F stop a tad lose all of the reflective backgrounds unrelated to your product and shoot your product like it was a collection of diamonds.
