Yongnuo lens won't fit on EOS Rebel T3i

[Somenewguy]

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.

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.

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. 

[Somenewguy]

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  

[WCETECH]

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.
