Replying to Quick question +k for help

I picked up a t2i, still not very advanced with photography as you will see in this post but i'm determined to learn everything my t2i has to offer eventually.

I'm looking for some cheap lens that still have good reviews. This is one that i'm very interested in purchasing.


Helios 44 58mm f/2

just wondering if I would need an adapter to put this on my t2i or if it would fit onto the t2i without buying anything else. sorry for the noob question but please help me out!

thanks!
