Hello I know there are some excellent photographers on here and was wondering if there was anyone who can break down the Tech into something more understandable when it comes to Lens Technology. I am looking to purchase a new Canon Lens because I own the EOS T2i Rebel (I plan to uprgade at a later date) and was considering an "L" series but I don't know which one to buy. A friend told me that typically high end lenses are permanent purchases, and its the body that gets upgraded. Overall I want a lens thats versatile. A lens that can take good landscape photos as I plan on Hiking a lot, as well as decent portraits. Also I like to spin fire poi at at night, and I often record and make HD movies with the footage; I will link an example at the bottom. obviouslly i'm an ametuer photographer and this is just a hobby, but what lens would best fit my needs? http://www.youtube.com/watch?v=RvLU-btnOWU&hd=1 I also use Appeture if that is relevent in anyway. Suggestions? thanks in advance.
