In a nutshell, I own a canon t2i and am looking for a few lenses (wide angle and long(er) range) and other accessories (such as a tripod, intervalometer, and eventually an external shotgun microphone). My question to you guys is, while keeping in mind a poor college student's budget, what are some affordable/ decent quality accessories that I should look into to expand within this hobby? It doesnt make sense for me to spend benjamins on a manfrotto tripod or tokina 11-16 2.8/canon 70-200 f4L because I wont be able to use them to their full potential. I am looking for stuff to learn/expand on before I get into any of the more serious lenses/accessories.
Also I am looking for a good camera backpack, so recommendations along those lines will also be greatly appreciated!
Thanks guys
