hey guys, im new here, been reading post after post in the beginners section. i will be purchasing a canon XTi as my first SLR (body only). and ive been shopping around for what lenses i should start off with. will this be a good lense for basic shots? http://www.bhphotovideo.com/c/product/423941-REG/Tamron_AF77015C_28_80mm_and_55_200mm_LD.html i think they are too slow, but since im a first timer, will it be sufficient enuf? also if theres something better thats a couple of hundred more, ill be more than willing to spit out the cash.
