As i've now got my canon 7d up and running i need to get myself a sports lens. Not sure if people on here will have had much dealings with sport related lenses but I've got a few options to have a look at. The ones within my price range so far are; http://www.amazon.co.uk/dp/B00005QF6T/ref=asc_df_B00005QF6T8917730?smid=A3CCL2LRPH3UU&tag=googlecouk06-21&linkCode=asn&creative=22242&creativeASIN=B00005QF6T then the newer version of that lens http://www.amazon.co.uk/Canon-70-200mm-4-0-USM-Lens/dp/B000I2J2SG/ref=sr_1_2?ie=UTF8&qid=1343254371&sr=8-2 Ive also had a look at the sigma 70-300mm http://www.mpbphotographic.co.uk/used-equipment/used-lenses/used-canon-fit-lenses/sigma-100-300mm-f/4-ex-apo-if-hsm,-canon-ef-fit-2/ Just wondered if people had any advice to give. I'd of gone for the 2.8 in the canon lens but its a little out of my price range. Got a bit of paid work now with sports photography including local press as well as going to london for a replay of the first ever fa cup final against wanderers fc and royal engineers. Open to other lenses. Looking at a price range of 500 up to about 800.
