Third Party Manufacturers / Re: Is it time to consider Sigma lenses seriously?? competitive to Canon?« on: June 16, 2013, 03:04:10 PM »
This thread title made me very angry - it's Canon fanboys like OP that drive the insane Canon glass prices up. 3rd party lenses can be just as good as Canon's at fraction of the cost. Don't blindly recommend Canon's glass against Sigma, Tamron, Tokina, Samyang etc. - they all have some outstanding products, while having to reverse-engineer the AF communication.
