I'm new to DSLR, as with most people posting in this section.
Just wanted to ask is it a myth or truth in that it is better to buy original or aftermarket lenses? In saying that, for argument sake we are comparing similar specs lenses to the same body and price of the lens is not in scope, and of course when comparing a $3,000 Canon lens, you would compare a Tamron lens of similar spec that would cost similar to $3,000 (if there is such a thing)
"Extremely" loose example:
Canon Lens vs Tamron Lens
Canon vs Sigma Lens
I've heard various things and mix reviews... =S
Thanks in advance,
