Just bought thisWhat to expect?
Disappointment

Is that a Sigma lens?
>>4129685WildlifeBird photography especially I came with protective filter and sigma dockUpgrading from a shitty Canon 75-300 kit lens
>>4129720>Upgrading from a shitty Canon 75-300 kit lenshope you don't use AF, since it'll be a downgrade from that. 3rd party lenses are notorious for bad AF especially at supertelephoto focal lengths
Nothing.A 120-300 2.8 plus 1.4 or 2 teleconverter (in case you need that reach) is all you need
