sigma lens with sigma tele converter ?
i have bought canon 450D before few days with kit lens. 18-55 that is enough for general photo. for long distance like wild life or bird photography i need good long tele lens. first of all i cant afford high prices lenses, Canon 75-300 is not good option because of its bad result and canon 70-300 is too costly. so i have turn back to sigma 70-300 APO DG MACRO F4.5/5.6, and apart from that i am thinking to buy 2x converter from sigma APO. this will give as per my calculation 960 mm i will get. ( 300 x 1.6 focal length x 2 ).
can somebody guide me is this combination fine for wildlife and bird photography ? any other suggestions will be appreciated.
suprising a pro photog does know about conversion factors or that a 2x converter reduces 2 stops of light.
The combination will be slow to almost useless on AF, on MF it will be a handful.
Bird photography is very difficult and as said above best with a prime and a 1.4. 960mm sounds great but your streching your optics alot there.....save for a prime maybe even a 200mm with a 2x will give you 200x1.6x2 which is 640mm which is pretty good and will be 10 times sharper.
Just my thoughts.
