Can anyone please tell me for sure if i need to or do not need to apply the 1.6 crop factor to this lens ? Sigma 10-20mm f4-5.6 EX DC HSM
as it is specially made for a cropped body as someone has pointed out ? which would make it roughly 16-32mm by my maths on a Canon cropped body if i needed to ,.
Or not as its built specially for the ultra wide to be effective which a few others have suggested 10- 22 would be not be very good for medium to large groups, however if it is 16-32 mm it could come in useful i bought it as a landscape lens as its ultra wide and had lovely results with it but shoot on a EOS 550D AND A EOS 70D
