Sigma 10-20mm f4-5.6 EX DC HSM

Can anyone please tell me for sure if i need to apply the 1.6 crop factor to this lens 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?.
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 meduim 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

Hi Stephen and a warm welcome to TP.

You might be better posting this and your other threads in the relevant areas - i.e. this one might be better off in the equipment section, you might get more replies...

Hope you enjoy yourself here

No crop factor with this lens on a crop body, it's still a 10-20mm
