Using Canon 400D
I have googled and it seems to say
1) the sigma has better build but is heavier
2) the sigma has lower chromatic abberation and barrel distortion
3) the canon is sharper
can anyone confirm the above?
i think it all comes down to the image stabilisation question
- the sigma takes one second to image stabilize
- how long does the canon take???
both are $700+ on einfo.co.nz
