What is your choice?

1) Sigma 10-20mm 3.5 EX DC HSM OR
2) Sigma 12-24mm F4.5 EX DG

最緊要係你用緊咩機先...
同埋如果第時想升FF機...就梗係12-24啦...

I am using Canon 5D mark I (FF) at the moment. So, you suggest me to buy 12-24mm? May I know why?

Tks.

if you get a good copy of s12-24, you will love its extreme wide angle of view

Sigma's codename...
DC = for crop-size sensor
DG = full frame

if you are using 5D, you can't use 10-20 f3.5 DC EX
