我本身有ef17-40L 同28-135IS
我而家用緊350D,

17-40L雖然係好,但係1.6X後就得返28MM
未夠WIDE
所以諗好唔好放17-40而買入10-22
雖然10-22係EF-S,但係估計CANON無3-4年都唔會有平民FF機
(佢ARM ARM先出左支9千幾的EF-S LENS,無理由咁快出平民FF機打死自己支鏡)
EF-S都應該有排玩

但係都係有D擔心

[平凡的地夫]

Canon EOS-5D Body 行貨宜家賣緊$20600
你估下幾時會有FF 平民機丫拿?

Better buy Tokina 12-24mm F4, and keep 17-40.

唔使擔心, canon 話過會APS-C同FF雙線發展
到時你支10-22總有入門用家接

10-22, you won't regret.

Sold 17-40, you won't loss too much. Just go!!
