Pro1 有變焦環 但係就 冇對焦環
而佢既變焦環係electronic linked... 而唔係mechanical linked

The Canon Pro1 is using a manual zoom ring, not electronic zoom like G serious !

Winkellun: According to dpreview.com's preview Pro1 is using an electronic zoom ring:

"Despite having a large ring around the lens barrel the zoom on the Pro1 is still 'zoom by wire' (electrically driven)", quoted from http://www.dpreview.com/articles/canonpro1/

BTW, acording to the spec (http://www.powershot.com/powershot2/pro1/specs.html), the RAW should be 8M in resolution.

um.... G serious 好似係連 zoom ring 都冇... 要用button zoom....

[Winkellun]

Sorry ! 原來我攪錯咗呀！睇番Pro1 個官方網，原來佢個 zoom system 同 D7X ,A1,A2 嘅機械式唔同，Pro1 嘅 zoom 係靠 usm motor 驅動，而唔係 usm AF ，只係以個zoom ring 代替咗 G 系等個zoom button，但個人覺得用 usm 嚟 zoom 而唔係放落 AF 度好似有啲怪怪咁！

Maybe it helps... Wonder if it gets distant zoom steps or a smooth operation (stop whenever you stop the ring), from the press release it seems to be the latter implementation which is better IMO...

Nonetheless a mechanical ring is probably more preferred.

Maybe some will consider Canon played a trick advertising it as an USM lens which tradtionally USM was used for the focussing system?

>>為何會無手動對蕉,變蕉,今次真係唔明canon搞咩？
唔係冇手動 對焦/變焦... 只係冇機械式 對焦/變焦 環...

>>Maybe some will consider Canon played a trick advertising it as an USM lens which tradtionally USM was used for the focussing system?
老實... 我真係有d覺得 USM zoom control 有d似 "卓頭" 野.....
