唔好意思, 我o岩o岩學影相, 想買支長d ge鏡
呢兩支鏡, 買邊支好d呢?

Sigma 70-300mm F4-5.6 DG MACRO
Tamron AF 70-300mm F4-5.6 Di LD Macro 1:2 (A17)

同埋, 買鏡時要留意d咩呢?
係咪應該帶埋自己部機去試呢?
我未試過自己去買鏡架, 所以都唔知應該點做...

唔該駛~~~~

我都考慮緊買支長鏡, 我會選擇Sigma 70-300mm F4-5.6 DG MACRO水貨. 其實兩支都差唔多, 不過比較多人用Sigma因為可以crack全程marco.

check其實唔難, 在shop的白光管下把鏡舉向上, 用眼睇睇多唔多塵, 少少實有的. 另外把AF轉做MF, 再轉動對焦環, 睇睇有冇塵及其他黑點出現, 當然亦要CHECK外觀, 對S/O number...等.

大致係咁, 如有更正, 請各高人指點~

There is a lever at the back of the lens to control the aperture, push the lever so that the aperture is wide open and either point the lens to or away from the light source, check if there are any bubbles and dust in the lens.

My passing criteria is that there is ABSOLUTELY NO bubbles in the glass, and the dust is of acceptable levels.

If I am starting in photography, a tele lens is of little use unless you like shooting in this particular setup. I'd say a lens in the normal zoom range would suit you better.
