Tarmon !!

I have Nikon 70-300 mm ED and Tarmon 70-300 mm LD

Nikon AF is faster than Tarmon. But image quality / color.... I like Tarmon more. Tarmon has macro and good price $1250.

This lens was not owned by me, but it is impressive.

$1500 Hong Good...........is really a bargain....

好多謝各位^^~

小弟重有個低B問題....
鏡頭用mm來計算...我知道每支鏡都有最近對焦點..
和無限遠...係咪??
但mm是點介定??例如70-300mm係代表咪??我只知道係遠攝
28mm係廣角咁...其實我都唔知應該點問,希望有師兄明我點咩啦^^~

不如咁問啦...
70-300mm//70-200mm.....我知道前者長後者100mm...
咁實際係長幾多??

[tam_dominic]

70-300mm is a zoom lens

Zoom lens can change its focal length
ie from 70mm (widest) to 300mm (longest) in this case.

50mm F1.8 is a prime lens which cannot zoom ie cannot change its focal length.

Zoom lens gives you convenience to compose a photo
Prime lens gives you better image quality.

Hope this helps.

Happy shooting !

呢度可以睇到200mm同300mm差幾遠,實際上只係多啲啲.
