多0左個紅圈~~ 哈~~
其實又唔係好似神鏡咁勁, 又唔係全部鏡都咁貴, 呢家有D非L鏡都貴過某幾支L鏡~~ 睇下自己個銀包, 睇下自己0既需要去玩~~ 我見過有師兄0係呢個討論區, post過一張用EF-s 18-55 IS影0既貓貓相, 真係sharp得驚人, 支鏡都係大約一千蚊, 咁係咪一定要買L鏡呢??? 我自己都有用EF24-105 f/4L IS USM 同埋 EF70-200 f/4L IS USM, 兩支都出名係sharp鏡, 同埋對焦超快, 還原色準, 但係一支鏡0依家都要七八千, 咁就要睇下個人喜好啦, 我都係心理上覺得cool一D~~ 哈~~

one of the difference between L lens & non-L lens is the DISTORTION level, L lens usually have minimum distortion, while non-L lens may have larger distortion.

another difference is that many L lenses are enviromentally sealed, while non-L lenses are usually not

If L lenses are enviromentally sealed, 點解會伸長伸短?

1. I said MANY L lenses are environmentally sealed, not all L lenses 伸長伸短
2. 伸長伸短 = NOT environmentally sealed, yes
3. NOT 伸長伸短 =/= environmentally sealed, e.g. 70-200/2.8 NOT environmentally seal, but 70-200/2.8 IS environmentally sealed, all these lenses do not 伸長伸短
