你地會用什麼來決定買2.8定4呢？其實仲有無其他選擇?好頭痛!!

[ernest0430]

1) budget
2) 重量
有錢同可以負擔佢既重量 當然係2.8

[tupac128]

Have $$$, f/2.8 L IS II
Have $$, f/2.8 L IS I
Have $, f/4 L IS

Secondly, f'2.8 is heavier and more in price, but I will choose bigger f stop which I will need it for limited light environment and faster focus in dark area.

In my opinion, I will choose Canon only because they are simply better.

1. for 70-200, canon is better
2. i will choose 4L, because 2.8L too heavy for me
3. for indoor photos, i rather choose 85.8 for faster focus and letting more light in
4. above are my own opinion only, everyone could have different choices

Thanks All reply .........so if i use outdoor mostly maybe 4L (is or non is) is better for me ! Anyway is that any problem for old version 4L ? I hear it b4 but can't search for the web!

[homankop]

I think 70-200 f/2.8L is better,because 質素好過4L

[Mikuro]

For my own, I use the 70-200 with my BB so I have chosen from mobility with light weight. Therefore, I have chosen 70-200 F4L IS. :)

Highly recommend /4IS, the sharpest and the best color among the four present 70-200

[kenanet]

any compare photo for reference?

我之前都遇過呢個問題, 不過一諗下重量差成倍, 即刻知道點做, 雖然2.8係正, 但要我帶住佢去旅行, 真係唔好講笑....!

重量是一個問題

[speedstar]

今日先入左支4L
唔計錢既話, 知道自己係乜情況用支鏡多就唔頭痛.
如果係去旅行/行山用, 又係自助遊唔租車, 好似我咁, 就一定係4L, 2.8L更好都冇用, 太重太大支, 買咗只會放係防潮箱.

[火Ken]

重量係一個嚴重問題！！

[bho09]

I prefer the sharpness of 70-200 F4 IS

Don't argue the weight and price, see the differences....
