請問各位師兄知唔知道這支鏡出左sony mount 未呀?
Tamron 網就有list , 但出去旺角行左轉, 間間都話未有...

[chow9500]

喱支野賣幾銀ar?

[fallbackskiing]

上Sigma, seem going to release F3.5, but not sure if expensive or not.

[artung007]

Tamron 10-24mm for Sony 上網睇過都係3800-4000
sigma有支10-20 都要3800-4000
到底邊支好d

[kwanwei]

已打去Tamron Hk 問過, 未返貨, 日本剛剛出, 所以要等等...

[artung007]

我買左啦..3680元

個人覺得sigma實淨d, 而且新果支sigma係恆定版

[magicianmax]

其實你恆定但係又唔係大光圈…
以B001 F3.5-4.5 差一級來說…3.5恆圈實際作用不多。

1. 你影風景一定會選最佳光圈…一般不外乎 F5.6 / F8
2. B001多死馬 4MM .
3. B001用 77MM 而死馬又用我最不喜歡的 82MM
(買塊UV都貴啦,82MM WIDE CPL 分明係買多三份一支鏡)
4. 向來龍仔都係比較SHARP, 而馬仔則好在色濃
(唔係點會咁多人買A16用，唔買馬仔那一支)
5. B001 比 馬仔輕幾十克

雖然馬仔有HSM…不過在ULTRA WIDE的世界…
要個對焦還行足全段的機會唔多吧…

如果有錯，請指點，勿插…THX

Not very sure, but if want to highlight some subject in the photo, then still need 大光圈.

If by that moment you find only have 20% cost difference but can take another effects, then.....

I do think a lot of situations, just most of the case we are not using but by the moment you want to use then you might ask why we do not spend this extra 20%

[chris262]

非也,
有恆定只是令你多個選擇而已
本人有比較過, 覺得sigma的較sharp
但龍仔的變焦較強
不評論對a16的想法, off topic...


當然,都係各有喜好,沒有問題的

[fallbackskiing]

Hi magicianmax Ching
恆定 means 24 also can get 3.5, right?
So 24mm also have 大一級光圈, I think..

I also see report in photozone and also sigma generally have a high performance marks. Just impression, might not fully true, 勿插... Thanks!

[chris262]

若以影風景計, wide shot通常長開f8
若於室內時, 由其沒有閃燈的情況下
雖不是f2.8, 但恆定3.5有助於遠攝端時,保持一個較大的最佳光圈

總好過,f5 收到7.1(舉例)


至於hsm, 廣角咁短焦, hsm其實作用真的不太
差不了多少

都係果句, sigma 10-20 屬EX系列
個人睇過相覺得表現較好(本人用舊版,恆定版用料更好)

而龍仔多4mm, 可視角達108 (10mm時)
各有所好


買咩都好, 自己鐘意就得

[fallbackskiing]

I see, F3.5 is better only at 室內時.

But 4mm only at 24 but not at 10mm (same 108deg la), myself 鐘意 Sigma more lo!
