Tamron SP AF28-75mm F/2.8 XR Di LD Aspherical (IF) (A09)（已停產）

平
sharp
對焦很快(D300上)

吵了一點
對焦暴力

今日買了支二手的,$1600
一個字, 正
我用的是D300, 對焦其實很快的, 但有點暴力
剛和 nikon 18-105 做了比較,不論是對焦來回速度, 還是準確度, (cal 後), 也是 A09勝
我這二手的有小小走焦, 但在 f/2.8景深以內, D300微調後完美,
出名的迷焦問題也未曾出現
必買的好鏡

Sharp Sharp Sharp Sharp Sharp. I have bought about 20 lens. This is the only one make me very impressed. I can say you do not need to buy any famous lens. You just buy this one for human photos taking is definitely enought for your camera life. The excellent and the top quality picutre this lens shows.

Nil Nil Nil Nil Nil, base on the price is $2850 HKD only. I wonder why I need to buy the other famous lens if I have this lens. I never try Canon 24-70 and Nikon 24-70, but I believe it is hard to tell the different while you watch the picture from these three lens. I mean the Tamron have power to fight with the top Canon and Nikon lens.

I have Canon 24-105, and I have this Tamron 28-75 at the same time. I assure you this Tamron lens is sharper than Canon 24-105 very very very very very very very very very much. On the other hand, I cannot say which colour is better, because the picture quality of Canon 24-105 showed a little bit warm and red. Is the real human look like a little bit warm and red? Is warm and red picture is good? I preserve about this point. I don't konw. Tamron seem showed more real colour, special you taking photos from human, it showed the world more real. This is just my personal opinion.

無紫邊問題, 放心在強光下影相,色水一流

比nikon同spec鏡售價偏高

此鏡集實用及高成像質素於一身

1.假定用在full firm相機,焦段一流28-75mm，人像,風景都好!!
2.恆定光圈2.8，光圈全開影人像，成像也極佳，色彩柔和，亦不過份銳利。
3.體積及重量，也是同類型中最輕最短,高機動性!
4.價錢合宜，容易接受。

1.低光時較難對焦，時常失焦(可試單點對焦，成功率較高)
2.鏡身不太紮實，虛位易鬆。(相信較易入dust)

它是本人一支主要的人像用鏡頭(夠輕 及 28-75mm人像夠用)，我鐘意它的成像質數柔和舒服,較貼合影女像需要。

1. 如果響室內影相，你會發覺2.8 光圈係好正的
2. 影相主體(特別係靚人)好容易做到淺景深，好特出
3. 1手2300都有，2手價錢更係唔使2000，真係好抵

1. 暗嘅地方真係幾易迷焦，就算唔迷焦都要對好一段時間
2. 用響部400D可以話唔係太wide，映相要退多兩步囉
3. 從焦距上可以話係：wide又唔夠wide，tele唔夠tele

支鏡重量亦好，適合帶出街，
而且映人個效果真係好好，啲色好sharp，所以我經常插在機上
一般空曠地方可以走多兩步，使用上都無乜焦距限制

支鏡主要映人，所以用來影咗一次catwalk。
因為場地氣氛關係比較暗，迷焦情況出現。
光圈雖然大，但係stage遠，真係唔太zoom到個model，
何況個model會停一停俾人映相，相比大光圈作用比一般zoom得嘅鏡無咁大作用
所以如果想響特別場合映人，唔得

所以總結，一般街映人/景，首選
去旅行：最好夾支wide
出function：夾支小小白

1) 成像係同級鏡頭中最好
2) 價錢已經超值
3) 銳利
4) 夠輕

1) 暗位對焦好慢, 甚至對唔到
2) 光圈全開好易走焦, 收到f4就差唔多喇
3) 散景好一般

有人話a16好, 但我覺得始終都係a09最好....
無論變形控制同黑角都比a16好好多....
但係冇usm始終對焦都係慢左d.....
如果新手黎講已經夠哂玩.....
本人已經放走支鏡, 因為嫌對焦慢....
(可能我高要求)
但係呢支鏡真係一絕!!
