一鏡走天涯
SDM可自行維修或改機身screw
鏡身防塵
二手價賤（特別死SDM無Hood）

F2.8成像一般
F3.5打後Ok

此鏡F2.8成像軟，除非影人

1. 好sharp！頭段到尾段都出色。其micro-contrast 更加正。
2. 16mm 夠濶，比其他大廠副廠的17mm，影大景或打巷戰時，就係優㔟明顯。
3. 賓德*鏡，其防塵防水滴的壓倒性強勢，用家都會心領神會的。
4. 影風景D色彩靚到令人醉！尤其是藍綠色，其他廠的無出其右！
5. 對焦既爽且準，很少 hunting，暗位對焦尤其出色。
6. 星芒利到拮手，—見鍾情。
7. 做工細緻，外形師氣，㵂光罩夠霸氣！

1. 重，但已經比大厰輕D，和副廠差不多。
2. 大，但又有冇其他廠比佢細呢？

1. 初初唔敢入，因為怕SDM易壞，所以最初用「死馬」的17-50，都很满意。後來網上話，如果SDM壞咗，可以轉用 screw drive auto focus 。而又見到有件極新淨的賣$3000，馬上入咗。

2. 同「死馬」做咗一個月的比較，結論係：夠濶很重要，色彩勝，锐度勝，對焦平手，做工小勝，星芒大勝，防水防塵狂大勝，所以馬上放咗支「死馬」！

3. 現在後悔買得太遲，錯過不少星芒靚景

我曾有過da16-45齊體都比da16-45較好
用wide果邊少許變型，影風景收到5.6光圈以上成像已很好
中間焦段恆定2.8可用
tele果邊略收光圈影人都唔錯
sdm夠靜 夠準
防塵防水滴設計

比16-45貴幾倍
插上舊機有機會走焦

黎支經常都會用到，影人影景都好岩用，個防塵做得幾好，用左咁耐無入塵，除左對焦比人略慢，其實無咩投訴

- large aperture standard zoom, useful range
- weather resistant
- quite sharp when stopped down
- color saturation is good
- good build quality

- SDM not reliable and not fast
- not sharp enough when not stopped down

Would recommend this lens to Pentax Chings, as there's not other lens that can do the same with it, large aperture, standard zoom range, weather resistant, these are already worth the money. For my personal experience, this lens saved me a few times in raining shooting situation, which has proved it weather resistant very well. There are times that I shoot on the beach and got wet with sea water, and it can be cleaned by shower without any problem. The main complaint with it would be the SDM, sometime it just not very reliable, and quite slow and need hunting.

1. 鏡頭設有九片光圈葉，散景來得相當自然
2. F2.8 的成像質素整體而言並沒有教人失望
3. 好有Pentax 的色彩
4. 鏡頭做工一流

1. 非常貴
2. 好重!

I am quiet satisfy with this lens, it give me the "Pentax color tone" taste which back to the age of "SMC-A" lens.

It already me standard lens and all the time mounted with my K-7.

HK$7380 Feb-2009

SDM對焦寧靜, 對焦速度亦比非SDM稍快
畫質有 43mm定焦 sharp. 77mm定焦紫邊.
唔會覺得很膠
鏡頭做工一流,成意之作.

香港賣到7k 幾, 非常貴
大了小小, 重了小小.

用慣三公主, 對焦慢一點, 但用了da* 16-50 ,對了焦也不知, 一個字"快"
畫質比得上大公主.
在k20用對焦速度快.
在k-m用對焦速度比k20仲快.
在k-x用對焦不知會不會比k-m仲快.
買了不後悔.

16mm x1.5=24mm影風景, 變形控制尚算良好, 影景一流
全開光圈2.8已很滿意, 收到4很銳利
SDM對焦寧靜, 對焦速度亦比非SDM稍快

香港賣到非常貴, 5k多少少左右才較值得入, 2手和水貨是較佳選擇
SDM比其它廠的超聲波馬達都仲是慢d, 唔算令令人滿意

呢枝鏡有一定的近攝力, 我扭到去50mm, 影食物一流
換算24mm-75mm, 影景影人影物, 非常方便
現在我出街如只帶1鏡, 想輕插DA21, 不然一定是它DA★1650

f2.8

not fast AF enough

not very sharp completed with N, but it is cheaper then N also.

-Provide nice Colours n details
-16mm
-Nice build up
-f2.8 is reasonable sharp, f4 crispy sharp

-Got Tokina Version
-QC not so good
-Expensive, more reasonable if below 6K

I believe kwok1118 dont even know what he is talking...
-No Marco<--the Marco is 0.35x, what do u expecting? 1:1?
-non-IS<--why Pentax need IS?
-Plastic outlook<--so u need shinning metal outlook?
-Hood is option<--it's included

Funny part is "comparated with other L lens", do u know this is PENTAX lens??

唔會覺得膠感重!

No Marco, non-IS & Plastic outlook, Hood is option.

Satisfactory performance (comparated with other L lens) & Light weight (easy carry)
