Pentax DA★ 16-50mm F2.8 ED AL (IF) SDM

評測報告

* 對焦快而靜
* 色彩還原度高

* 光圈2.8時不夠sharp, 到F4後會有好的成像.
* 對比度都還是較高

鏡頭做工很好,變焦環在後面有點不慣.
光圈在F2.8影像十分鬆散,用F4以後有很好的成像.
對焦方面真的有進步,快了及靜了.
價錢還是貴了少許.

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??

- 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.

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)

f2.8

not fast AF enough

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