新P老P双P对决: Panasonic 14mm f/2.5 on the GH2 and the Pentax 21mm f/3.2 on the K-5
虽然是山寨版对决, 但是还是挺认真的: tripod, self-timer, aperture priority autoexposure, shot in triplicate, processed with default Lightroom 3.3 sharpening and NR plus
default Nik Output Sharpening which maximizes detail but also increases noise and artifact
对决结果总结:
1. 新P老P饼干头锐度相当, 无论是中心还是边角
2. 新P饼干头焦外胜出! 油润, 德味!! XD
3. 新P老P对焦决后感: 都说K-5对焦大幅提高, 但是, 大家普遍反映: "The auto focus of the GH2 seems to be much more reliable. I consistently get sharper images
from the GH2 vs. the K5", "My K5 AF is pretty good, but the GH2 AF is better. Faster, quieter, more reliable, and better able to get a lock in low light."

老P的DA21焦外不是一点点悲剧

所谓做工, 不过是新P多用塑料,老P多用金属巴了. "The build quality of the lens
is excellent despite the low weight of merely 55g."
在镜头材料和成像的焦外两个中间, 你选哪个呢?

14 mm的广角还能有焦外，这也就43上能看到吧

我对14mm的噪点很不满意，按说gf2的iso比gf1强一点点，但我觉得800iso的gf1+20mm
比400iso
的gf2+14mm好

以前我用O+狗头的时候，低感暗部噪点也不少。我以为是机器的问题，可是换上了20神
头，就好多了。

一个等效28mm，一个等效30.5mm
为了达到画面主体范围大小一致，
新P的14mm必须更加贴近主体，
这前后距离透视都变了，还比个啥虚化阿

等效28mm vs等效30.5mm, 多大的差别阿. 光圈4/3上的2.5和APS上的3.2也很接近.
再说了, 比的又不是虚化能力, 而且虚化能力也差不多, 比的是焦外阿.
sharper

老P的21mm很挫，国内无忌上基本都是小光圈超焦距用的
老P的对焦系统本来就烂，在这个烂头上还要减2个level |
