据说O的套头14-42据说比P18-55好太多了，有人比较过吗？说说看

呵呵，那位仁兄恐怕是忍者出身的吧。。。

O的光学素质是不错、但14-42相当于18-85、说比18-55好“太多”不太认同。

leica某纪念版套装
机身+50/1.4
这个50/1.4算套头

套头的定位就是入门，好也好不了多少，不要指望那个价格达到万元级牛头的画质。即使是被人诟病的佳能18-55，我觉得也不错

呵呵，不好意思，太爱说实话了。

.......你也太直白了点吧，虽然大家都心知肚明，但你不要把它捅破嘛。

大家讨厌谁很明显嘛！

O的14-42套头上不了1000吧，没什么人要的低档套头，不过性价比很好
比P的套头好没什么大不了的吧，怎么这么多P的人不屑呢？什么心理嘛，哈哈

松下这个M43头有没有软件校正呢？现在不信任松下，老玩这种把戏，哈哈

O的套头应该是最强的

小像場的優勢！！

ISO1600和3200，还不用后期？
简直无敌

要知道一只镜头好不好，自己用用就知道了。
你什么都没用过，自己内心里已经抱定了P镜头差的偏见，在这空口说瞎话，就有点惹人厌了。

不算无聊吧！顶多是楼主介于认真与天真之间

这样的帖子最是无聊

无聊的路过一次

了解器材就要客观，听别人把自己拥有的器材夸的一塌糊涂就高兴，听到别的品牌比自己的好的地方就不爽，呵呵，玩摄影的人如果是这个境界，我看还是不要玩的好。另外你这种回帖我看你也不配得到别人的尊重。肚子里没货可以不说话。说这些没用的大家肯定都会讨厌你。

楼主在群嘲呢没看出来么。
他说o家好就o家好呗，这么搞笑的问题，大家都别理他就得了。

没用过，看MTF图的话O家套头胜出，O家套头更锐利，P家套头在广焦段表现有些差，仅在长焦端色散表现稍好

The Olympus 14-42mm does well in our studio tests, sitting distinctly towards the top of the class. Indeed it's something of a talented all-rounder, doing pretty well in all tests and showing no obvious weak points.

Resolution This lens delivers consistently good results at all focal lengths, and unlike most of its competitors even gives good results wide open at telephoto. Optimum performance (unsurprisingly) tends to be around F5.6-8, although it's not at all bad wide open either. There's a noticeable loss in sharpness due to diffraction at F11 and smaller apertures, but Olympus have sensibly limited the minimum aperture to F22 at all focal lengths.

Chromatic Aberration Chromatic aberration is kept pretty well under control, and indeed overall is probably just about the lowest of any kit lens. The only negative is that CA is also visible wide open at the telephoto end, although here it disappears quickly on stopping down.
Falloff We consider falloff to start becoming a potential problem when the corner illumination falls to more than 1 stop below the centre. Falloff is only likely to be an issue with this lens wide open at 14mm, and essentially disappears on stopping down to F6.3 (there's also slight falloff wide open at 18mm). The falloff pattern on the tested sample was noticeably decentred with respect to the sensor.

Distortion
As usual distortion is most pronounced at wideangle, with 1.4% barrel at 14mm. This progressively reduces at longer focal lengths, and becomes essentially imperceptible from 25mm to 42mm. Yet again, a perfectly acceptable performance.
=====================================

The little Pentax kit lens is a distinctly competent performer, and tends to be very sharp indeed at apertures of F8-F11. Like all kit lenses, though, there’s a trade-off, and sharpness is nothing much to write home about wide open at the telephoto end; there are also some issues with chromatic aberration and falloff at the wider end of the range.

Resolution This lens is at is best at wideangle (at 18mm it matches the more expensive 16-45mm at 20mm), but somewhat indifferent at telephoto. As might be expected, performance improves on stopping the lens down a bit, and is generally best at F8-F11, prior to the onset of diffraction. As usual F22 and smaller should generally be avoided, and don’t even think about stopping down to F40 at 55mm; the results make us wonder why Pentax even bother offering this aperture.

Chromatic Aberration Chromatic aberration is overall quite well controlled; as usual it’s at its worst in the 18-24mm region, where the overlay of the red and blue lines indicates visually-intrusive green/magenta fringing. However the situation improves at longer focal lengths, and CA is all but invisible at 35mm and longer.  
Falloff We consider falloff to start becoming perceptible when the corner illumination falls to more than 1 stop below the centre. Falloff is pretty pronounced at 18mm, perhaps reflecting an element of under-design to the small-diameter front element. We measure a maximum of 1.3 stops wide open, which slowly but steadily decreases with stopping down all the way to F11. The situation improves at 24mm, and 1 stop wide open; unusually however we also see some vignetting creeping wide open at the telephoto end. Overall this is probably the 18-55mm’s weakest point.
Distortion
As usual distortion is rather pronounced at wideangle, with 1.4% barrel at 18mm. This changes to pincushion beyond 24mm, reaching a maximum at 55mm of -0.86%. This is more or less normal performance for a kit lens.

O家色彩也挺有味道的。。。。

不用这个头，松下的M43 14－45无论哪方面基本都比O的M43 14-42强两条街

咱是器材发烧派，会照相，不会摄影，为了仔细研究一下43、aps-c、全副的差异买来玩玩

兄弟搞错了吧，我从来没说那几张威尼斯的是用HDR搞的，是楼主说O那几张是HDR搞的

只是觉得宾得套头性价比非常好。
你要说O的套头，成像再好也拧不到P的机器上啊，是不？

我是在京东查的价格，器材城能便宜些，如果有拆机的就更便宜吧。

你说的O 14-54吗？14-42怎么可能要2xxx？

你们都是听说吧，我是两个头都有。不过拍片不多，说不出太多，说点直观感受吧。
1、锐度：小光圈锐度都不错。
2、色彩：看RAW，O家的色彩淡，P家的正常复原，或许和机身有关。
3、使用方便：O家的要拧一下才能用，和一般单反的镜头不一样，麻烦，而且不是内对焦，装不了CPL等滤镜。
4、价格：O家的2xxx，P家的2xx，少一位数字。

性价比肯定的P家好。别的差别不大，不如比机身，镜头没什么可比的。

晕，看到拿这张图来说明动态范围高，我实在看不下去了，你们知道这张图是什么地方吗？澳门的威尼斯人赌场二楼的人造“天空”，这个“天空”可不是真的天空，没那么亮。K10D直出JPG都能拍出这水平，还要什么HDR忽悠人：

兄台是干什么的？摄影器材商？

我记错了，不是14-50/2.8恒定，是14-50/2.8-3.5
L1是松下的机身，给徕卡贴牌的叫Digilux 3
