sigma dp2m镜头畸变控制很好，拍建筑、人变形不大。

呵呵，预料之中，就是D800+35G都未必能干过二妹，更希望有SD1M+30定焦头（死马自己的30/1.4或者30/2.8）同台PK场景！不出意外的话法兰距更短，镜头专门优化的二妹应该略胜SD1M

貌似白平衡搞錯了。

国外比较Sigma 30mm f2.8安装在索尼Nex7上和DP2M固定镜头的表现，结果DP2M完胜。

nex7 aa filter removed compared to DP2M

This is kind of a funky comparison because I'm using the Sigma 30mm f2.8 on the nex and the built in 30mm on the DP2M. The nex image is also bigger and is resized down for comparison purposes.

First on the lenses. It is impossible to separate out the lens from the sensor but I find the Sigma DP2M lens to produce better images from f2.8 to f8 than the Sigma 30mm f2.8 EX for the Nex camera. They appear to be equal in the center but the edges go to the DP2M without question. The 30mm EX lens is not bad at all, it's very respectable but it isn't the equal of the DP2M lens on the edges. Even at f2.8 the DP2M lens is sharp all the way across the image on a flat target and of course gets better through f5.6 then declines due to diffraction at f8.

I had originally intended to do a lot of tests but I am finding the DP2M so much better in resolution than the Nex 7 I don't think it is necessary to test much more.

These are images of the same piece of a rock shelf at the beach. First the sony Nex 7 image was resized down to match the Sigma image size. Then a small patch of the image is doubled in size 3 times so the final comparison images are magnified to 8x their actual size. All the enlarging was done with Irfanview using the lanczos algorithm.

A couple of other things. I think the Nex 7 is more sensitive to diffraction than the DP2M. This is quite likely due to the smaller pixels. The difference in appearance between f5.6 and f8 on the NEX seems significantly more noticeable on the NEX than on the DP2M.

Second, the more the images are enlarged the more you can see how the NEX image with the Bayer filter begins to fall apart and degrade. It's not important to images at normal sizes, those look fine, but it is evidence that there is a significant difference between the two technologies. Moreover the finer the detail at the most minute levels, the better the information and resolution at the visible level of the final image.

I can't quantify the difference between the two cameras but I can say I find the DP2M images to be more satisfying to my eye by a significant margin.

Here are the images

The first image is an unmodified jpg from the DP2M with sharpening set at 0:
Gallery image not found.

The second is the same image with sharpening set to -2 in spp resulting in no sharpening.
Gallery image not found.

The third image is an unsharpened jpg processed in Photoshop CS 5 with sharpening turned off:
Gallery image not found.

and finally the fourth image is the jpg as it comes out of the NEX7 unmodified.
Gallery image not found.

It's pretty obvious at this level of magnification why the Sigma produces better images. What is surprising is how the unsharpened Sigma image seems at some level sharper than the sharpened image. When viewed at normal size the sharpened image is noticeably sharper but when magnified the sharpened image actually seems to have lost detail compared to the unsharpened image. Much of the fine structure has been smoothed out. To me this is counterintuitive.

As far as the nex images go, it's pretty obvious that some sharpening is happening in the camera. The unsharpened image out of photoshop is considerably less sharp than the image that came straight out of the camera.

Removing the AA filter has not brought the Sony to the level of quality I was hoping for when compared to the Sigma. It is of course, still a fine camera but not as good as the Sigma where the Sigma is usable. The Nex cameras while not perfect are better at high iso and are much faster and more facile instruments.

好！

老兄用肖像模式拍些看看吧？

我的机器说是要到下周三左右才到呢，着急啊～～

确实，我用手机乱拍经常拍成这样，走动的人物超清晰，背景却模糊。

dp2m只要选择色彩模式为“肖像”，就可以轻而易举拍出高质量的人像作品，这是最令人鼓舞的，真是超值。【20120819_横田基地日米友好祭(Friendship Festival)】21_F-22 Raptor's Security

发错了，应该是楼上面那张的拍摄信息。

还好，没有大错。我对比了，这张除了文檔大小是8.87 MB以外，两张的其余内容前后期一样，看来摄影师是用的Custom后期批量出片的。

这种片太普通了吧，一般家庭摄影里多得是，很多摄友都会尝试这种拍摄手法，只要不是必须拍出一张清晰的，应该毫无压力。

这张照片不简单，理论上dp2m是不适合这类新闻题材的抢拍的，需要摇动镜头追踪目标拍摄。This photo was taken on August 15, 2012 in Bucheon-Si, Kyeongki-Do, KR, using a Sigma DP2 Merrill.
