"This is an extremely exciting camera and its been amazing to work on. Our
original Blackmagic Cinema Camera was small, but this new model is so much
smaller than the original, we almost cannot believe it features very similar
image quality," said Grant Petty, CEO, Blackmagic Design. "
Cinema Camera拍raw比神马5d3,GH3强太多了。看下面的比较

Pocket Cinema Camera最强的是用微四三的头,还只卖$995.

看论坛上有人说为什么这个东东比GH3的video好
"1. Cheaper than the GH3
2. Records 1080p 422 10bit opposed to the GH3′s 1080p 420 8bit. So much
better color sampling is to be expected from the Blackmagic, making it
better for VFX and Color grading in Resolve.
3. 13 Stops of Dynamic range, which is the exact same as the Arri Alexa, a
cinema camera that was used to shoot Life of Pi, Skyfall, and Zero Dark
Thirty.
4. Ability to record in edit friendly 422 Prores HQ at 220mps (opposed to
the GH3′s MP4 Intra Frame 72mps), or shoot in compressed lossless CinemaDNG
RAW files… 1080p compressed lossless RAW in a $1,000 dollar camera is
groundbreaking.
5. The firmware is more suitable for video, with proper peaking, zebras, and
metadeta entry… and it comes with Devinci Resolve Light…
Unless you absolutely need 60fps, than hands down the BMPCC beats the GH3 in
terms of video.. But if you need a hybrid camera, the Gh3 is still the best
option."

但是GH3有over sampling,BMP没有
至于13 stops,如果GH3 sensor和em5是一样的话,
em5的sensor downsample 到2M以后的dr也是13 stop

BMCC用不着over sampling。BMCC的芯片是为film设计的,总像素和1920x1080相当。拍
video每个像素都用上了。
DSLR和革命机的芯片是为照相优化的。除GH2和GH3,都没over sampling。如果芯片有
6000x4000的分辨率,拍1080p时只用到~2000x1000线,也就是芯片1/12的面积。即便
GH2的over sampling相当于4个像素合一,1080p也只占4608x3456像素的50%。
BMCC最大的优势是拍raw时的Dynamic Range。就像DSLR和革命机拍raw和拍jpeg的区别
,虽然芯片本身DR够好,但在相机内直接转jpeg就丢了两档以上的DR。
而film camera和camcorder的最大的区别就是DR。BMCC出来的是film的效果,而一般
DSLR出来的是video的效果。BMCC的DR至少和production film camera差不多。

除非它不是像素马赛克,就是x3,否则无论如何比不上over sampling.
按照e-m5的表现,4x down sample也有12.7 stop的DR
BMP的亮点在于raw,GH3的raw还没hack出来。
但是话说回来,这东西不上附件,多少人用得起raw?
上了附件,它的卖点pocket就没意义了。
