Meanwhile, here is another professional video camera head with 4K(3840×2160)/60p real time video out Lens control for IRIS and focus (Micro Four Thirds lens only) by Astro: http://www.astrodesign.co.jp/english/product/ah-4413_ap-4414_am-4412

I suggested to buy this cam for film university today, and our, well, mostly slightly uninformed technician, who makes decisions sadly, said: "we cant use it. global shutter produces trails" - you know, artifacts like when your lcd screen is too cold.

Now, he insists that this is true and that he knows it from some convention here in germany with many professionals. I found nothing of the sorts online. Can Anyone point me to any Info on this device he might have meant?

To me it just seems he makes stuff up. Thoughts?

How hard can it be to build a mount right in front of the sensor and sell the adapters to several other mounts for good money?;+)

@shian 3D printing is indeed a hidden revolution. The day will come when we will be even able to print out things like mounts that need to fit 1/100 mm (at least for proper focus mark matching). From my experience 3D printing is still fighting with 1/10 mm if you stay in the affordable hobby price class.

@Vitaliy_Kiselev I agree, it is expensive, and it is not really a field camera but I don't see why it wouldn't be used in studio broadcasting. Why I posted it? I think, I'd prefer the modular concept and the MFT sensor/mount.

@WhiteRabbit I think they mean the 1/1.25 inch sensor, which --I guess-- is based on the UDTV2 sensor by Aptina http://www.imagesensors.org/Past%20Workshops/2009%20Workshop/2009%20Papers/071_paper_nakamura_aptina_udtv.pdf

4.2 µm pixels, 4112x2168 effective pixels give us 17.3mmx9.1mm effective sensor size.

@johnbrawley

Do you expect to shoot with this camera in the near future?

hmmm why doesn t bm go for e-mount?

I am sure that with time they will :-)

No sample video 2 weeks before supposed launch???

@danyyyel, heavy emphasis on the word "supposed" at this point, I would think.

Considering there are only 3 stops that retains details and up to 5-6 stop max you can use, I don´t see the point of having 100 range of dynamic range. 10 is already very useful. I can see the point of having raw, 4k, global shutter, 13 stops, crystal clear zeiss, but that´s not going to dramatically improve your film quality. It´ll eventually save your life in some situation if you took bad take or whatever. But honestly 2k, rolling shutter, 10 stops, conversion prores 4:2:2 let you enough material to work with but it may indeed not save your life in some situation if you did a bad take.

What´s interesting with this camera IMO is that it allows filmakers who can´t afford high end camera to train with a cheaper one that offers almost everything and maybe help them to make up their mind with what 4k can offers in terms of possibility (like cropping and make some pan from a still shot or greatly help with 2d/3d compositing). It´s not a revolution, it just allows more possibilities and I am sure it is good for that.

Give me everyday a 1080p 13-14 stop DR camera to any 10 stops 4K camera. Sharpness is overrated. I read on a forum the other day someone saying something so true. He said that in 5 years when we will all have 4 k camera, everybody will be discussing about diffusion filters to soften the image like cinematographers have been doing for ages with film.

What do you think people will learn with more pixel??? As a photographer with a Nikon D800, in normal use the D800 does not bring me anything in normal size prints. Where it makes a difference compared to my 12 megapixel d300 is its DR. Blown out sky or heavily crushed shadows are always visible from 2 to 36 megapixel.

@danyy yel just not true all depends on screen size

@Ian_T No one really knows. John Brawley said that it will be lower than 12. It all depends on final tune.

Yes, when Brawley was questioned he said he thought it was lower than 12, he did not want to commit more than that.
