Guest Ebrahim Saadawi Posted July 16, 2014 Share Posted July 16, 2014 They dedicated the second half of the review for the video aspect, and made a little production using the camera. Great review. It seems the camera is no good for video. It has aliasing/moire, bad manual exposure controls, bad audio, bad low-light perofrmance (weird, as it's better than the A7s for lowlight stills) and a very heavily compressed 17mpbs h.264 codec. I also think the sensor is not large enough to give much of an aesthetic advantage over fullframe, that would justify the 5K$ price over a good fullframe video DSLR like a 5D or D810. Interesting camera though. Quote Link to comment Share on other sites More sharing options...
Nikkor Posted July 16, 2014 Share Posted July 16, 2014 And the video comes from a fullframe crop area (needs confirmation), and even if it's not the DOF bla bla is bullshit because the sensor is 44cm wide, that's almost the same as FF.

The weird is the low-light performance. The sensor seems to be incredibly sensitive to light. Better than the A7S at 200.000 ISO. The results are truly incredible. It sees in the night. How can you output a noisy 3200 ISO video from that sensor? Must be some horrible pentax handling of the sensor output. Quote Link to comment Share on other sites More sharing options...

Must be some horrible pentax handling of the sensor output. Because it skips lines, probably 3 lines, so you will percieve several times more noise in video as you will percieve on a still picture when observed at the same size.

leeys Posted July 16, 2014 Share Posted July 16, 2014 The sensor is larger, and given the state of MF sensors, it's probably half a decade behind everyone else in terms of speed. In fact this is the first MF sensor that has good high ISO capability - many MF sensors were optimised for use at ISO 50-200. In fact the switch from CCD to CMOS probably happened much later too. This sensor is much better because it's a Sony sensor, hence the high ISO performance and the ability to do video. MF is such a small market now, so don't be surprised if progress in this area is slow. Quote Link to comment Share on other sites More sharing options...
richg101 Posted July 16, 2014 Share Posted July 16, 2014 the 44mm sensor width is 12mm less wide than true 645 ( which is 56mm). that's the same reduction in width that we get between full frame and aps-c. The sensor is closer to full frame than it is to medium format. rubbish I'd hazard a guess and say the A7R and high quality full frame glass will out perform this with its mediocre pentax glass available in this mount. The marginal sensor size and pixel number increase is pointless if you cant fit lenses capable of delivering such resolutions. Quote Link to comment Share on other sites More sharing options...

You can fit all your hasselblad stuff on it, you loose AF but lol @ MF AF. Anyway, once the MF speedbooster comes out the A7R/S will be a Leica and a Medium Format camera.

JohnBarlow Posted July 16, 2014 Share Posted July 16, 2014 Anyway, once the MF speedbooster comes out the A7R/S will be a Leica and a Medium Format camera. Bring it on! We need 1.5x FF sensor width don't we? :P Quote Link to comment Share on other sites More sharing options...
