PMW-200 announcement july 26, 1/2" sensor

Some of those rumored specs look pretty sweet, especially 4:2:2, 1/2 inch sensor and 5.1 lb weight. I guess we will know more on 7/26.

14x zoom? lame! HPX250/22x and XF300/18x. i love my ex1 but if this is supposed to be the upgrade im not too excited. i was hoping for a lot more. hope these specs are wrong.

I love the 14x lens on the EX1: mechanical iris with f/stops on the lens, not some lame mini-dial; mechanical focus ring with repeatable focus points and hard stops, not a magic ring that rotates forever. I've been hoping Sony wouldn't go the dumbed down route as on the Canon XF series or the Panasonics which have these enormous zoom ratios and a correspondingly over-sized footprint.
 
has anyone been able to determine if this is a 1 chip or 3 chip sensor?

EDIT: just found it. 3-1/2".

The 14x zoom is a result of the 1/2" chips. Someone who understands lenses to chip sizes can explain why, but there's a physical reason why Sony could only go to 14x. I'll take the reduced zoom capability to gain the benefits of a larger chip set anytime.

50mbps, 4:2:2 is a big reason to celebrate. That, and the better low light ability, cleaner image and depth of field available with the 1/2" chipset. I expect the image from the PMW200 to be noticeably superior to the EX1R/3, certainly in post production.
 
It's worth noting the PMW-200 will have timecode and genlock, features previously reserved for the EX3.

Also, the wifi module and 50mbit codec may mean wireless video transmission is possible.
 
Looks like a pretty nice cam. Anyone know why these cams don't have the 1080p60 capability yet? If they could make it simply a firmware update on a camera like the Panasonic AC160a, how could the other pricier cameras like this and HPX250 not yet have that option? Any other cams under $8k with that capability? Could this be a firmware update for others too in the future for this camera?

Also, do any of these sony cameras have flash banding compensation?
 
I can't wait to handle this camera. Although the hpx250 is the better value, I want check out the Sony with its mechanical manual focus, iris ring, 1/2" sensors and see how well the 50mbs codec holds up and cuts with Edius.
 
So wait, I can't figure this out anywhere. Are the 3 1/2" sensors any different from the 3 1/2" sensors on it's predecessor the EX1? I certainly hope so. The EX1 is a great camera for what it is especially with the lens, but it gets harder and harder to justify using with the old high noise sensors, just give me a EX1r with a cropped sensor from a FS100 in it and I'll be fine! After a 4+ year wait really hope they have released this with an updated sensor block!!!

PS. I also agree that not including 1080p60 at this price range 2013 is pretty lame.

Small sensors = small pixels = noisy
Small sensors = small lenses with huge zoom range and 'easy to focus' DOF

I dont think the FS chip is actually any better per unit of cross sectional area - probably worse considering its single chip
 
Thank you for all the info on this camera. Im a bit confused about there not being much possible improvement to the sensor and size being the main issue. I remember reading this article a while ago where Barry green goes off about sensor size vs performance, but maybe that's what somebody was referring to about the image processing ?

"Noise


The EX1/EX3 have been hailed as being quite low-noise. The HPX300 (especially after the firmware update) was competitive, but not quite as clean (and when the black speckles would hit, it would indeed be noisier than an EX1 or EX3). So, how about now?


Now, it's a different story. The HPX370 is cleaner. Period. In 1080/24p mode (which I spent most of my time in) it's noticeably cleaner than the EX3. Not dramatically, but noticeably. It was easy to see the difference on the monitor, and when I pulled in the chart footage and split-screened it and magnified it, yeah, the HPX370 is cleaner than the EX3.









Low Light Performance


You'd think that with more-sensitive chips that are lower-noise, the HPX370 would be a better low-light performer, right? Well, it is. But there's more to it (there's always more to it, isn't there?) At equivalent gain levels, the HPX370 shows less noise and more brightness (as you can see in the sample video above.) But, because the HPX370 is about a half-stop more sensitive (in 1080p mode) you can actually use -3dB of gain on the HPX370, versus 0dB on the EX3, and have the same level of brightness but a substantially lower level of noise..."
 
Finally, one of the engineering staff steps forward and offers a suggestion.ENGINEERHow about if we make our 1/3" chipset outperform their 1/2” chips?​
