mosswings: This is an interesting deal because the RED's sensor is APS-H, 1/2 stop smaller than the D800's and about 1/2 stop larger than APS-C. Pixel pitch and resolution are not a factor here.
The really interesting thing about this sensor is that is is using 1) a much different balance in the CFA, increasing the signal to red and blue sensors, and more importantly it is oversampling - combining multiple images taken per final frame so as to reduce noise by averaging. That's what "temporal" noise reduction is.
Overall, my guess is that it's exploiting the fixed frame rates and lighting conditions of video and oversampling perhaps 6-8 captures per frame, which means that it can read out full-frame data from its sensor at over 400 frames/sec - 4 times that of the fastest still cameras.
This does NOT mean that the sensor used in the RED has employed some secret new bulk technology that improves on standard CMOS sensors; rather, it's probably ordinary CMOS with a very fast readout scheme.
Can't see what you gain by taking 8 samples per frame, you just get 8 lots of read noise (thus reduced dynamic range) and the same photon noise (assuming no gap between samples).
Wait, that assumes the level of light is the same, if you increase the light levels three stops then you will get a decrease in photon noise. Still not sure if this helps DR though.
Photato: Video not Professional.Chroma Resolution 480 x 540 pixels
What? They're encoding the video at 4:1:0? Or have you got your numbers wrong?
kinglau711: WOW not able to bring a single real innovation in two years !
Even incapable of adding a GPS, WIFI or a viewfinder as large as the 5D Mark III and 1DX.
When there's about 50 pro photographers crammed into the press room at a major sporting event I don't think WIFI is going to cut it, especially compared to the ease of plugging in a gigabit wifi jack straight into the camera.
zimarrio: Does anamorphic lenses still make sense in digital cameras?Isn't the image going to lose quality after up-sampling the pixels when converting to 2.35:1?
You do loose quality upsizing, but you're left with a 2556 x 1080 file. The preferred method is to downsize the vertical to give a 1920 x 810 (which you can letterbox to 1920 x 1080) file that will play on a regular HD tv / screen. That gives better quality than shooting in 16:9 and cropping to get a wider aspect ratio.
Kassra: Sigma is the only manufacturer placing pure photography above pure profit and not give in to silly market demands, and resists fads and gimmicks.
It appears Sigma has listened to all levels of feedback and improved on all fronts. New forms that are more functional tend to grow on people in time, and look more pleasing to the eye too.
THANK YOU Sigma and wish you success with it.
Whether the FOVEON sensor is a gimmick is open to debate but the body design definitely is!
jkoch2: Global shutter is nice. But, to be operative, a Blackmagic system requires considerably more scratch than the $3,000 price of the body.
Outstanding pre-orders now stand wat what multiple of inventory?
From the press release:
"The Blackmagic Production Camera 4K has everything customers need right out of the box including a built in SSD recorder, rechargeable battery and a large 5” LCD touchscreen"
So it can do 4K RAW out of the box. Which is more that you can say for the GH4. To be really useful you need a rig, but it offers more out of the box than the GH4.
chida: They should make mounts for Nikon and other lenses. Filmmakers like myself who have plenty of Nikon lenses, can use them on Blackmagic, and their marketshare also increases!
You can adapt Nikon lenses for the EF mount, but not vice versa, hence the EF mount make more sense, saving the cost of offering two options.
W4YNE 1: Canon 5d Mk4K possibly in the near future????
The only thing Canon will do with the next 5D is lock down the hardware so Magic Lantern can't offer RAW video - got to protect the more profitable Cinema EOS line!
Rooru S: Pretty amazing how much money Blackmagic has... Because this is an agressive marketing strategy and it seems either they have a lot of capital to sell thse things at a low price or they really know how to produce great stuff at a lower price
There's really not all that much *in* a mirrorless camera. Sensor + IO board + LCD screen + battery in a box with a hole in the front.
The way the thing is built (simple chassis, absolute minimum of physical buttons) means they can keep the cost right down.
Usee: That's the best move Sigma did so far...
...because the former Foveon also made interpolation for noise reduction......so, nothing is lost in this department - resolution wise...
...and they adressed what I mentioned years ago:
That the airy disc in in the "blue" region is substantially smaller, than that in the "red" region...
...thus the pixel size in the blue layer should be smaller than that in the red layer - which is the case now...
...and the problem, which I also hinted at, that it will become difficult for light rays with a greater angle of incidence, to penetrate in a proper way in narrow and deep pockets (esp. by conventional designed wide angle lenses) is also adressed...
...so, the color shift to the corners of the frame, which could be observed in the current Foveon cameras, will also be reduced, without the need to correct it in software.
And please don't forget to offer a far better software solution than SPP!
It took years......but finally they did listen.
Diffraction is not going to be a problem at 5 megapixels until you stop right down. The larger red and green pixels have a lot more to do with improving the bad medium and high ISO performance than they do with diffraction.
Ayoh: Looks like it might do video judging by the Mic and Speaker holes visible on the left side of the body
And the new zoom has built in stabilization too looking at the switches
Should be a really impressive piece of kit, and 1/2-1/3 the cost of the competition.
The 645D sensor is barely 1.2 times bigger vertically and 1.3 times bigger horizontally. So yes I do know how thin the DOF will be with an f/1.8 lens (which incidentally doesn't exist for the format), it will be like f/1.3 ~ f/1.5 on 135, something I'm very familiar with.
If you thought 150mm f/2.8 was shallow with the 645D you should try a 135 f/2 or 135 f/1.8 on 135...
Zvonimir Tosic: Tilting screen, same image processor and AF as the K-3 DSLR? Dual SD slots? Weather sealing too? Perhaps even video recording, using some fantastic MF glass?Sounds delicious. If they pull out video somehow, this will be awesome!
If you want high quality video, get a video camera. The "fantastic MF glass" wont offset the mangling that results from subsampling the 50MP sensor down to something that you can encode in realtime.
There are plenty of "fantastic" lenses for video.
ragmanjin: They've said in a bunch of interviews that their next MF should be mirrorless, I'm hoping that's what they're going to do. THAT would scare the pants off every other ff/mf manufacturer out there...medium format with the same quality as the latest-generation Phase/Hassy offerings at a size comparable to the D4 and D1X or even 5DIII and D800 — and a price less than the new 35mm "Hasselblad" single-lens translucent, nonetheless.
....Sorry, just drooled on the keyboard a little.On the other hand, if they pull the same "mirrorless" thing with the 645DII as they did with the K-01 (same mount and therefore size as before) I think they might miss a big opportunity. If Leica can break into the market so late with a limited line of lenses, there's no reason they shouldn't be able to change the mount to a 35mm-typical flange distance with adapters to provide compatibility to those with legacy glass.
Just my two cents.
Now if they could build a MF mirrorless camera that could also be used as a digital back...
It would not be better than the 5D2 for shallow depth of field, there aren't even any f/1.8 lenses available for the 645D, let alone the f/1.4, f/1.2 and f/1.0 lenses you can get for the 5D2
When it comes to shallow depth of field 35mm is king. Fast glass pretty much doesn't exist for larger formats so their depth of field potential goes unrealized.
DDWD10: I wish I could see a teardown for every new high-end camera, iFixIt-style.
@Heaven is for real
The Canon 5D mkII and 5D mkIII are radically different in terms of construction with the mkII being a proper metal chassis and the mkIII being plastic with metal panels.
Smeggypants: I went straight to the pics, thought the modern versions were cap and came back here and found out they were in IR. A goodidiea ruined. either use proper colour or do them black and white for an even better comparison.
Oh and dont' forget to stand in exactly the same spot next time.
Very poor 1/10
Demand your money back!
AshMills: Is it just me that thinks IR does not add anything whatsoever to these?
That's hard to say without seeing present day images photographed in the visible spectrum.
There's also the possibility that the images had more than one purpose, IR is useful for distinguishing between different types of vegetation, a lot of satellites carry IR cameras for environmental monitoring.
sebastian huvenaars: Imagine the new CEO of Ferrari opting to buy up some Toyota's, fit them with seat made of cherry wood and a ferrari badge and sell them for lunar amounts of money...
This is what happened to Hassy passed period lol, it would be comical if it wasn't so sad.
Ah well, no more of that :)
I'd quite happily buy a re-badged brand new Toyota for the price of a Hasselblad Lunar- £5300!
mgblack74: I guess getting sued by Nikon wasn't enough. Now it's Sony's turn.
@offertonhatter The buttons might be in the same place but the maximum aperture values (and probably the focal length, though the actual focal length of the PIXPRO is not stated) indicate this is not a rebadged Sony lens...
tornwald: I am betting this will be able to compete with the Zeiss Otus. For a lot less money
Many lenses are able to compete with the Zeiss Outs, that doesn't mean any of them will win.
