EOS Bodies / Re: A Sony & Canon Sensor Partnership Mentioned Again [CR1]

The site has them listed as Nikon, but I wonder if it is someone else.

It's a common misconception that you'd need a fab to make a sensor. You only need to provide the specs to a contractor. Nikon has always either bought 3rd party sensors or used their owns, depending on what is more convenient. OTOH having a dedicted line of sensor manufacture means you're stuck with it, can't pay it off with other jobs - all eggs in one basket.

I thought about that, but Canon's size is important.
Compare that size to the volume a production line of your average contract foundry can handle. Imaging sensors aren't that much combined area compared to more mainstream applications - while individually large their total number keeps the amount of wafers to be processed in check.

No, I'd still say it's fantastic - the 1/500 sync that is.

Well, while the D8x0 officially only goes to 1/320 a fast trigger also allows for 1/400 - almost there. Or up to 1/640 in crop mode :)

(wait, what ergonomics? it's a box with buttons!).

It's a box with a LANC input. Which means the controls are taylored to my rig (and there is less dead weight to move around).

I pointed out on one set that the 'DoP' was crossing the line.   They replied that they thought they had been perfectly polite.

At least it's only a narrative violation, put him in the grips boots and someone's head might end up right on the mark...

I am wondering when image processing softwares (LR, DXO, C1 etc.)  will start using GPU for image processing .
For C1 that would be quite a while ago with continuing improvemts over the recent years/releases.

This rumor seems farfetched, though.  If Canon could create a self contained camera that could continuously record RAW and compressed images at 30fps on a global shutter, it would have a huge impact on both the video and photography markets.  Nothing comes close right now.  The 1DC is a pale imitation since it can only record non-continuous 12fps RAW and 24fps compressed at APS-H crop on a non-global shutter.

The Dragon records 6K at 100fps, or extrapolated to 8k and a 3:2 aspect ratio still 40fps at full resolution. Or the rumored 52MP at 30fps. Global shutter included,the target audience isn't to fond of yello (behind the lens at least).
Or in the more consumer orientated segment you get 6700MP/s capacity, enough to go through 8K at >120fps, in a package smaller then the 1-series.

For raw storage you'd need a breakout to an SSD-raid though.

Can you do motion blur video that way?
In CGI it worked as an emergency kludge when rendertime for real motion blur wasn't available. Well sometimes, as the motion vectors mustn't change during the interpolation period, i.e. it falls apart for motions that contain a circular component or acceleration.

The whole still from motion picture-idea has problems on a higher level though: the visual language is different.


BUT I do not know how to compare to Camera Flash 58m./ 190' @ ISO = 100----Yes? How many of 580 EX  to be equal 500 Wats Power of Phottix Indra 500TTL ?

The easiest way to compare lights would use the guide numbers you get when using the strobe with a specific reflector. For example Profotos Magnum reflector paired with the 500Ws B1 gives you a guide number of 45@2m(studio lights are often rated at 2m or 6 ft, its more representative of real world useage - and the inverse square law doesn't work at such small distances when you use anything but a bare flash as it assumes a point source), or 90m. Which doesn't sound like much of a gain, thats because the reflector covers a wider area, but gives you a comparison for a set distance. (The narrow beam would have a gn of 90@2m or 180m, but I'm not aware of such a reflector for the Bowens mount while one of the Bowens tele-reflectors should perform in about the same ballpark as the Magnum).

That changes when you use some sort of additional light shaping, the guide numbers become meaningless and only the energy counts. If you'd take a speedlight apart and look at the parts used you can calculate that they store somewhere from 40-80Ws, depending on the model. Add the longer recycle times and tendency to overheat and you have an idea how many flashguns you'd need in that case.

Lighting / Re: Fast firing units?

I'm just trying to think outside the box on how to achieve better shots from motorsports events at night,

A B4 gives you the most latitude, with the NBR and BDs or some cinefoil keeping light pollution at bay.
The Move1200L would be almost as fast but lighter.
Now making use of the strobes w/o killing the mood requires some thought - right after you found out what you're allowed to do and what would be a bad idea.

It's hard to do full read out of a sensor with tons of MP though. The A7S has only 10MP for instance.

The NX1 reads it's 28MP at 240fps - even with 52M dual pixels that would allow for 60fps, not bad and obviously within the realm of the possible. Or, if you limit phase detection to a really dense (like 750*500) grid of cross type sensors, you'd get 4k/LV/FPAF at up to 120fps.

The closest resolutions based on 1920 multiples would be 9600 x 6400 which amounts to 61.4MP or 7680 x 5120 which are just 39.3MP. Another half way decent resolution would be 8640 x 5760 which amounts to 49.8MP. But why has it to be such a silly number like 52MP? I don't get this.
If you fill a 135 sized sensor with the pixels of the 70D/7D2 you get about 52MP.
Multiples of 1920 are only beneficial if you can't read out the whole sensor - i.e. if you have to bin sensor cells. Considering that binning only increases the amount of collected light but leads to a lower color sampling density then a full readout the other option would be preferable.

That will be of great benefit to the <4% of my shots which use flash.

Well, some consider shutter count a sensible metric - taping down the button will make you great really fast.
OTOH flash wins hands down in terms of income generated. Followed by the combination movie lighting and solid stands. To sad that getting things right the first time doesn't create impressive file numbers...can't have everything after all.

For me, 'everyday shooting/viewing' doesn't comprise tripod mounted static subjects cropped to 100%.  If that's your usual method/subject, then bravo – your results have validity as far as comparing teleconverters vs. pixel interpolation for increased resolution, which is certainly not the topic at hand.

Once you understand that this topic is about a high resolution camera and how flash photography works you'll realize why this is relevant for everyday usage.
That's even if we disregard the quality of the average column stand.

On my "flawed" normalizing:
1) Would you agree that a photographer should frame the subject as they intend to print it?
2) Should photographers use different composition rules when shooting on Full frame than they do when shooting APS-C? (i.e. Should Full frame users only frame their images in the tiny APS-C-equivalent portion of the frame?)
For this comparison you should frame as if both cameras had the same sensor format as the goal is to get an impression of how a full frame sensor with higher pixel density would perform.
Framing as intended to print implies different magnifications - leading to a massively oversized picture for the uncropped 4.7µ-Sensor. Your option 1 introduces an error of about the magnitude you would have between a 5D3 and the ancient 20D/30D.
