I believe it's 24 stops.
True!
The human eye has an amazing range that digital technology has a long way to go still before it equals what our eyes can see.
Does anyone know how many stops of light our eyes can take in?
Cheers!

I personally can't afford to buy both systems to compare directly. Thanks for the link. Is there a downside to jamming in more sensels? Yes - probably: the smaller a well, the fewer photons it takes to saturate it. A saturated well determines the limit at which pixels turn white and hold no texture. This means that what you give up for sharper sensors is dynamic range and the ability to hold information in the highlights. Point & shoot cameras demonstrate this range limit often when highlights blow out. A less dense sensor sacrifices detail for increased headroom and dynamic range, even though it gains nothing in suppression of shadow noise. If people stated that they would prefer a less dense sensor in order to increase highlight headroom that would make sense, but they more often cite the fallacy that greater density increases shadow noise and poor low-light performance. Conclusion... If you are concerned with low light performance and shadow noise you have nothing to fear from higher resolution sensors. If you are concerned with increasing dynamic range then you may be justified in looking at cameras with sparser sensors. I am going to buy tomorrow. Used. It's between 5D, 1DSmk2('new' shutter, 5d x2 price), 5dmk2(5d x3 price). I'm confused, price is low on all three. I can buy both the 5d and 1dsm2 for same price as 5dm2. All have between 8000-20000 on shutter, 8k on the 1ds, replaced, so the rest have seen a lot of use, but looks okay).

Does that mean I'd be better off with 5D classic? Hard to say - technology has advanced since the 5D. If all things were equal, the 5D would be the choice (and it's still a great camera). But newer sensors have made some improvements - gapless microlenses and cleaner processing for example. Tom

Well it's not the same sensor is it? They don't take a slab of CMOS and cut it to size, they do however make film in large sheets and then cut it to size.

Nov 11, 2009 09:42 | #51 Panopeeper wrote in post #8993345 A larger sensor captures more light all together. This may not help when the pixels are small and viewed in 100%, but looking at a given presentation size, the result is better. The logic with film is simpler: to get a certain size of print, the larger film requires less magnification. chino79 wrote in post #8994554 Well it's not the same sensor is it? They don't take a slab of CMOS and cut it to size, they do however make film in large sheets and then cut it to size. A 21 mpix 35mm camera has different size photosites than a 40 mpix 6x6 didital back, now as far as a 4 year old mf back's DR performance, that was just a rash generalization. I was trying to make a point on the fact that with different generations of gear comes improvements in performance. So in theory a Large or Medium Format, should have the best DR in digital, provided that FF sensor's dont get ahead of the game. A larger piece of film captures more light too!

If you want the most dynamic range, yes! Of course that's probably the only thing the S5 does better than our current cameras but hey, the thread was "Which camera has the most dynamic range in your opinion" Mike

yogestee "my posts can be a little colourful" More info | The highest dynamic (called brightness range when I was shooting film) was Tri-X 320 4x5 rated at 250 ISO and pulled by 15% during develop,,developed in D-76.. I managed to get 7 1/2 stops.. Shot using a Linhof Technika/Schneider Symmar 150mm f/5.6.. Jurgen

The image circle covers a larger area due to the lens design and size, it does not make extra light Let's simplify it to the comparison between FF and APS-C cameras using the very same, FF lens. The lens projects an image with FF size, but the APS-C camera does not use the entire image. The area used by the APS-C camera has the same luminosity for both formats. Isn't it obvious, that the FF camera utilises more light, than the APS-C? If I take a light meter reading of a subject and it reads, ISO100 1/500th f5.6, it will not change if I use 35mm or Large format The result is, that the level of illumination of the film (or sensor) is the same; however, now we are talking about a larger surface, i.e. the same illumination level means more light.
