Canon has great ISO performance, but they've been pretty behind in dynamic range for a while. Even the sensors in their cinema stuff have the same problems. Sony might be worse at colour/coming up with a system, but they've certainly got a tech advantage.

I've posted this a few times before, but patents were filed for tech that essentially does dual ISO, except for each photo cell instead of alternate scanlines as Magic Lantern does. So a solution is being worked on. The problem now is the wait for this to get actually implemented. I'd figure one of the next FF iterations would come with this. If at all.

Then again, they also have patents for a Foveon style sensor, which everyone says is deadlocked with some actual Foveon patent, which is due to expire. Except no one seems to be able to point out which one it is and when exactly it's supposed to expire.

Possible. Maybe others have been doing this, too. I find it curious that others already get 14 and something stops of range, where as Canon essentially needs to do this dual ISO business to get the same DR. Also, given various graphs seen at sites like DXO et al, that other brands lose DR pretty fast and getting into and below Canon territory, when going into high ISO, it kind of supports the idea that everyone except Canon's doing it.

Aside from the gripes about DR, Canon's high ISO is pretty nice considering how it favors the f/4 zooms. No need to splurge out on a 24-70 or 70-200 2.8 when the 24-105 or 70-200 f4 and an ISO bump does just fine for a good deal less money. Pros don't care of course.

Every Canon camera except for the C300 loses tons of DR at the higher ISO's.

Somehow they made a magic camera that keeps 12 stops no matter what ISO you're at.

I also doubt the other manufacturers are doing dual ISO. I could kind of see it with full frame sensors since you have more pixels to work with and can debayer/resample without losing much quality, but the Blackmagic Cinema Camera has about as much DR as a D800 and it's sensor is around m4/3 sized.

Canon's lose DR at high ISO, but I think what he was saying is that they lose it slower than the other sensors - The Sony and Toshiba sensors AFAIK , have a big DR advantage at base ISO, but as it goes up, they equalize with the Canon sensors, then drop below them at high ISOs.

DXOMark - Check the 1dx vs DF , or 6d vs d800 - once you get to 1600/3200, the Canon sensors have higher dynamic range than the Sonys. I was wrong on the crops though, the 70D becomes more in line with the Toshiba d7100 sensor, but doesn't ever go above it (Just checked)

Edit: Grain of salt as with all DXO robot measurements as to how much this actually means.

Edit2: And it's not a huge difference - .3-1 stop , but the way the Sony & Toshiba sensors "fall off a cliff" and steeply drop back in line with the Canons after a certain point, but have such a huge 2.5-3.5 stop advantage at low ISO, suggests that whatever they are doing to get that advantage, is not sustainable at high ISO. Whether that's because they're doing some kind of dual ISO trick like ML does for Canon or not, who knows, it's their secret sauce.

In this case, I mean dual amplification of the same pixel. That's what Canon's gunning for, running two different amplification circuits on the same photosite. I wouldn't be surprised if the other manufacturers already do something like this. I doubt that the sensors work that differently between the manufacturers that there's two stops, i.e. 4x, of a difference just like that.

That said, I'm surprised that Canon's not fudging some mosaiced dual ISO on their 70D sensor, since each pixel is two subpixels.

What the other dude said, the Sony/Nikon sensors crush the Canons in DR up until about 3200 where they even out and the Canon's pull away slightly.

If you look at the chart, you may notice that the Sony sensors lose a stop of DR for every stop of sensitivity you add. The reason being, and I'm paraphrasing heavily here, is that the Sony EXMOR sensors are a pseudo iso-less design, as in they don't see much electrical amplification until you crank up the ISO to a certain amount. So on Canon it's better to bump the ISO in-camera than in post, a D600 it doesn't matter as much.

I won't try and defend Canon's laughable sensor update cycle, but I will say that different camera have different strengths. For me I decided to go Canon for the high ISO, speed, AF, lenses, video, etc. I honestly spend most of my time shooting digital at 1600 and higher.

I can't speak for their mail-in service, but the one time I went to an actual Nikon service depot (I was fortunate enough to live like 20 minutes from one), it was great. Dude in front of me was bringing his banged-up 300/2.8 in, and the front desk lady asked if he'd done some warranty-voiding mod that apparently lets you use TCs it wasn't designed for, and that it was important that she tell him, so that if he had, she could write down that that part of the lens was damaged in whatever accident he had, so the service guys wouldn't kick it back as voided-warranty.

They then proceeded to repair my in-several-pieces SB600, obvious drop damage since there was still some concrete dust embedded in a corner, under warranty.

That is pretty awesome of them - I was really worried they were going to bump this back as warranty void because I know the USM mechanisms on a lot of lenses get damaged in drops, and the symptoms are exactly what I was experiencing (focus ring hanging up/sticking at a certain point) - It seems that everyone has that happen to their 50/1.4 at some point. So I was thrilled when they replaced it no questions.

I dunno, maybe I'm missing something but the DR thing seems to be kind of exaggerated. Like, I can post photos of random landscapes and portraits and its hard to distinguish which camera did what. The benefit seems to be recovering detail in shadows, which is cool I guess, but unless you're really underexposing and pulling shadows up, the 5d III does pretty good.

I would like more megapixels though, I really appreciate the direction the d800 took cameras, and im not against pushing sensors (including DR) but I havent seen very many examples where the d800 "blows away" canons images based on DR.

Can someone post an example of why I'm wrong? I feel like im missing something.

More stops is more options in editing and you get to have better results if you love shooting directly into the sun/less likely to clip highlights in general. That being said, if you actually manage to get the shot right the first time, you probably don't need those extra 2 stops anyway. It'd be neat if digital cameras can get closer to real life DR than film ever did, but right now it's not quite where film negative was, mostly only when it comes to dealing with highlights.

When Sony made their F35 digital cinema camera they specifically programmed the sensor to dedicate extra DR to the top end, just to emulate how film rolled off its highlights. It came at the cost of bottom end/darker area performance, though.

For finished photos people post on the net you'll find stuff that looks great from all sorts of cameras that don't have amazing sensors—you don't have to have the best to make a good photo. Where you'll really notice the difference is if you're actually using the camera and doing post processing yourself. An example would be HDR shots, where the sky is super bright and the landscape is relatively very dim. With the D800's massive shadow detail you can expose for the highlights and bring up the shadows in post instead of doing several exposures. And when you actually see the shadows compared it's a very obvious difference. This Fred Miranda article has a good example: http://www.fredmiranda.com/5DIII-D800/index_controlled-tests.html

I've read somewhere that part of the noise on Canon is that the ADC is supposedly in the DIGIC chip (external ADC), where as Nikon on at least the D800 has it sitting on the sensor (internal ADC). External ADCs apparently introduce way more noise via interference on the signal path from the sensor to the DIGIC chip. Supposedly Canon's working on internal ADCs, too, now, going from various patents. Of course, it's just a matter of years until we see some fruits of that labor. :shobon:

Need some general advice.

If you wanted to go full frame and had nothing invested in a current system, what would you recommend in the sub 2000 market? I would theoretically be dropping around 3000ish total after tax refunds so while I would love something like a 5d mkiii, that would eat up the while budget before lenses. Would really like weather dealing as well as I would be using this for outdoor gigs.

I have an X100 which I use all the time and am happy with, and have invested in the NEX system with a few lenses as well as old manual glass but I am a) not happy with how stagnant NEX has gotten (I was about ready to get an NEX-7 but I just question how fast that market seems to be moving with bodies but not lenses) b) would like something for better autofocus and c) would love to make a move towards full frame. Again, I am not really tied to a system.

All of my camera research since I got interested in photography in 2011 has been on mirrorless stuff so I have just begun looking at DSLRs. Maybe something like a d600?

eBay offers 100% buyer protection. I've used it and I trust them, it might just take some time if there's a problem because they want you to work it out with the seller if you can. That said, most stuff I've got from ebay was problem free and the one problem I did have wasn't really the sellers fault but they ended up paying to fix it anyway. I don't know how KEH works it but I know that you can haggle prices on used gear with Adorama if you get them on the phone. KEH might be the same.

One point in favour of KEH is the big discount you'll get on combined shipping if you decide to buy a bunch of stuff at once from them. Any random eBay seller might or might not have the other things you're looking for (lenses, to spell out the obvious example). If the eBay seller you find has a great price, cool, but if they don't have the other things you're looking for then combined shipping simply isn't possible whereas a big order from KEH will get you at least that discount, plus anything else you can negotiate with them. Again, probably not worth $250 unless you're really going to town with ton different things.
