Viggo said:David Hull said:With regard to the 400k ISO, IMO the real question should be "where does the ability of the AF to work crap out?" Super high ISO isn't of much use if you can't focus clearly.
I've seen this comment by others also and one answer could be, and this goes for me, it's not about the pitch black use of it, it's about shutter speeds. I often use ISO 5000 outdoor in not too low light to get my 1/1000s-1/4000s shutters. When shooting sports indoors and you want some dof for example, it makes sense to have a very high iso. Have I ever needed above 51k on my 1dx, no, but I like to shoot with the widest of apertures.

3/ If Canon does not release a new camera with better DR, I'll switch to Nikon forever.
4/ Canon fanboy of 25 years (FD, EOS, EOS-digital systems + 20 lenses)
1/ No they haven't, they wiped the floor with Nikon sensors for years, now the seesaw is the other way. Heck for years Nikon said there was never any point to a FF sensor!
2/ Because taking the images that put food on the table is abut a lot more (a hell of a lot more) than one sensor metric. The difference in DR pales to insignificance when you need in focus images, for instance, ad Canon AF still beats the pants off Nikon AF, apart from that damn 1D MkIII mess up, which temporarily gave Nikon a sales boost.
3/ Bye, nobody cares, especially Canon. They have bean counters that work out how many people are expected to leave over any feature or non feature, you have been accounted for and ignored.
4/ So what? You don't owe Canon anything and they don't owe you anything. If more DR, or whatever you feel would serve you better by another manufacturer, is critical for your images get something else.
ok, guys, I should have said that Canon has been lagging behind Nikon/Sony in the last 5 years (a long time) or so in sensor DR. I have seen too many published articles bashing Canon sensor technology and am upset becuase I have invested thousands of dollars in Canon gears. It is a shame that even the 1DX has a sensor much worse than Nikon/Sony cameras half its price!
I vote to have you promoted Director of Canon USA Customer Service (**).

Or if you are nuts about shooting everything at ISO 50 or 100. But if you're that nuts about that, you should be using a D800 and a Zeiss lens...at least until Canon bring out their high MP camera (and even then you'll need a Zeiss lens).
Or, if you're really a purist, you'll insist on a 50 pound wooden tripod with 8x10 film plates with a donkey or two and an assistant to carry it all for you![]()
...but...but...but then you didn't do all the work yourself, so you can't truthfully do what those types do, and complain about having to hike 50 miles in the dark to the location while carrying said huge field camera with cast iron tripod on your shoulder!
LOL and speaking of that, "When the Banner Peak photo became famous, Harold loved telling everybody, 'I held Ansel's ass while he made that picture!'"

drjlo said:Rienzphotoz said:Tamron's VC or Canon IS will not help with people photography in dimly lit indoor situations ... coz people move
At say 50 mm focal length, with adults "trying" to pose and not move, what minimum shutter speed would be typically required for subject motion?
Looking over my shots, I actually got some very sharp photos at around 65 mm at 1/30th.
Some of the moderately blurred photos were for example 61 mm at 1/16 th ! Didn't even realize how slow shutter speed was due to trying to run after people. So in these situations, IS/VC would not have helped anyway?

another annoying note on the tamron is that the foot only have 1 hole for a lens this size i would have prefered a double hole for mounting the arca plate

JesseKorgemaa said:It most certainly won't come to the 1dx as its a different sensor. The C100/C300 share the same sensor and the technology for it was already built on the sensor, however it wasn't finished until implemented with the 70d.
This video should help you see its quality. https://vimeo.com/87006298

Khufu said:Has it ever been rumored for their to be prototypes in testing of what would essentially be a physical 1.6x crop of a FF sensor, allowing the ISO capabilities of the 6D/5D3 in, say, an EOS M or xxD body?
I'd love me an EOS M with 6-9 megapixels of low light goodness!
Thoughts?
Would this be stupid-expensive to develop? I can imagine the right advertising campaign could sell the concept of fewer pixels for low light, arty, shallow DoF shooting with the 22mm f/2 with results that're still 2-4x larger than necessary for Facebook![]()
I wasn't quoting with my reply, I was replying to the OP. Perhaps I should have quoted him in the first place, sorry for the misunderstanding.
StudentOfLight said:This is a simplified version of events...
1) A given lens gathers an amount of light (x) through it's image circle.
2) Diffuse light (a) is cropped away at the aperture
3) Then the camera body crops from circular image into a rectangular image thereby losing light(b).
Light reaching the sensor = (x-a-b)
Canon APS-C bodies, by virtue of their smaller sensor design crop away 61% of the light from a full frame lens, which the full frame sensor wouldn't have.
