Wow! Really F6.3 being marketed as a sports lens? Maybe on the planet Venus. Rarely is F6.3 enough to stop sports action.

Nice work! Essentially, Magic Lantern is able to recover closer to the 'sensor DR' - by mitigating the effects of downstream read noise probably introduced en route to the off-imaging-chip ADC in Canon architectures.
The extra 0.8EV 'highlight headroom' (or sorts) is interesting. Makes me wonder if something similar is going on with the Nikon D810 & the 36MP sensor in there. DxO data suggest they're able to map a higher signal off the imaging chip to the same Raw value at ISO 64 -- essentially like extending the effective full-well capacity of pixels at this ISO.
Very nice article, lots of effort to do that, most appreciated
Can these results be extrapolated to a 7D? I don't mean would a 7D be the same as these examples but would it have a similar ratio of improvement?
If so and this is all software based, makes me wonder when the (20.2MP guess) 7D2 makes an appearance and shows a similar improvement we will all be shouting praise be!!! and all 7D owners clamoring for an official software update
Well if there is a marked improvement it will be easy enough to test how it was/wasn't done, just find a tree
Really surprised this topic hasn't generated more interest.
Doesn't this show in real world terms just how easy, without changing any sensor tech, it would be for Canon to improve one of the most complained about aspects of their current sensor design?
Best Buy 'discontinued' the 5DII at least three times before the 5DIII was announced (and Canon didn't discontinue the 5DII until well after the launch of the 5DIII).
So I'd say this means nothing.
I can't imagine Canon doesn't read to some degree forums like this one especially. If they don't then shame on them. The people here are the 80/20 rule. The 20% of their market that comprises 80% of the base avid user. I would like to believe that Canon is wise enough to know how to produce a camera properly for the given target market. With a 2000-2500 body, they should darn sure know what the criteria are. And I believe folks like me and jrista are a big chuck of that market. Give the pros a reason to keep those white lenses on the sidelines of Saints games and whatnot. If Canon gets too over zealous with pop culture features, the artists out there will continue their outward migration.
The 5D3 was a killer piece. I expect the 7DX to keep within that pattern and deliver strong fundamentals that will be a harbinger of the next gen FF pro bodies. They need a Sony/Nikon wrecker. If there is any wisdom left at Canon, that's precisely what they plan to deliver through 2015
I really don't see the benefits of adding a touch screen. I prefer the tactile feedback from a button or a dial. Would a touch screen still work flawlessly on a cold winter day when it's snowing and the gloves are on? Would it work if I was out shooting in the rain?
No wifi or touch screen? Bummer. All future canon prosumer cameras should have BOTH wifi and touch screens IMHO.
Darn it! You beat me to it!QuoteEOS-1 style top plate
No mode dial?
Regardless, I expect Canon to drain my bank account just like they always do. Something they are very very good at!
I'm still using my 10-year-old and 9-year-old Canon dSLRs because none of the updates since have been particularly interesting. I have several friends with Canon dSLRs, and they are similar. One is still using his 40D, one is still using his Rebel XT, one is still using his T3i. I'm still using a 20D, 5D and a T2i at work. I've watched every Canon release carefully in the last 10+ years.
