I would, if I were familiar with maths and physycs, but unfortunately I'm not. Apart from the logical statement that moving a small mass requires less energy than moving a bigger one, I can't produce mathematical evidence of this. But I think the maximum 'achievable' frame rate, disregarding processing speed, could be higher than the maximum 'convenient' (or 'applicative') frame rate since, as you mention yourself, durability kicks in, together with image quality degradation due to vibration. I think a 'theoretical' burst at 25 fps would possibly introduce an unacceptable amount of vibration blur.[...achieving a speed equal or even better than the 1Dx in an APS-C-sized DSLR represent a much smaller engeneering effort than that required for FF since the mass of moving parts (mirror and shutter) involved is approx 1/3 of a FF camera, so much less inertia and, consequently, less energy required.Would anyone familiar with mirror flip physics care to speculate on what the maximum achievable (and durable)frame rate might be? (Speaking APS-C size mechanics only, disregarding processing speed )
Thanks a lot!do the Magic Guys have to begin again from scratch every time they 'assault' a new model or can the previous work be transferred, in the form of pieces of code or at least expertise, from one camera to another?
No, the basic ML codebase stays the same and is very mature by now - i.e. integrating with Canon DryOS as far as setting props and memory allocation is concerned. The 7d1 has a unique catch though which might also apply to the 7d2: real dual digic-processing (and not just offloading the af to a digic).
That's the reason the 7d1 port didn't get started for some years as it wouldn't boot at all, and even now some features don't work at all. In general, my estimation is one year from "Hello World" on a newer camera to a release which has been tested enough so everything works w/o hiccups. *If* a maintainer for the camera is found, and that's not very likely since it's an unpaid job requiring months of man-work. Btw the 6d is unmaintained right now (but somehow working), and so is the 100d (not working at all).
Pity about Fred's cheating and Neymar dirty play though.Indeed!
Wonder just how many togs were at that game, the entire pitch seemed to be surrounded by them. How do they all earn a living with such saturation?Well, it's the FIFA World Cup... Rather, how do they not intertwist and tangle with each other, clumped and compressed as they are in such a tiny space! Looking at them it seems impossible not to bump and push others as they follow the action.
...IMO, the most critical thing that absolutely must be present is an appreciable increase in IQ / reduced noise.Welcome to CR! I wholeheartedly agree, and voted 'other'. The only specs that matter to me are related to IQ and FPS, so my wishlist is limited to:
...we need better noise performance at reasonable ISO's from 1000+ which is commonly needed for wildlife shooting.
... I will be ecstatic if there is increased IQ / reduced noise.
...If, on top of an IQ increase, they could squeeze a few more MP in, I would not complain.
Knowing Canon, they will take great care not to deliver a "mini 1dx" at 1/3 of the price that even works better for wildlife in good light because of the gain in reach.I hope and fear at the same time that if Canon deliver a true mini 1Dx, it will be priced around 1/2 of the current 1Dx price, which means approx as much as the 5DIII at release date. At this price tag it wouldn't eat away 1Dx sales by much.
At my own risk, let me add - and let the bashing begin! - that I'd be happy to see fewer and better MP than the 7D along with FPS equal or higher than the 1Dx.
To me, more pixels means better image quality (yes, including noise performance)
One of the main reasons that I use APS-C is that they are smaller and lighter than Full Frame cameras. Why would I want a gripped body that is larger and heavier than a 5D3 Makes no sense to me, therefore a Deal Breaker..
I cannot see how the body size has any effect on the IQ but does the bigger battery allow the larger telephoto lenses to move faster? Would a battery grip have the same effect?
If this is in a 1D body with built in battery grip, I can see a lot of enthusiasts disappointed. When the 80D or 90D comes out, they'll say that is what the 7D2 should have been.
Agreed. After 5 years it has to be something exciting. The same has happened with the 1Ds3/1D4 to 1Dx and 5D2 to 5D3 transitions, both noteworthy improvements. A 5-year interval between releases was a loooong time even during the film age.The EOS-1 ran from 1989 to 1994 (5 years) followed by the EOS1-n which ran till 2000 (6 years) followed by the EOS 1-V which I believe you can still buy (14 years). The venerable Canon A1 ran from 1978-1985. The legendary EOS-3 had a huge lifespan, 1998-2007.
As the dust has settled after the initial decade of the digital revolution, we'll continue to see just incremental improvements and longer lives between updates. Personally I find this both refreshing and irrationally irritating.
not a single source who has something solid to say?
even the NSA has more leaks...
Hmm...maybe the NSA should hire some Canon security execs to plug their holes... ;P
Hoping for something exciting!
If it were only minor incremental improvements, they would no be field testing prototypes or pre-production models at the world cup.... even the 70D with DPAF did not get a "public field test".....
