I think CR guy knows more than he's reporting. C'mon Craig, tell us something more!

EOS Bodies / Re: Mirror flip speed limit?
« on: June 14, 2014, 01:09:44 PM »
[...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  ;) )
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.

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).
Thanks a lot!

EOS Bodies - For Stills / Re: Mea Culpa! - The World Cup in Brazil

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.

...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.
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:

1-2 stops better high ISO performance over the 7D (even at the expense of resolution if necessary), and

12-16 FPS (yes, equal or better than the 1Dx).

Before you label me as heretic, I would like to underline that 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. This is entirely possible, and concern about possibly eating the flagship's sales is BS: I imagine a lot of 1Dx owners buying a 7DII to complement their flagship. Plus, amateurs like me, who cannot afford (or justify) the financial effort for a 1Dx and related big white glass, could finally deal seriously with sports and wildlife for less than half the cost of FF. In addition, should Canon lose a bunch of 1Dx sales, that would be largely compensated by selling other Canon gear in the form of 7DII.

On a side note, the high MP option of APS-C is already here: it's called 70D, and at this point, given the turnover of the xxD line, the 80D is not even so far away after all.

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.

Whatever comes, I hope all the hard work carried out by the ML guys on the 7D will be in some way profitable for the 7DII firmware hack, too. You're quite The Expert among CR members on this matter, so please excuse my ignorance, but I'm curous and have to ask: 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?

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)

At base ISO or low ISO settings yes. At high ISOs, I respectfully disagree. There's a reason the 1Dx has the best (to my eye) IQ of all the DSLRs available to date (yes, better than any Nikon I think): its 18 MP FF sensor. And there's a reason why Canon developed a prototype sensor with photosites 7.5 times larger than the 1Dx: to capture quality video in candlelight (candledrkness sounds better, though). Don't know if you remember, but check these:

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 used to think the same.

Lately, I'm reconsidering my preferences due to the many valid reasons voiced by other CR members in the above linked (and other) threads; not that those of the ungripped body camp aren't valid reasons, either. At present I'm 50/50, both options display advantages and disadvantages. So it seems I won't be disappointed in any case.

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. Overoptimism on my side? Maybe, but I don't think so. I'm awaiting for this baby weanling unicorn to finally deploy its wings, come on!!!

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?


Short answer: yes and yes (with 2 batteries).

Note that if you put 2 x LP-E6 batteries in the grip, the available power (wattage, i.e. voltage x current) is still lower than a single  LP-E4N battery, but the difference is not big enough to expect a significant difference in focusing speed.

Check this long thread, a lot of what we are talking here has been already extensively discussed there:

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.

Oops! You beat me for a couple of minutes... As you said, I would have been disappointed in the past, but honestly I must say I'm changing my mind as time passes, despite what I had said in prevous discussions. Anyway, the assumptive departure of the mode dial only suggests a higher chance for an integrated battery grip, I can't think of a valid reason for a non-gripped body not to sport an EOS 1-type top plate.

Pop-up flash: I like, IR flash triggering should be there in this case, but radio? Having both options would be really great.

So, if this CR1 is true, should we expect an integrated grip body? I wouldn't dislike, though I've always been saying I'd prefer a non-gripped 7DII. Actually, the more I think about this (also re-reading some old threads on the topic), the more I appreciate the gripped option. The 1-style top plate points towards an integrated grip.

On a side note, this time I resolved not to be an early adopter, but really I don't know if I'll resist...

Can't wait for more reliable rumors!

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.

Exactly. Electro Optical System was already a mature tech in the '90, electronics (exposure, autofocus) were widely adopted by practically all camera manufacturers and implemented on all high-end models, so the lifespan of cameras settled around 5 - 6 years which, at that time (i.e. no canonrumors.com  ::)), seemed to me even longer than today. Then digital kicked in around the beginning of the millennium and R&D on film cameras stopped, so there's no real significance to make a lifespan comparison with cameras that have not been, and presumably will never be, upgraded or replaced.

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.

How true!!! I really like your last sentence a lot because it perfectly defines how I feel, I couldn't express myself better. "Irrationally irritating": pwp, you're a poet. To me, though, refreshing and reassuring feelings overrule the irritating uncomfortable sensation: when I'm going to lighten my wallet on expensive gear, knowing it's going to last longer it's sort of consolatory.

Back in 2007, talking with a pro, I told him I was waiting for the release 5Dmark2 before upgrading to FF and that one would have been my camera for ten years: never really believed in what I had said then, but time has passed and, since I have skipped the mk3 and my next purchase will most likely be the 7D2, my prediction is probably going to come true.

...
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

LOL!

And Canon some NSA officer to make us happily tittle-tattle about geeky cool stuff...

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".....

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.
