A Canon DSLR First Coming to EOS 5D Mark IV [CR2]

[Donkey_Kong]

I have a question regarding the proposed automatic AFMA:

Would the calibration occur instantaneously as each photo is being taken, or would it only happen once (say, the first time each lens was attached to the camera body? If it were the later, then presumably you would be able to tell the camera to recalibrate every so often.

I'm trying to discern whether or not auto AFMA would improve focus consistency, as well as accuracy?

Thanks in advance. Hopefully I haven't over-complicated a simple question.

Dunno what they're so excited to share, but I can say with confidence that DSLRs will continue to be a joke for serious video production (real commercial work, not film school BS). The 5d4 will shoot 4K at 30p, just like my phone does. Wow. And of course it will do so to a sloppy 4:2:0 8bit Long GOP p.o.s. h264 codec. There will be no option for XLR inputs. There will most certainly be no ND filters. I also expect no peaking and no zebra controls.

If Canon made a video-centric 5D Mark IV-s with internal 422 10-bit intra with 120fps+, and coupled that with proprietary EVF, XLR and ND modules (a la Red), the video production market would rejoice. They could build such a camera. Even at $5,000, it would sell like hot cakes. I'd dump my Sony Fs7 in a heartbeat. I'd invest more in Canon glass. But alas, Canon is stupid in their marketing and product development, so screw it. Life would be so much easier if I didn't love the Canon glass and color science.

Ohmygod. The weirdest message ever.

I'm mad at Toyota since my Corolla Mk3 doesn't have 8L-V12 twin-cam with double clutch. Such disrespect for customer, and they'll lose marketshare for that for sure. Unless Mk4 has those and BJ machine too, I'm staying with my Lamborghini. Unless they give me those Toyota will lose market share for sure, and it's beginning of doom for the company.

Charge the battery by micro USB connector on the body.

 

[Bennymiata]

I have a charger that charges 2 LPE6 batteries (and unchipped clones) that just uses USB.

It's really handy for charging on the go, and it only cost $10 or $15.

Although obviously everything is just speculation, it almost definitely is something you will have to start manually. You will likely need a properly illuminated (ideally flat) scene with good contrast with the camera on a tripod.
Even if Canon made this work with any scene, it would take too much time to do before every shot.

Thank you very much for clarifying.

I've wondered why Canon hasn't made an attempt at resuscitating ECF for their DSLR lines. That was also my first guess when looking at the heading.

On the topic of EVF/OVF combination: would it be possible to increase the resolution of the metering sensor to say 2Mpx (the 1DX mk II already has 360k pixels) and then overlay that image either using an OLED array between the prism and focusing screen or by shining on one of the sides of the prism? Even if the alignment isn't perfect, it could be used for focusing help, zebras, DOF overlay, AF point indicators, virtual horizons and such..

I would like to see

Removable wireless LCD (for shooting in really awkward positions)
ISO Priority
Auto DoF (pick two points, camera works out best Aperture)

None of these are particularly important of course, just what I would like.

ISO Priority: It's called Program mode

Personally, I would like to see a square sensor.

So you'd prefer a 1.18x crop sensor to a FF sensor? Or perhaps a much more expensive camera? Those, among other reasons (incompatibility with a few lenses and many lens hoods, etc.) means that idea is pretty much a non-starter.

Probably not a non-starter, but wouldn't be a reasonable feature to develop at this time due to sensor manufacturing costs. I've said before I'd love a square sensor that encompasses the entire (usable) image circle so you can choose your aspect ratio in post. It would be expensive. It would be a premium or niche model. Unlike some other folk here I don't think the world always shares my feature priorities. Whether I could afford it is something I won't have to think about for a long time.

The diagonals on 36x24mm sensors already use the full 43.3mm diameter of the FF image circle. To make a square sensor that would work with the same 43.3mm image circle you would have to shorten the width to increase the height. It would be a 30.6x30.6mm sensor with a 43.3mm diagonal. You would only gain roughly 8% in terms of area, from 836mm² to 936.4mm². But increasing the height of the mirror by 6.6mm to 30.6mm likely means the current 44mm registration distance would be too short to accommodate a mirror that size. So now you're talking entirely new lens systems with a longer registration distance, a semi-translucent stationary mirror, or the end of the TTL optical viewfinder.

+1000 That would be more than handy! Timelapses and video shooters would benefit alot (by using external usb battery packs).

 

[Michael Clark]

it has to be IBIS or auto AFMA.

Nothing else benefits "all" photographers.

Speed benefits all photographers. So some type faster interfaces were some of my first guesses.

USB3? That would fit as Nikon has already put USB3 in their cameras.

So has Canon. The 7D Mark II and 5DS/r have USB3 connections. The 1DX Mark II has a gigabit ethernet port!

 

[tron]

I honestly do not know - but does any Canon DSLR have GPS built in?

At least the Canon 1DX Mark II has buildin GPS. I want an EVF mirrored into the OVF if needed. This would be the best of both worlds!

And 6D and 7D2...

It would be a 30.6x30.6mm sensor with a 43.3mm diagonal.

No, it would be a 43mmx43mm sensor, covering the entire image circle. It would either be mirrorless or use a different mirror mechanism (sliding like a shutter rather than flipping?)

This has been covered so many times here, just look at the basic geometry of a circle and a square for goodness sake!

I'm sorry, what was the point?

Well, sure – at only twice the size of FF sensor, 1/3 larger than most medium format sensors and almost the size of the Phase One XF IQ3, that oughta be real affordable and fit just perfectly into Canon's lineup. :

Perhaps you missed this previous post. My point was merely that it's not impossible, just very unlikely at this time.

Edit/addendum: part of the point of the original post is that most of us have pet features we'd love to see, but our pet features don't necessarily make a compelling market strategy.

I did miss that. But in that case, you could just get the Phase One XF IQ3 now. With a vertical 3:2 crop from a landscape-oriented shot with that 100 MP sensor, you'd have about the same 50 MP as a portrait-oriented 5DsR shot, and lower noise, too!

Backlit keys like latest Nikon camera world be nice.. Also auto AF calibration at different distances and apertures to prevent focus shift.. But backlit keys are really nice..

Just say no to lit keys. I don't get you guys....
