• UPDATE



    The forum will be moving to a new domain in the near future (canonrumorsforum.com). I have turned off "read-only", but I will only leave the two forum nodes you see active for the time being.

    I don't know at this time how quickly the change will happen, but that will move at a good pace I am sure.

EOS 5D Mark IV & IVc Specs Surface, Most Likely Bogus [CR0]

How about the 35/2 IS ? "But it's just the old one with the addition of IS" !

Yep, I love those 24/28/35 IS refresh lenses -- anyone calling those 'the same old lenses with IS' has clearly never used either the new or the old versions and is simply rendering judgment off of the max aperture of both generations of lenses.

I want one of those IS refresh lenses in a 50mm so so so bad.

I think Canon must be brewing something really special up on that ;)

And when they do I insist you post a selfie opening the box ;D

A selfie will not be possible when that happens. Here's what will happen.

I'm convinced that Canon only cares about its competition with Nikon when it comes to its DSLRs. The 5D4 will have 4K if Canon believes Nikon will add 4K. Otherwise they have their Cinema series of cameras for you to pick from.

I don't mean to be a Canon populist here -- there are boatloads of opportunities for their gear to improve. But Canon has a sterling track record of small, pleasant surprises and gear that doesn't drop the ball. I'll take that over a scorching hot spec sheet that never truly delivers any day.

You missed what I consider to be the best reason to buy Canon..... it works with no surprises.....

Nonsense. Red. Above. :P

Obviously, I am capable of reading something while not seeing what I am reading :) I stand corrected!

Well, someone somewhere in a thread or was it this one, mentioned an increase of 1 stop in high ISO IQ. Well, the experts here would doubt the likeliness of such a huge step in RAW.

My wishful thinking about a next 5D body is: Should Canon come anywhere close to this one stop in high ISO improvement I'm gonna be fine with that. Hope they don't add to many MP. 22-24 plus some real enhancement in sensor tech would do for me. But other wise men here say, this would take a whole new sensor production line. Still, I'd wish to see some 6400ish ISO 12800,...

Time will tell...

The Sony hype train was derailed by the a7R II. Too many features in too small of a body and you end up with something that you would never trust for paid work. And that's just the immediate issues. I'm curious to see how many of those a7 bodies will still be functioning in five years.

Canon knows those people will come back around for the 5D4 and 1DX2.

That said, I expect to see 4K and higher DR in the 5D4 and 1DX2. No 4k in 2015 is okay, but this camera is for 2016 to 2020.

The 5D3 sensor has a quantum efficiency of 51%.... The 7D2 is at 59%..... a good guess for the 5D4 would be 62 or 63%.... call that a quarter stop more light.....

Looking at read noise, we have:
5D - 4.2
5D2 - 3.0
5D3 - 2.4
6D - 1.6
It is a good bet that the 5D4 will have read noise somewhere around 1.3 or 1.4....... almost a stop less noise.

I think it is quite possible that the 5D4 (assuming the same or similar pixel count as the 5D3) will have an additional stop of ISO performance....

With that thinking, we'd already have a 24-70 f/2.8L IS, a crop mode on our FF cameras, and pop-up flashes in the 6D. :P

We don't clone that much of what they do.

The 5d Mk. 4 is going to have 4k video. How anyone thinks otherwise is insane to me, every single camera at this price range and far lower that's released within the last 1-2 years has 4k. Canon is not going to sabotage their own flagship product just to get marginally more sales on the 1DX-2, anyone who can afford that camera in the first place would get it regardless of what the 5d Mk. 4 specs are.

Yep.

And don't larger sensors have more pixel binning work to do? I seem to recall A7 rigs shooting 4K getting crazy hot during use. Perhaps it's easier to deliver 4K in smaller sensors (like the Panasonic GH4) as there's less pixel-level lifting to do?

(Someone please straighten me out on this -- I'm very poorly read on these matters.)

My suspicion is that heat is the only reason why we don't have 4K video yet from a Canon.....

Look at the 7D2..... certainly the processing power to do it, but at what cost? I think that Canon will need a dedicated video codec chip to give decent 4K video at a reasonable frame rate without melting down the camera or burning through battery life....

On one of Max Yurev's youtube videos (https://www.youtube.com/watch?v=e_jzBpXu6WQ) he suggested that it may be the sensor-based IS that contributes to the overheating issue on the high-pixel-density A7R-II. He said that it's possible that they can't have an effective heat sink with the moving sensor. Seems a plausible explanation. The 4K over heating problems don't seem to be there on the the A7S-II (low pixel density) or the Samsung NX1 which Yurev has been shooting with for quite some time year.

I think the processor is not the bottleneck it is the IO bus. They need to implement a bus that supports USB 3 and SATA/PCIe. Until then none of their cameras can have 4k. It will take this to support CFast and UHSII SD. I think that Canon would be foolish to announce a camera that lacks USB3, UHSII SD/CFast or equivalent support. But SD cards are getting fast enough that there may be no reason for CFast at this time.

OK I'll take a fun stab at this guessing game.

Canon needs to make a much bigger leap this time around with the Mark IV, like from the 5D Classic to the MKII. That was a 60% increase in res, as well as a significant increase in performance. I also don't buy the argument regarding no 4K. There was no concern regarding robbing sales from their higher end cameras when they introduced the MKII with 1080P. The reality is 4K is now the new 1080P. I don't think they have a choice. 4k Blu-ray is now in stores, TV prices are way down, content is getting up there. More and more clients are going to be demanding it. A 5DMKIV with just 1080P will be an absolute snore...

Frame rate could remain the same without any problem, however that might be difficult with a big jump in resolution. 39.3MP would be a good start to say that they are really trying to compete with the D800, and it would work well with 4K. Although I guess that was what the 5DS/R was intended for, so I'm probably wrong on the resolution. Pricing will also be a challenge since the 5DS is at $3700USD, and should drop with time. Canon increased prices significantly on the last subsequent model jump to MKIII. Probably not in a position to do that this time.

I'm not sure why I'm not excited about the 5DS/R. It really seemed like a quickly thrown together desperation move. I don't feel the urge to run out buy one.

What are you going to offer up Canon in order to convince me to drop my 5DMKIII for that kind of money in the current field of competition?

Rumor mill has been pretty slow on the DSLR front lately. I don't really care about specs so much, however I am very interested in a release date. My 5D III is LOOOONG in the tooth, and all the extensive hours I've used it for astrophotography, it's taken quite a few cosmic ray hits and has often operated at pretty high temperatures. That's increased hot pixel counts and it seems to be a bit noisier on average than before. Really need to get a replacement for it soon, and since I'm tethered to an EF 600mm f/4 L II, I really need a quality Canon camera with good frame rate and high resolution to replace it with.

Hi Jon!

A little bit OT but did you let Canon do a recalibration of the sensor?
I don't know if that works for you and your astro shooting.
But I've recognized after some time of "normal" shooting an increase of red/hot pixels.
After sending it in and recalibration they were gone. So that worked for me.
Of course my exposure times get only up to several seconds but not as long as yours.
And of course a new camera is always better ;)
