How much better would the 5D mkIV have to be for you to upgrade from your mkiii?

[birtembuk]

5D3 is a great camera but I have the same remarks than some about DR, banding and low light focusing ability. I will watch closely the development of the "3D". If this hypothetical one leaves up to expectations and is in a 5D form factor, I'd upgrade and complement it with a 7D2 for high fps. Let's see what's coming up in the next 6/8 months.

The 5D line will always be worse than the 1D line. I will never downgrade.

Bigger buffer and/or a fast interface on both cards.

This will sound "out there" but what would really be hot would be a built in AFMA system that automatically calibrated each lens to each body (say like FoCal) with the touch of a button. That way, before you go on a shoot, you push a button, it autocalibrates exactly, no targets needed. I would also like to see some really great new sensor technology.

I do love my 5DIII

I would love that feature! Might not be all that impossible. Maybe one day we will look back and laugh at ourselves for manually calibrating our lenses!

I liked calibrating, but that would be a great upgrade. I also like the one suggestion of making it Google glass compatible. I really miss the articulating screen from my 60d.

AFMA is only needed due to slight tolerances between the relative position of the sensor and AF chip, and the alignment of the secondary mirror. If DSLR's used on-chip AF (which is possible even with a reflex mirror) there would be no requirement for AFMA.

We already have what appears to be a good on-chip PDAF system appearing in the 70D, so why couldn't the semi-translucent main mirror just let what AF light passes straight through it go direct to the main sensor instead of to a dedicated AF sensor down below via a secondary mirror?

AF Speed. The on chip AF does speed up live AF to merely slow from painfully slow. Its still not comparable to conventional PD AF and worthless for fast moving targets. .

Hopefully, they can do something about it to speed it up, but on FF with even more pixels, it takes a more powerful processor just to stay the same.

The X100S seems to do a reasonable job with its own PDAF sensor. If this 70D on chip PDAF really is slow even in photography mode (as far as I know its geared up for video by attempting to replicate smooth focus pulling), I can't see any reason why the second generation dual pixel AF sensor together with suitably powerful dedicated AF processing can't get this one cracked. The Samsung Galaxy S4 has a 1.9GHz quad core processor, so an upcoming top end mobile processor branded as DIGIC for AF could well do the trick.

TWO stops improvement on ISO? What does that mean? At the high end? If that happens, then Canon will also have made flying cars and microwaves that serve you your dinner straight from the kitchen into the living room, where you are watching your $150 93-inch LED TV. None of those items you listed make any sense at all.

Half a stop to 3/4 stop of IQ improvement at ISO 25.600 and 51.200 in RAW by 2015/16? Likely? I think, the main challenge here will be sensor fabrication tech, improved DIGICs and MPs. What I really would like to see is Canon staying at 22.3 MP in the 5Ds

Hasn't the 5D3 only just really reached the masses in a reliable supply?
First few firmware updates completed and all that?

Oh well, i suppose that sort of thing had to start at some point after the first member on here actually owned one.

For me, not likely to be upgrading to anything any time soon - due to austerity provisions being in place (unemployed!) Also, quite enjoying Street Photography with my Fuji X-Pro 1, people don't seem to get as 'offended' with that camera as they do with the 5D2 and 24-105!

just remembered, I'd have to upgrade my computer as well, as i'm well entrenched into Adobe LR, and my computer won't go newer than V.4.

Well, time to go, blue hour is rapidly approaching and school hols are here - the teeny bike park down the marina is just begging to have a camera pointed at it

 

[thelebaron]

for those clamoring for an integrated battery grip, why is a separate model not good enough?

 

[alew3]

Wouldn't make me upgrade. But the mkIII should have had USB3/Thunderbolt port for faster tethering / image downloads! Not sure why USB3 didn't make it.

The point is that the mkiii is really really good and there are few, if any, complaints that it seems to suggest that the mkiv has to borderline incredible to really see value in upgrading.

So what borderline incredible feature do you as a MKIII owner would cause you to spend $2500 on an upgrade. For many of us, the answer is that there are no upgrades that we can foresee that will push us into an upgrade.

 

[jdramirez]

I know... I don't see what the big deal is. Just buy the Canon grip if that is REALLY the only thing that is missing from the mkiii. I personally prefer the size of the body without the grip. It isn't like you CAN'T buy a grip...

USB 3 is rare to find on cameras because image downloads from current CF cards don't warrant anything more than USB 2.

Current CF cards top out at about 100 megabit/second. Thunderbolt 2 runs up 20 Gb/s. USB 3 runs up to 5 Gb/s. The antiquated USB 2 system runs at 10% of that speed, 480Mb/s - still about 5 times faster than current high end CF cards.

 

[pedro]

62% in the poll voting for a two stop ISO improvement...

Maybe an improvement of 2 two stops DIVIDED in 4 ISO marks is realistic: half a stop of IQ improvement at ISO 6400, ISO 12800, ISO 25600, ISO 51200 each? All this gives us a quite usable ISO 102.400 ;-) Concerning high ISO performance, any 1Dx upgrade (announced by Q3 2015?, could make 5DIV a Q2 2016 announcement) will slightly set the stage for what might be expected high ISO IQ wise.

Erh, no. The top-end CF cards (like the Lexar 1000x) tops out at just under 100MB/s, ie 800Mbit/s. Also, USB2 is horribly inefficient so 480Mbit/s is "guaranteed not to exceed numbers" not real-life numbers.
I haven't looked into the USB3 protocols, so I don't know if they reduced the overheads.

Give me most of these and I'll consider:

1: Two (or more) stop improvement on ISO
2: 720p240 (I'd be ok with 1080p240 too)
3: 10fps+ (and naturally plenty of buffer, ~20+ would be nice)
4: Dual-CF slots with separate data channels for writing (so it could flush buffer to both cards, roughly doubling the speed it can empty the buffer)
5: Integrated grip (=1D style body (I know Canon don't want this, they want 1D to look the king))

Dude, I'm curious-are you serious or is this american sarcasm/irony?

I'm a Finnish guy, not American. And yes, I'm serious.

Tell me one of those that shouldn't be in 5D4? I know the #5 is out of reach for political reasons, but all others should be fine.

?

I'd be happy to hear your reasoning why none of those make no sense, because for me they do.

As for ISO, let's say 5D4 ISO25k looks as clean as 5D3 ISO6400. That's bit stretch, I agree, but I thought the idea of this thread was to make a wish list. The other points are really nothing special, don't you think?

Let's check (I'd be really happy to hear your counter-arguments, instead of just saying "make no SENSE!!!" without any words to back up)

#2: 720p240 is not that much really, pure data-wise it's only double compared to 1080p60, which is standard in any camcorder nowadays. Doubling data-speed is nothing in electronics, happens roughly every 3 years. And I'd take 720p240 any day instead of 1080p60, if I could choose, but of course different people have different needs.

#3: 10fps+ This is trivial, 1DX already goes 12/14 fps, so nothing new here.

#4: Saving to two cards is nothing special either, but it needs own controllers for both channels to maximize the speed. Basically same idea than RAID-0 in PC world.

#5: Again trivial, but this one doesn't happen for Canon line-up reasons, they don't want 1D-style bodies for 5D-series.

Good point actually. I just can't imagine using body without grip, so I'd be happy to get the bigger one to start with. Especially as the grip wastes lot of space with the connection and such, they could add wifi/gps/bt/LAN-port and such easily if they saved that much space.

That's why I'd go for a half of a stop improvement at each ISO setting up from 6.4k to 51k in RAW. An improvement like this would make a difference even at 102k.
