1DX vs 5D3

[Viggo]

Strange about the AF being so much closer together than I would have expected given the whole iTR and metering a stop lower and faster motorspin...

Dissapointing as I am trying to justify getting the X (currently owning the 5d3) I must say, I miss the 1-series... And AF and tracking being the main reason I would upgrade...

I read the KR comparison and find it interesting when he talks about how the ISO of the 5d3 is incorrectly calibrated, so when you set it to ISO 100, it really is shooting at 160-200, and so on. For marketing purposes it would help since now 12800 is very usable even if it is only 6400, and also explains why the 5d3 at similar (100-400) ISO's has more noise than the D800...

Dont agree with this!

The 1D series has better sealing but the MkIII and the 7D are not that backward either, Certainly not Dead!

I'd agree on the 5d2, although it did survive a Burning Man just fine with all that fine dust & grit (sent it in for cleaning afterwards though). My 5d3? Based on it's feel in my hand I'd say with an appropriately weather sealed lens it'd probably last through a rain storm. Being dunked in water? I highly doubt it, although I wouldn't be surprised if the 1DX could survive brief immersion in extremely shallow water. Assuming the lens cooperated of course.

You can buy a single-use camera for underwater use for 10 bucks, please don't tell me the best reason we can come up with to get a DOUBLE priced 1d X over a 5d3 is the damn weathersealing???

Please compare that underwater camera to what the 1DX can do. No real comparison.

Leaving that aside, 2 different target groups. The single-use underwater cameras are only good down to a few meters, no interchangeable lens system, no super advanced controls, no real viewfinder. Oh, and probably use ISO 400-800 film, which they develop and give you a CD.

And no, the price difference is not purely weathersealing. Some of the cost, yes, but much of the rest is different sensors, more electronics/processors, additional AF & metering, built-in dual battery grip, etc, etc. Oh, and the shutter can handle more actuations and double(!) the frames per second. And take more frames until the buffer is full. There's a ton of small and large things between the 1DX and the 5d3.

Please don't tell me the best reason we can come up with to get a FOURTEEN HUNDRED dollar higher priced 5DIII over a 5DII is better AF???  Please don't tell me the best reason we can come up with to get a DOUBLE priced 5DII over a 60D is a bigger sensor???  Follow that logic to the end and you'll be doing all your shooting with that $10 disposable camera.

The only thing the 5D3 does better than the 1DX is the silent shutter.

As far as IQ goes it is a leap ahead. I'm sick of seeing performance based around ISO.
Quality of the files themselves, their clarity and their dynamic range is also a big factor.

The 1DX renders files like no other. It's absolutely superb.

I'm a wedding photographer who's shot 12+ weddings with the 5D3 and 5 with the 1DX.

Well, that's taking it to a even farther extreme than I did ...

My point is, I know the spec lists, I know the 5d3. But from the OP and others I read around on using BOTH cameras it seems like half a stop better noise, which is pretty much expected at 4 mp less and "better built" is it...

But the 1d X is being said as to have WAY better tracking and AF accuracy and speed, but I'm just trying to see if that is Canon-talk, or if it really offers a much better AF and tracking than the 5d3, which in all honesty, could be better and it could be WAY worse like the 5d2.

Misunderstand me the right way. I think the 5d3 is the most substantial upgrade from one model to the next Canon has EVER done, and it couldn't be any better at that price point.

MY point is, what does the 1d X offer in real life, that defends paying double? I've dropped my 5d3, been out in soaking weather drowning where my 50 L started to fog up inside and still the 5d3 didn't miss a beat. So build is very good.

If the AF/Tracking, in real life, doesn't offer anything better than the 5d3, it's half a stop better, heavy as crap (compared) 200 images more on a battery(used to be 2000 images more) no headphonejack, no better DR(?) I just can't see the point....

So of anyone using both cameras can show me a clear cut difference and situations where the 1d X kills the 5d3 for tracking and or IQ in 6400 iso light, I so want to see it, because there are a lot of features with a 1d I would really like back (used to own the 1d3 and 1d4), but not at any cost. Not when I see just how much better camera the 5d3 is over the 1d4.

Why is the Porsche 911 Turbo S better than the 911 Carrera?  If you have to ask, maybe a Toyota Camra (pun intended) is the better choice for you?   

Here's what Bryan at TDP says:

Canon EOS 1D X Feature Advantages Over the EOS 5D Mark III  
More advanced metering system (100k pixel, 252 zone RGB vs 63 zone iFCL)
EOS iTR AF (Intelligent Tracking and Recognition AF including facial recognition)

Higher frame burst rating (RAW: 38 vs. 18 rated / 54 vs. 33 tested)
AF point-linked spot metering and Multi-spot metering
Faster AF driven by more powerful battery pack (with select Canon L lenses)

So you have seen that the 1DX is far better then the 5DIII when it comes to Image Quality?  If so that is certainly saying something as the 5DIII files are really nice.

that is backwards the 5D3 is more conservative than 5D2 for rating ISOs so when you shoot ISO3200 with both the 5D3 is really already doing what the 5D2 would call ISO4000

[LetTheRightLensIn]

Dual DIGIC 5+ processors plus DIGIC 4 processor dedicated to AE functions
(5D III has a single DIGIC 5+ processor and a non-specified AF-dedicated processor)

having dual digic itself is a disadvantage since it means no Magic Lantern

of course the things it allows, already mentioned, more fps are great

[JR]

What about the dynamic range?  Any thoughts on how the 1DX stackes against the 5D mkIII in that regards?

[heheapa]

I missed the HDR function in 5D Mark III. Hope will see the feature in coming 1dx firmware release
