that 1/250 in auto iso makes the mode on the 5D3 useless for my needs, oh well at least an improvement on that...

I'm waiting to see if Canon will do anything at all to improve the af points issue , I may still have to get that sucker anyway.

Thank you!

Where is skibum5 to analyze this?

Stan, can the 1dx in Manual mode and auto ISO set exposure compensation ?


No

and is the highest Shutter speed in AVin auto ISO mode still only 1/250 sec?

No. It seems to be moving for me, anyway. This is not a mode I ever thought of using, but it's definitely not fixed at 250 or anything else. I've just shot it between 1/30s and 1/1600s at f2.8 at Auto ISO.


I think he's referring to the maximum shutter speed that can be set as the minimum speed that the camera can select in Auto ISO when in Av or P modes. According to the manuals the maximum settable minimum speed is 1/250 for both cameras. This doesn't really matter so much for the 1D since you can independently set the shutter speed range irrespective of ISO or mode. (I don't have either camera but the manual PDFs are part of my camera porn collection. )

I agree with everything Stan says about the 5D3 being the near equal of the 1-series for all intents and purposes now, sans the frame rate and tank-like build (though the 5D3 is very nicely put together). One of the things people tend to discount in the discussion of the perceived value of the 5D3 is the jump Canon has made to bring this camera up to a much more professional level. It definitely challenges your preconceptions.

I will admit that I haven't dug too deep for this setting because it doesn't have much value for my shooting style, but I have seen both 1/30s as well as 1/1600s shutter speed in Auto ISO mode in Av mode. If it were limited to 1/250, then I should not have seen one of the above, no?

Yep thats correct, I have seen in AV mode auto ISO max 1/320 sec thats as I hight it would go on the 5D MIII, just for a split sec then it drops back to 1/250 and stays there....

One last question stanj, have you noticed if the body of the 1Dx is thicker that the 1D IV's? I wonder if it will fit in my sound blimp. I have to use the 5d markIII without the BG-11 to fit it in that sound blimp, this dang battery grip is soo bulky and thick the 1D IV fits in there good tho.

Sorry, that's not something I can really answer as I don't have them both side by side. There's no _noticeable_ difference, but given that the RRS plates don't fit, I bet there is a difference.

It's also possible to toggle instantly between One Shot and AI Servo via a programmable button (I use DOF).


Can the 1DIII be programed between One shot and Servo via the DOF button?

Canon CPS said "No" so I decided to ask the experts Thanks


You can do it with the AF stop button on your longer lenses. Like your 200/2 lens

When the 1DX came out at only 18MP and no crop and no f8 focus, a lot of people, esp. birders, called foul and swore never to upgrade. Newsflash: the only two camps that won't upgrade are those who can't afford it, and those who are stubborn. Personally I would upgrade from a 1D4 to a 5D3 in a heartbeat; to the 1DX is a complete no-brainer. Yes, there's the pixel count, and it's a bitch. Trust me. As I said I'd prefer a very slow 40MP machine myself, it wouldn't even have to be tough as nails. But the 1DX _owns_ the 1D4. All your base are belong to us.

Now, is 2x the price worth it over the 5D3 for the majority of the people? There's something to be said about having two perfectly identical bodies. Then there's something to be said about having a camera that gives you the last squeeze of advantage that you can get. Is that worth $3500 to you? It greatly depends on your bank account, honestly. I stick with my earlier statement that very, very few people _need_ it, putting only the frame rate into the "true need" category.

Now as for high ISO - whether it's 1/3 or 2/3 or 5/3 stops, quite honestly I don't care.


Like Stan, I do not care whether it is "said" to be 1/3 or whatever. I ask: "Is it better?" If it is, that means a plus.

The frame rate? In many cases, 6 fps is sufficient, but twice that is a plus. I would not say that it is decisive for everyone, but a plus it is. But for me, subjectively, it is far from the most important reason why I would pick the 1D X over the 5D III.

Of course the 1D X is superior to the 1D IV, given the considerably higher price it would be near impossible to sell unless that was the case.

However, I have to say that the price is the only possible reason why I might hesitate for a moment before I save up for a 1D X over the 5D III.

- The 1D X has greater battery capacity, which is invaluable when in the wilderness with no possibility of charging. No, it is not an argument that you can always carry a spare battery - that holds true for the 1D X too, and then you have still greater capacity.

- The 1D X has an environmental sealing that is much better than what is found on the 5D III. Some might disagree, but the 5D is not properly sealed. If the wilderness is your arena, or if you are a sports photographer who just have to take the picture whatever the circumstances, this advantage is invaluable too.

- The 1D X is constructed to withstand 400 000 exposures as compared to 150 000 for the 5D III. This really makes a difference, which translates into a sound economic decision in favor of the 1D X. Yes, you could buy two 5D III for the price of one 1D X, but that does not change anything since the 1D X is a better camera to work with.

- Built-in vertical grip and ultimately better image quality is the icing of the cake, and a matter of course for a superior camera.

For the wedding, concert, studio and portrait photographer, the 5D III is a brilliant tool that should meet the needs.

For those who regularly venture into the wilderness and all sorts of weather conditions, bird or sport photographers with high numbers of shutter clicks throughout the year, I would say that the 1D X is neither overkill nor something that "very very few" are in need of.

The price is unpleasant, but the superior build, battery capacity and sealing as well as handling is what you get in return. I have helt prototypes of both camera in my hand, and I am not in doubt that many would be better served by the better camera.
