I'm going to be comparing the output to my 5D2 over the next 7 days and was wondering if the 1D4 is at F2.8 should the 5D2 be at F4?

I've done some preliminaries with my dog and the 1D4 blows the 5D2 away with autofocus but the overal static IQ and colours are the same.

That said I want the DOF to be equal to measure sharpness in all areas such as high ISO and Servo mode.

If there a way to correctly calculate the difference?

You will have the same dof on both cameras.

The problem comes when you want to compare photos side by side, you will need the exact same framing. This is where you have to take a few steps back with the 1D4. This results in a larger dof.

Use a DOF calculator to calculate the difference if you wanted to compare; here you will find the exact aperture difference to make up for the added dof due to taking a few steps back.

Have fun!

Thanks David,

So far the 1D4 is ever so slightly sharper which I put down to more consistant and accurate autofocus.

Now that I have my hands on it and as I used to have a 7D it makes the '7D vs 1D4' threads look a bit idiotic.

Love the extra focal points,
Colour, noise and overall IQ are the almost same when shooting Raw, the 5D2 having less noise at ISO3200 onwards.

The 1D4 is slightly lighter (my 5D2 is gripped) and the only thing that really matters to me is the better autofocus and AF points.

I would be losing full frame and 6mp in the swap so am considering a 1D3 to compliment the 2 5D2's I have instead.

One thing I have to add, the way the image comes across is like the 40D, odd I know but it's almost as if they took the 5D2's sensor, and cut the thing down in size and in doing so lost 6mp. The reason I mention the 40D is that out of all the SLR's I've used (40D, 50D, 7D, 350D, 5D, 5D2, 1D4) Only the 40D, 5D2 and 1D4 have the same sort of 'look' to them.

I wasn't terribly fond of how my 40D photos "looked", especially at iso800+. :lol:

Different strokes for different folks. I'm curious as to the 7D vs. 1D4 threads you had mentioned. I haven't really noticed any comparisons between the two. I was also under the impression that 1D4 should be cleaner than 5D2 at iso3200+

Sorry, I wasn't relating to noise on the 40D, just the similarities between how the overall image came out at low ISO like 100.

I never liked the images that came out of the 7D, just seemed a bit cold compared to the 5D2 and 40D but the 7D has a different WB system to the other two.

The 5D2 definitely has the edge at ISO3200 though, when viewing RAW files but then that could be down to the exposure being slightly out.

To take the exact same photo (same perspective, same framing, same DOF) a 1.3X sensor will need to use an aperture 2/3 stop faster than a FF sensor. You then also need to control the exposure by using 2/3 stop lower ISO.

As usual, it depends on what you use a camera for. I wouldn't take a 1D4 over a 5D2 if doing low light or even semi low light work - the AF apparently doesn't do as well in low light and the noise threshold is worse. If I were shooting sports, sure. But really other than the bajillion focus points I don't realize much difference between it and the 7D. The noise is about the same. 2 FPS doesn't break the deal when one is 8 FPS vs 10, its a 1.3X cropper and requires more light, etc etc etc.

Its a nice camera, but I don't think its to be compared to the 7D or 5D2. 5D2 is your "take your time and make something beautiful" camera and the 7D is a run and gun 1.6x cropper with excellent pixel density and noise threshold. The 1D4, to me, just adds more focus points (that I don't use, I use single points in servo) and a "better" AF which is almost hard to believe because the 7D is that good.

If you want only one body to handle everything then the 1DIV is the way to go. But a combo of a 7D and 5DII is a very similar cash $$ outlay and gives you great performance for "all" your shooting needs. I will be adding a 5DII next year and I have owned a 1DsII so have experience with the 1D class bodies. In my opinion very few shooters actually need the bullet proof & water resistant qualities of these pro bodies, I certainly didn't. If anything I baby my gear which I think mirrors most shooters. Not all but most.

Wow! You mean a camera built for sports that is twice the prices has better AF? Shocking.......LOL ;-)a

I've got both. Get use to the 1d-IV, I think you'll find it a bit better than the 5d-II at high ISOs and definitely at lower ISO's. Other than my wide lenses not being wide enough on the 1d, I could dump my 5d and not miss it. (plus the size, a lot of times I prefer the smaller bodies).

I've only shot briefly with a 7d. Nice body, more than adequate for me and most others, but....... :)

I've shot with a 1D4, wasn't $4500 worth of camera to me. High ISO performance was worse than a 5D2 and the focus was worse in low light than the 7D. Iunno.

Just finished a shoot with it and am waiting to start another. I'm not complaining but too many AF points holds things up lol.

Very sharp though but I'm finding it hard to fit the model in the frame (In a hotel room) so need the wider frame.

I did consider the 3DS but it's low light performance sucks and all it has better than the 5D2 is the autofocus system.

The 5D2 is hard to beat!
