DoF is entirely a product of the aperture diameter. So a 24mm F4 will have the same DoF as 48mm F8, 12mm F2 etc etc.

As someone explained to me in another thread, for equivalent photos this phenomenon cancels out larger formats' high ISO advantage for completely equivalent pictures. For example to maintain shutter speeds, that 24mm F4 on an FF camera will need to be shot at 2 ISO stops higher than 12mm F2 on an MFT camera. At which point the noise on the FF is at best the same but in some cases worse if we are talking very high ISOs.

So my question is, for folks who have used an array of different formats extensively, how much does this affect real world shooting? Did you ever find yourself frustrated with the inability to get deep DoF from larger formats, or is it not that big of a deal?

It seems to me more and more like no format is superior to another... they all have advantages and disadvantages that make them better for different kinds of photography, with no clear all around winner

There have been a few tests comparing this.

One I remember, current M4/3 sensor (E-PL5 IIRC) vs D800 at ISO1600/6400 - D800 was obviously noisier (At the full picture level, not at 100%, where it's obviously going to be noisier).

However, I would expect the D4 to be essentially identical to the E-PL5 under those circumstances.

I'm afraid I don't have time to find links right now.
