Actually DOF of the same lens on smaller format is narrower than on larger format. You can check DOF calculator for that.
This has been discussed to death before, but in short, you can't compare DOF with same lens on different formats as they produce different images. If you're shooting a Pentax Q with a 21mm FF lens, and you switch to a FF DSLR using the same lens you go from a tight portrait FOV to an ultrawide, and the subjects you shoot would likely be different. If you did try and shoot people then you'd probably get a lot closer with the lens on FF, Q: what happens to your DOF calculator when you reduce focus distance for FF?
A: Reported DOF is shallower.
The facts are: if you maintain the same angle of view, shutter speed and total light captured (same entrance pupil diameter) then you get the same DOF regardless of format. If you maintain the same angle of view, shutter speed and exposure (same f/stop) then the larger format will have shallower DOF.
Finally, any format comparisons are useless until you take lens availability into account. Micro 43rds can produce the same shallow DOF as full frame (with the same framing) when using f/0.7 lenses (which don't exist), likewise medium format produces shallower DOF than 35mm when using f/1.4 lenses (which also don't exist).
This makes 35mm the optimum format for shallow DOF at common focal lengths due to the availability of f/1.4 lenses from 24mm to 85mm, hence the interested in a 35mm format NEX.

Not that extreme, but yes, I think another DoF discussion helps exactly none of us.
What actually bothers me is how much people quoting "DoF-calculators" while misunderstanding the basic concept are:
Actually, in reality, right now, in both a practical and a theoretical sense, willfully and intentionally - hurting the growth and misleading the understanding of photographic basics of people that make the mistake of actually reading them (and mistaking their statements for something actually connected to reality).
It's KIND of lurking the net, inserting comments like "camera ISO controls the light, making the light more noisy if you use a higher number". Not that that happens very often, but it's actually just as meaningful and correct as quoting DoF-calculators. That is: not meaningful at all and totally, completely, fundamentally wrong.

Knowing that uniform, clean, white light in reality is a noisy storm of random photons is one of things nobody tells us until we dig deeper into the matter. I think especially camera review sites have created the notion that image noise is something that the sensor is responsible for. The knowledge has become better over the years, thanks to many warriors on forums like here.
Try saying in a discussion about lens veiling flare and dynamic range that lens flare increases the shadow noise....

Regardless of technical explanations and theory stuff, the advent of a (fairly small and light) FF interchangeable Sony camera with
a) a very good high rez sensor (high twenties or 32-ish MP) with beautiful colour and large DR
b) a series of good, compact and light weight FF Zeiss lenses with sharpness up to the resolution and the "Zeiss look", all affordable: For a start, the classic trio tele, normal, wide (85/50/35) would perfectly do it for me...
c) a few innovative Sony tech, like Sensor stab inside, and maybe even sensor shift AF with movements in the "Z axis" (the new magic word?)
all this might make me reach for my wallte for the first time since quite a while. Another NIkon or Canon DSLR with "a little bit more for the same money" wouldn't.
Not sure how much of those "SR5 wonders" will actually materialize in a forseeable future, but at least I am thrilled. And yes, me too I think: Seems rather good to be true....
1) SR5: Three E-Mount FF cameras are planed to be launched within the next five months! And let’s hope Sony doesn’t change this plan
2) SR5: Two are NEX-FF cameras and one is a DSLR shaped (ILCE) E-mount Full Frame camera.
3) SR5: The first camera(s) will be announced soon and be in Stock before Christmas (Sources didnt’ tell me if it’s one camera only or two that will be announced now).
4) SR5: There is a cheaper and a more expensive NEX-FF to come (Sources didn’t tell if both will come at the same time or not).
5) SR5: There will be (a minimum) of two primes lenses (Zeiss 35mm f/2.8 and Zeiss 55mm f/1.8) and two High Quality zooms along the first camera announcement. These lenses are FE (“F”ull frame “E”-mount) lenses. (Editor’s note: One source told me about a portrait lens too but I have to triple check this. Could be the leaked 85mm f/1.8)....Show more →

No CZ zoom would be a mistake, they want to offer something akin to the very good spec 16-70mm for APS-C NEX I beiieve, not all buyers will be prime only people. A 28-85mm f4 or so would do the job nicely. We'll see. Sony do not have a good rep for NEX lenses.
Ed, you can expect the 55mm (and hope the 85mm also) to be similarly small after seeing the tiny 35mm. The ZM 35/2.8 is considered a great lens, speed notwithstanding. SIze/weight is #1 priority - the RX1 concept in ILC.
Hopefully a cheaper model with 24Mp, a higher end one with more Mp and a 'test bed' with the adapt all lenses mechanism - maybe the latter in a DSLR body to make it more palatable to C/N users looking to a smaller extra body - the first step in an eventual migration.
How would a 400 gram body with 36Mp appeal? Add some high end primes to that, fit it with IBIS..the timing is very promising, even if it slips a couple of months. It's fun to try to guess what they will do. Will it look more like NEX or RX?

Hopefully the camera will operate more like the RX-1 or a more traditional camera and come with a standard hot shoe. I am not a big fan of the wheels on the NEX7. That is why I went with the Fujifilm X-E1. But, we will have to wait and see. As I have mentioned previously, I truly expect that Sony will have something to show at least for the first NEX/E mount FF camera at Photoplus at the Javits Center which runs from October 24-26.

Apparently one new FF will be DSLR-like in form, and the other two will be NEX in form, so I doubt we'll see traditional controls, but no big deal. I've used Leica, NEX, Fuji and now the RX1 over the last few years, and it's very easy to move between them, control-wise. In fact, I found the Nex-7's dial setup to be very good and fast.

Yes, are we saying the 85/1.8 ZA is now most likely FF? That is good, and I thought that would make sense given it's a tele. If they continue down a 1.8 high quality Zeiss prime route then that sounds like a wonderful balance to me.
But they would need a 35/1.8, of course.
As for handling, as long as it's well thought out I have no problem with traditional vs contemporary. One thing I hate is big assed screens that hardly get used dominating the ergonomics though, which I assume Sony will continue with.
I hope it has an electronic shutter. We don't want any noise.

Definitely should have some sort of remote (preferably electronic) release and not by wireless only.
