The model code 'A79' implies it is a sucessor to the A77 APS-C camera. A full frame would be expected to be an A9*. But then it's only a rumour

If it is a full frame, and it is called a79, Sony has really messed up their model numbering.

If it is a APS-C camera, is those 32MP not to much for a APS-C sensor ??? again !!! the MP war is still going on ? or rather the Sony prestige war !!!!!

My concern are that the price will be much to high ? with that much MP what will the noise performance be ? will it have a decent Jpeg engine this time ? could focus peaking still work with this mirrorless design, and so on....

Why? The current 24 and 16 MP have the same noise when compared with correct methods (using the same exposure instead of the same ISO, and comparing the full photo at the same magnification).

The 24 MP sensor does seem to have some problems catching all light from really larger apertures, but that is the only difference I know of, and I don't think it will be relevant to many.

If you are complaining about file size, then it is really irrelevant whether the camera is APS-C or FF. A 32 MP file from FF will be just as annoying to handle as a 32 MP file from APS-C.

All these rumours sound really enticing but as someone on the alpharumors site has said, Sony seems to be no.1 in leaking information but dead last in releasing new products.

it may be a apsc..i imagine the new chip/sensor might handle  those 36mps.  a 4gb buffer? whaaaaat?

a magnesium body and 8-14 frames a second.

if its full or aspc one thing that is for sure..not going to be cheap my friends.

how are the lens resolution tests going to look with this body?- or is dxo going to 'well we used an a200 for this test.  to see a complete explanation on the other page on how these resolution test are not worth diddly half the time ha ha ha .  thanks for the link,brian

I was thinking the same. That is more than 90 raw+JPG photos if they use the same compression as a77.

More than 6 seconds of continuously shooting 32 MP raw+jpg with 14 fps...

(And 80 seconds to clear the buffer if they haven't increased the write speed to the card since the a77.)

Interesting. SAR stated in the comments section that it is indeed APS-C, consistent with the A7x numbering system.

If they really are aiming for early 2014 release then I'd expect a few more details by now; that's only 6-9 months away, not very long at all when producing a new device. I wouldn't be surprised if it was second half of 2014.

On sensor AF: well we knew it was coming and that SLT was merely a stopgap. I sure hope that they've done it well, but I suspect that the low light AF will probably be inferior to the standard system. People on this forum will probably go ape about it.

On the plus side, no SLT means an unimpeded sensor, no light loss any more, even if it was only a half-stop.

They can't make the system much smaller though, because the distance between the sensor and the lens flange has to remain the same.

32MP seems a little exaggerated for APS-C. Perhaps this pixel density allows the removal of the anti-aliasing filter.

Overall good to see sony innovating. Devil is in the detail though, and the AF performance, which is one of the USPs of DSLR, will have to be up to scratch, otherwise we may as well just buy nex's. Indeed, if they implement the same AF system on the nex cameras there seems to be little reason to use bulky cameras like the A79, apart from ergonomics and a large lens collection.

Taking most of that with a pinch of salt, but all good if true.

But I want better high ISO performance than that on a65/a77.

Just want focus to remain at least the same as current models.

But one thing I really want is touch screen, which I can use for quick focus selection. I miss this from the NX300.

And more customisation for buttons - yes, also letting me use them in RAW/Manual mode! Argh! Wanted to assign AEL button to focus point selection, but nope, this button has no function in manual mode! Similar prob with some buttons in RAW. Sigh.

If you don't want more MP then the answer is simple ,stick with the older cheaper cameras ! The received opinion that more MP is always bad cannot be decided on theory alone because each new generation of sensors tends to be better in several respects.

More MP unquestionably gives more cropping power & resolution but if you are a low light shooter then maybe those features may not be a high priority ?

If the rumoured specs are true then it looks good ! Better EVF & 480 focus points on new high resolution sensor.

The Achilles heel of current mirrorless cameras is relatively poor focussing compared with conventional DSLRs but this new senor may have cracked that problem in a similar manner to that of the Canon 70D ?

Just noticed that this rumour is categorised as SR3 so it may not be accurate but if so which part is untrue ?

It actually does.

If your AEL button is set to AEL toggle and you press it, you will see an asterisk symbol in the viewfinder. After that you can do exposure shift with the front or rear wheel. So if you lower the shutter speed with one stop, the aperture will automatically close with one stop and vice versa. Press the AEL button once again, and you are back to normal operation.

Once you have pressed the button, you can take several photos in this mode, making it pretty handy if you want to shoot with different combinations of aperture and shutter speed without changing the exposure.

Pentax have the same feature and they are so proud of it that they have given it a name so they can use it in marketing. On Sony it is just a hidden feature which most people will probably never discover.

Unfortunately it only works when changing settings with the wheels. If the aperture is stopped down because you zoom in, and your lens has variable max. aperture, the shutter speed will be unaffected.

Sony has not assigned a model number for thi camera. I think it has been named by the rumor sites which would make it unofficial, so it is hard to determine whether it will be full or half frame.

Is it possible this isn't a "net MP" figure?  The Canon 70D sensor is said to be 40 MP, so that's one of the possibilities.

I wouldn't be surprised to see it named the A7.

Three digits for DSLR - A700

Two digits for SLT - A77

One digit for mirrorless - A7 (NEX-7)

Is buffer made up of computer ram? Why don't cameras have bigger buffers? RAM is dirt cheap. I'd gladly pay a couple of hundred more for insane buffers.
