Could someone give me a precise description of the differences between a65 & a77?
I checked in imagingresource.com, but there seems to be more than what they describe in the text.
I am glad to have chosen alpha mount over canikon. It seems that I am about to get a nice FF body (a850) at bargain prices from you guys who will jump to SLT .

Thank you in advance.

The A77 has an APS-C sensor vs the fullframe sensor in the A850. If you switch, do you have the equivalent lenses to move to the smaller snesor and shot the same subjects as you do today?

If you look closely, it has the a33/55 product description, hehehe. Likely it's the placeholder for the real thing :-)

It was tested in a German preview video and they reported that there is no delay. See this video at 08:22 ff.

I hope so, but I am not sure because that window that contained the IR sensor for remote control at the A700 now contains the grip sensor. Certainly it is possible that it contains both.

Finally got round to reading the dpReview preview article and the associated comments on the last page... My goodness there are a lot of pixel peepers on there!
C&C always appreciated

Especially considering it's still pre-production. No image quality analysis can be fair until the final product is released.

So far the A77 looks like an amazing camera at that price. My only complaints would be:

-Lack of SSS switch. How will I remember it it's on or off now, and I hate menu diving to change settings.

-SD instead of CF cards. I like the bigger cards, especially when wearing gloves (I shoot in the cold a lot) plus I already own plenty of CF and no SD

And my biggest problem: No meter mode switch. This one really bugs me, I flip back and forth between spot and center-weighted all the time with my A700. Hopefully it is possible to map a custom button to that.

All in all though, like I said seems like an fantastic tool for the price, I will definitely consider it, especially for sports and wildlife, I mean 12 fps with AF

Looks good, thanks. I hope the A65 behaves the same.

The only serious beef I'm seeing on the spec is the anemic buffer. The A77 and A65 with a 13 shot RAW/17 Shot JPEG Fine buffer have a distinct disadvantage compared to the A55 (20 RAW, 35 JPEG Fine) or A700 (18 RAW, unlimited JPEG Fine). I'm not sure what Sony was thinking here, as you'll max out the buffer in slightly over 2s in the best configuration at 8fps (that would be JPEG fine) where the A55 gets 5 seconds at its most similar config (7fps, JPEG fine) and the A700 will shoot until the card fills in its closest config (5fps, JPEG fine). Essentially the best configuration for the A77 (8fps, JPEG Fine) matches the worst config for the A55 (10fps, RAW) in burst length.

The controls issues generally look minor to me. I'd like Metering and SSS switches, but can live without them. Everything else looks good. But what I'm seeing in terms of fps performance is a thoroughbred which has been hobbled by one simple error. This is not an action shooters camera. If you intend to shoot a lot of action, the A580, A55, A700 and A900 will all be superior due to the far deeper buffers, as all but the A900 offer at least 50% more buffer in RAW and all offer at least twice the buffer depth in JPEG Fine, with the A900's 105 shot buffer and the A700's Unlimited buffer being head & shoulders above the A77/A65.

Frankly, the A77 should have had a buffer which matches the A55.

Moreover, it seems that you can have 1 card only! Either MS or SD, but not both at the same time. That is a shame!

I made a similar comment a few pages back, and feel that it's a little worse as I would always want to stick to RAW and it's not just the number of images that can be captured but the time to do so too.

So considering the 1sec max RAW burst in more real terms: if someone jumps you'll have to choose between capturing the takeoff or the landing, you won't be able to capture both!

And I saw the Sony promotional video on amazon which does have a burst in the middle which seems to be over in a flash - and I think that might have been an example of the maximum burst length available in RAW mode!
(and bear in mind with the fastest SD card I know of having a sustained speed of 25Mb/sec, the continuous frame rate once the buffer is full will drop to around 0.7fps)

So I agree; a headline feature of 12fps which is probably impossible to match with a traditional DSLR; but then severely hobbled by both buffer and SD, making it a far less attractive selling point.
