Most significant item spotted - the OLED viewfinder can overheat and has an overheating warning in the various display listings.

We will see...

Yes, sorry, but I removed the files from my server and uploaded them to other place, because the big traffic.

Thanks Pako



That for the EVF is interesting.

Someone can explain the point of the electronic front curtain shutter and why there is ON/OFF option for it.

From the brochure: Approx. 0.05 sec. minimum release time lag

Accelerated shutter response lets you
capture decisive moments with confidence.
An innovative electronic front curtain
shutter in the image sensor slashes
shutter release time lag to a class-leading
0.05 second* (approx.) and produces less shutter noise and vibration than a
mechanical front curtain shutter. If desired,
a mechanical front curtain shutter
can be activated through the MENU.

Here I have some flash animation for this (the second) - http://alphaforum.net/forum/viewtopic.php?f=99&t=558

that is the translation:
Electronic front shutter curtain + Mechanical rear shutter curtain / Mechanical front shutter curtain +Mechanical rear shutter curtain
Front shutter curtain Rear shutter curtain

Electronic first curtain - The first generation SLT cameras had a significant shutter delay when using flash. This was attributed to the camera having to close the shutter, clear the sensor, open the the shutter, fire the preflash, and then take the normal exposure. I do not recall if the camera had to close the shutter between the preflash and taking the normal exposure, but I would expect so. Non-SLT cameras use a different exposure meter for both ambient and flash exposure metering. The SLT uses the main sensor for both.

The electronic first curtain is supposed to get rid of the pre-normal exposure shutter dancing and its consequent time delay. Based on the delay time stated, it seems to work. I don't know what the negative effects of electronic shutter are (I can only see advantages (shorter delay and less shutter actuations.) But there must be some negative if they offer an option to turn it off.

Someone can explain how A77 has Peaking MF when tthe camera don't have Contrast AF ?

[David Kilpatrick]

Because, like the A55, A550 and many earlier models it does have contrast MF... not AF but MF. Live View Manual Focus Check.
