The real innovation is in the price...

Looks like Sony is only what 45 years behind?
Actually Im thinking this was present in the older Minolta bodies, just making it sound new.

IMO you guys miss the point on picking just the pellicle mirror (which never have achieved any commercial success anyway). What's new is they marry this with an EVF which now offer features not possible before, and the EVF compensate for the related light lost:

1. One never actually see what was captured with an OVF (i.e. the mirror black out the image when its being captured)
2. All current dSLR AF focus are predictive (i.e. the camera has to predict where to actually focus when the mirror is up)
3. Check this AF video of a Canon 550 and A55 in action:
http://www.focus-numerique.com/sony-...news-2091.html
4. The bonus with an EVF is What-You-See-Is-What-You-Get (On an A2 for example one can adjust the aperture and shutter and see real-time result on the EVF of what's going to be stored to the flash card, i.e. highlight & shadow area clippings or a real-time histogram) - Oh and every single lens mounted on this camera will have IS!

-> Also remember the price point for what it does... i.e. what camera currently on the market does all this for this $$$ (i.e. less than a low-end Canon with 10fps, three central f/2.8 AF sensors, and GPS built-in)?

Great stuff from Sony.

Unfortunately it seems it's not possible to keep the IS in body and do good video too. I really wanted a NEX, but they've had to move the IS into the lenses for that format.

Which leaves those of us wanting a small EVIL camera with IBIS and a couple of pancake primes left out again. :-(

The downsides are:
  1. the Pellicle Mirror siphons off 2/3 stop of light, so you need to use a slower shutter speed and/or a higher ISO to make up for it
  2. the video only AFs at the lens' maximum aperture
  3. the EVF sucks up power like it's going out of style
  4. the A33/A55 use the smaller batteries that the NEX bodies use, instead of the larger, more powerful batteries that the AXXX bodies use
  5. you need 2 fully charged batteries to fill a 4GB card with large Fine JPEG images
  6. there are no vertical grip/battery packs for it
  7. at the maximum 7 fps continuous shooting speed, a single battery won't last for 40 seconds of shooting time
There's some innovation in there somewhere, I'm sure. I just don't know who might want to spend their money on it.

If you look at image resource you can actually see the effects of the iso between the a33 and a560, some sensor. But at higher iso, you can see the difference. That 1/3 lost of light to the sensor is something to consider when shooting in really low light.

But the really usable fps is 3, as the evf does not refresh fast enough if you are trying to use it to track a moving subject.

But it is a way better HD tool then the current dslr's with their liveview system.
