I'm surprised Sony is still clinging to the word Translucent.

Translucent means it will pass light diffusely, which means a lot of scattering and poor for imaging. A flash diffuser is translucent. Lenses are transparent.

If Sony really means translucent, it is not good!

I guess the term would be semi-translucent. It seems to be similar to the mirror system that canon used on their Eos RT, which they have long abandoned.

Concerning the new Sony, it does appear that 24 Mp is too much of a good thing - the photos posted on DPReview do not bode well, especially at ISO 1600 - muddy and noisy.

I hope that Nikon does not follow this route for their new release.

i just saw a video showing the a77 - considering it does not have a mirrow to throw up and down the shutter seems very loud .

I guess the term would be semi-translucent.

So you would like all your images semi-fuzzy?

[Sinuhe Hahn]

Sorry - I meant semi-transparent

Wikipedia has a ref on the development and use of the Pellicle Mirror, which was 1st used way back in 1965......

Having seen a few more video's of the a77 the shutter might not be as loud as i first thought .

Im suprised there is not more coments on this - as a wild life / bird photographer the shutter noise of my mk3 and 7d really loses shots as it can scare the subject away after just 1 shot.

Well its news from sony,if it would have been from canon or nikon you should have got 100 answers in the the thread and it have been fantastic!
Its the same in sweden they try to keep the lid on as much as they can on sonys new innovations and keep silent.
But fact is that sony is the only one coming with new ideas at the moment.

Kenneth,

Perhaps it's because it is a wait and see how it really performs. And it is not a new innovation, as Canon had this, what, 20+ years ago.

I think the camera is interesting from a HD video perspective as it has predictive AF during HD filmng. But the EVF means a readout delay, so for fast action photography it seems like it has a significant weakness (EVF) when the no mirror movement idea should have moved the camera into a faster realms. And one has to wonder what the beamsplitter will do to image quality. This is not the film days and today's digital pixesl are very small requiring unprecedented image quality.
