wow thanks for the news albnok...... so much poison, but yet have to resist.....

There are more high-resolution pictures here:

zstan: I don't remember any lag.

kevinwcw: Unfortunately, it seems a lot of people presume that translucent mirror technology means EVF. We'll see.

lwliam: Good point, but why would they go halfway there? Even the Sigma 15-30mm and 17-35mm have far more curvy front elements. The only lens I can find with a flatter profile is the Minolta 20-35mm F3.5-4.5.

I am really, really hoping to see a 'translucent' with OVF for the A77 or A7xx. Plus some kick ass new features for a semi-pro body. We know Sony has some kinda new AF system in the works - the A33/A55 has more AF points and can track moderate speed moving target quite well.

Here's hoping that they can enhance that and put the kick-ass updated version on the A77/A7xx

Couple that with a 10fps and a bright 100% OVF with HD video and Sony will have a winner in their hands.

if using OVF on translucent tech.. is it enough light to bounce the image?

8tvt: YES there would be enough light.

Now let's say the light loss from the translucent mirror is 30%. That is the brightness difference between F3.5 and F4.0.

You put your 18-55mm on, at 18mm, and you change to the 55-200mm at 55mm. Can you tell the difference?

8tvt : That's why I say I'm looking forward to it. With CURRENT knowledge, there's just too little light for a good OVF but who's to say Sony does not have some kind of revolutionary solution to this issue?

They already implemented a 100% OVF with FF sensor based stabilization that most people say was impossible then.

They came up with the Quick Autofocus Live View.

They came up with the Cobra Action F58.

I wouldn't put it past them to come up with some kinda surprise.

i agree, the drop in light to reach the OVF will be quite high.. with that portion of light going to sensor and OVF, what's left for the PDAF will even be lesser

what's the reason using EVF?
cost cheaper and maybe make camera lighter?

i notice some cons of it..
-drain more power
-difficult on MF
-some lagging issue

if A77 came with OVF and big battery with other additional features..
surely next move will be manual movie controlling..

lwliam, shootkk: As per my response to 8tvt, the 30% light loss is tiny.

8tvt: Manual focus with the EVF is a lot easier! It lets you zoom 14x on whatever you are focusing on!

Also, you cannot see the DOF of a F1.4 lens on a regular OVF with a Type G screen. You only see the DOF of a F3.2 lens. Then you shoot and you see eh why the DOF is shallower than what you saw in the OVF? Or why is the picture so underexposed or overexposed? Or why is the picture so orange or blue or magenta or green?

You don't know until you took the picture.

Unless you have an EVF.

lol. wikipedia might be a good start for all those technical terms. but for lens specs and review, i usually check http://www.dyxum.com/lenses/index.asp and http://kurtmunger.com/index.html

i don't know. lol.

oho.. seems like EVF can preview more accurate like final image..
now it making sense for budget and newbies photog..

but why lcd preview looks bad like not enough light - (forced me not to use it)?

8tvt: Have you tried the EVF? It is not the same as your A380! The MF Check LV on the A550, at 14x magnification, looks a lot clearer than the A380 with 2x Smart Teleconverter.

If you feel the EVF is dark, pull out the rear LCD screen.

Have you also tried putting the A33 on say your left eye, and the A380 on your right eye at the same time? You can see which one is a lot bigger.

It is a different thing, and a lot, lot clearer.

My Peleng 8mm F3.5 fisheye for example, cannot be focused by eye. I have to estimate the distance to the subject.

On the NEX-5 I can get 14x magnify and get exact, sharp focus.

The EVF with 14x magnification is also good for professional photographers, for example when shooting food, or macro, or using manual focus lenses, or shooting JPG with a custom WB.

ohh love this discussion.

to make OVF with translucent is NOT hard... all they have to do, add 1 more translucent mirror LOL!

so it goes like this, the ori mirro stay, reflect the rest of image upwards, then using another mirror, have 70% pass through into a prism/OVF, then the reflected from 2nd mirror goes to the AF module! w00t!!!!!!!!!!!

albnok: i not try the A33, i went to the shop all put inside the glass cabinet..
the only option just read² read..

will try it some other times @ SC..

I have nothing against an EVF but as of now they still have room to improve. I have tried the A33's EVF and it did not jive with me. I wear glasses and it seems that the EVF is only clear at the center when I peer into the viewfinder. The edges are all blurred. I do not like that. In future maybe they will be better.

Anyways, we are all jumping the gun here. Let's just wait and see what Sony has to offer first. It's gonna rock the digital imaging world I'm sure. Nikon and Canon has no SLT and if the A55 sells really well and the A77 is up to par for a semi-pro class, Nikon and Canon will be scrambling to offer something similar.

albnok & signither: thx for the source, now i know wat i can do after my exams.. haha.....

maybe because of the bokeh..
coz EVF can preview most accurate?

From what I understand here, is it something like the image below??

yup yup

No. Definitely not bokeh. The edges become sharp when I look directly at the corners of the viewfinder. It's when I am looking at a subject in the center the edges blur out for me. I'm sure it's something to do with my glasses and the way I'm looking into the viewfinder but I have no problems using an OVF. Perhaps with my glasses in the way, the distance between the eye to the viewfinder is compromised in some way so that I cannot see the whole image clearly... I dunno.
