Sony has unveiled the NEX-3 and NEX-5 mirrorless interchangeable lens cameras. The two cameras are both built around the 14.6 megapixel Exmor APS HD CMOS sensor announced at the PMA 2010 exhibition in February and the new, mirrorless E-mount.

I look forward to Canon & Nikon's future offerings :)

LCD viewfinder :sick:

LCD tech still has a lag and can't be used properly in bright light...
 
I can definitely see the potential, although the form factor would take some getting used to, but unless they figure out a way for me to utilise my existing lenses I see little chance of my ever having one.
 
What bothers me more about the no mirror thing is that it does not actually have a shutter then ? oh well took me a while to ho DSLR from film and kicked against that for a while lol... so who knows where this will go...

Do we really still need shutters on dSLRs?

I can think of a few reasons just off hand...

Most notably dust being a huge issue with no shutter (I am sure they can put some sort of cover over it)

More importantly the sensor itself then needs electronics do tell the sensor when to capture this could add noise and will add to complexity of the sensor, also if you use the sensor for doing the viewing it cannot be as sensitive as it can be when it sits behind a shutter.

Third thing is the metering... this is a problem as the surface of the ccds reflect light where the shutter curtain does not.
 
With or without a shutter dust is an issue with cameras that have removable lenses.

Why isn't the sensor doing the metering itself? Because there is a mirror?
 
Traditionally the metering was done by a separate sensors... if you use this in a DSLR and remove the shutter the reflection from the sensor will be an issue... the next thing to consider is auto focus and how this will be affected... but I am not sure maybe they can do metering etc with the censor itself...

Removing the shutter can also be very positive... you can have any shutter speed you want, no more shake from the mirror or need to use mirror lockup for long exposures... will be interesting to see where this goes....
 
Do dslr's even have shutters? As far as I can see, all the shutter drive does is to lift the mirror.

If you look inside the camera, you can see the sensor under the mirror, as the mirror does not completely close off the sensor as it did in a film camera (the main reason for the problem with sensor dust).

I cannot speak for all DSLR's but Canon EOS, Nikon D series all have shutters...

And then there is the noise which I hate, in a quite environment it sounds like crackers going off and also makes people conscious of the camera especially for candid shots.

And then there are also Rangefinder cameras...

They already do - in live view.

There is definitely a shutter in my canon dslrs. You can see it if you manually lift the mirror.
