    What is the FCS for? I have tried both on and off but didn't notice any difference on my 7's images. I tried googling it but got even more confused. Please help!

    It does effectively two things: Doubling the life of your mechanical shutter (because the first shutter plane is done with electronic scanning rather than a real shutter curtain) and reducing the shutter lag. If everything works properly, there's no reason to deactivate it.

    Oh I get it now! It's like mechanical vs electronic shutter operations right? When I did turn it off, the shutter sound was a bit louder I did notice. Thanks for the solid responses guys!

    I switched the camera to electronic front curtain almost immediately after I got the NEX-6 half a year ago and I left it that way since. I have never noticed any problems with uneven exposure nor blurry parts in the image, using a lot of legacy Minolta MF lenses alongside the native E-mount lenses with all kinds of shutter speeds and with or without flash.
    On the other hand I have the impression that I suffer significantly less from vibration this way and I like the low shutter-lag it brings, as mentioned by Poki as well.

    After to have been with you I have always used the camera with Shutter curtain front enabled.. No problems encountered. Find it more comfortable. Else also feel he makes two pictures sequentially.

    Hello Frank. I have a Sony NEX 6, for which I also bought the SEL 50mm F 1.8 lens. I use it for astrophotography. As to the Front Curtain issue, I was having too much shutter vibration, causing image focus issues (clear on the LCD and ECF but not so after playback). Enabling the Front Curtain has minimized this, but I still have some remaining to deal with. Since astrophotography will inherently show the worst of situations, I hope this may help others with less demanding vibration/focus issues. Thanks for your info and links on this subject.

    With a good tripod and a remote, shutter vibration shouldn't be a problem.

    Hello Poki. I have a very stable tripod, for my telescope and always use a remote (2 second timer). Before I switched to Front Curtain , There was always a significant difference in the focus between what is seen on the LCD screen or the EVF vice the played back image (less focussed). My Panasonic FZ 47 (P&S) does not suffer this issue. My Pentax KX DSLR has the mirror slap vibration issue )minimized with a remote/delay), which is why I went mirror less.
    Now the final image is much better, but I believe my NEX 6 still has vibration issues. When the weather is clear enough, I will attempt more images (stills and stacked videos). I will also try the Hand Held Twilight mode for some Moon imaging (I wish it was available in the M and S modes).

    Hmm.. interesting! I only do night landscape with wide angle lenses and no 'real' astrophotography, so that might be why I don't suffer any issues with my old NEX-5.
