We got to play with the Sony Alpha NEX-7 with the black 18-55 mm OSS lens at Unique Photo in Fairfield, NJ so we wanted to test out the new shutter. Here is a video of the NEX-7 shooting in Speed Priority mode at 10 frames per second then in Single Shot mode. Next is the Sony NEX-5 at Single Shot, then at 7 fps. The venue was packed so the shutter sounds are not isolated.
As you can hear the NEX-7's shutter sound is much gentler and cleaner than the NEX-5. The NEX-7 had the Front Curtain Shutter option ON. This is similar to the NEX-5N, which may affect the sound slightly, maybe someone with a NEX-5N can clear this up for us. We've read that the difference is barely noticeable.
We wish we had more time with the NEX-7. There were a lot of people interested in the 7, 5N, and C3. We will have more posts from our trip at Unique Photo. Thanks Unique Photo and Sony USA.
