I have been asked by many of you to try to get some info about the autofocus speed. I asked around and the answer I got is that the contrast autofocus is very fast. At least as fast as the Panasonic GH1 / GF1 autofocus. But we will have to wait until the official NEX release to be sure of that.
Another question was how many frames per second both cameras do have.
A first rumor I recieved says that the NEX3 will have 5fps and the NEX5 7fps. But I still need to doublecheck that news.

Thanks!

We have to be very careful when we talk about leaks coming form China. But that one seems to be more reliable than others. The chinese store detail.zol.com.cn posted the Sony NEX3 and Sony NEX5 cameras. The only real news is that NEX cameras will use the “FW50 Special lithium battery”

Someone can confirm us if the specs are correct?
Thanks!

We just received the two pictures from an anonymous sender. He spotted the Sony mirrorless camera inside an asian pub!
The pictures shows the Sony NEX3. The lens is the 16mm f/2.8 pancake lens. As we told you days ago the lens is chrome finished and has a diameter of 49mm. The lens is bigger than the Olympus 17mm f/2.8 Lens (37mm) and the Panasonic 20mm f/1.7 (42mm).
UPDATE: A second source told me that “the main reason for in lens stabilization is the video mode, which is easier to implement with proper focusing, not to keep the body shallow. ”

Reminder: We expect two Sony mirrorless cameras to be announced on May 11. The NEX3 and the NEX5 will be very similar. There will be only minor differences between the two mirrorless cameras (The NEX5 has faster FPS and 1080p recording, the NEX3 720p). Both will be very aggressively priced compared to MicroFourThirds cameras.
Both cameras will feature the new 14 Megapixel Sony ExmorHD sensor.

Keep following us until the announcement on May11: On Facebook, Twitter or RSS feed

Resumee of all leaks and rumors:
- The latest official Sony video (gave us some details about the cameras like 1920x1080p recording)
- Sony promotes the mirrorless cameras for the FIFA World Cup
- The rumored specs of the NEX3 and NEX5 cameras

You asked me to update you about the long awaited Sony Alpha firmware update. One of my trusted soruces confirmed once again that in will come in May.

That comes very unexpected!
According to informations we received the Sony NEX cameras will be sold with an optional optical viewfinder. We have no details yet, but we are certain the viewfinder is not electronic!!!

The Panasonic GF1 and the Olympus E-PL1/E-P2 do have electronic viewfinder.
