Hi, I'm new to this forum, but saw there were a few posts from A7S owners and users on here, so thought somebody may be able to help with the predicament I find myself in. I recently bought a Sony A7S, with metabones EF-E adaptor (Mark IV) and Sigma Art 24-105 lens. I'm having a lot of trouble getting the lens and camera to connect properly - Sometimes, the lens works fine and I can shoot long video clips no problem. However, a large proportion of the time, the set-up has several issues: 1. The aperture randomly jumps 1/2-1 stop either side of my current exposure. 2. The iris won't open and close when I change it in the camera. When it does, there's a 5-10 second delay until the lens catches up with the camera. 3. I have downloaded the firmware upgrade on my macbook, and when I open the app and connect the adaptor, nothing happens. I have also downloaded it on my iMac, and it won't even open, it just crashes straight away. I also tried downloading it on my girlfriends macbook, but it also won't open on there. Any help would be greatly appreciated. Thanks, Andy

Aspect ratios including 4:3, 3:2, 16:9, and 1:1. Limited to 29.97P for U.S and 25P for 50Hz shooting. Shooters have the ability to shoot in Cine Picture profiles with full-manual controls. No 23.98 or 24P in PhotoMode. The 1:1 aspect ratio with a 2x anamorphic is a native 16:9. Internal recording at 100 Mb/s. HDMI output is still enabled! Might be a huge advantage to shoot anamorphic with a ShoGun after all! Will the GH4 embed the 1:1, 3:2, and 4:3 in a 3840x2160? I'm noticing a completely different grain structure in PhotoMode... Shot a 16x9 in 3840x2160 in Movie Mode and a 16x9 at 3840x2160 in PhotoMode and the grain texture in PhotoMode shows signs of compression artifacts not found on professional video or film cameras. Sorry. It's almost as if the sensor is acting differently. It's possible to notice the grain-structure change in 10x LiveView. The codec already has issues with recording in low-light, as seen by Dave Dugdale's GH4 vs. A7S demonstration (Dave's video mentions how a white background in low-light causes strange codec issues... I'm in a similar circumstance and it's helping to distinguish the new noise-floor patterns). This new grain texture appears to be present at ISO 320 and above. The white backdrop is close to 35 - 45% luminance values and not 80 - 95%). Needs more testing and proper lighting. Also, I'm under a 5200k CFL and not a professional non-strobing video light. However, this may be distinguishable in future tests with proper lighting and at low ISO values. Keep an eye out for it. Other info about 2.0 firmware... - - No new Gamma Picture profile. - - No 23.98 in 4096x2160.

It looks like some Nokia Lumia owners are going to be in for a 4K treat. It doesn't seem like it is a continuous recording mode but if you can do 10 second clips that's all I need. http://www.wpcentral.com/lumia-denim-firmware-announced-microsoft Nice to see a phone company expanding video features through a free firmware update. It's amazing that a phone that launched for less than $100 on contract last year will get 4k for free. I wish Apple would take a page from Microsoft's book instead of making people pay through the nose for basic features tons of other phones have. I mean am I to understand you have to pay $300 ON CONTRACT just to get the only iphone that has an HD screen? Terrible. And still no microSD expansion slot?
