Magnus: “I just saw the post about using the A7R as a sports camera and would like to share my experiences. I think it works great and regularly use my A7R with Sigma 70-200/2,8 and LA-EA4 adapter shooting floor hockey. It’s really not the fastest camera regarding auto focus and continous shooting but it works! For close up action I have my old A580 with Sony 16-50/2,8.
Here is a sample folder with pictures scaled to 4k (2160p height), most of them are ISO3200-6400:

This might be interesting too, It’s the same floor hockey team at the same arena shot with Tamron 150-600 and LA-EA4 adapter on my A7R. This combo sure gets waaay to close indoors but although its ISO6400 I think it works great:

Christian: “I got the opportunity to test my Sony NEX-5T in extreme conditions. I went for a 2:30 hour walk through the city and next to the Charles River. The temperatures were -24F (-31C) degrees with the windchill! I had to face a lot of wind when next to the Charles River, changing lenses was a challenge and quite risky for the sensor. The camera performed really well during this hike, I did not notice any change working in these temperatures. The screen, AF and battery worked perfectly well. Even if the grip is very small, I could still use it with my gloves but I must admit that it wasn’t very convenient. Against all odds, this little camera passed the extreme weather test!

New Sony A7s tests (Vice News shoots with the A7s in the dark).

Share

Vice News shot a series about Boko Haram and used the Sony A7s to record in complete dark scenes. You can see the full video on Youtube (Click here). That kind of reportage would be almost impossible to make without the A7s.

3Dkraft (article here):

“The video from the “Carnival of Venice 2015″ is now public. It was recorded with Sony A7S, Atomos Shogun, Zeiss FE 16-35/4 OSS and Zeiss FE 1.8/55. The wideangle clips shot from tripod show the real potential of this combination. Unfortunately, the handheld portrait shots moving around the masks show the loss of quality due to the lack of stabilization of the A7S and the FE 1.8/55 even after digital stabilization (warp) in post processing. Scenes like that require a glidecam, brushless gimbal and additional OSS for professional demands. Irrespective of these little technical imperfections, this video shows the art and beauty of the masks and the scenery in Venice Carnival. Beside that, the article shows some zoomable images taken out as single frames from the video showing the quality of the 4K recording (still in process..).

Sony A7s Supercut Review by Stronzvanderploeg:

Overall the Sony A7s an incredibly specced camera especially considering the relatively low price point. If you need low-light or mirrorless full frame, it’s definitely the camera for you but just know, you’ll have to deal with a lot of workarounds and you’ll have to learn and adjust to some of the backwards design decisions.

Mark:

I’m a long time reader of Sony Alpha Rumors (I’ve been using Sony since the A900), and would like to pass on my recent experiments with combining the A7s with a Microsoft Kinect for a mixture of 2D video and 3D animation. I put together a blog article and some example videos showing how to combine the two devices using DepthKit software, and thought it might be interesting for your readers:

Kay Burn:

“My name is Kay Burn and I shoot photos and video underwater (and aerial work too).  
I recently housed my A7s with a Metabones adapter and the Canon 100mm f2.8 IS L in a Nauticam housing and used a prototype port and focus gear to shoot some macro video in the Lembeh Strait in Indonesia. I thought you might be interested to see how it performs;

Zeiss Q&A about the new Batis lenses (confirms in lens stabilization, made in Japan, unlimited OLED lifetime).

Share

On Facebook Zeiss answered many questions from their followers:

1) Yes, the Batis 1.8/85 has optical image stabilization
2) The displays are not limited in their lifetime. After many years of intensive use, they will become darker. If sometime they might be difficult to read, they can be easily exchanged by our ZEISS service.
3) Batis lenses use different components than Sony or Sony/ZEISS lenses.
4) Our Batis lenses are primarily made of high-quality plastics, aluminum and optical glass.
5) ZEISS Batis lenses are made in Japan.
6) MTF charts will be available in June.

Both lenses are now available for preorder at BH and Adorama:
Zeiss Batis 85mm f/1.8 lens in US at Adorama, Bhphoto. In Asia at Digitalrev.
Zeiss Batis 25mm f/2.0 lens at Adorama, Bhphoto. In EU at WexUK. In Asia at Digitalrev.
