Cinema5D (Click here) posted a full A7s dynamic range test (in video):

Here we tested usable dynamic range of the given cameras. With 14.1 stops the usable dynamic range of the A7S comes surprisingly close to the Arri Amira with its legendary Alexa sensor (see our full review here).
This is an extremely good dynamic range rating and is fascinating considering that the A7S is available at a fraction of the Amira’s price and is also in a completely different weight and size class. While the Amira will outperform the A7S in other tests, the dynamic range is a very important attribute to consider when working with a camera.

Gizmodo posted the full A7s review and writes:

The A7s is a great demonstration of technology powerful enough to make you forget about its flaws. The Panasonic GH4 has more tools, more options, more usability—with 4K built right in, and to spectacular effect. But the micro four thirds sensor of the GH4 offers its own compromises: low light is not very good, shallow depth of field is constrained, as is field of view. But here’s the real kicker. The A7s will literally increase the possible scenarios in which you can get a good shot, by way of low light performance. No amount of 4K, 8K, or how ever many K can accomplish that.

Techradar posted the full A7s review and writes:

Well, it’s an excellent camera, but still it’s one that has limited appeal. The average enthusiast is usually less concerned about low light performance and high sensitivity settings than pros who have to shoot in gloomy conditions. A professional wedding photographer, for example, might like it for its low light capability when shooting in churches and candle-lit receptions, but they are also likely to carry an A7 to enable them to take larger images (and therefore sell more expensive large prints) when shooting outdoors.

BBC cameraman Johnni Behiri posted his A7s review at Cinema5D (video on top). He writes:

The direct competitor to this camera is naturally the Canon 5D Mark III. Personally, I think it is time to move on and say goodbye to the Mark III. You now have an amazingly sharp looking video camera that records in a new robust codec (XAVC S), very small with a build in great OLED EVF and last but not least, also a lowlight king. I also have to had that the audio recorded directly to the A7s is much better then the one recorded on the Mark III because of better internal preamps. All in all, if you are looking for a working tool that is small enough to look “un-professional” yet one that records great looking video footage at a price which is not modest but affordable, look no further. The Sony A7s is your best friend.

Steve Huff also posted his full A7s review and writes:

For me, this is the camera to beat for 2014. So far, my pick for camera of the year. For me, if I add in the Voigtlander 15, Voigtlander 35 1.2 and the Sony 55 1.8 and I have a camera and lens combo that can do just about anything I ask of it, for my needs.

Meike Automatic Extension Tube For Sony E-Mount

Note: Although I had planned to do a image quality test of the sony a6000, I realized that I do not have a fair frame of reference, since I don’t own more than a couple bodies. Instead, I have decided to focus on reviewing the lenses and accessories, that are in my possession, at least until my other priorities take over (like, making a living for my family). I have decided to start with a budget accessory which could be quite useful to the owner of an e mount camera. This evaluation will hopefully be helpful to those who are interested in purchasing a product of this genre.

Introduction- Context and Competition:

Pentax 645Z bajo el agua

The chance is there that Sony will announced a proper new Sony medium format can fixed lens camera this year. And if that happens it will surely use that great new Sony 50MP sensor used by the recently newly announced Phase One, Pentax and Hasselblad cameras. So here is a roundup of test to see what such a sensor can deliver in terms of IQ:

Quesabesde posted some RAW image samples with the IQ250 if you want to pixel peep them and see what a Sony 50MP sensor can deliver you :)

SAR reader Eric Lo shared this A7s long exposure test. It shows the many hot spots you can see if you switch off the Long exposure NR reduction. We don’t know the reason why you have much more of them compared to the A7r. Anyway, the good news is that with Long Exposure NR on things look pretty good.
