How Did I Miss the A7S?

Was in a coma for the past month or so? It's the only way to explain that I was only recently made aware of the awesome Sony A7S. You know how I said that ISO performance no longer matters? Well, Sony didn't hear me and instead built a camera with the best low-light performance ever. This bad boy is nearing 4,000 on DxOMark's database. Four thousand!

Obviously, the tweaking that the sensor required to get that high required concessions. The dynamic range and color depth are both lower than the other two Sony A7 cameras, and lower than most other top-rated pieces of kit. But in this case, I don't think it matters. If you are buying this camera, you have very low-light situations in mind, and a bit of color and range is a fine trade for better night shots.

Sony is also progressing on the video front, making this the best video A7 camera yet. Rolling shutter is still dreadful, but if you won't be doing those kinds of shots, then it's not too much of a concern. That said, the rolling shutter is pretty bad. I would imagine that the heat coming from the sensor is the limiting factor. The A7 body is crazy-small, meaning that it can dissipate only so much heat.

In all ways, this is an exciting prospect that opens up new areas of image creation. If you are a journalist looking for night-time run-and-gun video shooting, we've found your camera. Because I love the GH4, but like Hammer, it can't touch this.

Very impressive.
