Interesting development - similar to the Contax AX but let's hope SF is quicker.

Sony's where it's at. If the promises come true.

There's suggestion from Sony management that an alpha 7x will be out in Q1 2015 that's designed for sports togging. This could also be either a 46 or 54mp 35mm sensor. AF to cover 78% of the sensor area. Well over 2000 AF points!

So small, wild resolution and very, very fast AF with high fps count.

The A7r is small, with good resolution (depending on shutter speed/vibration) and is infuriatingly slow. Slow to switch on. Slow to focus. Slow frames per second. Refuses to focus in low light. Clunky and bizarrely loud shutter which often kills resolution, lossy RAW (why?) and the battery life of a firefly. Should not have gone to market in this condition. A7s doesn't record 4K internally and requires a third party external 4K recorder that costs £1300 and still isn't available.

Promises, promises. Don't believe the hype.

Still much prefer shooting with the Pentax K-3. By a country mile. Like miles and miles.

Here's a good Sony rumour . . . the A7r MkII, coming January 2015.
