Hey! You should know that Sony has released a newer version of this product: the Sony RX10 Mark III.
Sony impressed with the RX10, the first camera to incorporate their popular 1" sensor with a big zoom. The camera giant is upping the ante once again, adding 4k video, enhanced sensor technology and even more speed to their luxury super zoom with the RX10 Mark II.
The redesigned sensor in the RX10 II is stacked--technology that is one step ahead of the backlit sensors. Basically, the stacked sensor is divided into layers, which allows each pixel to collect more light. Translation: the stacked sensor will get you better low light images over a the same size sensor that's not stacked. The design is popular on small smartphone sensors and appears to (finally) be making its way into more advanced cameras.
That sensor has been paired with a new DRAM chip, which processes the information coming into the sensor quite a bit faster then before. That faster processing speed allows for an excellent burst speed of 14 fps. Of course, that fast processing also allows the RX10 to record 4k video for up to 29 minutes straight. While not the first compact to offer 4k video, it's a welcome step up.
But (cue your best Porky Pig impersonation) that's not all folks--the Sony RX10 II is has an amazing 1/32,000 maximum shutter speed. That speed will come in handy when shooting in very bright conditions and shooting fast action, like birds in flight. That speed is only available at aperture f/8 or higher though, with a maximum 1/1600 speed for lower apertures. Since that speed is there to help with bright outdoor lighting, that f/8 minimum will likely be a non-issue.
All of these new features are added on to what was already great about the original RX10, including a bright f/2.8 lens and an excellent super macro mode. The RX10 II is equipped with an 8x optical zoom too. While that may not sound like much next to the other 50x and 83xs in the super zoom category, keep in mind it's much easier to add a big zoom to a small sensor. The RX10 II offers the equivalent of a 200mm lens on a DSLR, which is a pretty good reach. Of course, cameras with a 50x zoom will offer much more, but with a lower image quality from the smaller sensor. The lens on the first generation RX10 was sharp even when using zoom, where a lot of cameras have significant drops in image quality the farther you zoom in.
We were impressed when we tested out the original RX10--the 2015 version looks to keep all the positives and add even more speed, higher video resolution and an improved sensor design. There's not much competition here, since most super zooms use a much smaller 1/2.3" sensor. The Olympus Stylus 1 comes the closest, offering a 10x zoom with a 1/1.7" sensor (slightly smaller) and a much lower price but not near as much speed. The problem? At $1,300, the Sony RX10 II is a luxury item. The Sony RX10 Mark II is probably the best super zoom out there--if you can afford it.
