Sony RX100 V Review: Preview I happen to be a fan of the RX100 series. As a matter of fact, the original mk. I got me started in Sony, then a mk. II, and I had the mk. I converted to infrared. So full disclosure, yes, I'm a fanboy. The RX100 series isn't perfect. The lack of an integrated EVF on the mk. I & II is significant (composing on the LCD in bright light is difficult at best), the menus are a kludge, the buttons are fiddly, and the Vario-Tessar lens is fairly slow on the long end. But the Exmor sensor is beautiful, it's incredibly sensitive to low light, and the optics are top-notch. When I need to travel super light, it's the camera of choice. If I need a camera with a faster lens and just a bit bigger, I reach for the RX1R.
