What's NEX? – full first-look review
Although you will never achieve the kind of results seen with your Sony NEX-3, the technologies used in these cameras do filter down and more compact versions may be seen in the future in your Sony Mobile Phone, enabling you to take great images on the move. Continue reading to find out more about the camera system and its capabilities.
THE SONY NEX-3 & NEX-5 cameras are ultra-slim interchangeable lens models, referred to as ‘ultracompact’ or ‘compact system camera’ models by Sony. The lens flange to film distance is only 18mm, compared to 44.5mm for the Alpha system and very similar figures for all popular SLR brands.
The Leica M and screw mounts, with under 1mm difference between them, are 10mm greater than this at around 28mm. Screw mount Leica lenses can be adapted to M even though there is only 1mm difference. With 10mm difference, almost any lens ever made for any camera – even the Robot system, original Contax, maybe even the Pentax 110 SLR – can probably be adapted to fit the E-mount. In fact it will accept 16mm and 35mm (half-frame) ciné, C-mount CCTV lenses, and subminiature camera lenses.
You name it, the NEX will be able to do it. Telescopes, microscopes, endoscopes, whatever. And Alpha lenses, and MD lenses. There is even enough ROOM with over 25mm the spare to fit a true retrofocus format reduction converter – that is, a 0.66X optical unit which condenses the image from a full frame lens to fit the APS-C sensor. It is already done in the video and ciné world, and these converters have a wonderful bonus. Your 24-70mm f/2.8 SSM lens becomes, with a 0.66X reducing converter behind it, a 16-46mm f/2. That’s right – the same way a teleconverter loses you a stop or two, a format reduction converter gains you a stop.
