The Sony NEX-3 and 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.

A mention of 16mm Minoltas reminded me that a few years ago I found a perfect kit – without outer box or instructions, sadly – at an antique fair. A daylight developing tank for the film turned up in the closing-down stock from Konica Minolta’s warehouse. I decided they should really find a new home together via the normal eBay route, but before they went, a studio shoot was needed to record them for our virtual museum.

IN 1998 Minolta published, for their 70th anniversary, a large poster featuring all the landmark cameras from their own museum and employee collections. Many of the cameras shown – all fairly small on the poster – were well used and worn examples. The original image-files for the poster, which we have archived, are of poor quality. They are Japanese inkset CMYK sharpened for pre-press, with very dark gamma. This page re-creates all the information from the original poster, complete with the photographs. This page has been updated so that each period now appears as a separate section – simply select the next page to move on after reading each one. Page 1 is 1928-39, Page 2 1940-1959, Page 3 1960-69, Page 4 1970-79, Page 5 1980-89, and Page 6 is the 1990s. If you know the period of the camera you want to see, go straight to the page.

65 x 90mm image, the first ever press camera with built-in flash synchronisation system manufactured in Japan. Editor’s note: at Icon, we owned and used an Auto Press during the 1990s. It was equipped with a rollfilm back as well as plate holders. The flash synchronisation worked, and the 105mm f/4.5 Anastigmat lens was sufficiently good to permit one commercial studio shot to be completed using the camera, though contrast and light transmission were both low. The camera has a folding sports finder (the wire frame) as well as an optical coupled rangefinder and an optical viewfinder. It was a copy of the German Plaubel Makina.
