I rather like Micro Four Thirds. Currently I have three \u00b54\/3 bodies and a collection of both dedicated AF (autofocus) and adapted vintage MF (manual focus) lenses. Trouble with \u00b54\/3 is that whilst we are very well catered-for in terms of long lenses, there’s a bit of a vacuum in shorter ones. So I decided to rectify this with the purchase of a  Risespray 7.5mm lens, and tested it by wandering around the old English town of Havant.<\/strong><\/p>\n

Shortest lens I had before this was 12mm (that’s has the same effect as a 24mm lens would have on a standard 135 film or “full frame” camera). So this is quite an interesting experiment for me. Don’t let the bloody silly name put you off. Whilst “Risespray<\/em>” sounds like some sort of garden hose attachment, it is the same as the “7 Artisans” 7.5mm f\/2.8, but less than 2\/3 of the price. It’s a beautifully made lens too – all metal and glass.<\/p>\n

A focal length of 7.5mm is not as extreme as it may at first seem. 7.5mm on \u00b54\/3 is equivalent to 15mm on 135 – with a viewing angle of approximately 190\u00b0. Judging by the various on-line reviews, it seems this lens is particularly happy on \u00b54\/3 – though there are versions for other small formats too. So it’s bendy and a bit soft at the edges, as one might expect with such a wide angle lens, but not ridiculously so. Anyway, here are a few snaps from earlier today,as I wandered about the southern English town of Havant.<\/p>\n
