You won't believe the results you get with this 100% plastic camera. I bought my Vivitar Ultra Wide & Slim (known as a 'Viv' in some circles) from eBay after years of lusting after one. It has everything required for anyone with a good eye to become an amazing photographer: absolutely no control over anything, fixed exposure/aperture/focus, no battery or flash; just put a film in and away you go.
Run some slide films through it to get that excellent xpro goodness. So small it can fit anywhere, making it a great ‘take anywhere’ camera. Completely made of plastic (including the lens), you won’t need to worry about it getting a bit beat or battered as this will probably add to your love of the thing.
Oh, and one last point: the mega wide 22mm lens means you get shots to die for.
