www.robnunnphoto.com dSLR’s are great, but lenses are expensive, even second-hand ones. If you buy a M42 lens mount adapter on eBay, you’ve then got access to the thousands of much cheaper (and older) M42 Lenses. M42 Glass is manual focus, and you have tomove the aperture ring by hand too, but if you put your Canon dSLR into Aperture Priority Mode, it will meter the scene and set your shutter-speed accordingly. By adding extension tubes we can take macro or close up photographs, and the equivalent EF lenses are incredibly expensive, but we can get similair shots at a fraction of the price. So buy an M42 lens mount adapter, then trawl the flea-markets, charity shops and car-boot sales for M42 glass and extension tubes. Thanks for watching, Rob.
