Fifty years ago I bought my first professional camera, a black-bodied Olympus OM1 MD with 50mm f1.4 lens. Launched in 1972, its virtues were extolled by famed British portrait photographers Lord Lichfield and Lord Snowdon. The OM1 was the most revolutionary 35mm camera of its day, used by movie greats, rock stars and professional journalists alike. Which is why the salesman told me I'd be mad not to buy one.
My OM 1 travelled with me on some 15 expeditions, shooting mostly Kodak Ektachrome, and never failed once. Since then I have owned many cameras, although have no idea which particular camera was used to capture any image in my portfolio. I just grabbed any camera on the day to capture that fleeting image.
Typically I shoot portraits on medium format film (1974 Mamiya RB67 Pro S), landscapes on 35mm transparency film (1973 Nikon FM2n) and for commercial work, an iconic full frame digital (2008 Nikon D700). My daily 'carry', shooting 120 film, is a 1968 Mamiya C220 Professional Twin Lens Reflex with a 135 lens.
I currently have several art projects in hand which may need another 30 years to finish..
