I began using Minolta cameras and equipment and thankfully, when Sony took over, the fitting remained the same, so I have a modern Sony A77 and still use my Minolta lenses which are thirty odd years old. Thank you Sony.
I have recently stepped up to mirrorless by purchasing a Sony A7 and have lens adapters.
In medium format I have a Bronica ETRSi with an assortment of lenses and accessories which I use mainly for Black & White.
Most of my photography is of travel subjects and photo-journalism although I enjoy sports photography when I have the opportunity.
