Coming to the A-mount
In my film days, I used Nikon exclusively starting with a Nikon F. My first digital camera was a 3MP Kodak, but as soon as Nikon Coolpix hit the market I returned to Nikon. I stuck with the Coolpix as they increased in the megapixel count because I found the swing lens to be very useful. When Nikon abandoned that body style, I decided it was time to begin looking into a conventional body style camera and chose the Panasonic FZ50. My biggest objection was the small sensor size tended to render everything in focus, but when its replacement was introduced with only a power zoom, I decided it was time to move to an ASP-C camera with interchangeable lenses. I was happy enough with my FZ50 that I had time to carefully consider what to move to. The Panasonic featured an EVF and I was firmly convinced the advantages far outweighed the supposed better view with an OVF, so Sony’s introduction of the SLTs made my decision a no-brainer. I started with an SLT A33, and have since built a nice inventory of A-mount lenses. I hope you are correct in your assessment of the future of these lenses. Recently I’ve found another advantage to the A-mount is the availability of a multitude of Minolta lenses in excellent condition which has allowed me to supplement my lens stock with some very nice under $50 purchases.
