BTW=By The Way...

The lenses that Changling is talking about will not fit your Dynax 5, without an adapter, they are great lenses, but you are talking about a Dynax/Maxxum System the SR series is the older Manual focus system, great stuff..but for us that are older, a bit more difficult to shoot, I still have a couple of XD-11's and alot of great lenses.
