It's been a long while, but I am finally in a position to consider purchasing a camera again and taking up photography ... and now I live right on the water- at the beach in SoCal. I was just going to get a Maxxum 7 again, as that was always my favorite back in Alaska. However, I just got to thinking...with the sand and the saltwater down here at the ocean, how important is a sealed all-metal pro type body, say more along the lines of a Maxxum 9 or Nikon F5 type body? Will it make any difference or even be worth the added cost of the body? Thanks for any thoughts on this one.
