Originally posted by selfnoise So, does anyone have any strategies for coping with this uncertainty? Have you bought into a second system? Do these kind of thoughts affect what you decide to buy?
I think you should just get a camera to take pictures, and not as something to sell later. That being said, if you're thinking about other systems why not just have an open mind and try some new models at your local camera store? Personally, I don't believe in loyalty to any brand, but if you want to own the DA limiteds, just buy them.
As for myself, I have some Pentax gear and I plan on using it until it dies. Some of my lenses do have aperture rings, and I will just adapt those once my bodies stop working. I am also in the market for a few new lenses for specific purposes however, and for those I'm actually looking at other systems. However, the main reason for that is because of the capabilities of other systems/lenses that aren't available for Pentax.
For the purposes of photography, I don't think you should let the future worry you.
