Originally posted by sas.quatch I'm interested in landscape photography as well as a backup wedding photographer as a future goal. I was looking at Pentax due to the prices of the 50-135 f/2.8 lens which is much cheaper than the Nikon 70-200 f/2.8. The reason I'm moving away from the D60 is because of the limited choice of lenses I have to pick from that suits my budget.
I agree with Johnmflores, if you are not minding bigger camera bodies like D300, you may be better off staying with Nikon since you already have some lenses. But if you are looking for something more "stealth" and easier on your shoulder when you travel, Pentax K-7 and Olympus E-3 (though I am not too hot on the ergonomics of this one) are the ones that you may want to pursue. Either way, before you are fully commited, you can always sell the equipment and move on.
