I am keen for a lens at the moment and after doing a bit of reading I have a question that I need help understanding.
To start with, I am the type of person that likes to buy for now and the future. If I can spend a little more now for something that will offer flexibility in a few years then I have no issues with that as long as the money is not too much more.
Now, I am looking for a lens for my D80 and a prospective D7000 (or 7100 if it ever comes out). There are more and more cameras that are starting to use the full size sensor and I can see the level camera that we are looking at will start to get this size sensor within 5 years as manufacturing costs come down.
I do expect them to be high pixel counts and thus using a DX lens on them will still yield a great picture, just at a smaller one than if using an FX lens.
I don't know what the price difference is between the lenses yet, so this question my become null-and-void one I do that research. I am seeing people claim 2K for a 35mm f1.8 prime, but I am also seeing new Nikkor's DX lenses of the same spec that are <$200. If there is a price difference that great then the DX is the obvious choice.
So here is my delemma - do I buy a FX lens now for my DX cameras so that they are suitable for what I believe is the future or do I just stick with the DX lenses and deal with the issue as it come along.
