I bought a Nikon D5000. Back then I didn't know anything about photography, but it sounded like a really good intro camera. And so far it has been. I don't mind the DX format, and have invested in enough DX glass to see no reason to upgrade to FX anytime soon (but that's a whole other discussion). But now to the heart of the matter.
I am thinking about upgrading my body. Maybe to a D7000, or whatever ends up replacing the D7000 here in the relative future. The main reason I am thinking of upgrading is my camera's lack of in-body focus. When I bought it I was assured by the sales person that it wouldn't be an issue, that lenses without integrated focus motors were a dying breed, an outdated technology. But now I have been noticing that there are still a lot of nice lenses, especially some higher end or specialty prime, that do not have in lens focus motors, which would make sense because (as far as I know) all high end cameras had in-body motors.
So, are we heading to a future where all lenses have the ability to AF, or will there still be lenses aimed at professionals that do not have them, based on the assumption that the camera they have does have an in-body focus motor. I also had another though that, theoretically, not having to integrate a motor into the lens would cut down on cost, therefore leading to cheaper lenses. Under that theory a body with an built in AF motor would pay for itself. Of course I realize that the price of an object isn't determined by how much it cost to make, but by how much people are willing to pay for it, so that isn't always the case. I did some research, and found some other questions on here about it, so it doesn't seem like either AF system has any inherent advantages over the other, so it seems like it would really be based on targeted customer (professionals are willing to spend more on lenses, and should have a body with built in AF already).
But, back to the point, the question is, will most (if not all) new lenses come with in lens AF, or will there always be lenses without it, making upgrading to a new body strictly based on that a wise decision?
