Hi, I have an K2 and MX along with several manual focus lenses: Pentax-M and Pentax K. I also have a new Pentax K-X with the kit lens.
When using the old lenses on the K-X, having to manually stop down (with the green button) every time I want to take a shot is kind of a pain (but doable). I also heard it is not that accurate when the lens is wide open. (UPDATE: Correction, it isn't as accurate as the F stop goes up.. I took a pic with it wide open and it exposed fine, but as I closed up the lens more (pressing green button each time) it got darker and darker..)
I read in the K-X manual that it will work with the Pentax-A lenses in all exposure modes. I am wondering if the meter readings are accurate at all f stops with these lenses. Also can I use these Pentax-A lenses on my K2 and MX?
What are the optics like in the Pentax-A lenses versus the Pentax-M and Pentax K lenses? How do the Pentax-A lenses compare to the K-X kit lens I got?
I am wondering if I should be investing in Pentax-A lenses instead of the older ones. I could sell the ones I have now and get the A ones. Or maybe I should be going with the Pentax-F lenses? Will these work on my K2 and MX?
Sorry for all the questions.
