Mike, what is the possible flaw?
Steve
Hello Steve, I assume you're referring to the PK/A Adaptall-2 Mounts, on occasion these mounts will read as F4.0 instead of F3.5 or brighter on a faster than F4.0 lens, there are some fixes and tricks to make them work again, a quick search even on these forums should get you those answers. The lens will still shoot at F2.5, F2.8, F3.2 and F3.5 but instead of whatever the base aperture is of the lens it will show as F4.0.

So on a 300mm F2.8, if it has this flaw the camera will see F4.0 when you're shooting at F2.8, F5.6 when you're shooting at F4.0, it still works but you'll have to keep that in mind, or as suggested above look up the fixes for this flaw, most of the time in my experience the fixes work.
