Yes Larry, it only appears at F. 25-32 on the FA 2.8 50mm Macro (and the
Tamron SP 2.5 90mm).
I've been told that the A and M cesrsin don't have flat rear elements.
Perhaps I shoul get an A -lens instead?

I would sometimes get something like that from reflections off the uv filter.
Could that be a reflection off the sensor and rear element? Does changing the
aperture change the size of the spot?

Hi guys
I sometimes get a blueish spot, when I use a macro lens.
