K01/Tamron 500 f8 Mirror Test Shot

I played around with the K01/Tamron 500 f8 mirror and Tamron 2X TC today. An example is below. It is not great IQ but this is at 1500mm equivalent.

Here's one I took with that Tamron set-up on a K-5 last year.

These simple Schmidt Cassegrain mirror lenses are not very good which is a pity, cheap to make, small and light. I wonder why manufacturers don't use the much better Muscatov Cassegrain which have colour and distortion correction and give a much sharper image with higher contrast.
