Latest Review Posted Tamron Adaptall-2 SP 500mm f/8 Mirror (55BB)
This is the 3rd 500mm Mirror I have got. The first one was riddled with fungus and not sharp at all, the second was a Opteka 500mm which is very small for a 500mm but average sharpness (although usable for some uses) and really tricky to focus. Then I saw a Tamron for sale and went for it.

Its a lot better than the Opteka and a lot easier to focus too. For me Tamron is a viable telephoto that I can carry due to its compact size and light weight (for 500mm at least). Contrast is not super high but thats a mirror thing in general.

Bokeh can be an advantage and disadvantage. For a start, in the many scenarios (depending on background and distance to background) the bokeh is fine, and when its painting donuts sometimes that can work well in photos too but then it depends on the scene and your point of view.

Overall I'm pleased to have it in my toolkit.

Some samples:
