Tamron 200-500/6.9 AD2 vs 500/8 AD

Hi, has someone chance to compare Tamron Adaptall 200-500/6.9 with Tamron Adaptall 500/8 mirror lens? Is there big difference in IQ? Trying to find more info on 200-500 but can't find any samples ;-(

Hi there. Can anybody advise? I know that 200-500/6.9 is not very popular, but maybe someone used it?

It looks like nobody has any experience of either of them. I don't recall anyone talking about them in the past.

I've used the Tamron 500/8 SP Adaptall mirror lens for a while. The lens is very well made, full metal barrel w/ a huge hood. Very small and compact for a 500mm lens. The lens performs pretty well under good light. It has a minimum focus distance of 1.7m (1:3 macro), very fun to use at such a close distance. If you select the background properly, you won't see the donut bokeh easily.

Here are some photos I took w/ the lens and K10D camera:

The lens is pretty sharp when focused properly. Here are some center or near center crops followed by its full size photos:

The lens can produce very good results (to my standard) with creamy smooth bokeh too:

Hi Frank,

thanks a lot. This 500/8 looks pretty good. I'm looking mostly for oppinion on T200-500/6.9 in comparision to 500/8. Seems to be rather not so popular lens.
