5.0 out of 5 stars Quality Product
Operates as advertised attached to the Opteka 500mm preset refractor lens, with manual camera setting and adusting camera for varying light conditions. As with other Opteka products that I have purchased,the product is well engineered and reasonable in price.

3.0 out of 5 stars More Specification Please
While the 2x Multiplier delivers the image as promised, it would have been beneficial if it had been specified that the T-mount adapter was non-electronic sensing. Meaning I had to use manual adjustments on my DSLR for it to detect and use the lens, and not get the automatic functionality of the camera I paid for. I think specifying that would be beneficial.
