Soligor 80-200mm f4.5 C/D
This lens has strong positives and strong negatives. I was hoping it would be as good as the 28-80 C/D but it isn't.
First, the positives: Wide open in macro mode it is sharp and usable. Macro with this lens gives a separate focusing range of approx 12" to 6 ft @80mm. It is sharp and mostly free of distortion with little to no vignetting and fringing in macro mode.
And the negatives: You will see purple fringing and stopping down has little effect on it. Vignetting is excessive at 200mm. Backlit images suffer from a pronounced reduction in contrast. It is worst at 200mm. Stopping down helps but contrast is never good.
And, the neutrals: Contrast is low across the entire zoom range and in macro mode. The glass itself is capable of producing sharp images but the design hinders its performance.
Conclusion: If you need a cheap macro for flowers and lichen, etc., this lens will please you. If you are looking for a sharp, general-use telephoto, you are out of luck.
Note: The copy I tested was made by Sun Optical.
