Yes, there is always a cost vs benefit tradeoff. I still recommend the cheap Vivitar/Komine unless you need the very utmost in quality. I should add that my tests were on an MFT sensor so the difference might not even show up on a FF sensor with big pixels. And my tests were done with a reversed macro lens in front, not a microscope objective.

Thank you for this thread ... based on your opinions and info I just got a

Vivitar 135mm by Komine (M42) for 65 euros Smile (like 70USD maybe) and the lens is in very good condition ...

If no ther it's far more simple to use than the Raynox 250 (125mm) .. no more that bucket of adapters and tubes. ...

I was really after a "tube" lens able to do less than 170mm without vignette .. (all my other zooms do)

Thank you
