Excellent peroducts
The adaptor is very good. the 0.35x is a great match for my 1/2.5" camera sensor. Good image quality and no vignetting. The focus adjust is nice and smooth. Attached easily to the camera port on my microscope. Only problem is that it did NOT come with the C to CS adaptor ring that is listed and unfortunately I need that to get my camera parfocal with my eyepieces.
Excellent Product.
