The company has its own website: http://www.un-ltd.co...rs/index05.html
I doubt Dyron "outsource" the manufacturing of its lens to this UN brand company. If they do, at least they would stamp the Dyron name on the lens.
The manual say it's x6 magnification, Bluewater's site say it's +7, confusing right?
This is my first macro lens so I don't know what to expect and I can only tell its quality after I use it. The plan is to get a Subsee +5 in the future and stack the Subsee on the "Dyron".
