Hi all,

In my constant search for better, more versatile, and more convenient close-up options I recently came across a twin of this gadget (for a description, see this link: http://cgi.ebay.com.au/Teleplus-MC7-...-/230552253538 )

After trying it out, using an Asahi Pentax MX (film) camera together with a 1.7/50 SMC Pentax M lens, I have to say it is the nearest thing -in use- to a Takumar 4/100 Macro lens at a fraction of the price.

Very versatile, very sharp, very convenient.

For convenience, it beats the pants off tubes and diopters and makes a 50mm prime lens into a great walkaround outfit (although you do lose two stops of light).
