I'm happy to hear that you got this in the end.

 

I am personally very happy with it especially for the reason that I can use it both for macro and to adapt lenses without any helicoid.

 

Lately I use it also on an Helios which had lost the last part of the focussing barrel (still has the internal helicoid) and in this way is adapted to Fuji and focusses very easily too.

 

Of course there are disadvantages in using an helicoidal extension macro tube since the light diminishes with the square of the distance you are pretty soon losing light like hell ( at the speed of light!) when you get very close.

 

Did you have to pay any tax?

True ... but it beats using tubes. I found some beautiful Minolta Achromatic Close-up lenses (not those thin ones you see everywhere) for a few Euro so I'm probably going to alternate between that and the helicoid adapter for the coming time.

 

Nope, no taxes! The price was on the outside of the package. It said "Lens adapter. Value: 3.00". That is such a low value that Belgium customs probably let it slide.  :D

yes, they do that often, of course being a very small item this helps.

 

Interesting the achromatic lenses. I have found one Sigma Achromatic macro lens too but it appears to be just a close up filter like many others there is no indication of its dioptric correction. Maybe I will find something better one day.

 

Macro photography is not something I practice a lot but it is nice to have some extra macro capability.

Here's a list of currently available achromatic close-up lenses.The Minoltas don't really have high diopters but it's more than enough for me. I'm not really into super macro. It's just nice to get closer to a little flower with a Super Takumar 55mm 1.8 lens, for instance. The helicoid adapter is downright perfect for that.

an enlarging lens would work well for macro ( better so on an helicoid than on a macro bellows which makes the ensemble rather more heavy and difficult to operate) because corrected for short distance, some would work better than others ( like old Leica and Agfa lenses and old Componons) because of their circular, sometimes stopless, aperture. Some lenses are also apochromatic.

 

The drawback is the aperture relatively slow of most enlarging lenses and the size of lenses longer than 150mm, but shorter lenses than that are very small and light.
