I am offering two (!) of those high-quality achromatic lenses by Minolta.
For a close-up lens, it feels quite heavy (weight 46.5g / about 1.5 oz.)
which is about twice the weight of a conventional close-up lens. The
reason is the internal composition: The lens really consists of two
single lenses which are cemented together (achromatic doublet).
This method has an important advantage: The colour dispersion near the
lens perimeter is corrected for two wavelengths. This reduces colour
fringes there and allows for sharper images.
Minolta No.0 / +0.94 dioptres As I have two of them you can choose:
(a) 49mm filter thread
(b) 55mm filter thread
The lens conveys a sense of quality and has no signs of use. The
glas surface is coated and without marks, scratches or other flaws.
In fact, I would rate it's condition excellent or as-new.
With an adapter ring, I used it on my SMC K105/2.8 and it produces
fabulous images. The image quality comes very close to that of a
"real" macro lens and is much better than from conventional
close-up lenses.
Asking 59 Euros plus shipping.
Both achromatic close-up lenses are sold. Thanks to the forums!
