Hi,

the optics are AMAZING, really, as they are made with abnormal dispersion glass from LZOS. They optics are made in Russia and put into CF tubes in Italy. They are rare and I understand why....they are very difficult to make.
It was very difficult to find those 2 even here in Europe.

The 130mm is a quadruplet design and the 76mm is a triplet.
Can I post here the spot diagrams?

Catalin.
