Pancolar design?

I just received my $50 (all-in shipping to my country) Pancolar 50/1.8 zebra today. It had some fungus under the front element but it was easy to screw off the retaining ring and have at it with alcohol and some tissue paper.

It looks uncoated. Also the rear group screws off in one piece (I think it's two pieces of glass in one unit) as there was also some fungus there, also got rid of it.

I've heard it said that the Pancolar is a Planar design. However it looks just like all my other conventional 50mm lenses (a double Gaussian design).

I have a Rollei HFT 50/1.8 Planar which looks totally different: the front element is concave.

Haven't had a chance to shoot with the Pancolar but it focuses very close (0.35m) compared to my other 50mm's (I don't have a Volna or Industar). The focus is kind of gritty as well but I think I'm going to like the close-focusing capability....

A) The design of the pancolar you have - zebra - is six elements in four groups.

Three elements at front, in two grops: the first element alone and the second and third in one group. (from front to blades)
The same in rear elements, only that the first and second are in one group and the third alone. (from blades to mount)

The fungus in the fronts element may stay: 1-In the external or internal surface of the first element; 2- In the external surface of the second element; 3- In the internalsrface of the third element. (from front to blades)

The fungus of therrear elements may stay: 1- In the surface, internal or external, of the third element; 2- In the internal surface of the second element; 3- In the external surface of the first element (from blades to mount)

B) This is not uncoated. It's single coated.

c) Your Planara is different, because the desig of it is: seven elementsin five groups. Four elements at the front (from the front to the blades) with the first of them curved - as the Icarex's Zeiss ultron . And three elements at rear (from blades to mount) in two groups.

Good lck. Rino.
