Rodenstock Rotelar 510mm F8.6 lens

[iksobarg]

Hello special lens friends,

I have a question as I've come across a contact who has a Rodenstock Rotelar 510mm F8.6 with a Pentax 67 adapter that interests me.

Does anyone know firsthand or any info. on the IQ and general performance of this lens?

Many searches little to nothing helpful.

Many thanks!
John

John, Hi

'The Lens Vade Mecum' has this to say:

"...Telephoto Lenses.
Typically these were sold under the trade name Rotelar. (App051)
Rotelar f4.0 100mm 5-glass telephoto Rod025.
Rotelar f4.5 135mm Rod026.
Rotelar f4.0 85mm Rod024.
Rotelar f5.6 270mm for Graphic XL.
The 2/1968 list shows:
Rotelar f4.5 180mm for 6.5x9cm It covers 120mm dia at f4.5 and 130mm at f22.
f5.6 270mm for 9x12cm It covers 155mm dia at f5.6 and 165mm at f22 so it will
be useful on 5x4in, especially stopped down a little.
Both seem to be 2+1+i+1+1 designs, ie 5g/4c, in Compur 0 and 1 shutters respectively"

which I appreciate isn't the same focal length that you mentioned

regards
