Astro Berlin 2000mm f10 lens
There has been some controversy on the internet as to whether this lens actually exists, here's the proof that it does; https://www.ebay.co.uk/itm/256188891228 … R_KFuMulYw Some people have claimed that a photographic lens of this focal length would be impossible to make with the technology of the 1950s-1960s.. http://forum.mflenses.com/astro-berlin- … 68621.html ...but it seems they were mistaken.

There are four elements as far as I can tell, three at the front and one further back. Jan 22 24 06:40 am Link Nikon had a 2000mm reflex lens way back. Very expensive, the size of a small trash can and I never saw one other than in a Nikon FL comparison done by Nikon where they set up a model and photographers her from two miles away she on one side of the Golden Gate Bridge and the camera on the other with every FL Nikon offered. When they got to the 2000 they could not get a sharp photo and they attributed it to the smog in the are so they went to AZ, same two miles and sharp as a tack. Celestron also had a 2000mm Reflex lens sold as either a telescope or a T mount camera lens.
