Bit boring to say always high quality lens, superb built quality.

It is mountable on any micro 43 camera bodies (Panasonic,Olympus).

During the early 1960s, no one but AsahiPentax did build similar lenses (first a 2.335mm and later a 235mm).

The Nikkor 235 mm came out in 1965, and the Minolta Rokkor 1.835 mm was following in 1968.

It is interesting to note that the lens section of the Nikkor 1.435 mm (1971) looks very similar to the Hexanon AR 235 mm (the Rokkor 1.835 mm, widely seen as the best fast retrofocus wideangle of its time, has completely different origins; it was modeled after the Schneider 2.835 mm).

Typical for most Hexanon AR lenses, focusing is quite stiff, and the aperture ring is a pain to use - especially if you compare it to the conteporary Minolta and Leica designs.

As a result, the wide op en performance of even the newest AR 235 mm lenses is rather mediocre: Its contrast is low, and theres a lot of smearing towards the corners.

In other words: it is a typical 1960s lens with a lot of character.

To some extent, these characteristings remain visible even at f4 and f5.6.

Usually, however, about CHFEURUSD 60-120.-- are being paid, depending on the condition of the item.
