Hugo Meyer & Co-Görlitz Doppel Anastigmat Veraplan 1:4,5 16,5cm

[MichaelRelguag]

When I searched for a Skopar 4,5 13,5 for my Bergheil 9x12cm (I perfer the Skopar insted of the Heliar ;-) ) I came across a set of 4 lenses in dial-set-Compur shutter.

Voigtländer Anastigmat Skopar 1:4,5 13,5cm Compur 1- The one I searched for.
Agfa Solinear 4,5 13,5cm Compur 1- Agfa "Tessar-type" for their 9x12cm folder

And 2 unknown.

Zeiss Ikon (?) / Contessa Nettel Doppel Anastigmat Citonar 4,5 13,5cm Compur 1 and Hugo Meyer & Co-Görlitz Doppel Anastigmat Veraplan 1:4,5 16,5cm Compur 2

Could somebody tell me something about these 2 lenses - where they have been used (camera model) and what type of lens they are?
Might they be worth to keep them or shall I sell them? I don´t care for the value - got the Skopar I wanted for a very good price and these 3 are extra so money don´t count in this part for me.

I´m thinking of buying a 4x5" cam in the near future - maybe a Graflex Speed Graphic or a nice field cam. Shall I keep them a a ground stock?

The Citonar is a dialyte 4/4 type. The Veraplan is also a dialyte I think, probably for the obsolete 10x15cm format.

Is it worth to try them or are they keepers anyway?

[Ian Greenhalgh]

Worth trying I think, dialytes are usually sharper than tessars but lower contrast due to more air-glass surfaces. I like dialytes a lot actually.

Thanks!
So the Veraplan could be a portrait lens for my Bergheil - and maybe the Citonar for harsh light landscape - good to know!

[Ian Greenhalgh]

Yes, dialytes work well in harsh lighting, their lower contrast becomes a benefit in such situations.
