    Re: Suter serial numbers and dates.

    I believe I have asserted that the Stella series is basically a continuation of the F.5 Rapid Aplanat series.
    I am pretty sure this is not the case!
    Not only do the sizes of the Stella not match...

    Re: Any info. on Suter lenses

    I have always assumed that the Stella is a rebadged Rapid Aplanet (F5) with Jens glass - as the offered focal lengths were an exact match.

    There is a 42 and a 50cm in the catalogue. I can see that...

    There are plenty of Thornton-pickard (T-P) curtain front mounted shutters available which would (and did!) work well with smaller Petzvals.

    Re: Old ICA lens question

    I am guessing that the F5.4 is a Goerz Scale rendering of F6.8! F.5.4 is pretty hard to achieve without air spaces in lens cells, which the OP hasn’t mentioned.

    Fungus is very unlikely for a non coated lens of this era.

    Is this mounted in a Compound shutter?

  10. Re: What is the good camera for wet plate photography

    A Petzval that covers full plate size will weigh up to 2 kilos, so what you have paid for postage should give you a clue. An RR will be under 0.5 kilo.
