    zeiss opton? planar? xenar? 3,5, 2.8?

    Can any members out there shed some light on the above lenses? I am looking for MF camera Rollei and notice these different lenses were used on the Rollei twin lens.

    From a user standpoint are any of these lenses more desirable than others?

    Thanks

    Not a Rollei user, but in general, Planars are nicer than Xenars, but they are very similar to Xenotars.

    Professor thanks,


    1. what was the lens on the folder I saw in your office...I thought it was 105 mm?

    2. Does the planar have better resolution?

    3. Does opton designate a formula?

    Thanks again

    Zeiss-Opton means the lens was made in Carl Zeiss's Oberkochen facility. So Opton really just referred to a location.

    If it's a Zeiss-Opton lens, it probably is a Tessar. The Xenar is more or less the same lens as the Tessar. It's the same design made by Schneider-Kreuznach.

    The Planar replaced the Tessar as the standard lens on medium format cameras and continues to be the standard lens for medium format cameras. In fact, the Planar design is really the standard lens for most cameras. Like the Xenar, the Xenotar is the Schneider version of the Planar.

    Either will have excellent resolution at f/8 or smaller. The Tessar (and Xenar) tend to give you round backgrounds when shooting closeups at larger apertures. The Planar doesn't.

    As long as we are talking about coated lenses and typical shooting apertures I would just go for the cleanest lens. Most classic Rolleis are heading for 40+ years old, so condition is a bigger variable than ever. I have used Rolleis with Planars, Tessars, Xenars, etc. over the years. All are great. Technique, tripod use, straight equipment and careful development are the real-world determinants of sharpness. If you are looking for simplicity, durability, portability, etc., then any clean postwar Rollei TLR should bring a smile to your face. If you are looking for monster blowups with shattering clarity, then a clean current Hassy w/Planar has better odds of meeting your needs. Basically, a 1999 Mercedes is more likely to perform well on a cross-country trip than a 1962 Rolls. Just one opinion!

    The folder I had in the office was a Voigtlander Bessa II (6x9) with a 105mm/f:3.5 Color-Heliar.

    Planars tend to be sharper wide open than Tessar-types (like Xenars).

    CZ Oberkochen used the name Opton during the period it and CZ Jena were engaged in a lawsuit over rights to the name Carl Zeiss. Basically, Optons are early post-WWII CZ lenses from Oberkochen. I've seen it applied to several designs, not just tessars, including Biogons.

    Cheers,

    Dan

    The shared knowledge out there is incredible-I do believe one could compile a book on any given photographic subject with this APUG family

    Thanks

    There are Opton lenses for the Rollei SL66 (SLR), so they were also made some time later than the early post-WWII period. There were even HFT coated ones, so they are later than most of my SL66 lenses. See:
