    Re: Sironar N 120mm

    Cruising around the web a bit just now, I can find three pictures of 120's in Copal 1 that have all serial number digits legible. Adding mine, all of the S/Ns are within the range 106040xx - 106042xx. Four is a pretty small sample, but I'll go out on a limb and speculate that that production run was fewer than 300 pieces.

    I recently purchased this Copal 0 version


    and just developed the first film shot using it on my Horseman VH. Nothing printed yet, but examining the negatives with a loupe shows it to be very sharp. Typical of used lenses from Japan, it was slightly musty. A 1+1 chlorine bleach / water wipe down cured that. I'm very confident it was in its original shutter. The cells were tight and required substantial torque to break loose; the factory shim was in place under the front cell. Given the lensboard and missing rear cap, it probably sat in someone's medium format Horseman view camera since original purchase.

    This focal length is perfect for quite a bit of my work. With a 40.5mm front filter, it closes inside my VH. For anyone still interested, the rear cell outer diameter is 37mm. It is slightly flared, as opposed to the straight rear cell on my 100mm Apo Sironar N.

    Sal, that looks to be in good cosmetic condition. Thanks for bringing this thread forward. I also noticed the mystery of the 120mm in both copal 0 and 1 and was about to inquire here.
    Was the subject shot at macro distant?

    Which one should I get? I am leaning towards Copal 0 with a smaller filter ring.

    No, it was my backyard "standard scene" from around 50 feet. The Sironar N / Apo Sironar N series was optimized for 1:20. I assume 120mm versions followed suit. However, I've seen no technical data which confirms that they did.

    So few of them turn up for sale, unless you need the small front cell to close inside a field camera, I'd say whichever you can find. Having used only one sample of the Copal 0 type, I've no idea how their performance compares.
