    Rodenstock 138mm f6.5 HR Digaron SW FLOAT

    Well the Rodenstock 138mm f6.5 HR Digaron SW FLOAT is out. Looks like the focus (with floating lens element(s) is built into the lens positioned in front of the e-shutter.

    f6.5 sounds strange, maybe it’s a typo…

    Re: Rodenstock 138mm f6.5 HR Digaron SW FLOAT

    Newsletter from Linhof Studios:

    ”NEW Rodenstock 138mm f6.5 HR Digaron SW FLOAT

    This new lens from Rodenstock sets new standards for the demanding and every changing needs of digital photography.

    An exceptionally sharp long focal length lens for adjustable technical cameras intended for a wide distance range from infinity
    up to an image scale of 1:5 (β' = -0,2).

    It provides negligible distortion (almost always below 1‰) and a total suppression of the chromatic aberration for perfect freedom from colour fringing.”

    Steve, how big/heavy is this thing?
    This looks like Alpa mount, is it available in Cambo WRS too?

    I don't have exact dimensions, but it is a beefy lens.

    It will be available for Cambo as well as Arca Swiss (and standard lens boards for various view cameras).

    Steve, what you have pictured looks like an Alpa mount at the rear a helical and an E shutter. That's where all of the bulk comes from. The actual lens, which I would only be interested in, with just an aperture would be much smaller.

    'Float' as in floating element, I assume.
    Don't think we've ever seen that in (essentially) a Large Format lens, have we?

    I'm waiting for Alpa's announcement, in hope of a non eShutter solution. Besides ES, Alpa have the FPS/Silex shutter unit, so that's 2 reasons why it's redundant. A pointless and pricey addition. Hopefully they will offer a slimmed down option.

    Though... who does make a simple aperture unit anymore, that could be put in there?

    I missed that Alpa have updated the Silex to Mk2, that works with the eShutter, acting as control & power unit. So they may regard encouraging that option as a way to sell more Silex, and not the other way around. Sigh.

    Simply can't do the work I do with a 1/250 top speed, need 1/1000 at least to freeze pedestrians. So this lens is useless with that shutter, for me. Appreciate that is not the case for others.

    Re: Rodenstock 138mm f6.5 HR Digaron SW FLOAT

    I've just finished up a Skype call and seen a prototype of a Rodenstock HR lens in the diaphragm/no shutter configuration. It is not quite final, so I cannot reproduce the screen shot I took, but suffice to say there will be something in the fashion of a tube to account for the spacing that the Copal 0/e Shutter would normally provide. I don't have a confirmed filter thread size yet for the 138mm, but it is a large heavy lens. Alpa provides 1.5 kg as the listed weight, and this is probably about 200 g more than the lens without helical mount. Rodestock lists the 90HR-SW as 680 g while Alpa lists it at 880 g.

    You have the option of eShutter, which can work with the Silex II (or a Sinar Controller), which will have some advanced capabilities in conjunction with an IQ digital back, or the aperture control only/no shutter included, and mount to whatever you like. On that same topic, I've had some ask me about using the eShutter with a view camera, like an Arca Swiss, Cambo, Sinar, etc, and this provides the same options of using an Alpa Silex II, or the Sinar eShutter Controller. In both cases, you'll need to account for placement of the controller, but you also can of course interact with a remote app to control the eShutter.

    An example of a previous large-format lens with floating element: The Rodenstock 105 HR as mounted on a DT RCam for high-magnification film scanning (e.g. 35mm slides scanned at up to 12,000ppi in a single capture, up to 15,000ppi with a quick 3-shot stitch) with our DT Film Scanning Kit.

    No need to wait for Alpa to announce... This lens is available with or without eShutter. When delivered without an eShutter a manual/mechanical aperture ring is inserted. You can contact your local Rodenstock dealer for more info or to purchase. If in the USA, we (DT) are glad to be that dealer for you.

    Obviously with just the aperture control only, there is no need for any controller, so you save on the cost/clunkiness factor, but you are reliant on the capabilities of the built-in eShutter of your chosen camera body or digital back.

    Thanks for update Steve. Looks promising.
    Glad to hear they recognise that a lot of customers don't want eShutter.

    Any ETA on the 'light' version arriving in Alpa mount?

    I would conservatively state 3-6 months, if I can get a more precise estimate, will follow up.

    Steve,

    Thanks for the information about the aperture-only configuration. Is there a manual shutter included to allow for a dark frame to be taken without resorting to fumbling with a lens cap?

    In the version I have seen from Alpa, yes there appears to be.

    Also, I have now some pretty rough iPhone shots of the technical data. Hopefully it will be legible to everyone here. While the filter thread is only 67mm, it still is listed at 1400 g, due to the dense and complex optical design.

    You almost have to get a ruler out with MTF charts nowadays to see whether the lines are perfectly straight or have still a bit of a curve.

    Most of the Rodies are between €5000 and €8000. The 105mm Alpa Switar is around €4500,-. If it is somewhere around there it sounds like a good price for a fancy piece of glass like this, but I would expect it more around the 8000 mark.

    I was told near $13,000 in Alpa mount w. just aperture/iris solution !! (not e-shutter)

    Just when you thought you knew what MF digital costs, they go and raise the game. Sigh.

    Apparently it's too heavy for a Copal shutter - they can't support the weight without losing alignment.

    Re: Rodenstock 138mm f6.5 HR Digaron SW FLOAT

    Landed US$ price will be around $15,500 for the 138 and the 105 US landed price is around $6750 now.

    This is based on my personal Alpa imports-exchange/duty/shipping and current Alpa pricing. I do not know if duties have increased this year.

    Personally finding a used/mounted 120/150/180/210 is worth the hunt.

    PS- Neglected to mention the Alpa SB 51 and lens hood are included in the above 138mm price.

    Crazy money for a lens with no stabilization, no AF and razor thin DOF.

    But I am sure it will sell.

    I don't undersdtand why its taking so long for the lens to be available since it was supposed to be available about 12 months ago.
    I wonder if Rodenstock just canceled it altogether.

    Rodenstock were taken over by Linos, in turn by Qioptiq who now appear to have been acquired by Excilitas, so all this may have delayed things. They do at least show an image of the 138 on their website, and the PDF says available from October 2019.

    Here's the PDF (link): https://www.excelitas.com/file-downl...20brochure.pdf

    Just a reminder that the 105 is available from Phase One Industrial as the Linos 5.6/105 float. Ex-Copenhagen price is around $4100.

    That made me chuckle too, but since Excilitas do a lot of work in the defence and aerospace industries I guess $15k is 'economic' for clients like that. Other than for specialist purposes (e.g. copying artwork, cultural heritage etc.), this seems bonkers for most photographers. A used 120 ASPH would be much more preferable in my book (huge image circle, lighter, simpler, less flare, superb image quality etc.)

    There are enough people looking for the 120 ASPH around these parts that maybe we could start a petition and convince Schneider to do a GetDPI run of lenses......pretty please S-K??

    I'm very happy to have one of the last new 120 Asph lenses and have no intentions of selling it. The 138 is a very different beast and will find a place in my arsenal. To me cameras are throw away..... lenses are forever.

    Based on the quantity that we (DT) have to order to continue having this lens made for our CH product lines (dtculturalheritage.com stuff), I think you'd have a hard time.

    Why reveal the lenses are still in manufacture, and imply they are available, to then turn around and say that the potential purchasers would have a hard time obtaining a new one if they attempted a group purchase? Why would you not try to arrange this yourself, as a dealer, by increasing your order size by a list of pre-purchased buyers next go round?

    I've appreciated your postings here as a lurker for many years, but this seems a bit of folly, perhaps. Nothing personal, I very much admire DT and yourself, but surely there is a way to connect future owners to an apparently still manufactured lens? Perhaps not. Can't always get what you want and all that.

    Who knows - maybe the Rodie 135mm elements take over a year to cool/settle like Leica alleged the Noctilux glass did?

    Thanks. [Interesting, still showing the Apo-Macro-Sironar digital.]

    The S/K has an IC of 150, the R/S's is 110. If you limit the S/K's to 110 (in order to make a comparison), then the angle of view is ~49 degrees, the R/S's is ~44 degrees. On a long lens those 5 degrees are hardly noticeable. Outside of highly specialist applications, I don't see any situation where you would reach for the R/S instead of the S/K (if you had both), unless you're a masochist and enjoy the workout of lugging a heavy lens any distance, and the jeopardy of dropping the behemoth.
