    Long live technical cameras and digital view cameras!

    *** The thread started out with a pessimistic title but I changed it to one that better captures where the story went *** An interesting side conversation got started about the future of medium format photography based on technical cameras in another thread. Rather than divert that thread I...

    Getting the best performance

    I've been adjusting my lens lineup over the last couple months. One of my goals was to lighten the load as much as possible, without giving up quality. There was nothing wrong with the lenses I used last year; in fact, they were and are excellent. But they're a bit bulkier and heavier than I...

    Lens calibration PSA

    Consistency and repeatability are very important when you're evaluating lenses or adjusting a lens. Everything needs to be squared up properly, and you don't want to move the camera between test cycles. Occasionally random variables like this will mess things up. If you have one of these random...

    Toyo VX23D memories

    There's a Toyo VX23D outfit for sale on eBay right now. I owned three of these cameras. Seeing a beautiful copy like the one this person is selling, with all the trimmings, brings back memories. It's especially poignant because Toyo has now finally gone out of business. This is the camera that...

    Linos inspec.X L 60mm f/4

    There are some ongoing conversations (here and here) on the forum about the Rodenstock HR Digaron-S 60mm f/4, also known as the Sinaron Digital HR 60mm f/4. It’s described as a great performer that is not mechanically restricted on mirrorless cameras like the GFX system. Its main limitation is...

    Wide symmetrical lenses on Fuji GFX bodies: the case of the Schneider-Kreuznach APO-Digitar 35/5.6

    Mirrorless medium format cameras from Fuji and Hasselblad combined with digital view cameras from manufacturers such as Arca-Swiss and Cambo are an economical way to gain tilt, swing, rise, fall and shift movements. As with every tool, there are limitations. Notably, the flange distance of all...

    WTB: Schneider-Kreuznach APO-Digitar 35mm f/5.6 XL-102

    I have another WTB posting for an L-88 copy of this lens, and I'm still interested in one of those. But they seem to be very rare, so my next best option is an XL-102. If you have a Schneider-Kreuznach APO-Digitar 35mm f/5.6 XL-102 you'd like to sell, please send me a note. I'm in Canada...

    WTB: Schneider-Kreuznach APO-Digitar 35mm f/5.6 L-88

    I'm looking for a nice copy of an L-88 version of the Schneider-Kreuznach APO-Digitar 35mm f/5.6. This is the lens that pre-dates the XL-102 that you're probably familiar with. It has a much smaller image circle and was replaced soon after it was released because sensors were getting bigger...

    Lenses for Digital View Camera Outfits with GFX or Other Mirrorless Cameras

    I get asked a lot what lenses work well with digital view cameras paired with mirrorless cameras. When I get questions like that, I find it helpful to point people to a resource they can read to get started. When the question is about technical cameras with medium format backs, I send them to...

    Sold: Fujifilm GFX 50R plus accessories

    I've been storing my GFX 50R as a backup to my 100S, but it's time for it to go to someone else who will use it to make photographs. I purchased the camera new in mid-2019 in Canada, and stopped using it in 2023 when I bought a GFX 100S. It's been stored in a cool dry place since then. The...

    Rollei electronic shutter -- operation question

    I have a couple questions about the Rollei electronic shutter. If you've used one, can you help? 1. When a Rollei electronic shutter is off the camera, do the shutter blades stay open, or do they close down? Can it go either way depending on how the lens was set with the Control S unit? 2...

    If only you had 247 MP... What could you have done?

    There's lots of excitement about the possibility of cameras built around the upcoming Sony IMX811-AAMR sensor, which offers 247 MP. For example, see this thread: https://www.getdpi.com/forum/index.php?threads/new-sony-mf-sensor-in-phase-one.76352/ There are also folks in that thread wondering...

    Swing aesthetics

    I'm working on an image that used swing. The image is successful in the application of swing, in other words, I successfully put the plane of focus where I wanted it, and the wedge of acceptable focus that resulted included everything I wanted in focus, and left blurry the things I wanted out of...

    Flat field correction in Lightroom

    I use an LCC frame with images created with the S-K APO Digitar 35/5.6 L-88. From time to time, flat field correction in Lightroom simply doesn't work. There's no obvious reason. When this happens, I either fix the image with gradients, or run it through Raw Therapee, which works flawlessly...

    Behind the picture: share your thinking

    We have a long-running “behind the scenes” thread, which is a good way to share short posts about equipment. I thought it might be fun and interesting to start a “behind the picture” thread for sharing the thinking that went into one of your images. Posts should get into what you were trying to...

    Schneider-Kreuznach APO-Digitar 35mm f/5.6 L-88° on GFX

    Schneider-Kreuznach sold the APO-Digitar 35mm f/5.6 in various housings, and in two models, the well known one being the later XL-102° in a Copal 0 shutter. Much less common is the L-88° version in a Schneider-Kreuznach electronic shutter that is screwed to a lens board for the Plaubel digital...

    Image circles and shift spreadsheet

    I often see posts where people are wondering how much they can shift using a particular lens and sensor. There are some nice tools out there already for well-known combinations of lenses and sensors, e.g., the DT image circle visualization tool. However, I've found it's easier to use a...

    Center Filters -- skiing off piste with the S-K APO Digitar 35mm f/5.6 XL

    Quick question: has anyone had any luck using the "wrong" center filter with the Schneider-Kreuznach APO Digitar 35mm f/5.6 XL? The "correct" options are the IIf (M52.5x0.75 thread, with M72x0.75mm front thread, 4x) and the customized IIg, I believe for the Alpa version (M67x0.75mm thread and...

    Your favourite “bang for the buck” lenses

    On a graph that had cost of lens on the Y-axis and performance of lens on the X-axis, the bottom-right quadrant would have low cost but high performance – in other words, lenses that offer lots of “bang for the buck”. Many people on this forum have lenses from the top-right corner of my graph...
