    Hasselblad's aversion to red dots

    Well, it's possible, but putting the dot on the side is like pre-computing a result you need often (if you change lenses), and so is efficient coding.

    Hasselblad's aversion to red dots

    I'm fond of the Leica Q for that reason. 28/1.7 Macro. Stunning lens.

    Hasselblad's aversion to red dots

    Huh! Didn't notice the lens contacts. Nice! Another Method! Thank you.

    Hasselblad 24mm (or 25mm) f2.5V and 135mm f2.5V

    Ah. Cosine to the fourth, and very clearly explained. I was aware of mechanical vignetting and cat's eye bokeh - it's hard to miss, but natural vignetting is less obvious. Thanks!

    Was the second image taken with the Speed Graphic? 😆

    Hasselblad's aversion to red dots

    The XCD lenses have NO protrusions or windows. They’re smooth except for the focusing ring. The new V lenses have a switch, but I don’t have any yet. Your UV glue method would be necessary. (And is a good idea for tactile feedback.)

    Hasselblad's aversion to red dots

    An invisible XF. I like it. I'm picturing an 8x10 Deardorff with black tape over the nameplate. People don't notice me when I put my tripod down next to them and quickly focus on the ground glass, insert the film carrier, take out the dark slide, and *click* for a candid portrait. :ROFLMAO:

    Hasselblad's aversion to red dots

    Yeah. the "hard to grab" bit bothered me a lot at first. Now I circle the base of the lens with thumb and first finger, press the lens release with the side of my finger, and twist. Seems to work well. A thick rubber band would also help.

    Hasselblad's aversion to red dots

    I do that with the rear caps. Of course, it means keeping them straight, but I also don't lose them that way. I tried putting labels directly on the rear elements, but it didn't work out so well.... :unsure: Matt

    Hasselblad's aversion to red dots

    I just spent an hour sticking little triangles onto the barrels of all my XCD lenses and adapters. Why? Because Hasselblad refuses to mark how to orient the lens for camera attachment without removing the rear cap, rotating the lens, and squinting until the tiny red dot shows up. The V lenses at...

    Hasselblad 24mm (or 25mm) f2.5V and 135mm f2.5V

    That's really interesting. I never thought about how vignetting could act to effectively reduce the aperture far from the center. Actually, even with a pinhole, it's pretty clear. The edges are further from the aperture, so its angular size is smaller. There's also the aperture appearing...

    Hasselblad 24mm (or 25mm) f2.5V and 135mm f2.5V

    And for a sense of ho much distortion correction is being applied, Hasselblad publishes the uncorrected distortion Here's the XCD 21/4 The XCD 25/2.5 And the XCD 28/4 The 21 and 25 look quite similar (and complex). The 28P's is smaller and simpler. The XCD 120 Macro, focused at 0.8m, has...

    Hasselblad 24mm (or 25mm) f2.5V and 135mm f2.5V

    Since de-mosaicing screws up resolution anyway, I'd love to see tests done on a monochrome sensor. Then we could really see the tradeoff between trying to eliminate distortion optically and digitally. I was going to claim that the Leica S 24/3.5 was big and heavy and distortion free, but I...

    Hasselblad 24mm (or 25mm) f2.5V and 135mm f2.5V

    Yes, as does LR. The whole imaging pipeline has optical and electronic steps. They've just moved geometric distortion control from the glass to the silicon. Lenses with flat fields and no distortion are wonderful, but have other compromises, e.g., the SK 35XL issues with the latest Hasselblad...

    Hasselblad 24mm (or 25mm) f2.5V and 135mm f2.5V

    John, I never considered the 30 a wide. The 28 barely qualifies. 😆 . The reason that the XCD lenses have no smearing (except for my first bad copy of the 28P) is because they don't have to worry about distortion. I think the Leica Q's miraculous lens (a 28mm f/1.7 Macro? Ridiculous!) works the...

    Hasselblad 24mm (or 25mm) f2.5V and 135mm f2.5V

    Distortion correction looks a lot better than corner smearing from sagittal/tangential differences (my opinion only). Matt

    Hasselblad 24mm (or 25mm) f2.5V and 135mm f2.5V

    John, As a long-time user of both the XCD 21/4 and the Leica S 24/3.5, I can attest that the focal lengths are *very* different. Sure, you keep a heck of a lot of pixels cropping from the 21mm FoV to a 24mm, but using the 21mm is an exercise in "I wasn't expecting THAT" during composition. The...

    Hasselblad 24mm (or 25mm) f2.5V and 135mm f2.5V

    Preordered from Capture Integration. B&H has it in stock, and I could walk there (ok, it's a long walk - I'd take the subway), but I don't want to reward Hasselblad for the way they've been treating their dealers.

    Hasselblad 24mm (or 25mm) f2.5V and 135mm f2.5V

    f/2.5 at that focal length is going to be big and heavy. I'm impressed that they went for it. The Fuji GF 23 is f/4 and the Leica S 24 is f/3.5. Hassy has the advantage of correcting geometric distortion in post, so that gives them some design flexibility, but still... And that lens cap...
