Hasselblad SWC is cool

If anyone is looking for one Usedphotopro currently has two of these for sale and they will have 6 month warranties.

Speaking of the SWC and the implied need for 120 film scanning, I saw this today:

https://www.negative.supply/

Interesting things … These folks have a pro-grade 35mm carrier designed for copy camera film scanning and are working on a similar pro-grade quality 120 carrier. A pro-grade film carrier for 120 format scanning would be very nice indeed and would make 120 film much easier to work with... I've bought into the Kickstarter on that project.

If the quality matches what I see in the 35mm product, it is worth the price ... but it's fairly pricey.

They list what you need at the bottom of the campaign page in the "What do you need for camera scanning" section: Negative carrier, light source, camera stand, and camera with an appropriate lens. You can go as basic or as high-end as you want from this stuff...

The negative carrier is the basic part that's the subject of the Kickstarter campaign (and they have a couple of additional accessories for it like the Pro Mount and Negative Brush, etc).

Light source is a light box of whatever tech you want that will support the weight of the carrier assembly. I have an ancient flat panel light box; I'll probably get a new one sometime soon, they're a lot better now at far less money than when I got this one.

Camera stand is a copy stand or tripod to hold the camera. I use a very nice Novoflex Magic Stand and a Novoflex focusing rail, with Arca-Swiss type QR mountings. Expensive but very versatile in that it can be set up in a variety of ways for different tasks AND folds small and flat for storage. Negative Supply is making a very nice copy stand accessory too, dedicated to the needs of film scanning.

Camera and macro lens ... My present copy camera is the Leica CL for which I have several different lenses, bellows, and ELPRO close up lenses for a variety of different copy work and tabletop needs. It nets a 24 Mpixel image of 35mm FF negatives and a 16 Mpixel image of 6x6 negatives, generally speaking enough resolution and tonal scale for anything I want to do in prints.

The advantage of a well made, precision negative carrier over simpler/cheaper negative holders is that once you set it up, you can do an arbitrary amount of scanning very quickly and know that your negatives will register accurately and be flat, you won't have to reset focus, etc, for every frame. Makes a big difference towards the scanning work a pleasure rather than a frustrating, time consuming PITA. 😀

Beautifully crafted and thought out. Quite expensive.

Was wondering if any body could comment on the Voigtlander 15mm Heliar II for M mount output vs the Hassy SWC?

There's no comparison ... the SWC's Zeiss Biogon 38mm on 6x6 produces FAR better quality (better detail resolution, better contrast, much less light drop off, etc) at corners and edges, and it has virtually no rectlinear distortion.

That's not to say the V15 lens is a bad lens: It's just not in the same class as the Zeiss Biogon.

What about the Voigtlander 12mm MkIII? Crop it square and you'll have the same 90-degree angle of view as the SWC.

Actually, a square crop on FF with a 15 to 17 mm lens is closer:

Angle of View

SWC
Width = 56 mm, Length = 56 mm, Diagonal = 79.196 mm
f - Hor/Vert - Diag
38 - 72.8 - 92.6

FF cropped square
Width = 24 mm, Length = 24 mm, Diagonal = 33.9411 mm
f - Hor/Vert - Diag
10 - 100.4 - 119.0
12 - 90.0 - 109.5
15 - 77.3 - 97.0
16 - 73.7 - 93.4
17 - 70.4 - 89.9
​

I haven't used the 12mm lens. I have the Voigtländer 10mm, which I crop square on the APS-C format for a similar FoV as the SWC:

APS-C cropped square
Width = 16 mm, Length = 16 mm, Diagonal = 22.6274 mm
f - Hor/Vert - Diag
10 - 77.3 - 97.0​

It performs very nicely, but doesn't give the same results: it's a wider view and has more than three stops of additional DoF at any aperture/distance setting compared to the SWC.


Leica CL + Voigtländer 10mm f/5.6
ISO 100 @ f/8 @ 1/160​

The fundamental truth of the matter is that if you want the SWC rendering qualities, you need to have an SWC. Each camera/lens/format combination is unique. 🙂

So did I.

That's what I think, too ... pricey but worth it when it works as well as their 35-mm film carrier. I guess that's the price to pay when a well-designed item is produced in small quantities and pro-grade quality by a small start-up ...

Yeah, it probably is ... but had you pretended the above picture was taken with the SWC, no-one here could complain and prove you wrong. Digital APS-C with a 10 mm Hyper-Wide Heliar or scanned 120 film with a 38 mm Biogon — in most (not all) applications, you won't see any significant difference.

Using the SWC definitely is more fun, though ...
