Help! How do I set shutter speed on my shutter-speed-free Hasselblad 150mm lens?

[ame01999]

I'm new to the Hasselblad system. My 50mm lens makes sense to me: set EV value from light meter, keep it constant, set the aperture, get the shutter speed.

My 150mm Sonnar f2.8 does not have shutter speeds. Even ChatGPT doesn't believe me when I tell it this.

It does have an EV scale. I assumed I would select the EV value, choose the aperture, and the correct shutter speed would be selected, but hidden from me.

But that assumes EV and aperture can be set separately. They're on the same dial! I can't even tell where the correct EV value could be selected.The previous user has put a tiny star sticker that I thought might indicate something, but there is no way to move the protruding segment with the star on it independent of the EV dial. If I move the only dial I can move, aperture changes while. . . well, I don't know what EV is doing because I don't see anything that selects the EV value.

Perplexity says this system of hiding the shutter speed was supposed to be good for beginners, who could dial in an EV, then change the aperture, with the shutter speed adjusting behind the scenes. In theory, that makes sense (except for forcing users to memorize corresponding shutter speeds), but again, I need to specify two settings to the camera: EV and aperture, and I only see a way to select aperture. Can you help me see what I'm missing? I was happy to find an f2.8 150mm at a good price, but I seem to have acquired a foolish exposure system. Thanks for your wisdom.

(I thought pushing the tiny button next to the tiny star sticker would somehow decouple the EV from aperture settings, but pressing the button only bypasses the discrete aperture steps, allowing for a smooth glide between apertures).

The 150/2.8 is for the focal plane shutter Hasselblads and doesn't have an internal leaf shutter. I suppose you have a 500-series body? The 200x-series bodies with focal plane shutter have the speed selector near the lens mount. Those can use both F-lenses and leaf shutter lenses.

Bay77 for Hasselblad F2.8 150mm?

I'm eyeing a long lens here, and was thinking of buying a filter/filter adapter in advance: https://www.ebay.com/itm/235830539090 But my chatbot told me the lens requires a Hasselblad Bay77 size filter. I couldn't find any in existence on eBay. Is my chatbot wrong, or are such filter sizes...

OAPOli is quite right.
The thing about the focal plane 200 series Hasselblads is that the shutter is in the body. This is why without a shutter the lens you have can achieve F 2.8. Lenses with shutters have smaller maximum apertures, but can be used on both 500 series and 200 series versions of Hasselblads. The equivalent 150mm lens would be an F4.
200 series lenses tend to be more expensive, but the cameras are ageing.

Which Hasselblad camera body do you have? If it is the V Series I can answer your questions. If it is the 200 or 2000 series which have a rear shutter and depending on the lens possible as lens shutter. I unfortunately do not have any working knowledge of the 200 or 2000 series. However look up Hasselblad Historical [www.hasselbladhistorical.eu/HW/HWVSys.aspx] to find the manual that you need also Butkus Manuals [butkus.org/chinon/hasselblad.htm] which is free but a $3.00US donation keeps his volunteer work going.

Stop asking bots like ChatGPT and Perplexity for answers to technical questions about equipment.

These are just programs that hoovered up the open internet and then spew out average answers dressed up in grammatically correct English.

For something that is not average, like say the Hasselblad focal-plane shutter system, they are likely to be wrong and will eventually give you instructions that damage something.

In this case, as the other human posters said, they didn't tell you that you have a shutterless lens that probably works fine but not with your camera body. It's just shutterless like most lenses for 35mm SLRs.

The 150/2,8 Sonnar has no built-in shutter. It was designed for the 2000/200 series Hasselblad. You can mount this lens on a 500 series Hasselblad, but then you can only use long-time exposures by using the auxiliary shutter. You need to buy either a 2000/200 series Hasselblad for this lens or a 150/4 Sonnar for your 500 series body. The latter lens has a built-in shutter.

yes, the lens is made for the F type bodies, so you can't use it on a body without focal plane shutters (like the 500 series).

the upshot is that it's worth more then it's copal shutter equivalents, so you can sell it and buy a 150 F4 CF (or C) version, which will work can be found rather cheap.

I do prefer the F2.8 version myself, which is one of the reasons I'm using the F bodies, but the F4 is a very nice lens as well. not the absolute sharpest but great looking for portraits.

that's simply not true. the trick is to use the reasoning models on technical questions. I asked the question to deepseek R1 and gemini thinking and both answered correctly and in great detail why the lens won't work on a 500 body.
