Hasselblad Planar 2,8/80; the shutter cannot be released

D_Quinn · Oct 26, 2023

Hello, I have a question about Planar 2,8/80 I own. The problem is that the shutter cannot be released.
This is probably because the tiny lever (circled in green) that connects to the body to release the shutter is missing.
(I always tried to handle the lens carefully but I might have done something wrong when I changed the lens.)
If I shake the lens I don’t hear any sounds as if this lever is moving around inside the lens.
Is it something that I can repair? I contacted some repairmen in Japan but they all say they cannot repair it as there is no stock of the lever.
I have already contacted a Hasselblad office in Japan but haven't heard from them.

If anyone is familiar with this issue, I’d appreciate it if you could give me some advice.
Thank you.

Yes, that is repairable. The question is finding a Hasselblad repair person in your country to save on shipping costs if possible. I can recommend Hasselblad Repair in Burbank California, but I recommend that you find someone in your country to save money.

D_Quinn · Oct 26, 2023

Thanks for the response. I hope the repair costs won't break the bank.

The lever lock and unlocks the key, so it's disappearance is probably the cause.

It may just be bent in, and needs to re re-aligned, I've had to tweak a few of these to get the lens and body to sync properly. If the key is locked, then that part of the lever is still there. If you need a new part, then it would have to be scavenged off another lens, which is probably worth while as that is a rather current lens.

You can repair this yourself with an inexpensive tool called the 'Hasselblad tool'; search for it on Amazon. It's an easy repair...; I've done a few myself. Judging from the picture,your issue is not with the lenses but with the body you're trying this lens on. But, the same tool will work for the lens and body; good luck!

I just pulled off my Planar 80mm from Hasselblad body, there's a "pin" in the center of what you have circled in green. I don't see the pin on your lens. Maybe someone else here can speak to the cause.

D_Quinn · Oct 26, 2023

Thank you. Yes, this "pin" is what I referred to as a lever in my original post. Indeed this is missing and causing the issue. This is the closer look of the hole. Any idea?

Steven Lee · Oct 26, 2023

@D_Quinn sorry but I am not understanding your question. What idea? Your lens is broken and needs to be sent for repair. Are you asking about a repair shop? I would suggest Hasselblad USA in California.

D_Quinn · Oct 26, 2023

Sorry for the confusion. Actually, some of the people made suggestions to repair it myself. So my question was if anyone could give me their insight of how to repair myself.

If I don't hear from Hasselblad Japan for a day or two and concluded this is not something that I could do myself then I would start thinking about having it repaired in the US.

Steven Lee · Oct 26, 2023

Ah, I see. If you want to try doing it yourself, here's the service manual. Also, if you want to find a repair shop in Japan, I can highly recommend Kanto Camera. They haven't serviced my Hasselblads, but they did an amazing job on my Rolleiflex 3.5F.

D_Quinn · Oct 27, 2023

Thanks for the manual and the shop info. Actually i have contacted Kanto Camera but they said they cannot repair it unfortunately.

What you mentioned sounds like what's really happening with my lens. When you tweaked it, I assume you opened the covering plate (from the rear of the lens?). Was it really difficult to open the plate? I have never done this and I would need to buy some tools to be able to work on this.

>If the key is locked, then that part of the lever is still there.
Could you clarify this, please? What is "the key" you are referring to?
Thank you very much!!

Not in this case. A part is missing. Please see post #2.

I guess, I doubted that a part was actually missing and we just have a case of a light body jam. Sorry if I jumped to the wrong conclusion.

No problem at all. Thanks for the comment. I really appreciate it.

I believe that removing the 8 screws at the bottom will release the cover and allow you to inspect the pin. Be careful to note the position because the plate holds the helicoid keys.

I haven't done it myself but there are a few videos online.

Thanks for the advice! I found some video of releasing the rear cover but my lens doesn’t have any screws on the back. Actually, I don’t really see any screws anywhere on my lens. Here are the pics of the lens (rear shot and an entire lens taken slightly farther)

Technically, Hasselblad calls the mating piece in the body the "Key", and they call the part on the lens (marked "key" above) the "Cam". The Cam controls charging the shutter spring, opening and closing the aperture and shutter, and releasing the shutter for exposure. The pin visible is the end of a lever that locks the Cam (prevents it from rotating) when the lens is removed. When mounted, another pin on the body moves the lock pin so the Cam is allowed to rotate.

Here's what the rear plate looks like after you remove the 8 screws.

And a look at the inner locking mechanism.

Yours may look a little different, as this is from a "C" lens, and yours is a more current model.

If your Cam is lock and not rotating, then the locking part of that lever is still there, so maybe it can be repaired without a replacement part.

I'll warn you that the part that the rotating shaft mates to in the lens is spring loaded, so it'll unwind when you remove the rear plate. You'll need to re-install the shaft correctly and wind it the correct amount, it can be re-installed 180 out of phase, which would make the lens not work (and probably jam the lens on the body!).

WARNING:
If you are uncertain about loosing tiny screws or breaking precision parts, get someone that is familiar with repairing mechanical leaf shutter lenses to do this - these items are out of production with no spare parts.
You Have Been Warned

Pulling off the rear mount plate is pretty easy for someone familiar with precision parts. If the lock lever is broken, Hasselblad would replace the entire rear plate, as the mechanism is riveted to it. Since you have a very current lens, not as many were made, and therefore not as many parts available. Hasselblad Sweden may still have some.

___________________________________________________________

Edit: Looks like you posted just before me! Is that an FE lens? You will have to contend with the wiring harness as well, and I've not worked on that version of lens, but I think the rear bayonet mount is attached by radial screws (around the side of the lens. Be warned that the lens guide bars are part of this mount, so pulling it off may un-sync with the focusing helical, so be careful!

"9" marks the mount screws on this diagram. I suggest popping off the plastic light tunnel (12) to expose the mechanism and see if something is bent or broken, or missing.

Oh, This is so great! I very much appreciate it! I'll take a closer look and see if this is something that I can do. The lens (shutter) is not working anyway and it seems no one available to repair it in Japan at the moment. I might as well give it a try.

A later model with electronic contacts than is shown in the videos. Leave the lens for a Hasselblad repair person to work on.

Consider selling the lens as-is, and simply buying another - money-wise, it could wind up costing about the same as a lens repair.

Have not worked on such a new Hassy lens, but newer Hasselblads in general incorporate more plastics, and these materials don't always age as well as we might hope. Do you actually need those electrical contacts? On older lenses, that lever is steel, but if it got replaced with some sort of composite substance in newer lenses, it could make life "interesting".

itsdoable · Oct 29, 2023

That looks like a CFE lens, which were not made in large quantities. I've only worked on the F/FE lenses with electronic, and the contacts and cable are fine, but if you remove the aperture ring, the brushes used to electronically sense the selected aperture is really easy to damage, I don't think I've ever been able to disassemble one without damaging those to some extent.

The only plastic part I've had issues with is the outer focus ring on the CF lenses, they tend to brittle with age and crack.

The lens cam lock and pin will be steel.

PS: here is what the back of a CFE lens should look like:

D_Quinn · Oct 30, 2023

Hi everyone for the comments. As 4season mentioned, I better consider selling the lens as-is. It looks too complicated for me. But it's a shame the lens itself is in a really good condition except for the pin.
