<p>The light leak you see can be explained by a bad fitting spoolholder. It will need to be fixed.</p>

<p>The deterioration of the anti reflective coating is not a problem until it starts to detach, usually as dusty particles. I expect paint will provide a short term solution but if the substrate is failing it won't be a permanent solution. Replacement is the best answer, either getting the panels exchanged with genuine Hasselblad replacement parts or using excellent alternative 'flocking' material from and optical specialist like Edmund Optics.<br> http://www.edmundoptics.co.uk/lab-production/general-tools/light-absorbing-black-out-material/54585/<br> In my opinion this material may be superior but only time will tell. Removing the old material is the hardest and dirtiest part, a hot knife blade is best!</p>

If you are thinking of working on this lens you will be pleased to know that it is much like the other Hasselblad lenses inside, the control rings are different of course. The front glass assembly his detached by unscrewing the ring in the centre of the lens after loosening the grub screw, the rear glass assembly unscrews from the back

Hasselblad Planar 80 mm C T* disassemble.

The rear optical group just unscrews, very easy with the correct tool but without it you would have a great problem holding the right part of the group to avoid causing any damage. -
Zeiss Planar 80mm f2.8 - Blurry Parts
douglas_fairbank replied to oliver_vogler's topic in Medium Format
With some of the all metal lenses it could be as simple as a loose metal retaining ring. With some of the later lenses a broken plastic part could be the problem and that is terminal. Good luck. -
<p>I think you will find that the ring unscrews into 2 parts and plain unthreaded filters will fit in. They sometimes are hard to unscrew and my recommendation is that you use a sheet of rubber or two and try not to 'squeeze' the ring as you grip it, use flat surfaces to get the friction you need.</p>

A12 back firing shutter with dark-slide still in.
douglas_fairbank replied to YosemiteSam's topic in Medium Format
<p>You have not reassembled it correctly, the lever and spring in the bottom of the slide chamber is the problem, you will probably find that the plate is not perfectly flat. Have another go.</p> -
You need to lift and slide.

Hasselblad 553 ELX problem: winding winding winding?
douglas_fairbank replied to donal_kelly's topic in Medium Format
<p>You may have 2 problems here. First fault, spacing is governed by the film magazine, the body, electric or manual, does not influence the film spacing so if you are getting 11 frames with large gaps you have a magazine fault!<br> Second fault is the motor continously driving and could be caused by (a), the drive failing to engage and is a mechanical fault with a gear connected to the lens drive, or, (b), a microswitch fault that fails to switch off the power when the body is cocked.<br> There are great repair guys out there but they may not be experienced with the Hasselblad cameras. Check through previous posts in this group to determine who is highly regarded in whatever part of the world you are in.</p> -
If the camera jams or the lens shutter sticks it is faulty! It will probably need a service (cla), the 'unjamming' is not a fix! If you do get the camera because it is in good condition please budget for a service. There is not a single problem that causes the jam up of a body, the action of the body shutter, mirror and lens drive all have to happen in the right sequence for it to work properly at the right time, this is why a complete clean and relubrication is the only realistic repair. A possible exception would be when a part is broken but if that has happened it will jam every time.

Problem with Hasselblad 500 EL/M triggering
douglas_fairbank replied to kelvin_franke's topic in Medium Format
<p>You can also release the camera from the DIN socket, please see the picture. You could also have a mechanical problem with the solenoid release, a connecting lever may have broken, if this DIN socket test fails in the same way I expect that is what it will be.<br> <img src="https://dl.dropboxusercontent.com/u/5279928/DIN%20socket.jpg" alt="" /></p> -
<p>It could also be a very worn lens bayonet, if this is the only lens that has this problem.</p>

Hasselblad 500 Issues with mirror and crank
douglas_fairbank replied to john_booz's topic in Medium Format
I think the problem you have is that the mirror lever needs adjustment. The movement of the mirror is not quite enough to engage the latch. -
Heliopan B60 orange filter doesn't mount on an 80mm CFE
douglas_fairbank replied to cheng_qing's topic in Medium Format
<p>I think you have a B50 filter.</p> -
Hasselblad 201f shutter/mirror problem
douglas_fairbank replied to patrick_kwong3's topic in Medium Format
<p>OK the battery is good but is it connecting well in the holder, try measuring the voltage at the battery holder connections.</p> -
<p>I think the problem may be that you are trying to advance the film frame by frame with the winder on the film magazine. Starting with a cocked camera you load the film to the number 1 position and then just take pictures winding only the camera. Don't wind the magazine again until you get to the end of the roll and you wind it off.<br> Film back manuals are available here, http://www.butkus.org/chinon/hasselblad/hasselblad_a12_a24/hasselblad_a12_a24.htm<br> The old Hasselblad website used to have all the manuals free to download but I don't think you can from the new website.</p>

<p>Tom Chow is right in my opinion, the baffle is an easy replacement for an experienced technician.</p>
-
<p>The part you require is 1099500410000 and you may be able to order it from Hasselblad, be warned, it is expensive!</p>

Focus issue Hasselblad 500c/m and 80mm planar
douglas_fairbank replied to robin_kuusela's topic in Medium Format
<p>It sounds like the mirror is misaligned, the foam cushions supports may have perished. Check the screen focus by viewing an object at a measured distance and then see what the focus scale of the lens indicates when it is in focus.</p> -
I also have a 500cm with my own name engraved where you would expect the serial number, the factory in Sweden did it for me. Why not post some pictures of your camera so people can offer some help.

<p>You need a Focusing Hood E, stock number 42317 or 42325.</p>
