ben_georgiades Posted March 27, 2002 Share Posted March 27, 2002 Does anybody know a good way of preventing the accidental release of a lens because it has happened to me twice now.When out and about I use one of those neoprene straps, very convenient. But the release button is quite exposed and the lens is facing down!! There is no lock on the button. Does anybody know a good way to secure the button or prevent its accidetal release.

carl smith Posted March 27, 2002 Share Posted March 27, 2002 Just curious, but how much does this lens weigh? and are you holding the lens, or just hanging the whole thing by the strap on the camera? Link to comment Share on other sites More sharing options...
ben_georgiades Posted March 27, 2002 Author Share Posted March 27, 2002 The Lens is the 80mm standard lens. Hardly heavy. But yes the strap is holding the whole camera & lens. Link to comment Share on other sites More sharing options...
peter_rosenthal Posted March 27, 2002 Share Posted March 27, 2002 If it doesn't interfere with your shooting style too much I'd recommend not winding until you're ready to shoot. I'm told it's more difficult to quit this habit than smoking but it WILL solve your problem. There is no other way to keep the camera from firing. It WANTS to shoot if it's wound!!

ben_georgiades Posted March 27, 2002 Author Share Posted March 27, 2002 Lens release not shutter release. Unless being uncocked makes it more difficult to release the lens? Haven't checked this,don't really want to either, jams and all. Link to comment Share on other sites More sharing options...
peter_rosenthal Posted March 27, 2002 Share Posted March 27, 2002 I lied... there is another way to keep it from firing. Put on a back and put in the darkslide. Peter PR Camera Repair Link to comment Share on other sites More sharing options...
peter_rosenthal Posted March 27, 2002 Share Posted March 27, 2002 I must be missing something here... If your lens is off the camera and fires for any reason, I'd take the rear lens cap and put in on the lens and there is no way to get to the release lever. Prob'm solved.

ben_georgiades Posted March 27, 2002 Author Share Posted March 27, 2002 Ok there seems to be some confusion here. The problem is that the lens can fall off of the camera because the lens release button accidentally gets pressed. I am trying to find a way of securing the button or the lens so that it doesn't fall off of the camera. Link to comment Share on other sites More sharing options...
ernie_gec Posted March 27, 2002 Share Posted March 27, 2002 Ben: If you're talking about Hasselblad here, and I guess you are, I can't imagine the lens release button on the body being a problem in accidentally releasing lenses. These things require a pretty firm push in to allow rotation and release of the lens... this is weird. Link to comment Share on other sites More sharing options...
jerry_lehrer Posted March 27, 2002 Share Posted March 27, 2002 Ben Ernie has given the only cogent explanation of why it should NOT happen. When you say "release", we assume you mean that the lens on a Hasselblad will drop off the camera when the button is pushed accidently. NO, all my H'blad lenses require a firm "bayoneting" action to release it. And I also use a neoprene wide neck strap. Some readers might have assumed you mean that the shutter will release, resulting with a picture of your shoes and the ground. Jerry Link to comment Share on other sites More sharing options...
ben_georgiades Posted March 27, 2002 Author Share Posted March 27, 2002 Jerry, Yeah I think we have cleared up the confusion now. I think what happens is. If the release button gets pushed by accident, by your belt for example. The rotational force required to re-lock the lens in place is too great to happen naturally. Consequently the lens hangs in limbo until one of two things happen, its rotates the rest of the way and falls off, or you notice and relock it. My question still stands is there any way to lock out the action of the lens release button. Or is the spring on mine particulaly soft.

richard_cochran Posted March 27, 2002 Share Posted March 27, 2002 Something which has been hinted at by some, but apparently missed by others is that on a Hasselblad, the lens won't release (at least, not easily) if the shutter isn't cocked. Hence the advice to avoid winding the camera until you're ready to shoot. While this ought to work, I'm not sure I like the suggestion, because if you DO try and intentionally remove a lens while the camera isn't wound, and you force things, I think you may be inviting a jammed camera. Hence, many Hassy users get into the habit of always winding immediately after shooting. Returning the mirror is another reason to wind right away.

barry schmetter Posted March 27, 2002 Share Posted March 27, 2002 Ben, I think you need to get your 500 serviced. The lens release should require a significant amount of pressure to release the lens, and the lens should require quite a bit of torque to turn and remove. It sounds like you need a release spring (?) and possibly some adjustment of the lens mount. Why not send your camera in to Peter for repair. The folks on the Hasselblad list are very pleased with his work. Link to comment Share on other sites More sharing options...
roger_michel Posted March 27, 2002 Share Posted March 27, 2002 ben, i'm sure it's not th answer you want to hear, but your camera needs to be serviced. i have used 500 series bodies for more than thirty years -- carried them many places in every conceivable way -- and i have never had an accidental release. i also have never HEARD of this happening to anyone else. if it has happened to you more than once (indeed, even if it has happened only once), there is no question that there is a defect.

ben_georgiades Posted March 28, 2002 Author Share Posted March 28, 2002 Yeah that definitley was not the answer I wanted to here but, if thats what I need to do I will. Thank you all for your advice. I am heartened to here the description of the amount of pressure required to release the lens. I will have the body serviced ASAP. I also would not want to leave the camera unwound while walking around for all the reasons outlined, plus the mirror is more secure in the wound on state.

Robin Smith Posted March 28, 2002 Share Posted March 28, 2002 Yes, it happens to me and it is irritating. The only way I know to avoid it is to put in the darkslide. Robin Smith Link to comment Share on other sites More sharing options...
jerry_lehrer Posted March 28, 2002 Share Posted March 28, 2002 Robin No, again! The lens can be removed with the dark-slide in or out. There is no interlink 'tween the lens release button and the film back or dark-slide. Just don't try to remove the lens with the shutter uncocked.

Robin Smith Posted March 29, 2002 Share Posted March 29, 2002 Oops sorry, I misread the question -- I thought Ben was referring to the SHUTTER release. I have never had Ben's problem. In mine pushing the button does nothing anyway, you have to push AND twist, so I suspect Roger may be right - you need someone to look at the camera and lens.
