Default Help! I broke it.

My wife and I share lenses between us, its one of the nice things about both of us having Pentax cameras. Anyway, last night I took the 18-55 kit lens off her camera to use on mine and took one of my old lenses off the shelf and put it on hers to protect the body until I replaced it. this morning, my wife asked why her camera wasn't working? When I looked to see what the problem was, I found the lens wasn't registering and it was locked on and won't come off the camera. Its an old Albinar 28mm lens. I've had it on my K-20 several times with no problems but, for some reason its not wanting to co-operate with the K100. Question now is, what can I do to get it off? I don't care if I have to destroy the lens.
Anybody have any ideas? Please.

think this is to do with a spring loaded locking pin that happens to align up with the autofocus motor

make sure the camera is set in autofocus mode that should push the pin out slightly - then if that doesn't work then you'll need to try get something very thin and slide it it between the lens and the camera and hope to get it off that way - failing that sounds like a jo for a haksaw but thats likely to get a load of debris into the mirror box so be careful and make sure the camera is above the lens when you chop it off

Hi GW,

I'm sure that you know about the Ricoh pin thing. . . If this Albinar has this, then it might be the problem -- or something similar. I've never dealt with this personally as I only use Pentax and big Three third party "A" or later K-mount lenses, but I believe that the pin falls into the screw drive opening and prevents the lens from rotating. Does the lens release at all? If it does, then there should be some play between the lens and body. If there is, then you might try sliding a very thin feeler gauge into the space between the lens and body around the circumference of the lens and see if you can coax it around the full circle -- and don't forget to depress the lens release when you get to that area.

That's the only self-help advice I can give. . . Otherwise, I'd just bite the bullet and give it to a trusted camera repair guy.

Good luck!!

Scott

Thanks, John & Scott.
I'll try those tips and see what happens. I don't think this lens had the pin like the Ricoh had, I've used it on my K-20 and K-10 and Samuns GX10 with no problems, so I'm really stumped as to what happened. I'm going to get my feeler gauge... thanks.

Well, I couldn't get the feeler gauge to work, no room to get it in.
So, I took a deep breath... got my shop vac and held the hose with one hand near the blade of my bandsaw
(don't try this at home! the person doing this procedure is a pro.) where the shavings would be sucked up, and held the camera firmly with the other and proceeded to cut the lens. I got about half way through when all of a sudden...
the lens came off!
I gave the body a quick pass with the shop vac just to be sure, then went into the house put the 18-55mm lens on and fired off a couple shots. Works great now and I think my wife will keep me after all.
Here is a few shots of the lens.

In the first shot I can see only one place where I think the lens could possibly lock into but, I don't really think this was the problem.


Here you can see where I was cutting the lens.


Apparently I was cutting something inside pretty close as this curled piece came out out of the lens as I took the lens from the saw.



Anyway, on the bright side, I got the camera working and...
now I have an extra set of lens caps!

LOL! No way, Ronny!
That story goes like this...
(me) I'm sorry dear, I broke your camera so, I'm going to give you my K-20 so you'll have a much better newer camera and you won't have to be without one while you wait for me to find a deal on a replacement. OK?
(her)
Oh, you're such a thoughtful man, I know how much that camera means to you, I love you so much! (hugs & kiss)(me) That's OK, dear, I'm sure I can find a deal on a camera on line sometime after Christmas when prices come down. (then as soon as my income tax return comes, I order the K-5.)

Does the lens still work? Do you want to sell it? That is the first sawed Albinar I've ever seen! Must be very rare!! Probably get a fortune for it on the Bay!
