Lens Stuck On K-10D

[lauren_macintosh]

<p>I got a Sears 135mm and mounted it on My Pentax K10 D and now it will not come Off any thoughts on this matter<br>

thanks</p>

<p>Unfortunately some of these lenses will have a pin that will lock into the K mount where it's not supposed to. It's a bugger to retract. I had this happen to me once and was lucky enough to force the lens off with a little wiggling and not hurt either. For other's the pin needs to be cut to get the lens off.If you have a camera repair shop nearby, you may need to take it there.</p>

<p>How it's done is here: http://moyworld.com/StuckLens/Stuck_Pentax_Lens.html</p>

<p> Yikes, I read the "Stuck Lens" link and I wold be a nervous wreck to try to do something like that with a KD20 and a lens worth more than half the price of the camera body. Also I'm not at all egar to have fine metal particles drifting around inside the camera.<br>

However I have had an accident or two and put the damaged lens in it;s original box and shipped it off to the local authorized camera repair shop about an hour drive from here. A month and a a few dollars later the repaired lens returned, now works as good s ever. <br>

A pro repair shop will repair and clean things up before they give it back to you. Or possibly if it's and easy fix how to make the repair without the need of a hammer or skill saw.<br>

Even if you decide you are a camera sergeon, you could call your local repair guy to see if they have a second opinion.</p>

<p>If the lens is stuck with the notorious Ricoh P pin, there are some approaches to try</p>

<ul>

<li>Try gentle wiggle of the lens in twisting motion</li>

<li>Try toggling AF/MF switch while wiggling the lens in a circular motion. The in and out of the AF connector pin may push back the Ricoh pin back to its position. But you have to do this concurrently with the wiggling of the lens giving the lens a better chance to free from the stuck pin. </li>

<li>Both #1 and #2 above need you to have the lens mount release button pressed fully.</li>

</ul>

<p>I have documented the <a href="http://www.techtheman.com/2009/12/ricoh-pin-and-pentax-kr-mount.html">Ricoh p-pin and Pentax digital</a> bodies in my blog. But if your stuck situation is not related to the Ricoh pin, it is irrelevant to you. If you look over the lens description, try to look if it has wording for R/K or P/K-AR where the R stands for Ricoh K mount.<br /> <br />Cheers!</p>

<p>Hin Man yes its a r lens a KR to be exact , oh F___ here we go again, will see if I can win this fight<br>

or do I end up sending it out to be done:</p>

[hinman]

<p>If I live next door to you, I will do my best to free it for you. Be gentle but positive thinking about freeing it yourself as I have done it quite a number of times myself. I am close to fearless on the R/K or P/K-AR mount, but I sure share your frustration. I also get that 'this can't happen to me' when one of R/K mount get stuck on my K-x. The bullet points that I gave above have worked for me as well as couple of others -- I hope that includes you. Remember the lens mount release, AF/MF toggle and the wiggling of the lens have to happen at the same time. </p>

<p> I will help you with the option that you can send it to me as one of your last resorts. All the best and cheers from me in Bay Area in California: my email contact information is in my blog page as well as Send email in photo.net profile page.</p>

<p><strong>If you get a Ricoh lens jammed on your camera...</strong><br>

If you do get a Ricoh lens stuck on your Pentax camera, you can often remove it by inserting a thin feeler gauge between the lens and mount on the lower right-hand side (with the camera pointing towards you) and working it around until you get it between the flange and the offending protrusion. It can take a long time, but you will usually (usually!) be able to get the lens off.</p>

<p>Hope all is well and I will try my best to help you if you can't get it off. Please do visit Peter's suggestion link as that has a lot of information especially on feeler gauge that may not be thin enough to get into the pin. <br /><br /></p>

<p>I like the information on the first link as the user ends up using a saw blade. But be warned that AF/MF switch has to be on MF position so that the AF connector is in the off and withdrawn position back to its groove; otherwise, you end up destroying the AF connector if you try to cut the pin the brute force approach. If you happen to have a film camera with AF such as the PZ-1 or another earlier digital like the DL/DS/*ist, you can also take a good look for reference.<br /><br /> And really before you do anything drastic, try the simple wiggle suggestion that I mentioned in my two postings in the <a href="../" target="_blank">photo.net</a> thread.<br /> Cheers,</p>

<p>I've got it off with the feeler / gap gauge trick. Do not take a saw to the lens. Go to the auto parts store and look for a gage that has thin sheets that flip out for measuring and setting gaps. Take it home and start trying to wedge the thin sheet between the lens and the pin. Make sure that the AF is disconnected/off and manual focus is selected. I don't have the exact directions, but that pin is on the bottom left. One you get a thick enough gap sheet between the lens and body that is strong enough to force the pin back up into the lens, just twist and it wil pop right off without damaging the camera. </p>

<p>Total to fix your issue: less than 10.00.</p>

<p>Then either search the internet for directions on taking the pin out of the lens (it will still work and is also an easy adjustment that will take less than 5 mins) or throw the lens away. </p>

<p><br />Good luck. </p>

[lauren_macintosh]

<p>I thank you all for your responses on this matter and all the links and other information on this problem<br>

Will proceed with caution will get a feeler gauge and go from there Thanks Again : Lauren</p>

[hinman]

<p>I like Jemal's suggestion with past success in trying out the feeler gauge approach. I try to add few more pictures to help Lauren to understand the position of the stuck pin.</p>

<p>First, this is how the pin looks like. Some of them are retractable but yet they may still jam due to long length and perhaps lost of springy retraction of the pin due to age.<br /> <br /><br /> <a href="http://www.techtheman.com/2009/12/ricoh-pin-and-pentax-kr-mount.html"><img src="http://farm3.static.flickr.com/2514/4173362850_1063a271d7_z.jpg" alt="" /></a><br /> picture links to source</p>

<p>Now, the pin is mostly likely stuck at around the <strong>AF/MF connector pin</strong> that is right <strong>around the 5:00pm</strong> position in this K7 front facing picture that is <strong>close to the two SDM golden pin connectors</strong><br /> <a href="http://www.dpreview.com/news/2009/5/20/pentaxk7dslr"><img src="http://a.img-dpreview.com/news/0905/Pentax/K7_mount.jpg" alt="" width="650" /></a><br /> picture links to sources<br /> <br /> When you <strong>toggle between AF to MF and vice versa</strong>, there is a good chance that you can free it as the the engagement of the AF switch connector may <strong>push the pin back</strong> to its position that is similar to the following picture that I use my thumb to push the Ricoh pin back into its position. Again, all the action need to happen at the same time while you have the <strong>lens mount release fully depressed</strong> and you <strong>wiggle the lens</strong> in a circular motion as you will normally do in dismounting lens.<br /> <br /> <a href="http://www.techtheman.com/2010/03/access-p-mc-70-210mm-f35-macro-in-rk.html"><img src="http://farm3.static.flickr.com/2581/4172606087_e1350c2dee.jpg" alt="" width="500" height="332" /></a><br /> picture links to source</p>

<p>And if you go the route with the <strong>feeler gauge</strong>, make sure the AF/MF is in the <strong>MF position</strong> so that the AF connector is out of the way and your feeler gauge is poking at the Ricoh pin instead of the AF connector.</p>

<p>Be advised That I found a piece of stiff plastic and shaved down one edge to fit between the lens and the camera body , It worked ,No lens on camera any more . And the lens going back to dealer : Lauren</p><div></div>

<p>YAY!</p>

[hinman]

<p>A yay++ from Hin. Thanks to Jemal and everyone on the thread. Can't be any happier for Lauren's K10D.</p>

<p>I'm always happy to see how helpful and responsive our community is here at photo.net. :-)</p>

<p>I sold a Ricoh lens and camera kit to a buyer and while I watched he bayoneted it onto a dslr Pentax. The d--- lens was now stuck on the camera. I told him to keep the lens and if he wanted to go through with the purchase, I'd reduce the price of a film camera and three lens outfit that he wanted. The lenses to be used on his Dslr and a lady friend would get the film camera with normal lens. He called me later and said he used a credit card to disable the "hated" Ricoh pin and took the time to send me the added amount of the discount I had given. So a credit card and a credit to someone's honesty prompted me to write.</p>

[phyliss_crowe]

Glad to hear you were able to get the lens off without damage to it or the camera. I just hope you're not giving up on Sears lenses altogether. They have a Sears Lens Club over at pentaxforums.com with some samples of what those old lenses can do. Stunning results and an excellent bargain for what they produce, IMHO.

 

 

One of my all-time favorites is an Auto Sears 55mm f1.4; resembles a Takumar physically. Never have figured out why, but when I start using it, I can't seem to stop. It just "feels" good, and the results are sweet!

<p>Some of the Ricoh pin carrying lenses have outstanding optics in a value package. And not all pins will jam, I have quite a few that I can attest in <a href="http://www.techtheman.com/2011/11/ricoh-love-with-ricoh-xr-p.html">The Ricoh Love</a> post that I share with the forum before. You can visit <a href="http://www.theatreofnoise.com/2008/05/ricoh-lenses-on-pentax-cameras-ricoh.html">Robin's blog page</a> on the Ricoh Pin removal instructions.<br /> <br />For me, I never remove the pin as I have the <a href="http://www.techtheman.com/2010/03/ricoh-xr-p-and-pentax-k-lenses.html">Ricoh xr-p camera</a> that can make use of the P pin in PA (Program Action) and PD (Program Depth) mode.</p>

[jemal.yarbrough]

<p>Glad to hear of your success Lauren. As for the pin removal, it really is simple to remove. I just pop it out and toss it in a case, so that if I ever want to put the pin back in, I can. No need to pass up a good cheap lens because of it. <br>

Hin Man ... you are absolutely awesome for providing illustrative pictures. </p>

<p>Jemal</p>

[langkata]

<p>You are good people! This is the only thread of many that I found useful. I first located the pin at about the 5:00 position as described above. I had to apply a little pressure to the lens to really see it through the tiny gap between the silver strips of the body and lens. I then took a tape measure and slid the edge right into the gap aiming for the pin. It was surprisingly an easy fit (tried several other materials from around the house with little luck). While holding the tape measure in place, I held the release button on the body and rotated the lens. It came right off.<br>

Thanks for the helpful comments and I hope my brief description of my experience can be of use.</p>
