I got the developer mode to work on my k3 II but its not copying the lens data to the card :(

@@DuneKankel Yeah, same here. I was lucky and got a good deal for K-5. It worked just fine. I don't think this function is supported in cameras newer than the K-5 II.

Yeah, lots have tried but frankly we don't know what settings need to be applied in the conf file. No reason it shouldn't be fixable, but it hasn't been figured out. Id suspect someone with technical documentation could figure it out. Changing the settings manually would take a very long time via Trial and error.

Awesome news!!! I am happy this tutorial is still providing value. Yes, I don’t believe PKTeather ever really worked with the K3. It’s very fortunate you have an older camera body that is still compatible. Enjoy the newly converted lens!!!

I don't believe it works on Mac. So sorry... Good news is windows laptops can be found for almost free at Pawnshops if you don't have a friend who will let you barrow theirs for the day.

mnm ihsan a prime lens would probably serve you better

Justin Hamblin so where is 70 to 200mm f4 use for

You have quite a bit of homework to do. I suggest you rent one to try it out. If it works for you, GREAT. Remember, f4 is not great in low light. For all else, it will mostly work fine for you. It isn't sealed against the weather, it doesn't have IS, it is a f4 lens, it is NOT good in low light. For the money, you would be better served by a 35 to 50mm prime & a 70 to 135mm prime to do your wedding / portrait work. The 70-200 f4 is a budget work horse lens for news photographers mainly.

Justin Hamblin ohhh thank you bro

Way to go!!! Glad to hear that!

I got it thanks you

Wonderful! Glad it worked for you!

Great news!

Thank you for sharing your experience. I am sure it will help someone. I am glad you were successful!

Ole Nørholm check the description, the link is there 😀.

I found the link. But i still don't get the menu so i can moove on. I have the newest software in the camera. Hope yoy can give me helt so my 50-135 will wake up

Ole Nørholm I have only worked with the K-5ii. My understanding is they behave the same as other cameras. Just be patient and follow the process and you should be fine.

I am very sorry. I didn't create the files nor do I know how to. I didn't create the "hack" procedure either, I only organized it into a video from several threads. I was hoping to simplify the process for others. Lucky for you, prices of old Pentax Cameras are low. My suggestion is to purchase/rent a camera that is available for the mod. Just remember, it costs $220 as of today to get an official SDM fix, so if you are buying a camera for this, keep it under the cost of repair and you will be money ahead.

Well, They are probably both good. I would suggest you think more about what you will be shooting and purchase the most used lens. Remember, 70-200 is a long lens, and if you find yourself looking for wide shots from time to time, it won't serve you best.

thanks

thanks

Canon EF 55-200mm f/4.5-5.6 II USM or Canon EF 70-300mm f/4-5.6 IS USM or 70-200 f/4l which is good for canon 80 D ?

Hard to answer you on that one. The 80d is a great camera so any of these lenses will work on it. Don't worry too much about your camera, worry about the field of view and quality of glass. I might steer you towards the 70-200, only because you get a constant f4 which is very nice if you shoot manually or zoom in and out a lot. The constant aperture is nice since it is one less thing to worry about. Now, if you need 300mm, then you don't have a choice. You need the 70-300. Happy hunting!!! BTW, try looking at Flickr for examples of what these lenses can do, that might help you make your decision.

You may want to check your camera firmware version. Make sure you are on the most recent version. Next, reformat your card, and download the files again. I know some people with mac have issues with the files being renamed. make sure that isn't happening.

Vlad Fishermann I think Sonic or Silent drive motor.

Supersonic Drive Motor - ive read it on Wikipedia already ;)

Worked with mine that died this morning. Slow AF but working again. Probably will need to convert to scrdrv af sooner than later but thanks for the hack!

All current file locations worked for me - Jan2017.

Side note - do NOT check off the windows box that says always open LNS files with this app. If you do, it will save in the default format. In the case below, a TXT file. You can still make the save but select ALL FORMATS in the file type and add .lns to the file name and save to the NEW location. I accidentally overwrote my original - simple fix by downloading from lens before proceeding.

Larry Hunt way to go! Glad you got it done! Enjoy your "new" lens!

Glad this worked for you! I understand a lot of people couldn't follow the process as it was previously outlined. I had to put the steps together from different threads, which is why so many had issues. I am happy I was able to help.

I am hearing people have trouble converting with the K-3. Unfortunately, I don't have access to one to test this out and resolve the problem. I would recommend renting the camera or sending it to the user in Pentax Forums who will convert the lens for you.

Glad to hear that! Enjoy the revitalized lens! I love mine.

I had been looking around and wanted to try this but the instructions were kind of iffy until I found your video. Wish Pentax would put option in the menu.

I was in the same boat. I decided to dig for the actual process and fix my lens. I was hoping to give others confidence to do this and save them some time. It isn't terribly hard, but without a step by step it can be scary. I am happy this helped you and I hope it continues to help others.

Cool...was going to take it apart and try unjamming the motor...this was much easier. The noisy screw drive does not bother me.

Hello, the link is in the comments. :)

Eric Barriga Wonderful! I am very happy to hear this worked for you! Happy shooting!

@@BamJham hello，may i asking a questions? ruclips.net/video/dBoisNGBrNo/видео.html Why i can't saving lens rom for SD card .

I don't remember seeing that camera in the hack folder. I would go and take a look at the link to dropbox in the description, perhaps the user who created these files resolved the issue.

Bummer. I don't have a K-3 to work out why PKtether isn't working. I did a quick search of the Pentax Forms, it seems the camera's firmware may be an issue. Perhaps you need to upgrade to get it to work. If you can't, there is a user on the forms who will convert the lens for you at a reasonable price.

Way to go! You are welcome!

You are very welcome! I am happy this helped you!

+Aléxandros Z. Thank you Alexandros! I made this video some time ago and yes... I was a bit picky about lenses and gear. I care much much less about the gear now. All I care about now is the final image and plastic switches have very little to do with that!

Sharpness is based off of several things but primarily focus, aperture, iso, and lens quality. While shutter speeds do affect blur it will not affect sharpness as much as the other settings above. Of you can afford the is version you will be pleased with its results. Btw, I decided to sell this and buy a pentax k-5ii. The camera is weather sealed and has in body image stabilization. Loving every minute of it! I am also using the 55-300wr lens which is weather sealed. At 200mm you still get f4 which is comparable to the canon lens. Great iq as well. NOTE: I realize canon L glass has an advantage, but you get so much more for your money with Pentax.

Justin Hamblin Hi Justin, If i use a Speed Light , does this solve the problem of low light ?

Speed lights will solve this problem. F4 is actually a good aperature for most situations. If the area is a bit too dark after that, then using the speed lights will help. Remember, this lens is very versitile, you can use it for portraits and wild life. I think the lens works great for portrait work. While the focus plane is not as thin as a f2.8 would be, it does pretty well at blowing out the background, especially if you use 135-200mm. Happy Shooting!
