Dust on lens elements In Yashica MAT 124 G

In this Yashica MAT 124 G, I will show how to cleaning
lens elements, because there was some haze on the inner
lens surface. It's not that hard to do just be aware and only
lighter fluid, or Isopropylalcohol 90-99% to cleaning the
lens surfaces.

That rear element haze, from old oils is common in these cameras, regardless of the temperatures with which they are stored. Nice video, I wish I had this years ago.

[@dickviddicus]

These videos are wonderful. Thank you so much!

Hi Dear, Will you share the video of the Yasha 124g shutter speed service?

[@kevinflynn6306]

Thank you Mikeno do you think you could do a self timer jammed on a Yashica 124G repair seeing as there are so many problems regards Kevin

[@DirectorRobertProulx]

Hi Mikeno. Could you please make a video on declicking the aperture ring of Canon Fd 50mm 1.8 (new). I understand there is more to it than just removing the roller. Removing some sort of spring or something like that.

[@sanguyer6683]

Great video, I'm looking at having to do this on a recently acquired 124G. I have a question though... wouldn't it be possible to clean the internal elements of the front lens group by just removing the rear lens group and then cleaning the rear of the front group while still mounted by just holding the shutter open while set to B (maybe with a locking shutter cable release)?

[@LarryManiccia]

Actually it's easier to do the opposite. I remove the front lens group using a rubber ring like he used in this video. I clean the front and back of the front element. Then I put the camera in bulb mode with aperture wide open at 3.5. Then just press and hold the shutter to access the front of the rear element to clean it. When done just release the shutter button and screw in the front element. The back side of the rear element can be cleaned from the inside of the camera. This method avoids having to take the front leather off and having to take the front panel of the camera off. Also, you don't have to remove the rear lens element either. I just used regular lens cleaning solution and this did a great job cleaning the haze off the rear element.

What did you see to make you think "somebody else has been in here" at 20:40?

[@mikeno62]

Well, if there is marks from a wrong screwdriver that will slip the screw head, but also from broken painting marks inside the camera.

[@kkjjjssss]

Is it possible to disassemble the rear lens at about 22 minutes into the video?

[@LarryManiccia]

My understanding is the rear element is cemented together and is not meant to be taken apart based on reading info online. If you have dust or other film between the rear elements you're not going to be able to access it.
