Ricoh Rikenon 50mm : Disassembly and Cleaning

Hello Friends, Today I show you how to open and give basic indications on how to proceed to disassemble and service a Ricoh rikenon 50mm f/2. This lens is for pentax mount, but I guess it exists also on mounts such as canon, nikon, minolta, konica, etc. It can be found cheap a bit everywhere and in my opinion it is a lens that is worth having as it produces good image quality and it's made to last forever when serviced properly. keywords: clean lens fungus, fungus cleaning, fungus removal, lens repair, pentax, rikenon, 50mm, 50, 50 mm, 50 , 50 f2, 50 f/2, lens haze, haze in lens, hazy lens, Can haze be removed from lens?, What does haze look like?, How can you tell if a lens is haze?, How do you fix a cloudy camera lens?, Are haze lenses bad?, How do you get rid of lens fungus without opening it?, What is haze caused by?, What is difference between haze and fog?, How can you tell if there is dust in your lens?, Is it worth buying a lens with fungus?, What is Schneideritis?, How can you tell if a lens is scratched?, How do you prevent lens haze?, Why do my photos look hazy?, Why is back camera blurry?, How do you remove haze from glass?, How do you kill lens fungus?, fog in lens, foggy lens Some useful stuff (I’ll get a small commission if you order thru any of the links): Optical cleaning paper: https://amzn.to/2HXBgYI Optical cleaning fluid: https://amzn.to/323HFci Rubber tools: https://amzn.to/3mEcdco Lens spanner: https://amzn.to/35VCYSL Screwdriver set (includes J-tips): https://amzn.to/3LTPi9G JIS screwdrivers: https://amzn.to/3mC06MQ Scredriver set : https://amzn.to/3JHxPAY (This set has J000, J00, J0, J1) DONATION: https://paypal.me/DiyExtravaganza1?lo...
