Stiff focus ring In HELIOS 40 1.5 / 85

Тәжірибелік нұсқаулар және стиль

The focus ring was stiff in this old HELIOS 40 1.5 / 85, but it's not so hard to fix, just be aware of remember to set small marks BEFORE you disassemble anything in the focus system, and also do some measurement, it will say, with the focus at infinity, how long is there from the front of the inner helicoid to the back of the focus housing, NOT the mount. Also remember to count how many turn (s) before the helicoid gets off the thread.
In this case I use the LM47 MoS2 grease and it looks like it works fine.

    Pleasure to watch, I went through these steps a while back on a pair of lenses 40 & 40-2 , one of them was really excessively bad. I was using methods and principals detailed in your other videos , to the point I had your voice in my head while working, using isopropyl as penetration fluid on stuck parts is really helpful as are building gloves, the hardest part I found on one was separating the front elements , front lens had fungus on back and the filter ring was bent, after slowly getting the ring as good as I could with a thread stretching tool , (it takes a filter or hood now)to remove the name ring the lens wrench needed to be in a vice, and the big gloves came out, wrench got a little bent, all got cleaned and put together, Thank you for the videos , they are a great help for fixing specific lenses, and give the knowledge for servicing most lenses lens, example pancolar 1.8 50 with a jammed focus.

    I always enjoy watching your videos, Very informative.. Any suggestions or tips on keeping dust out when cleaning elements and final assembly? Perhaps you'd do a video in the future on the subject.. keep up the good work.. And do keep your eyes open for any RE auto topcor lenses.. I know you would really appreciate the engineering that goes into them..( Even the aperture ring runs in a ball race with 1mm ball bearings !!!). : )

    I have a lens that moves a little back and forth. After opening up it looks like I’m missing a couple of those super tiny screws on that black ring you measured 1.3 x 1.68mm Does anybody know where to get them? The lens works but I have to make sure I pull out the lens to get it to focus properly but a couple of those screws I think would solve this problem. Any help would be greatly appreciated!

    Thank you for the references where to buy equipment . I have sometimes used other greases , but they were very smelly . Is the liqui-molly also smelly or not ? Is it toxic to touch ?

    Amazing video! Just one quick question, what did you clean the old grease with? In the video you left, came back and it was all clean 🥲 lol. If you could please give me an advice on that, i would really appreciate it! Thanks in advance! Love your videos!
