I got two of them. One is an earlier bulkier one and the other one is the later slimmer cased one. Fantastic image rendering. However I'd wished to see a demo on how to clean and regrease the focus helicoid. That's what my early 50mm and my 40mm 1,8 is suffering from. Great video. Thanks
I have a very fungussy 200mm f4 hexanon lens that I'm going to attempt to take apart and clean... I would be very interested to see you try this one! Thanks for your video!
Well, this puts me in a difficult position. You see I have that same lens but mine is in good condition(ie no dust or fungus). So on one hand I could make that video, but in the process I could end up making it worse. I'm not sure I made this point in the video, but for anyone who hasn't tried to take apart a lens before, you have to realize that your work space is probably full of dust. As soon as you open that lens you're letting all that airborne dust and debris in! What the video doesn't show is me opening the 50mm lens up like five times before I finally got enough dust and whatever else out of it so as not to be noticeable in photos.
@@dopeyrobot ahhh... I’m in the UK, I assume you live in North America? Otherwise I’d suggest sending you mine to play with! There is so much fungus in my lens that a little dust would be preferable. I only paid about £17 for mine, so I might buy some cheapish tools and give it a go myself. I’ll document it if I can! One question, do you think I need to undo the three sets of flathead screws along the lens? It looks like they line up with where each lens is?
So I have a 50mm 1.7 without notches in the front. Guess I buy me some rubber cups. Just for fixing some greasy aperture blades... Btw, there are lens diagrams on buhla.de Thx for the video!
Hi. What about adding screwdrivers to your initial list? In some cases JIS required...Maybe not needed if you just want to clean the glass, but restoration would include regreasing the helicoid.
Hi! Great video! I found this lens at my grandmother's house and I would like to use it in my new Fuji X-S10. It seems to be ok regarding mould and dust. Should I still do the cleaning? There could be some damages for my camera If I use lens with mould? Thanks!
Hi and thank you for watching! regarding your query I think that the old saying "if it ain't broke, don't fix it" applies here very well. I have a collection of old lenses that I use regularly and have only had to clean two of them so far. The ones that are clean inside don't need to be taken apart. I mainly use a proper lens cloth and wipe the outside glass surfaces as needed.
