You're welcome, thanks for the feedback!
Great!!!
Thanks!
Thank you very much for this very interesting video. I had to repair my old 50mm 1.4 USM some days ago as it had that well known (auto)focus problem with a warped barrel. While taking it appart suddenly I had a tiny copper(?) washer lying on my desk with an outer diameter of about 3.6mm and an inner diameter of about 1.9 mm. I have no clue where its proper place is inside the lens. Can you give me a hint?
Hi you're welcome, happy too hear that helped. Regarding the washer, I don't remember to be any of this on it, are you sure it didn't come from something opened previously??
thanks you very much for this video, helps m so much, one question whats the lubricant you use or i have to use to lube inside my lens, regards,
Canon has their own lubes which is impossible to get, specially if you're not affiliated, second thing, lenses is something that I'm not fully experienced. I recommend to reach Learn Camera Repair group on FB, the's plenty of lens repair experts there, try to give it a go there.
Do you know where to buy replacement for the part you remove at 11:35? This screw was too tight and I have worn it down, but my replacement barrel didn’t come with the part
That part is the focus barrel cam, one of the most common issue with this lens, it bends very easily. Unfortunately the internet is overpopulated with copies of this part and there are very bad made. Avoid any Chinese copies of this part and try to get genuine part from trusted sellers. The part number is: YA2-1765
if it was an older classic manual mount lens, would this be one way to change the lens mount permanently instead of attaching an adapter? (obviously AF lenses wouldn't work but would the former be possible? since it looks like the mount ring is removable?
There are no mounts made specifically for vintage lenses to fit on modern cameras, would be more expensive. So that's why the adaptors were made. The mount is removable in order to replace in case of damage but also to reach other internal parts.
@@CameraRestore I see. I was asking primarily because I have two adaptors, one is for a Pentax K Mount (PK) SLR lens to a Canon EOS (EF-S) mount and the other is for a Nikon F/AI/AF-S/G Lens mount to Canon EOS (EF/EF-S) Mount whereas the ladder works perfectly fine and keeps the lenses snug to the camera body but the former one is a bit loose* with its locking mechanism when attached to the lens (while the attaching side to the camera body is snug). I was just curious (in theory if I drilled my own holes) if I would be able to remove the current mount of the lens and dismantle the adapter's mount and have it permanently affixed to the lens so as to have, for example, the Pentax lens have a permanent Canon mount. Of course, drilling my own holes and the mount having a diameter that would actually fit in the lens would have made it seem pretty naïve of me to ask this question since it would depend on those factors, but even without being more clear you've seemed to be able to address my question in a way that gave me an answer to what I was really trying to ask. Thanks!
In case you were wondering what I meant or if you might have a different answer in that case, what I had meant when I referred to classic manual mount lens was just referring to an older lens that didn't have the circuit board or electrical contacts in it, not necessarily vintage (unless that is what you mean by vintage then my sincere apologies) such as the Pentax manual lenses, then would it be possible to transplant one mount of a lens to another lens. But, that was before I even realized to take into consideration how the mount plate itself and how it is screwed on with its screw placements and whatnot. But if they were made to be removable in order to be replaced in case of damage, then that's why I thought that perhaps they might sell the mounting plate with its own part number where I could drill my own holes to match that of a Canon lens' mount plate, for example, but since you've mentioned they don't make them and would be more expensive, then I guess I'll just have to stick to my adapter.
*_The adapter is only loose because the small metal piece they have to lock it in place is slightly off on one side leaving like 1 or 1.5 mm of width to slightly twist or rock back and forth the lens (even though it's still locked in place and won't just come undone)_
The thickness of the mount will vary, so there is no way to use the adaptor mount. One other thing that I forgot to mention, the thickness of the mount varies from lens to lens, even from same manufacturer so another reason why adaptors are better. If the adaptor you’ve mentioned not fit well, than I suppose you should look for a better one.
Any lens that was initially made for film cameras to me now are vintage, don’t know it’s the case of your lens tough.
Good but how to disassembly the frontal element lenses?
Why do you need to take it off?
@@CameraRestore full of dust and other contamination
How to disassembly front lens?
In the front of the lens, on the plastic cover, there are two tiny holes (on the edge of the plastic), you can unscrew that cover but it is very hard to open it because it is glued and almost impossible not to damage those holes, also you will need a special key. Why do you want to take that apart off?
@@CameraRestore hello. After open the front plastic cover. Is there any way to open di front elemens to access the fungus inside. The front lens element seems pressed from the factory. Thanks be4
I also wish there is a way to access the front elements without dismantling the entire lens
