Sir, you are an absolute hero for recording and sharing this.

Have you tried soaking the lens in a 50/50 solution of 3% hydrogen peroxide (what you get at a pharmacy) and household ammonia? It chemically removes the fungus, no rubbing needed so you don’t risk scratching the soft coatings.

I love the temporary magnet trick! Worst part is, I knew it in my student days of old!

Thanks for that video! Would be great, if you could do another one, showing how to de-click that lens.

It is good practice to not clean any lens in a circular motion as if anything should accidentally cause scratches they will be longer and more prominent. I recommend going across instead.

Very nicely filmed. I have the same lense and the same adapter. The problem i have is that if i like rotate the aperture or the sharpness ring, the silver circle also moves and like demounts my lense.

Really good Video. Detailled and with nice comparison. I like it a lot. Thank you for that.

Great video, thanks so much for making this.

Sound proof panels on your windows and do a canon Ae-1 program body!!

Doesn't the suction cup leave a mark on the lens at all?

Thanks for this video it’s very well done...any idea how to deal with the aperture ring being stuck at A setting and won’t turn? I cannot mount the lens now for this reason. One time put the lens on the A setting while it’s not mounted and this happened.... I cannot do anything at all to get the aperture ring off the A now...no matter how hard I press on the spring button next to the A...thanks for any tip you may have ....

How to remove the front ring of the 35/f2 and 100/f2 lenses? Should I use a rubber tool as well or pry it with toothpick or..?

Hey man, thanks for this video. Are all the focal lengths built the same?

My front ring seems to be stuck (I have the same rubber tools to remove) any tips on getting it loose?

ugh. to be honest I wish you were a lot more clear on the reassembly of the breech lock. Lenses and elements were straight forward but then when I saw you didnt fully de-click your aperture I realized maybe he isn't totally sure. So currently im stuck with a lens I can't use. I can't figure it out.

Why buy a pro-mist filter when you have a dirty FD lens haha

Is the fd 35mm concave version with chrome nose the same dismantling process ?

What are the room dust conditions? Is there some specific way you drain the particles out of the room? Thanks

Hi, how can I test the aperture if I don't have a canon FD mount camera or adapter?

My FD 50mm f1.4 looks completely different on the inside from the back. The brass section unscrews instead of lifting away and the mechanism triggering the aperture blades is completely different. I've not been able to successfully put it back together so far.

Is this version radioactive?

Is the disassembly process at all similar for the 35mm f2?

Thanks a lot

Привет. Подскажи какую используешь жидкость для очистки линз?

Where can I buy these tools?

Very helpful, thanxxxx!!! Wich tissues u are using for cleaning the lenses? Link?? Greetz, Saartekk

Hi thanks ! after re-assembly aperture is stuck at wide open f/1.4 (it worked before), what did I do wrong?

When you say the fugus damaged the lens. Can you be a little more specific

You don't need all of these tools
