Enjoyed your video. FYI - the small "scoop" on the back of the lens is what physically makes this an "S" lens, that is an AiS lens. The "S" stands for "shutter." It allows for Shutter Priority on bodies made in the 1980's and upwards.
Very intelligent repair. One needs to prepare properly to do this. Raised edges on the work area to keep screws from falling and disappearing into another dimension. Knowing the right size driver... Here's a funny thought. I wonder if radioactive lenses have less trouble with fungus. I tend to doubt it...
The bellows version has a different optical recipe thus I assume it won't open the same, but yes, just blowing works most of the time. By the way, the 105P bellow is a wonderful lens. Cheers.
@@diyextravaganza I'm no expert. But I just started learning about these cameras. I understanding is that when automatic shooting became a thing some companies focused on aperture priority and other companies focused on shutter priority. Nikon started with aperture priority, those little metal ears and later the indexed aperture rings. But, at some point, Nikon needed to add shutter priority to be competitive. They invested in a mechanical solution that uses an armature which reaches into the lens and physically moves the aperture ring. That's what the little slot is for. I think within a couple years of this everyone switched to electronically controlled automatic shooting and they had to revise their system once again.
You are removing fungus from the lens by rubbing it with your dirty finger, that contains some dust or other fungus an the skin, also you clean the lens without removing it from its tube, and rotating very sensitive glass against its "holders", also you are not cleaning other metal parts that touches the glass that also contains same fungus.. So it will stay fungus free not more than 3-5 years if average humidity will stay above 40-50% thanks for a useful disassemble video 11likes, but 10 dislikes for your cleaning methods.

Wow, very interesting. You are doing a fantastic job!
Hi, thanks a lot, just trying to keep these beautiful lenses away from garbage, it's good for us and the planet. Don't forget to share with friends.
Wow!! Amazing, You know your Lense work...I am very impressed. Thanks for sharing.
Hi thanks, I started fiddling with lenses somewhere around 2017, for fun !, since, I've worked on maybe 400 different lenses.

Thanks a lot for the explanation, clear and to the point. Cheers.
Great video!just as a reminder..it would be great to see a fungus removal from the middle glass of the 28-105!
Thanks

This is something I have also asked myself. I have a Nikkor-N 35 1.4 that has maybe 50 years, and not a single trace of fungus. Cheers.
minha lente não dá acesso aos parafusos como mostra, pode me ajudar ?
Is it the same model? A 105mm f2.5 ais?
Is have a speck of dust inside rear of the P-105/f4 bellows version. Is similar to open of only blow dust out?

you didn't ask but the slot on the mount is for shutter priority.
Thanks for the info. How does that work? I'm really curious. Cheers.

good advice, thank you !
UV-C light (180-280 nm) will take care of that..
