Many thanks Kaleem.

Thank you

Great to see this Kalim 👍

Sir thank you so much for making this video..I think this is the only video in KZfaq for cleaning the front element of Nikon 200-500 . Love from Odisha 🙏

janab kalim bhaijan aap bahut hi umda video banate ho

Great video. The gaps in the lens are there to let the air pressure inside the lens equalise with the atmosphere during zooming. That's why very expensive lenses don't incresae in length during zooming, they are far better sealed.

The two first rings you removed were broken at my lens. I bought new ones but didn’t know how to apply them. I just glued them. After i d seen your video i finally remover them and replaced them by the new ones. Thank you.

Sir Thank you so much. It's a blessing to see all those. Great Video. God bless you Sir.

Awesome video. Amazing.

thanks for the video 👍👍👍👍

Thank you for the video

If anyone is having troubles removing the first rubber ring, it can be removed with a 105-112mm lens filter wrench quite easily.

Good bro...

Amazing information thanks for sharing

excellent! Thank you.

Good work

Thanks for sharing

Great video! I would love one for the 80-400 4.5-5.6 ED VR if you ever end up doing it! Mine is filthy.

I need the front plastic part on which the hood gets clamped. Can you please guide

Good job sir je

Hello, Thank you for your video. How so you disassemble the first group of lenses ? I have dust inside the first group.

Sir the rubber part is not getting off I am trying hard . Please give some solution

Thanks for the video, very useful :) Where did you get your vacuum cleaner? Do you know the brand? Have a good day!

i have some fungus growing on that frontal element. Can I use this method to clean it?

Thanks Kalim - an incredibly useful video! I recently dropped my 200-500mm. Fortunately the glass elements were fine but the plastic cylinder (second one you removed) that has the hood mount "track" was damaged as well as the hood itself being broken. With this video it seems like the part would be fairly easy to replace.... if only I could get one. Any ideas? (Nikon eat is $450!!)

Sir front main lense is two part how to remove the lenses

Thank you for showing me how the lens is made. I can't seem to remove the end by unscrewing it like you did. I'll try again. Any suggestions on how to loosen it without hurting it? I'm going to tape it where you showed me.

The first ring won’t come off of my lens. Is there any way to remove it with a tool. It just won’t budge.

Hello sir today on field accidently my nikkor 200-500 lens was damaged at front element where the lens hood mount little bend on joint of front element, after this damege i took some images all images are good and fine please suggest me what to do & how much cost goes for replace that element.

I also can’t get the rubber part to screw off. Anybody figure it out?

Hi Kalim bhai, thanks for the video. I seem to have fungus sandwiched between the front element. Something inside glass.. have you seen such a thing ??

what about cleaning the rest of it internally, is it possible ?

Couldn't a small bead of silicone be used in place of tape?

Thank you
