Thanks helped me fix my Olympus Zuiko 12-60mm, no shop would touch it, and there was some fungus behind the lens.

Obrigado pelo vídeo, me ajudou a tomar coragem e abrir a lente selada da minha câmera que é uma panasonic HC v-100. Consegui abrir e limpar os fungos. Ótimas dicas.

Congratulations on the video. This was the only one I found talking about it. Is the 85mm canon lens glued in the same way? To remove the lens will you need to peel it off and glue it on? Is the glue used silicone?

Thanks for these videos both informative and interesting. I don't suppose you know how to calibrate the focus on the Nikkor manual Internal focus(IF) lenses? I recently bought the manual nikkor 300mm f4.5 ED-IF but I can only assume it had been taken apart then put back together wrong. Infinity is off by about 1/4 of the throw and I can't get close to the minimum focus distance.
I've adjusted some other lenses and helicoids before, but I just can't seem to get to it even after taking the lens groups out.

I need a tutorial for Samsung NX 50-200mm lens. No idea how to remove the sealed element

[ambrosioflavio]

do i need to worry about the rotational alignment with the back lens when putting it back?

Hello friends..it is the only way to clean the modular lenses..and be very careful not to scratch the optic..do it many times.

Hi I have a Sony Camera a6100 and it came with a 16-50 f/3.5 5.5 oss lens and I unscrewed the top piece while testing it and dropped the lens block with the lens piece inside and it cracked what is the little glass piece called inside. I keep looking up the model to replace the little glass piece and it won't appear it just shows me the lens itself.

What if the lens group is made of aluminium? I put it on the hot plate and heated up to around 150c, the glass elements rotate, but stll unable to take them out... Any tips?

Thanks for that ! I have an Olympus 50mm/1.8 Auto-S with the front block that has some fungus. Not so well sealed, huh ?

Amigo te agradezco de sobremanera todos tus videos sigue así, disculpa podrías apoyarme con el como "microajustar" el enfoque de los lentes, una ves lleve a servicio una Sony y me la dieron y tenía el enfoque mal, yo recuerdo que solo quitaron el lente y le movieron algo y al instante quedó...por eso pregunto si ese ajuste sabrás hacerlo ya que de nuevo tengo ese problema con una canon, gracias por tu atención

What can i use if i dont have a suction cup like that?
