Excellent video, I have a problem with fungus inside my lens, also getting the Error 01 no communication with lens. I cleaned the contacts as advised but no good. I've sent it back to Sigma for repair. It has to be sent back to Belgium, we have no Sigma repair facility in Ireland and Sigma UK won't take them since Brexit. Unfortunately it's out of warranty so will probably be expensive to repair. Keep up the good work.

Cheers, I have the 150-600mm Sport and have unfortunately a small amount of fungus and dust due to the extreme weather conditions. I'm pretty certain they are similar design so may attempt to clean the front lens section.
@CamerasLensesEtc2 жыл бұрын
Many lenses have the same design, so most likely you can remove the front lens element using my cleaning tutorial videos. Inside the lens it is easy to scratch the coating of the lens (they are not like the outer side of the front lens), so I would highly recommend to use a very soft microfiber cloth, and don't push the cloth very hard on the lens element.

Very impressive video. Great production values augment your skills. Any of the procedures improve my rather stiff zoom functionality?
@CamerasLensesEtc11 ай бұрын
Not likely. You would have to disassemble the lens almost completely to check which part is causing the zooming problems.

Thank you for the video. I have one of this lens and need to clean it up. Can you tell what is the cleaning liquid (is it isopropilic alchool)? Will you make another video on how to clean the other glasses of this lens (the middle one and the back ones)? Again thank you very much.
@CamerasLensesEtc2 жыл бұрын
I use isopropyl alcohol for cleaning. The best way to clean the lens is to use the alcohol first, then use distilled water on the lens element then wipe it dry. That worked well for me. In order to clean the other lens elements, you have to disassemble the lens which is very difficult. I don't have video about it.

Hi there. Do you have any information on disassembly and dust cleaning for Sigma APO 170-500mm F5-6.3 AF D telephoto lens? My copy is pretty dusty, and I'd like to clean it. Filter thread is 86mm, and I can't find those glass element rubber removal tools in 86mm size. Can 83mm size work? This dust greatly affects sharpness of the lens, and I don't want to have another paperweight.
@CamerasLensesEtc Жыл бұрын
I think the 83mm would work. I bought the full set, and one of them was the perfect size.

Fantastic video, thank you. I had a really dusty one of these and followed your video to disassemble the front elements, I got the dust out but there's an ever so slight haze on the elements now and no matter what I do, I can get rid of the haze. Any suggestions my friend? Thank you so much in advance.. I used Isopropanol alcohol and also tried screen cleaner.
@CamerasLensesEtc3 жыл бұрын
Make sure that you use a completely clean microfiber cloth. I clean them regularly, and wash my hand before I touch them to avoid any grease / oil contamination. Maybe that was the source of the problem. I would recommend to try to clean of the lens element with a clean cotton bud with alcohol to see if it can remove the haze.

Hi, the screws on my lens are very tight. I’m using a screwdriver with a small grip and it slips. Is it just a case of getting a longer screwdriver with a larger grip or do they need some sort of lubricant? Thanks in advance!

I don't use any lubricant, but make sure that the head of the screwdrivers fits perfectly in the screw, otherwise it damage the head of the screw.

Anyway, if you don't want to buy it, then you can use a thick (drinking)glass which diameter is the same as the ring, and put small striped of double sided adhesive tape on it for grip.
