I want to buy really sigma 24 70 for sony moun lens but this hall think with dust make me think it twice!cause ive see that sigma for sony came dusty fast also. Anyway,if you always have filter on lens ,and you have them always on camera ,one lens not change, dust will be inside again so fast????
I don't have video about it. If the manual focus is moving freely, and the autofocus motor is not moving the focusing lens elements, then you might clean or polish the motor (the teeth and the metal ring where the teeth sliding), if that doesn't help, then you have to replace the motor.
Thanks for your video on this lens! Do you have any idea where one might get a replacement for the front plastic part that carries the filter thread and lens hood?
I checked ebay and marktplaats, but I haven't found any. Other option would be wait until a broken, same lens is for sale on ebay for cheap, buy it, replace the ring and resell it for repair parts.
Hi thanks for the videos very helpful. is there any way to remove the front element without using lens opening tools ? I can't find one in my country and i have to clean my lens ASAP please hope you'll answer my question
i tried to open a sigma lens which is the 16mm 1.4 for sony apsc. but after removiing the first part, it seems that there is no way to remove the front glass, there is no screws in front ,

Dust comes in the lens between the front lens tube and the other tube which that goes into.
Bonjour vous auriez une vidéo pour réparer l'autofocus de ce modèle ? merci pour votre réponse

Use a thick (drinking)glass with the same size of the front lens cover, and put double sided adhesive tape on the side for grip.
@@CamerasLensesEtc thank you I'll try this method
have a nice day
@@CamerasLensesEtc thanks you it works for me you saved my life ❤️
Good video. Can I clean Sigma 24 -105 also the same ?
I don't know, I haven't done cleaning on the Sigma 24-105 before.
What size screwdriver do you use to remove the screw?
As I have mentioned in the "tools" section of the video, I used a PH000 screwdriver.
it is possible to clean the fongus in between the front element glass?
Generally, no. It is almost impossible the remove the two lens elements then glue them together properly.

Can't you remove it with a lens opening tool? ( =unscrewing the front lens part)
