Sony 16-50mm Kit Lens Disassembly, Repair & Reassembly. Fix a stuck lens. 

i think i figured it out. the focus flex cable has sharp bend where the tiny connection might be broken.

You can get a replacement flex cable on AliExpress for about €7, if yours is damaged.

@@BartechTV thanks for the reply! I already ordered now waiting.

did u find a fix

The Sony 18-105mm is a nice lens for video, with a very useful focal range and constant f4 aperture.

Sadly Sony doesn't sell parts like glass elements, and I can't find any sellers on AliExpress or Ebay. Maybe you could look out for another SEL11F18 that's being sold as broken, and buy it just to harvest the front element.

Yes you can find a replacement barrel on AliExpress. A set of both barrels costs about €15

That's probably the most difficult part of the whole procedure. The click is just the sound of the metal pins dropping into the gap at the top of the groove on the inner barrel. All I can suggest is making sure that everything is lined up exactly as you see in the video at 7:44, with the metal pins just above the left corner of the triangle indentation on the inner barrel. Then, holding the front of the lens stationary in your left hand. hold the inner barrel in your right hand and rotate the inner barrel towards you. The metal pins will slide along the top of the inner barrel, until they reach the gap, and then they will drop into the groove, with a click sound. Once they drop in, it's just a case of rotating the inner barrel the other way, away from you, while guiding the pins along the groove until everything collapses together. I know how frustrating it is, I spent literally 2 days with my lens in pieces on the first lens I tried to repair, but it gets easier with practice. Just be patient, and persevere.

Thanks for the reply and the advice. You sir are a class act 🤩

@@JustFluke hello, did you get pass into the problem? I cant seem to click it just like in the video.

You mean the power zoom lever on the side of the lens? It shouldn't wobble, it should be quite securely attached. Maybe the little plastic tab that holds it in place has snapped off.

@@BartechTV I mean the tube that holds lens. It extends when you power the camera. It has 0.5mm wobble like in cheap toy

@@BartechTV I don't normally force bend it, but it also rattles when I shake the camera. Thats why I noticed it
