12:29 - That sleeve goes brittle and lose after a few years, and when it does it catches on the side of the rear cover ring and eventually falls off inside the lens. Best to replace it - a small piece of heat shrink works nice. Or you could leave it off completely, it doesn't do a lot if the flex is properly stuck in place to the guide it sits on.
In order to avoid desoldering the old connectors from the engine and the cell, at the risk of destroying these components, I adopted another much more reliable technique. The pins, where the connectors are soldered, protrude a lot. So all you have to do is cut the old connectors flush with the components and position the new one on top. Then make the soldering points and that's it. No damage and much faster. In French "Afin d'éviter de dessouder l'ancienne connectique du moteur et de la cellule, au risque de détruire ces composants, j'ai adopté une autre technique beaucoup plus fiable. Les picots, où est soudée la connectique, dépassent beaucoup. Donc il suffit de couper l'ancienne connectique à ras des composants et de positionner la nouvelle par dessus. Puis faire les points de soudure et le tour est joué. Pas de dégats et beaucoup plus rapide."
Some people do that, and I understand that it is easier, but that technique could make the cable sit higher which could cause some problems with some lenses (for example with Canon 24-105mm L lens for sure.), also I don't like that the end of the cutted cable might touch metal elements, causing shorts, so I prefer to completely remove the old cable and put on a new one... I consider that a more professional work.
Your videos are really good and helpful.
Thank you for your comment, I'm glad you like it!
