Cross post from the Fix it quick questions thread.Wrr posted:Got a DSLR camera lens which seems busted; the bit that turns to adjust focus / magnification won't turn (feels jammed) and uh, also this piece is rattling around inside. It is a mystery to how this may have happened, and any relation to me knocking the camera over while high is purely conjecture. Update: piece that is bouncing around in there:

Thats really really impressive work. Good job dude Did some more work, the loose piece is this flare cutter, which looks like it opens the aperture on the front of the lens? The real problem is that the camera is stuck at 55, max zoom, and I can't get it to move. Not sure how much of this lens I need to dismantle to get to the parts I need to get to. I'm looking at needing to desolder a few bits, which I don't love. Removed Straight Keys  Zoom now moves half of its range, but it appears that its out of sync with where it should be     Like, the dots and indicators are moving in sync with the silver / gold contacts section, but the lens itself is out of wack. When I first had this problem I was manually rotating the lens itself trying to figure out why it was moving but the zoom adjustment ring wasn't, so I think I did some damage there. Need to keep digging to figure it out, but any tips would be massively helpful. This is uh, my first camera and I've yet to take photos with it. Edit: Got the second lens group out, placed the flare cutter back on where it looks like it should be. The mechanical aspect of the zoom now has a full range of movement. What is interesting is that it goes out, in, and back out as I move it through the range. I assume that is normal, but it did surprise me. https://imgur.com/a/kWsTRua Video of it in motion. So, I think I can start to reassemble things; should I have the zoom set to one extreme or the other as I do this? Wrr fucked around with this message at 18:14 on Sep 5, 2021 |
