I did some work recently while I was between jobs, designing and assembling camera lenses. It was so fascinating, and satisfying. Strongly disappointed they couldn't afford to pay me to stay.

If you’re going to go through all that trouble you may as well just use a lens or cam body with a quality, built in AF. Way cheaper and the tech has matured greatly. Plus even with lower to midgrade cameras it’s easy to find a capable system with a solid codec you can color match enough with the rest of the movie. Even my GH6 I travel with can shoot 5.7k pro res
I was talking about movie-grade setups, I was wondering why they need the sonar thing if they focus manually anyway. Maybe it's useful for post-production, as a depth field or something.

I don't use anything sticky, but if it's my first time opening basically anything, one side of my working space becomes a map of the screws. Roughly in the layout of the way they came out. Top to bottom, in layers, as it comes apart. A habit from working on laptops in a warranty center. I might have to try some tape.
Maybe the best idea is to make a video of the disassembly process, so you know exactly where what part went and in what order and orientation.

#84This is the kind of thing I'd love to see robots take over. Companies don't want to service these things much; the labor is too costly. They could just distribute the repair manuals and we could get robots to do it.
If companies could just distribute the repair manuals I'd be happy as a clam :D I'm all for automated repair!

#85The TPS62140's 30ns propagation delay is not enough to blow a fuse. The first rule of fuses (which many modern engineers do not understand!), is that fuses are not there to save your parts, and they simply will not do that. Fuses exist to prevent fires. Even a fast fuse is very, very slow compared to semiconductors. I've seen transistors blow up to "protect" fuses . They're for stopping fires and preventing the slaug…

I suppose it depends on the system? I have updated Sigma, TAMRON, and XiaoYi lenses on my Panasonic and Olympus MFT bodies, as well as Panasonic and Olympus with each other: https://support.jp.omsystem.com/en/support/imsg/digicamera/d... (Sadly not an exhaustive list. I have firmware for several more lenses stashed away in my archive, but the upgrade mechanism is the same.)
I shoot the m43 system (have since the GH2, then E-M5, E-M1, and now a G9 II) and didn't realize this. I only have one lens tight now (I tend to stay small on my system but this is a low point) but I'll keep it in mind. Thanks for the info!

Here's a counter-example, too: Metabones EF↔MFT speedbooster that has its own USB port and update+config app: https://i.ibb.co/t7mDFLJ/image.png https://i.ibb.co/PsSH2M3R/image.png

This is an overcorrection. Wrong because you've gone too far in the other direction.
