Do you know of any manufacturers that still make (or have) interesting lenses for F-mount?

No. But Nikon made so many good Ai-S lenses that you can find lots of them on eBay and other secondary markets. Note that for old lenses, price and lens quality don't correlate well. There are lots of fantastic old lenses that are cheap because they were produced in large numbers, and there are also a lot of optically shitty lenses that are expensive because they were rare or produced in smaller numbers and have coll…

I have been following the advice of others more knowledgeable than me when buying AI-S lenses off of eBay, and I have to say that even on the D850, all of them have performed surprisingly well.

However, I'd really like more "arty" lenses with AF. MF causes me to lose a lot of shots I wish I'd nailed.

I agree with you regarding press fit BBs, but aren't externally threaded BBs also better for casual cyclists and more reliable? I don't care in the slightest about BB stiffness and weight, but I would much rather have a BSA threaded external BB. That way if something happens and I need to change my cranks (or god forbid, bearings) I don't have to worry about needing a specialized crank puller or anything like that, a…

The bearings in external bottom brackets are much less well protected, and so more vulnerable to water and dust and so on. That means they need to be regreased or replaced more often. I see people talking about doing that monthly, annually, whatever. I have been riding the same square taper bottom bracket since 2012, and it's doing fine. The square taper per se may not be as good as a bolted spline or something. It i…

I've been riding the same external BB since 2015. The only people I've ever heard of replacing their external BBs are hardcore mountain bikers or people with exotic weird BBs. It's nothing special, just a run of the mill Shimano BB-52.

While the bearings are a bit more exposed, they're significantly larger which means they can be sealed better. In practice they are pretty well protected fully sealed bearings. There's not really that much of a reason they'd have to be less protected than internal bearings.

There are some products that turn MF lenses into AF, primarily targeted for video shooters. I haven't tried them though.
