You will find it challenging to use a long zoom on a moving, vibrating boat. You also have mentioned mobility issues. Perhaps your best success will be shooting only in bright daylight with a high shutter speed. The fast lens on the FZ200 also helps facilitate this. Shutter preferred auto mode and 1/1000 or so might work well. Be sure, of course, that image stabilization is turned on. Tripods are a nonstarter on a smallish riverboat, but perhaps a monopod would be helpful.

I have a similar bridge camera, a Fuji S1 that I have had remarkable success with on boats/ships, given the tiny sensors of these cameras. Despite their drawbacks, those little sensors also give tremendous depth of field which is beneficial to shooting distant landscape and cityscapes.

Yes, the people look like simple drawings instead of a photograph...WAY too much smoothing. There are worse things than a little noise. The original photo is quite impressive for ISO 25,600.

As have I. Over a decade of use now for myself and numerous others, several successful recoveries of many files, historical versions kept indefinitely (and they work), good interface, light resource usage, good price.

IDrive...Highly recommended.

Indeed. I once saw a tiny LI laptop battery ignite when its case was punctured. It was pretty astonishing to witness.

In that case, stick with DX. With an FX body, your crops would grow even more extreme using your existing lenses, including your long FX zoom. Birders love the D500 for its DX "reach" and overall speed. Your D7500 is a very similar camera.

None of the options you're considering are better for birding or planes than what you already have. Worse, in fact.

Nope. Nikon won't touch it at all, nor will they sell parts to an independent repair facility.

Yep. They're great cars, but they won't cut your ownership cost much, if any. The numbers speak for themselves. My next car may well be a hybrid.

I'm glad you like your Prius, but its ownership cost is not half that of a comparable non-hybrid car, in this case a Corolla Hatchback. The total cost is about the same for the first five years. Beyond five years the numbers begin to favor the non-hybrid car, which lacks the battery replacement and system complexity issues all the more. This Edmunds calculator is very illustrative.

I'd love to see the math behind that claim! LOL!

Don't use homeowners insurance to insure your gear.

In some areas (coastal) companies are dropping homeowners customers for any excuse. In the Gulf states home insurance is hard to get, very expensive, and is easily lost. The only sure way to hang onto your homeowners policy is to never make a claim. You make a couple of petty claims and it will get noticed. Many have lost their insurance in this way. No, it's not just, but it's real.

This is an informative video made by one of our members that may help you decide if you want, or need, filter(s) on your lens(es).

I had a very good experience with Samy's...a used lens.

That's generally what "refurbished" means, a new item that was returned for some reason other than dysfunction, and checked for proper function and cleanliness. Boom...refurbished! Drives, cameras, coffee makers...whatever.

It makes no economic sense to go any deeper into the product to troubleshoot or replace parts. Expert labor is expensive.

Some of these people were in great bands, or were great singers, or great song writers, were very well known, but were very ordinary guitarists. There are MANY guitarists out there who are much more skilled than many on this list. Clark, Kotke, Pass, Campbell, Ritenour, Montgomery, Di Meola come quickly to mind.

Then my suggestion is not going to be useful. It's an easy matter if you know a Linux geek who could help.

Best of luck...
