I was that close to pull the trigger on a great condition 80-200 f2.8 Af-D, but then I realized that the, again manual focus, 80-200 f4.5 just sits in a shelf... But heck, is that old thing sharp, I'd say on par with the 50mm.
Regarding teleconverters, the old 300mm works incredible with the equally old 2x TC, the 1.6 AF TC had worse image quality. And telling the camera that it is a 600mm f7.1 lense gets exposure just right, shooting handheld at ISO 200-400 for stills and 800 for birds and such gets quite some keepers. It does lack the flexibility of zoom, I love this 300 regardless. It is such a master piece of precision mechanics and optics, without any electronics, that I don't even miss AF. Well, most of the time that is...
I like the fish-eye shot with the shoes in it! Just thinking of that problem with a camera where the VF only shows 95% of the image...
Are those Kenko rings any good? I'm asking for a friend with occasional bouts of GAS...
And then there was '09 after I was laid off and just drove around for a few months.
Outside of that... I really haven't had the time in the past several years to take a dedicated chunk off and just go. Maybe this year.
The Kenko rings work fine for AF lenses (G lenses have some difficulty). Two of my photos from long ago shot with 'em:

I'll look for some used, affordable Kenko rings then, the only G lens I have is the 24-120, all others are either AF of Ai-S ones.
For my Nikon 35mm cameras... I have a 16mm f/2.8 fisheye; 17-35mm f/2.8 zoom; 35mm f/2.0; 50mm f/1.4; 85mm f/1.8; 105mm f/2.8 micro; 135mm f/2 DC; 70-200 f/2.8; 80-400 f/4-5.6 VR; 200-500mm f/5.6
The 80-400 is very nice and I used it for a long time but when I got the 70-200 (I have, though it is in the car bag rather than hiking bag) the 80-400 just doesn't have as much of a place.
The 16mm I'm not even sure where it is now - it was too easy to make mistakes with it ( https://www.deviantart.com/shagie/art/Fisheye-Oops-2767240 ) - the 180° field of view means that straight down is straight down - lean out and do funky tripod setups to avoid having what is straight down show up in the frame.
And yea... Nikon... I've also got a Maymia 645e with 3 lenses, Hasselblad XPan with 2 lenses (I just couldn't justify the price tag on the 30mm f/5.6), and two Horseman 4x5 (one field, one rail) and I typically have the Nikkor 210mm f/5.6 on it though I've got a shorter lens too - just that one doesn't have the image circle allowing for useful movements... I think it's a Schneider 135mm f/5.6, but I'd have to check. The common design for a 135mm has a 200mm image circle while the Nikkor 210mm has a 295mm image circle - and that's a big difference.

Another thing to do with the shallow depth of field is to get some extension tubes. I've seen photographers use the thinnest extension tube for some shots so that it reduces dof (it gets into macro equations), but not too much that they loose too much distance focus. And since there's no glass in there you're not degrading image quality with another refraction (compare teleconverters).
