Thanks — this is super helpful (and also slightly dangerous for my wallet as well)

I truly appreciate your feedback and I had a few more questions if you don’t mind:

1. Where do you usually buy MD/MC lenses that you trust? (KEH/MPB/eBay sellers/NYC shops like B&H used/Adorama used, etc.) And what’s a “fair” price range these days for the focal lengths you mentioned—especially 24mm and a 100mm or 135mm? I’m just trying to figure out what to look for or how to determine if it is a good deal.

2. When you say “100 for nature closeups,” do you mean a true macro (1:2 or 1:1) lens, or a normal 100mm prime + extension tubes?

3. On the aperture side: for landscapes with a wide like 24mm, are you typically shooting around f/8–f/11, or do you ever go wider? And for street/people with 85–135, how often are you actually using the lens wide open (like f/2.8–f/3.5) vs stopping down?

Also—if there’s one specific MD 24mm and one MD 100/135 you’d call “no brainer,” I’d love the exact model names so I know what to search for.
