Some prices have come down, mostly on the rarer collector lenses. But I think most of the prices on Nikon RF are similar to what they used to be. I bought a S2 and 5cm f/1.4 for about $350 in 2008. You can get roughly the same deal today (I just bought a body for only $120 but it needs some work). Of course when you account for inflation the price has gone "down."
Around 2010 I paid $650 for a M2, and that was when you could pick up a M6 for under $1K. I think there is a lot of interest from younger generations in mostly Leica gear, since those prices have tripled in some cases, and it bleeds a bit into Nikon and Canon RF gear. But it's definitely a great time to buy more Nikon RF gear. I try to buy some from members like
enasniearth every time they're listed in the classifieds, and I've been fortunate to get some nice deals from many forum members!
I feel like I ought to share my Nikon RF collection in this thread. I have bought a few new items since I took this photo a few weeks ago, including an S2! The Nikon RF system is not as diverse as Leica LTM or M, but there are still many avenues to go down and lots of fun lenses to explore.
