I buy pretty much all my gear second hand, and I haven't seen prices change much recently. I do keep an eye on the used market, although I'm not really looking to buy anything in particular. (Mirrorless prices cured my GAS.)
Here in the US, we're just beginning to see tariffs take affect on new gear, and new products usually take a year or two to start showing up in significant numbers on the used market. Other than when they released the R5ii, I haven't really seen prices on used Canon gear change much, up or down, since I put together a mirrorless kit 2 years ago. While there are a couple of Mark II bodies out there, as far as I know, all Canon RF lenses are Mark I.
In the last few years MPB has used venture capital to try to corner the market on used camera equipment, so they play an outsized roll in setting market prices. If they start passing along tariff price increases to both sellers and buyers of used gear, regardless of the original purchase price (tariff or no tariff), then market prices in general will go up.
The biggest change in used prices generally comes when a new model is released. I bought a used R5 classic when it was still in production. When the R5ii came out, I bought a 2nd R5 body for $800 less than I paid for the first one. That may be what's happening with the R6ii. An R6iii is rumored to be imminent and that's affecting prices of the R6ii. That will also affect used prices, but the real hit will come when the R6iii is officially released.
- ongoing Canon (UK) and Wex offers have sealed my fate.
