I just picked up a 1DX MK III for $2,000. Which is insane. There are a lot of deals to be found on EF mount gear. I had been buying EF Primes right before the RF mount came out. Decided to complete the set. I don’t regret that at all. I picked up an R6, and they all work flawlessly on it. I only have one RF mount lens so far, which is the 100mm macro, and I do love that lens. The EF macro could be an odd duck sometimes. But my favorite lens of all so far is the 180mm EF Macro lens. I do love that you can adapt nearly anything to the RF mount. I use Canon FD, FL, EF, R, RF, Rangefinder, and even C mount lenses on my R6. I usually have an FD lens on it more than anything else, and have been using my EF primes on the 1D MK III, and 5DsR. I also got the 5DsR for $600, which is crazy cheap for that camera. I kind of over did it and got into collecting the 1 series bodies. Most at local shops on road trips. I now have the entire film and digital 1 series line. All work great. It’s a lot of fun to take the latest lenses and put them on a 1v and see what they will do, or to put these lenses from the 60s on an R6. I think Canon was really smart when it came to keeping the EF mount from film to digital, and later makeing the RF mount so easily adaptable. I still have an M5, and that’s a great little guy to adapt FD glass to. Compact. Wish they would have kept that line alive just a bit longer. All these cameras, and probably 20% of my favorite shots come from my M5, because I can take it more places with me, and toss it into any bag easily. Fits in my GF’s purse, so she borrows it a lot. I use a c70 a lot too. The RF mount on that has allowed me to be so more creative when it comes to lens choice without having to look at super expensive PL mount lenses. Leica, Zeiss, Nikon, some soviet things, they all fit with the right adapter. Once I had the lenses I ended up picking up an F1 and a T90 as well. It can be addicting.. But I’m going to do a full review of the entire Canon flagship lineup from the first F1 all the way through the R1. Been rotating through them at zoos and events at the moment.
