I ordered an RF 85 F/2 in mid-October from Amazon at a time when they were suggesting that they would have stock available to ship "soon".
Amazon customer service is not a thing. There comes a point where they are so big they simply don't have to care about a few thousand unsatisfied people. As they put more and more small businesses out of business they know that you have fewer and fewer options. I stopped giving a dime to Amazon a couple of years ago. Ebay, Home Depot, Lowe's, Target, Best Buy, and even buying direct from a manufacturer can all be alternatives for things that are hard to find locally (many of those have local stock as well).
First, spend all the money you can at local small businesses and avoid chains.
Second, spend money locally if you have to buy from a chain.
Third, spend money at small online businesses that aren't chains.
Last, find an online seller that isn't Amazon.
And never give Amazon any money.....which means even coming to this website is somewhat dubious, but we can't avoid ALL connections EVERYWHERE all the time because it's just not possible.
After a month they asked me if I still wanted the lens. I said yes. A couple of days later they changed the status to "preparing to ship" and charged my credit card. Hurray, I thought. Two weeks passed and they were still "preparing to ship". A local camera stored had e-mailed me that it finally had the R5 and R6 in stock. They didn't mention lenses, but I thought I might as well call them. Well, they had the 85 f/2 on the shelf. After cancelling the Amazon order I zoomed over and bought it, and observed that they had several other RF lenses on the shelf behind the counter, including the new RF 70-200 F/4 L. So, if you are waiting and waiting and you still have a local camera store, you may want to give them a call.
Never buy anything from Amazon. They're business model is predatory pricing that is used specifically to put other companies out of business so they can eventually absolutely control the price without input from any competition. They bully their Marketplace sellers and publishers by holding their sales hostage. Their treatment of employees borders on third world practices.
Never buy anything from Amazon. Don't give them a dime. They are leading the race to the bottom and should be avoided at all costs, even simply not getting what you want.
