I thought I would also start a new thread for this lens. This is the second RF lens I picked up. I have had it for a bit over a week. For a <$2,000 lens, I am very impressed. There is much debate as to if this or the RF 100-500 +TC is the best way to get reach. But, setting that aside, there is no doubt in my mind this is a very capable lens.
Bryan's review is here.

Biggest issue is AF hit rate in low light (less than EV 13). So, this lens needs light. But, if you have light, I am pleased with the results.
