Re: RF extender experiences with RF 100-500 1.4x vs 2.0?

1.4x with the 100-500 on the R6 is great – zero loss of sharpness that I can tell. 700mm with a mild crop is about perfect for distances of 15-30' for small birds. Beyond that, you're going to be cropping uncomfortably far with the R6. I've not tried the 2x, but given the high IQ of the 1.4x, I'd guess the 2x is probably not that bad. Of all the 100-500 + 2x talk I've read, it's been only conjecture or anecdotal without examples.
