I use Canon 90D and am looking to hear about direct experiences using the below lenses and converters.
I'm wary of convertors but I hear the new MKIII have less issues with IQ and AF than previous models.
Canon 500mm f4 MKI plus 1.4x mkiii seems to have a good rep for results. Any idea how those results compare with Canon 400mm f2.8 MKI and 2x MKIII obviously 800mm f5.6 sounds lovely on paper but I'd rather not sacrifice IQ and AF.
Both combos would be similarly priced on the second hand market.
If this is covered elsewhere please point me to the thread.
Cheers
Rich
