Stay at home

Canon has been a little bit naughty about its information about the mfd of the RF 100-500mm. The mfd at 500mm is 1194mm, and 971mm at 100mm, as measured by TDP and which I also find at 500mm. Having written that, I have to say the 100-500mm at 500mm is really good close up, and even better than the 100-400mm II, especially when 2xTCs are used. The RF at 1000mm is superb for close ups of insects.I was impressed when I checked the MFD/mag of the EF100-400mm vs RF100-500mm ie 980mm (.31x) to 900mm (.33x) with the latter being @ 500mm. Reduced weight, collapsed size, stability and AF speed are bonuses. Would you upgrade to the RF100-500mm or stick with your EF100-400mm if Canon released a crop RF body?
