I have the Canon 500 F4 today so now begins a long period of learning. It is a daunting piece of equipment.
Yes Darren, I use the 1.4 tc a lot and see no degradation of IQ. Artie gets excellent results with the 2x tc as well and I have a theory that the oft-talked-about loss of IQ with this tc is all about photographer technique and not to do with glass.
