May I offer an update re the 2.0x teleconverter. It is stated in the excellent lens summary above that you lose phased contrast detection when coupled with the 50-140mm lens. Actually - it does keep contrast and phase detection. You do lose phase detection with the 100 - 400mm tele when coupled with the 2.0x because it cannot get enough light through. I have successfully taken high speed focusing shots in low light with the 50-140mm with the 2.0x converter so I thought I'd give this update.

thanks for your excellent lens summaries Quincy. May I add a tad more on the zooms? The 50-140mm zoom has the additional benefit of using both Phase and Contrast focussing with the 2x teleconvertor whereas the 100-400 is restricted to contrast focussing. I used both the 100-400mm and the 50-140mm lenses with the 2x converter during a trial session with Fuji in low light. The result was conclusive for me: the 50-140mm nailed the focus rapidly every time while the 100-400 hunted. So in limited light I think the 50-140mm plus 2x converter gives the wildlife photographer more scope than the 100-400.

thanks for the reminder re MS+ES mode disabling PDAF! But I don't really understand why this needs to be a user intervention - couldn't the camera use PDAF when the camera is using the mechanical shutter and keep doing so until the aperture and light combo pushes the shutter into ES mode and THEN have it auto disable PDAF at that point? Now I have to keep switching ES on when shooting wider aperture with the F1.2 in sun. I guess though that the rule is if shooting any moving subject then keep the shutter to MS mode only which I agree does make sense. Nice photo by the way!
