Impressive images. Question, how does the 600mm function with extension tubes? Does Sony make an extension tube? My reason for asking is that I'm interested in photographing hummingbirds with my a7r4 and would like to get a magnification of about .25.
My previous system was a Canon 1dsmk3 with 300mm f2.8 with about 30mm of extension tubes. The image quality was great. I don't see a 300mm f2.8 in Sony yet.

Hi Dan,
I do not have the 600mm myself. As to your questions regarding extension tubes though, Sony doesn't make any. May of us are using the Kenko extension tubes for the Sony FE mount. Part of their benefit is that with a little surgery they can be used so that the telephoto and zoom lenses that can use the 1.4X and 2X TC allow both TCs be used with the extnsion tube sandwiched between them and still offer AF and metering. Of course, when using the extension tube between both TCs, the lens can no longer focus to infinity, but this does have application for closer subject matter.
