The R5 and 600mm f/4 continue to amaze me. I am easily shooting better photos than I did with the 1DX Mark III. The autofocus is better, especially the eye focus that the DSLRs lacked, and the electronic shutter at 20 shots per second is helpful for the quick little head turns feeder birds do and the fact that it is silent. No longer is the sound of my camera making birds react that eliminates my chances to photograph them. I now have mostly mirrorless lenses but continue to use the $100 adapter to use my Canon 65mm macro, 180mm macro, and the 600mm. I know the RF 600mm is on its way and so it the R3, but don't know when I can get my hands on them. A year ago I was mildly interested in mirrorless, mostly from a teaching perspective, but now I am convinced mirrorless is here and switching helps me shoot the images I seek a lot. I realize it cost $$$$$ to switch, but I see no point in denying the mirrorless advantages. Heck, I don't even have to AF microadjust the R5, like I had to with all my other DSLR. For 45 years I shot macro, landscapes, and wildlife all over the world and never did I think new camera gear would help me out so much, but it has happened.

I have only used this mirrorless R5 since I bought it in early Nov 2020. Since then I have not used any of my DSLRs. I simply won't give up the mirrorless advantages. I know you can get fine photos with DSLRs, after all I used them for 20 years to earn a comfortable living, but mirrorless works for me better. By the way, the R5 is also super for small birds. All the small birds I posted here were done with a 600mm and the camera set to 1.6x crop mode giving me the field of view of 960mm. I am finding the crop mode to be most useful when I need the subject larger in the viewfinder so I can monitor its activities and know when to shoot.

My article on using this combination for wildlife - R5, 600mm, 1.4x teleconverter, and crop mode is found at the following link.
