I regularly shoot water birds with a friend who shoots with a Sony A1 and 400/2.8 with 1.4x. This has tempted me to replace my RF 100-500L with an adapted EF 400/4 DO ii, probably most often with a 1.4x (either RF and modified adapter which I have or an EF 1.4x iii). I have an RF 70-200 to cover shorter focal lengths (albeit on a different body). I see the 400 DO as providing benefits in low light and in bokeh with cluttered backgrounds common in wetlands.
A 400/2.8 is outside my ideal budget, but is certainly too bulky for travel. An EF 200-400/4 (with inbuilt 1.4x) is too long and heavy. A Sigma EF 500/4 is similar in size to the 200-400.
Second hand EF 400/4 DO lenses are rare here in NZ and command a premium over the 200-400.
AlanF previously posted positively about his 400 DO lens.
So I'd appreciate thoughts on moving from an RF 100-500L to an EF 400 DO. Or maybe an EF 300/2.8 with 2x.
Thanks
