Sony A9 at 840mm

Sony A9 behind 200-600mm zoom with 1.4 tele extender. Some so called experts appear on YouTube and are critical of this lens with an extender on this camera, but I think the resolution and color are quite good and comparable with the Nikon D850 with the 500mm F4 with 1.4 extender

I believe some of them are jaded because they were comparing it to the 600/4 that was released alongside it. In that light I can understand the “let down” but I’ve always thought that this was an excellent lens. About my only “complaint” is that they didn’t stick to a constant f/5.6 aperture throughout the range.

I agree with your comment regarding the aperture; nevertheless, look at the bokeh the lens provides at 9.0 (because I had an extender attached). I find the lens sharper than the Sony 100-400mm
lens without an extender.

Yeah I agree that optically they’re close enough the decision will come down to h th e focal length. The 100-400 focuses a bit faster and may be a tad sharper... but I find them to be extremely close in performance. To get a noticeable jump in quality I think one has to go to the 400 or 600 prime lenses that’ll run you about 12x the price.
