Pros: Sharpness, internal zoom, autofocus precision, stabilization and weather sealing, reasonable price.

Cons: If we really want, the foot to be changed immediately, so as not to accidentally stop the focusing.

Opinion: It's sharp, yes if it's sharp, even with the 1.4 x extender (which is really well done) which allows you to reach 1120 mm. The weight ? As far as I'm concerned, I lightened up, I was shooting with the Canon EF 500mm f/4 L IS II USM with 2 x extender and adapter for Canon R (3.3 Kg. vs. 5.2 Kg.). But above all (and this is the reason for the purchase) I now have a zoom, the lack of which was a real worry for me, as a walking photographer, rarely stationary with tripods. Very satisfied, in the last photos of fauna he passed every exam, even if f/8.

Pros: Good image quality, improved blur and, compared to the 200-600, decent correction of lateral chromatic aberration. And... 800 mm native usable freehand. A lens that does not lengthen with zooming. Faster autofocus than the 200-600.

Cons: Weight higher and shifted forward than the 200-600. The lens hood accentuates the problem. Ultimately, handheld traversing is more difficult than the 200-600, especially with intensive use. Better in this case to remove the lens hood. Usual short and uncomfortable foot also to carry the zoom on the move.

Opinion: I used this new telezoom for four days on a small island and a week in the heronry. Until recently, a native 800 mm weighing two and a half kilos 35 centimeters long, and without elongation when zooming in, was unthinkable. I think it's a lens that changes the possibilities of wildlife photography handheld. Like the 200-600, I also used it while seated to photograph large insects and small birds such as flycatchers and golden orioles in flight. It is more challenging than the 200-600, I do not recommend it to those who are beginners in naturalistics. You can have the illusion of getting great shots at great distances, which is obviously impossible except in favorable conditions of low temperatures and low air humidity. Image quality similar to the 200-600, but in addition it is already excellent at full aperture at 800 mm. Noticeably faster and more accurate autofocus at 800mm, compared to the 200-600 with 1.4x. Easy for those coming from the "sacred zoomone" to operate the zoom ring during bursts. I recommend framing the subject at 600 mm, and then varying the focal length using even a single finger. Once the subject is framed, the crop can also be used in the camera thanks to the good stabilization. Essential to obtain sharpness without grain, the use of AI denoise algorithms. You can see below a series of rather difficult shots that I took with this telezoom. As I mentioned earlier, I recommend it to experienced users.

Pros: Focal range for birdlife and wildlife (if you find yourself using focal lengths greater than 400mm). Image quality and stabilization. Full time manual focus, autofocus and GM-level build quality for the mechanical part. Zoom in

Cons: Price, (but I already had a nice discount) even if it is better made than my 200-600, weight and size (compared to the Canon 200-800). Non-Arcaswiss tripod foot, more solid than the detachable one of the 200-600 but not easily removable (it takes 4 Allen screws to remove it). f/8, is not f/6.3 at 600mm (7.1 at 590). The click (as well as on the 200-600 and 300GM) of the collar positions is missing. Some like it, others don't. Sigma did well with the 300-600 f/4 to make it selectable. A bag like the one of the 200-600 is missing.... ;-(

Opinion: Today the first rehearsals around the park of the temple of Naritasan (Japan). The lens is slightly front heavy, but it handles hand-held well and without problems. It's all more or less what you can expect from a quality zoom from Sony, very very similar to the 200-600 but obviously it's slightly smaller and lighter. They have finally improved the lens hood and its attachment (the one of the 200-600 is in my opinion not up to par). Very similar to that of the 300GM with the white release button. The AF, limiter, etc. controls are all "GM", the focus preset is missing (as on GM supertele) with the relative ring for prefocus recall. I still have to study it a little, but I am cautiously satisfied. I propose an update of the review later, especially comparing it with the little brother 200-600 and with the 300GM with multipliers. And of course with the Canon 200-800. I took the photos by pairing it with an A1 mark II Note: I don't see the photos I took for now with this new lens.
