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: 800mm F8 quality. Overall optical quality, blurred, internal zoom It is a 200-600 elongated and improved throughout, with the zoom ring being slightly harder to avoid unwanted focal length shifts. Price, maybe not really for everyone, but still low

Cons: Weight!!! really too heavy to be handled and used freehand. A monopod is a must

Opinion: You could say that the 400-800 is a 200-600 gymnastic, with muscles but at the same time also well-groomed in appearance. Sony has not only thought about mass and strength but also about taking care of definition and aesthetics. In practice it is a 200-600 lengthened and improved in all respects, except unfortunately, by force of circumstances, in the weight, which has increased and is felt a lot. As far as I'm concerned, any freehand use is not only not recommended but practically "impossible". even it is easier for me to use and shoot handheld with the 400 GM, and with the 200-600, even if the monopod is always highly recommended, in all three cases. We know well that on the web and on this forum there are several Schwarzeneggers who go for days up and down the cliffs of the Alps with 95kg of equipment on their shoulders, 7kg on their arms and skis on their feet in winter or who go to Africa with 17 backpacks, 49 lenses and 25 bodies .... But in Schwarzenegger's reality there is only one ... and only in movies. Apart from this aspect, in practice the only "negative", the 400-800 is really a great super telephoto lens, above all, although not bright, it is a true super telephoto lens !! It's not half rubbish like the Canon 200-800... So much so that if the Canon 200-800 is totally absent in the professional field, the Sony 400-800 has already become widespread. In this case Sony was good because in no time at all it announced it and launched it on the market with immediate availability, contrary to what normally happens today ... with biblical waiting times. It is equally true that Sony fanboys, who have always been the most "technically cool" have not welcomed it very well (like the A9iii), since having always spoken badly of Canon and the tendency to build darker and darker lenses, they too found themselves with a telephoto lens F6.3 - F8.. A childish attitude .. because yes it's dark, but it's an 800mm !! F8 !! and at 800mm it maintains the same excellent optical quality as the 600mm. The optical quality is really very good, up and down in the center is that of the 200-600 but pushed up to 800mm where the value of F8 helps to reproduce really important blurs. At the edges and in the blur itself there has been a noticeable and clearly visible improvement, where the 200-600 appeared "sad" and withered, this 400-800 shows no weakness. The stabilization has also been revised and improved and you can feel it quite clearly right away. The autofocus is now so valid on all products, especially on the original Sony ones, that to say if this or that is a little better would require very specific tests that do not interest me .. As far as I'm concerned, everyone is more than fine. Maybe someone could complain because the sharpness has remained the same as the 200-600 and maybe (maybe!) the 200-600 at 600mm in the center and on "scientific" sights is still a bit better (100% on monitors).. But is there really anyone who would have the courage to complain? Come on... The 200-600 at 600 in the center is hardly distinguishable from a 600gm in terms of sharpness and the 400-800 is attached to the 200-600, moreover it reaches 800mm without showing drops and with a brightness of F8! But what are we talking about... Once again Sony proves (with OMSystem) the best choice for those who want to devote themselves to naturalistics, offering a boundless range of telephoto lenses for all tastes and all budgets, also thanks to the fundamental contribution of Sigma and Tamron ... Unlike Canon which does not even offer a single long lens valid below 12/14 k for those who want to devote themselves to naturalistic .. My hope, as a Canonist, is that Canon can bitterly regret this wicked choice as soon as possible

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.
