Pros: speed and image quality

Cons: bit small for big hands

Opinion: The A9 is a camera that was not within my reach, but now that the A9ii has arrived, it has become affordable on the second-hand market. compared to, for example, Canon 1DX, it is also much more affordable. I come from a canon 1DX and switched to sony A7Rii of which I was super happy with the image quality but the AF was insufficient for bird photography for me. The A9 I have now several months and I regret that I have not switched earlier. the AF is really super aim and it grabs the bird, you just hardly miss a shot! And if you miss it, it's just the photographer's fault. Especially because it is also silent and you do not feel that you are being looked at by everyone around you, for example in a zoo or bird show. even in a shed hut situation, the birds simply do not know that you are there so that you will only see natural behavior. I also expected that the 24 MP would be too small, but the quality is so good that there is still a lot of crop space left, even compared to the A7Rii that I keep next to it for landscape and building photography. Buffer is also great, it just never gets full, only drawback is that you can not quickly change things. You have 2 battery for 1 day more than enough. only drawback is if you have some big hands you have to get used to the compactness. Weight is okay, better than the 1dx that always hung around my neck like a brick. Together with the 200-600, this can now simply be maintained all day long. Noise that you eventually get (6400 ISO) is good to polish away.

Pros: Af, Raw files, ergonomics, dynamic range, battery life

Cons: Not being the Alpha 9 II?

Opinion: Given that I am able to use it well below its potential, it is a joy to photograph with this machine. I do not dwell on the precision of the autofocus for which I needed a period of learning while coming from other Sony bodies: once I got to know each other I ventured things unthinkable in previous years. Excellent Raw files, very well workable especially in recoveries from underexposure, good dynamic range. In combination with fixed optics can give great satisfaction. The 24.2 megapixel resolution for me is the right heaviness. Instead compared to the A7 III I had very high expectations on the response to the high Iso, however the files up to 3200 (with peaks at 6400) are easily workable in post. Good battery life, good ergonomics, excellent viewfinder, burst and absence of blackout. The menus are the usual Sony, now I have known them for a few years. The only real flaw (perhaps) is not having the processor of the A9 II, but for that, in fact, there is the A9 II.

Pros: Very fast focus, operating speed in general, direct buttons to access many functions, large, bright and very nice viewfinder, good autonomy to be a mirrorless and much more.

Cons: Ergonomics, menu that must be "studied", at high iso did not convince me

Opinion: I kept it for a couple of weeks and my more than a review is an impression of use. Camera with crazy operating speed and lightning fast autofocus. When hooking in af-c it no longer releases the grip. For those who have doubts about the mirrorless viewfinder should try this. Big, bright and very true to reality unlike the OM MK3 I had. Excellent file quality, very sharp and clean. Very good dynamic range, allows for nice recoveries. The menu is nice elaborate but very customizable and once set to your liking it becomes very usable. The camera body is built very well but is compact and not very ergonomic, it seems that a piece is missing at the bottom as the little finger remains free and without support. The handle is close to the bayonet which is uncomfortable to hold. For those with medium-large hands like me, the battery grip is a must as it is uncomfortable even with normal or small lenses such as the 16-35 f4 and the 85 f1.8. It did not convince me completely at high iso, with the D780 I certainly did better at 6400 ISO, but also at 3200. In the end I sold it because for the genre I like (landscapes and portraits) it is wasted. I await the more generalist A7 III and I have some money left for a nice goal.

Pros: Excellent focus, high iso seal, workable raw, burst, no blackout

Cons: without a grip the handle is for small little hands, but it makes you forgive! small delay when assigning functions to programmable keys. but thinking about it better the only real downside is not having bought it before!

Opinion: use a9 mainly for nature photographs, birdlife, etc.; associated with Sony's very honest 200-600 forms a truly excellent pair. The only "flaw" I see is a slight delay, pressing the button programmed for an alternative focus (type from center point to zone, etc.), delay more in graphical display in the viewfinder than actual focus gaps; for the type of use I mentioned (birdlife and animals in general) in my opinion, among the mirrorless, it is second only to the brand new a1... the high isos are among the elements that make the 24 mega full-frame layered CMOS sensor formidable, as well as the incredible speed and absence of blackouts (try to believe!!!). a9 is an extremely versatile machine body, valid in many types of shooting, still current despite the fact that the project is now dated for this sector, today it is purchased at very "advantageous" prices compared to the presentation period. I prefer it to all the cameras I have had in the past, I will cite the main ones by comparison: Nikon D750 (excellent!!!) D810 D500, Sony a9 is as if it's joined and improved them in one machine.

Pros: Crazy overall speed, amazing focus, sufficient dynamic range and widely average. Battery life, very manageable Raw, high iso

Cons: Focus with little light and little contrast

Opinion: I waited a year before doing the review. A year where I was back the desire and beauty to photograph. And the A9 on this contributed as Well I admit, passed in a short time the problem of the menu (in my opinion nothing impossible and with a moment of patience you learn everything), set the function keys, the machine seems to come to life its own so much it is easy, pleasant and fast to use it. Very light body, well tropicalized, perfect with battery grip. An epochal jump from the canon 6d I had.
