Their second-hand price has fallen to the point where I would be tempted, but apart from better battery life (I carry two anyway) and somewhat better low light performance I can't really see much benefit, particularly as the Google Pixel phone camera software handles low light landscape stuff for me now in a much simpler way than faffing in a photo editor.

The downgrades would include finding decent CF cards again, worse focus, lower continuous shooting rates, and fixed screens, as well as the stuff I'd expect, like being heavier and just under half my lenses only giving APS-C coverage anyway.

I like using the A900 more than the SLTs, but the sensor wasn't competitive at high ISO when it was released. Mostly worse than the A77II in low light. The A580 might be slightly better than the A77II.

The best A-mount camera deal currently is the A7II + LA-EA4 and/or LA-EA3. The sensor is somewhat improved over the A99. Less AA filter and more efficient 5-axis stabilization makes every lens sharper. Only 2.5 FPS AF-C in bursts with adapted lenses.

An A7S or A7III are the best low-light options.

Low light quality: I am happy with the A77m2 at 1600iso, I kept the A900 below 1200iso.
CF-cards: decent CF cards are available.
Focus: the centre focus point of the A900 is better then any of the A77m2. However, as a system the A77m2 is better - I would call it a draw.
Frame rate: if it is important, it is important. 5fps is fine for a lot of people.
Fixed screen: as the A900 does not offer live view, it is a non issue.

The A900 is a completely different camera. It basically is a film camera with a sensor inside. You really cannot compare them. If you like a optical viewfinder, the A900 is the camera to get. If you want a more basic camera, the A900 is better.

If you like the Pixel so much for landscapes, the advantages of full frame have very little benefits for you. Stick with your A77m2.

Apples and oranges. The A900 and A850 were meant to be studio workhorses, despite what others might say they were competitive, just not compelling. I like and use the A850. In good light with good glass it's an "old school" joy to work with.
The A77II is for getting outside and tracking something medium sized moving moderately.
I like the a850 for portraits. I like the a77 for birds. I haven't warmed up to the a77II yet (I got it for Christmas).

I'm surprised, given the larger pixel size and the absence of the mirror, but that makes the decision easier.

The A580 might be slightly better than the A77II.


I did attempt to buy an A580 at one point, but I was sent an A58 which is not quite the same thing...

The best A-mount camera deal currently is the A7II + LA-EA4 and/or LA-EA3.


Annoyingly, for someone looking to buy, the A7II seems to have kept its value quite well.

It is an attractive deal brand new. I bought it with the 28-70 OSS at the current price a bit over a year ago at a local camera store. I do plan to eventually sell it, so hopefully the value keeps holding up.

I use both the A850 and A77ii. They are different beasts for different burdens. The A850 is wonderful for landscapes and portraits, as long as I keep the ISO down. I prefer to use it at ISO 200 with a tripod and mirror lock up. There is something charming about it that is hard to explain.

That being said, I find the A77ii to be a better all-around camera. It does what I need it to do with no complaints from me. Granted, I am not trying to track fast moving objects or shooting in extremely low light conditions. There are newer, better options for that. But If I had to pick between the two, I would go with the A77ii.
To see is to enjoy. To see beyond is to rejoice.

The A580 is nowhere close to the A77m2 apart from maybe the low light performance of the 16mp sensor that you also can find in loads of other cameras.

The disadvantage of the A7II is that you need to use adapters to mount A mount lenses.

I agree with everything Basil said.

I'm surprised, given the larger pixel size and the absence of the mirror, but that makes the decision easier.

While pixel size and the mirror which eat some of the light are factors in the ISO performance, the technology is an even more important factor and because of that the newer camera is better with regard to high ISO.

Generally, I still keep my A900 and enjoy using it from time to time although I have many newer (and generally better) cameras.
As already said above, the central focus point of the A900 (and A850) is the best AF you can get, but it is the only useful point in A900 while in the newer cameras all the focus points are equally good.
The image quality and dynamic range of the A900 at base ISO is still relevant (not the best, but relevant) in these days' standards (and if you think how many new cameras and technologies came out since the A900 it is quite amazing that it is still relevant) and the handling and operation of the camera is a joy for me (but it is a subjective thing...). But as said, it is not there in terms of technology and overall the A77ii is a better camera.

I know it is a rather common belief that pixel size influences “ISO performance”. However, I think it is because many find it difficult to grasp that image level quality might be improved even if the pixel level performance is worse and get fooled by pixel peeping which inevitably results in false conclusion.

As a photographer, I find it much more interesting to look at images rather than pixels. Do the same and you will soon discover the small pixels are worse fallacy.

i have a900 & a992. my opinion would be a900 would be downgrades compared to a772, unless you only need to shoot at <= ISO-400 at all times.

a900 pros: great viewfinder, better battery life.
a900 cons: huge, heavy, ancient AF system, no video.

the base-iso colours may be better. I dunno about the a772 dynamic range, but the a992's highlight and shadow recoveries are amazing in comparison, as it should since its 8 years newer technology.
