Ah, good to know it is suiting your needs. It is impressive just how good it is at focusing given how many years ago it was released. I really enjoy using it too.

The Batis 135/2.8 is a lovely lens also, but I get your point about range. I suspect odds are good you will have a long telephoto zoom sometime in the near future...

Iím absolutely loving it, best camera Iíve owned by a mile.

I was concerned on transitioning from the A7rii about the loss of MP, but so far havenít really noticed it, as the speed and AF performance more than make up for it - Iím getting far more keepers.

The only downside is that itís tempting me to do more sports shooting, and given my longest lens is the Batis 135, that means more spending ! Must resist!

So, just wondering how you are finding the a9 Andy?

Update - after much reasearch and thought, I found a used A9 in great condition in LCE in London. Picked it up today and canít wait to have a play with it!

Thanks for all the opinions - useful as ever!

Hi Andy

Yeah, that was the root of my dilemma. Was it worth it to spend a lot more on an a7iv when the a9 was still an excellent camera, and had a faster AF system. I lost a few other things I wanted (33MP file sizes, video options) but these weren't vital. So I got the a9 and kept the a7Riii.

And I can confirm the a9 is a very, very good camera. It's going to replace my a7Riii as my primary camera for events.

Thanks. Cost-wise, I could get an A9 for around £1,700 to £1,800 whereas the A7iv is £2,400.

I think the A7iv is the better option, but i need to consider whether better by £600-700, which isnít far off the point where I could have the A7rii and A9 for the same money as the A7iv alone.

Ultimately theyíre both great cameras, so I canít really go too far wrong!

I had a similar dilemma recently with shooting birds in flight with the a7Riii. I considered both the a9 and a7Iv (not as replacements, but as a second camera).

Overall, the a7iv is the better all-round camera. You also get bird-eye detection, which has not filtered down to the a9 as a firmware upgrade. You get better video options. But it was (at least in NZ), the more expensive option.

Where the a9 excels is AF-tracking. The stacked sensor processes the data it much, much faster than the a7 options. You also don't have any shutter black out, which again, for fast moving subjects, is great. The a9's 24MP file sizes also seem more than sufficient. I shot with an a900 for years (back when 24MP was a lot!), and am pretty comfortable with it.

It seems from your needs, the a7iv appears as the better option. It's a one camera solution that does everything very well. The only reason to get the a9 would be because it was cheaper and you really needed an AF-tracking system for sports and wildlife.

I have an a7rii too and got a used A9 about a year ago, used, for a better price than a new a7iii then. Now that the A7iv is released I've no inclination to get rid of the A9. Besides the obvious monetary reason I like being able to use the silent shutter always (incl indoors and panning on moving things) and I haven't found much to complain about regarding its resolution or AF.

It's much more fun to pick up than the A7rii but I only use some MF lenses that I quite like with the A7rii so I can tolerate it : )

Now my son is 3, heís moving a lot faster and is pushing the AF tracking, I also found recently during a few studio sessions that the AF struggled in the low light, and even missed eye AF a few times.

Itís got me thinking whether itís time to upgrade. A few years ago I did mainly landscape work, but now portraits and kids take more of my time, and as my son grows I can see the AF capability being more important, particularly once he starts playing sports.

I'm in a similar position, having the a7Rii for about 2+ years. For landscapes, portraits it's marvelous. For anything involving movement (actors, horses and birds) I've been using the a6600 with it's fantastic tracking AF. I've already made the decision to get the a7IV, just putting together the finances to do so.

Why the a7IV over all the others mentioned?

Start with 33MP and lossless compression in FF, which is 14MP in aps-c mode (I have the Sigma 1.4 trio and 7.5/2.0 TTArtisan fisheye). 42MP is just more than I need on a day-to-day basis, but a jump to 33MP makes sense to me.

Adding bird-eye focus to the excellent Human and animal eye-focus.

Full compatibility using the LA-EA5 with my many (way too many) screw drive Minolta & Sony lenses.

The FZ100 battery is much better than the 50's on the a7Rii, but is common now on your other choices. I may even pass on getting the vertical grip, something I have on most every other camera.

The a9 would have been better for me previously, but my equestrian shooting has faded to only occasional, so the speed of the a7IV is all I need anymore.

I don't do much video, but plan on doing more. This seems the best platform currently available for my needs. Hardly the deciding factor, but it is a plus. However when I do choose video, the switch for stills, video and S&Q is a great addition. Keeping the functions separate makes considerable sense.

The only drawback is the swing out screen... I do like that I can close the screen for protection, and that I can use the swing for better portrait orientation shots (trying REALLY hard to find what's good about it). But having the LCD off to the side will be a struggle to get used to, really prefer the a77-99 multi-angle screen, not to mention the really nice version on the Panasonic GH6. Truth be told, I still use the EVF for the vast majority of my shots, so I'm hoping getting used to the new screen won't be a hard as I imagine. Wait and see....

That's the single drawback compared to numerous advantages for my decision on the a7IV as my, very soon, next camera. Hope that helps.

That's not so with the a9.


That i do miss on the a7c.
Another thing, the screenÖ I really dislike the fully articulating screen on the a7c, I canít understand how anyone think thatís a good solution to double the footprint and look on the side of the camera instead of the line of sight!
Sony had an excellent solution on the a77 and a99 why not se that?
That is also what I dislike on my Canon R and G1x. You get used to it, but still, it is suboptimal.

Aha, good to know that I can go down to f/11 on my A7r4 - I did not know that.

re. question: I think the A7iv is probably the best choice. 33mp is not that much smaller then 42mp. AF is better then the A7r4 and the A9 is basically a niche camera - you 3-year old is an Olympic athlete?

I like the IQ of my A7r4, but I do not need 61mp. I doubt you do. Storage is cheap, to me it was not be a deciding factor.I choose it over the A7r3 because of the (much) better AF system and it was the newest back then.
The 24mp of the A9 could be limiting when you're used 42mp.

So, I think the A7iv is a Goldilocks and the one I would buy if I was buying right now.

Just my Ä0,02
