My main camera and best I have had the pleasure of using is a RX10M4. I have had my eye on either an A9 or A7111. The Rx10M4 from what I understand is a m111 WITH AN a9 sensor. Auto focus is damn quick on both. So any advantage to stepping up or laterally with the change? I know the price difference is heafty but is it worth it? For what it matters I do have 2 of the RX10`s. So thoughts.....is the A9 or A7 that much better with IQ and such. Not ready to jump and I realize the sony lenses are pricey. This will be a slow move. Any thoughts. This would be my last camera. I shoot mainly wildlife. Just if you get a moment throw me a thought. Thank you

I love the a7III. I have one Tamron 28-75 2.8 and one Sony 70-300 G lens. That is it! I can cover 99% of what I want to shoot and get great IQ and sharpness. I guess I have just under $3,500 in the whole rig. Lots less than when I was all in on Nikon with over $15,000 in bodies and glass. I am down to shooting birds in the back yard, and going on cruises. Russia in 2 weeks. I might have wanted a good 15mm wide angle, but I could not make my mind up. I think this is also my last camera, as I am turning 80 and don't have the stamina to carry much or walk far. Good luck with your decision.

Yes both cameras are better than the RX10M4, worth the price, especially the A7III. But then be prepared to shell out a lot of money for the Sony lenses.

Mark is a great guy. Mainly shoots with Nikon but he owns some good gear. He is very helpful. When I have a tech question I email him and he is fast with his reply’s. I’d like to go on a photo shoot with him one day.

The difference between the RX10 and the a9/a7iii is the Bionx Processor.

This is an apples to oranges comparison. The biggest difference between the RX10iv and either the a7iii or a9 is the sensor size, as the RX10iv uses a smaller 1" sensor while the other two use a full frame sensor roughly three times the size. So no, they do not use the same sensor. They do share some sensor tech, however, making the RX10iv arguably the very best bridge camera made.

A larger sensor allows for better low light performance and generally better image quality with a higher signal to noise ration. Of course, a larger sensor also allows for larger prints or better quality when cropping for smaller prints or digital displays. It also requires use of larger lenses to allow a larger image to project on the larger sensor.

The RX10iv is an excellent camera, called the "Swiss army knife of cameras" by some. It does a bit of everything, and it does it very well. At times, I wish I had one instead of my collection of full frame bodies and glass. Perhaps one day I'll get one to supplement my gear. But as I like to do astro and landscapes and tend to crop rather heavily in post, I really need a full frame camera to work with.

If you are serious about moving into a full frame interchangeable lens camera (ILC) system, be sure you do it for the right reasons. Extra gear, weight, and cost... sensor cleaning... being sure you have the right lens with you for whatever you're shooting... so many inconveniences to consider whether it is worth it to you. At least gloat a little knowing you've already chosen what is a great camera for anyone, and more than enough for most people.

I have an A7S, A7R II, RX10 III & IV. I've been looking at the most recent Sony offerings and have decided the A7 III is the optimum choice.

As for image quality, a full frame will offer great image quality if one is into large prints/images; however, for 8x10 prints it is hard to tell the difference between one off a RX10 IV and an A7 III (with an excellent lens). With mediocre glass, the RX10 IV will be the winner.

If you shoot a lot of low light targets, the full frame A7 III will be the winner. Although I've shot targets at ISO 6400 with the RX10 III & IV and the results are reasonable; not great but reasonable.

Good luck in your decision process.

P.S.: I come from a Canon fanboy background and still use a lot of excellent Canon "L" glass with a Sigma MC-11 adapter on Sony bodies. I also use a suite of Minolta AF lenses with Sony's LA-EA4 adapter. Both options work well for me.

Your last camera..... In the long run I would stick with the RX10 because of size and weight but If this is truly the last camera and size, weigh and portability are not factors, then go to the A9. It is a tank and will last forever. I said the same thing when I got the Sony a99ii. But here I am now with the a99ii (my primary camera), a7s for night shots, a6000 for travel and also HX400v for airline travel. Kind of wish I had the RX10iv instead ofthe HX400v. Note: the a9 and a99ii have only a few differences. Both are Magnesium Pro cameras.

I have the original RX-10, and then I bought a Nex 7, APS-C sensor . I enjoyed both, but always found the glass on the RX-10 to be better than what I could find for the Nex-7. Then I traded up to the A7ii, and the 24-105 lens. Now I had a full frame sensor, and a lens that all consider excellent. The problem comes in what are you shooting? I had problems getting fast focusing on street shots (actually third world markets) with the A7ii. So I now have the RX-10 and a couple of Olympus bodies. The OMD E-M-5ii is the best travel camera, but the glass on the RX-10 is still the best. So the answer is "What are your requirements?" In my case the A9 would have been a better choice for me, but don't ever get rid of your RX-10!

Your assessment of your experience sounds spot on. I neglected to mention in my earlier reply that the RX10 series cameras use an outstanding Zeiss lens, with the last two iterations increasing the zoom to 25x (24-600mm equivalent). The a7ii you used for street is at best mediocre. It wasn't until Sony's 3rd-gen full frame mirrorless that focus speed/accuracy/tracking got good. I assure you, you put that Sony 24-105mm on an a7iii/a7Riii/a9 and it'll keep up for any street photography or fast action, even sports.

The A9 is the ultimate option ! ( and plenty of $$ to spend) The A99 II is next in line and selling at good discounts now !

IMO, the E-mount design suffers from being too SMALL ! (as it was originally intended for crop sensors) - and price of lenses being too HIGH.

I have a9 and a7m3 and I find that use the a7 the most as a shooting street, travel, and landscape. I do some sport mainly basketball and that is when I use the a9.

The sensor in the A9 is exclusive to the A9, not shared with any other Sony camera, and no other camera makers has this stacked sensor with integrated processor for electronic shooting at 20fps, with no rolling shutter ,no banding and no EVF blackouts. Plus able to make 60 exposure and 60 autofocus calculations per second. It is the ultimate mirrorless camera. Watch as Jason Lanier goes over the A9 vs A7RIII vs A7III.

Battle of the Full Frames! Sony A7iii vs. Sony A7Riii vs. Sony A9- which camera is best for YOU?
