Lumix G9 or Sony A7 III?

I have a Nikon D3100 and I want to invest in a new camera. G9 and A73 seem to be two powerhouses but of course each is part of different leagues.

In my opinion, the difference between M43 and full-frame is rather technical and I believe it is possible to take pictures with both systems which can look identical to the bare eye.

The size and the weight don't matter to me and I actually like when the camera feels more sturdy, the G9 being more lightweight is not a big benefit to me.

Regarding the sensors, dynamic range looks fine to me on G9, but it does come short on high-ISO. Surely sensor-wise A73 is the way to go. Plus, the auto-focus is much better. In the end Sony has a better offer, if we consider only the body.

The reason I am inclined to buy G9 is the Leica 16-60 kit lens which must be much better than A73's 28-70 kit lens (please correct me if I'm wrong here). I want to start with the kit lens because they the most affordable and versatile and with time maybe buy a few more.

I am amateur and one of my reasons for this purchase is to get a camera with which I can learn photography and also use it for at least 5 years to come. I am also thinking of waiting to see what Nikon has to offer in terms of full-frame mirrorless, however I think this is just the beginning for them (*ahem Nikon 1), Sony and Panasonic seem to be more advances with mirrorless technology and Nikon and Canon have a bit of catch-up to do. So, I am not sure if it's worth the

The video is important to me and I think both G9 and A73 can deliver great results, even though Panasonic seems to be the one more "specialized" in the video domain.

The bottom line for me is that I want something versatile. I believe both cameras are good for any scenarios, except for G9 when shooting sports on a professional level. I believe I won't have to shoot sports any time soon, especially as a pro.

***

So, is it worth to buy G9 just for the 16-60 kit lens? I will only buy another lens after about 2 years.

Any advice would be of great value, thanks a lot for reading

When I was trying to decide between the two cameras, I went with Panasonic because I do video a lot more than photos. The G9 shoots 4K60p and the IBIS performs way better when walking and/or moving the camera. If you're doing mostly  photos, don't need 4K60p / better IBIS, and are okay with the lens of the Sony, it seems like the better choice.

The only other major advantage I see with the G9 is that the weather-sealing seems to be much more robust than Sony's.

while the G9 is at disadvantage w/ Hi ISO's and for shallow DoF*, it is much much better for Ergo's and UI!  Clearly superior stabilization.  It's biggest advantage is in the system of lenses available.  Many more options, esp in the category of small, sharp, fast, & affordable...  all at the same time!

* shallow depth of field is a "2-edged sword".  For most of my photography it is undesirable!

I have both these cameras and it's a tough decision. For low-light and higher dynamic range, the A73 outshines the G9. With that stated, here are the things I like about the G9 compared to the A73:

  • Ergonomics. The G9 has a much better grip than the A73 and it feels so much better in the hand.
  • Menu. Eventually you will get used to the A73's menu system but the G9 is much more intuitive.
  • Video. More options on the G9 and the color right out of the camera is better than the A73. The A73 has slog which does help with highlight-rolloff, but I always feel like I'm tweaking skin tones on it to look more "Canon-like" whereas the G9's color science right out of the camera is excellent.
  • Autofocus. The G9 is pretty good for stills and video, but the A73 is better...but not by that much.
  • Cost of lenses. Sony glass is ridiculously expensive compared to equivalent M43 glass. You do however have to pay attention to lower f-numbers to compensate for depth-of-field compared to FF cameras.
  • Weight of lenses. Oh, how I enjoy the light-weight lenses of M43 cameras!
  • Already mentioned, but worth repeating...IBIS is spectacular on the G9. Beats the A73 handily.

The bottom line is, I use the A73 for wide-angle shots and low-light astrophotography. For about everything else, I enjoy using the G9.

Re: Lumix G9 or Sony A7 III?

here was my thought when i brought both 3 months ago;

Well thanks everyone for your comments, even the negative ones, i notice whatever someone post you will always have someone who trolls the forms with nothing else to do but push negative comments, i must pray for them and even their negativity will help me to grow , anyway I have tried both cameras and from my initial observation (please understand i said initial from an amateur enthusiast photographer) and my limited usage (i tried to keep it to a low click count) also i am not here to bash any product but to help others who are on the fence like me determine what camera they want to buy

-the build quality of the a7iii was not bad very solid like most sony products, but to me the G9 felt much much better especially with the grip

-to me one of the biggest problemswith the a7iii was the menu system, this may be okay to some but moving the little wheel to different pages was a headache as i tried to maneuvered that little wheel around they need a complete touch screen

-the shutter sound of the a7iii was very distracting compared to G9 (maybe it's just me) i have gotten use to the sensitive shutter of G9 now i love it lol

-the pics out of the a7iii with the kit lens were excellent and full of detail, im sure they would be even better with better glass, the dept of field was great even at 3.5 it surprised me!

View: original size

-the view finder on the a7iii was okay but no were near as nice as the G9

-the feature set on the a7iii was very very limited compared to G9

-the stabilization on the a7iii was no were near that of the G9 you must buy a gimble for video work or your videos will be very very shaky, also the cameras auto iso loved 12,800 for some reason (i know it can be adjusted) i guess just like the G9 loves 3200 lol. if Sony gets good stabilization it will be a true game changer

-the 4k video was about the same as the G9 but the a7iii had richer color and the pics clearly had more detail on a7iii and in video kept the highlights down very well much better than G9, also the charging port on the a7iii is cheap and the door part seems as if it will break over time

View: original size

In the end one reason i would get the a7iii is the dept of field a full frame camera offers, yes i can get close with G9 but in the end the G9 would cost me much more to achieve the dept of field than the a7iii (at least at this price point ), and in the end it's all about the pics, or is it? The a7iii menu and feature set is lacking, I have never enjoyed a camera like the G9 and the many features it offers, time-lapse, 80mp pics, stop motion, 4k 60fps, top lcd, even in camera raw conversation, tilt twist around screen. so this morning i have the a7iii boxed up and ready to go back. Thanks for listening i know most of you knew these things already but i got to see for myself.
 God bless

I agree with the comment about the depth of field being a double-edged sword.  A lot of us get into cameras partly because we love the shallow DoF look and the artistic control it affords, and then we go nuts with it.  Computer screens, tablets, and smartphones make this even worse, because the DoF needs to be even more shallow to be apparent on a smaller screen.

But it is a double-edged sword.  I've been doing a lot of family photography, and I often use the f/1.2 lenses for the purpose.  But I've been finding that when I view my photos large - either full-size on a 27" computer monitor, or when printed - that not everything that I wanted is in focus, and the out of focus areas look blurred to an unnecessary degree.

Granted, it's a matter of taste and with what you're trying to achieve.  The guys who want to blow away the background into two or three colors even if only one eye is in focus wouldn't be happy.

It also plays into ISO, though.  I can shoot indoors at f/1.2 with ISOs around 1600-3200 without a flash.  But on a "full frame" camera, f/1.2 would render an impractically thin depth of field.  So I'd need to close down the aperture, but then we're raising the ISOs... which may completely negate any high-ISO advantage that "full frame" has.

Long story short, depending on what types of photos and scenarios you're trying to take photos of, one system may be better than the other... but it also may not be for the reasons you thought it would be.

Re: Lumix G9 or Sony A7 III?

i have GH5 and a7iii and i love both cameras

a7iii is beast in low light autofocus tracking in video is great but lens sizes are big and expensive the 5 axis stabilization seems like its not even present compared with gh5 i can shoot video hand held

i honestly think they both take great pictures i cant decide one over the other and im sure G9 is a great camera too

To boil it all down

A7.3: for landscape (resolution, color depth, DT), portrait (shallow DOF), children (AF) and low light. To fully use the advantages, get 2-3 primes or the 4/24-105, not the 28-70.

G7 or GH5: for video (IBIS) and if you also want a lot of reach (up to 800mm equivalent with the 100-400). Also for better and smaller lenses: the PL 2,8-4/12-60 is superior to the 28-70 in every respect, but make sure you get a good sample.

Re: Lumix G9 or Sony A7 III?

Nobody can really answer that for you.

There are some very substantial (and obvious) differences between the two, and only you can tell which ones are more important to you.

For example, if you want/need 4K at 60p, the G9 is the obvious choice. If you regularly shoot at high ISO, the A7III is in a different world.

Of course there are so many other factors. The A7III will probably get you a better Continous AF-tracking experience, while the G9 will be snappier and more consistent for Single AF.

Then there’s the features. The G9 has high-res mode, 6K Photo mode at 30fps and 4K Photo mode at 60fps. These, and other features, can be very important for some people, or won’t matter at all for others.

IBIS is also much better on the G9, for stills but also for video.

Sony has a 1.5x magnification video mode (APSC mode) in full 4K resolution which I find it can be extremely useful. The G9 doesn’t.

Then of course there’s the lenses. Again only you know what you want in your lens line-up. There’s a big difference in size and price for some lenses, not so much for other lenses. For example, if you want telephoto lenses, all Sony’s options, while great, are huge and expensive. Same goes for ultra-wides.

Re: Lumix G9 or Sony A7 III?

Dear Pe tru,

firstly, if you just want to learn photography, your Nikon is a great camera for that.

So you actually want to do something else, it seems. You are at the cross road among a few "technologies".  so you really have to think what else is important for you first. FF vs crop sensor (directly proportional to low light capability, DR, and IQ). If you need fast focusing for birds etc, mirrorless are less capable than your Nikon and other DSLR. Mirrorless are fantastic for portrait and landscape.

Frankly, I think M4/3 will disappoint you somewhat, versus your Nikon, if you consider IQ and low light performance as important. But they have better range of lenses than Sony, much more.

Sony A7III is great for IQ and low light. But lenses are expensive and not many to choose from. If you don't intend to have many lenses, it's good enough.

I have a Canon 5DM4 and GX8, each system with about 6 lenses. Sony doesn't have the range of lenses I need (for  now).

Hope the above helps.

Re: Lumix G9 or Sony A7 III?

Hi guys, Im considering to get a new camera. previously I used olympus EM1 mark 2 which I love (great ibis, great battery, great egro) but I had to sold due to financial issue at that time.

Now I'm looking forward to get new camera. I love sony colour profile. Everytime I see youtube video shot by sony, I always like the colour tone.( Usually shot with slog then colour graded)

In terms of other pros and cons, I think this discussion has answered everything. The last question I have is whether lumix can get identical colour profile to sony?

Thank you

Re: Lumix G9 or Sony A7 III?

Well, I considered A7iii when I was in the market looking for a camera in 2018. I ended up buying G9 because of its rich features (for stills and video) and lower cost (for body and lenses). The extra money you would pay for A7 just doesn't justify what you get over G9.

Re: Lumix G9 or Sony A7 III?

I`m a G9 user, I was recently looking at moving up to FF. During lockdown I have like most people been taking shots local or of flowers in the garden using the Oly pro 40-150 and Pan/leica 12-60. When I look at my images of flowers and bees etc I really don`t think that the outlay for FF is going to be worth it for me. For distant stuff and wildlife I use the pana 100-400. When people talk about shallow DOF I find the 40-150 wide open to be superb.( did I mention the IBIS?)

Enjoy your choice

You need to find out what LUT was used for the S-log. Then find if the same LUT is available for V-log L (usually it would be if it's a common one). If so you can get a color profile that is largely identical. Panasonic has multiple cameras that support V-log L.

The G9 in this thread does support V-log L if you buy the DMW-SFU1 software key and can apply LUTs even in camera or to HDMI output using a vlt file.

Re: Lumix G9 or Sony A7 III?

I think it's worth noting that the a7iii is the entry level model of their full frame range and the G9 is Panasonics flagship M43 body. There's a difference in material quality and ergonomics that favours the g9. The a7iii is pretty full featured but they did cut some corners to get the price down (particularly with the evf). If you handle both you might find it difficult (like I did) to splash the extra cash down on an inferior body.

Hi It depends on what type of photography you do most.

for video the G9 has lots in its favor and also for stills, ibis is a major asset.

on Sony’s side the much advanced AF can be a major advantage as better dynamic range too..

if you shout sceneries or portraits you may prefer Sony over Panasonic.also the ability to track moving subjects more constantly and precisely can be an advantage to Sony.

g9 has the best ergonomics seen in years. It offers an excellent menu system and true touch LCD interaction.

the mft lens lineup has everything you need and even more and an excellent user base.

it’s your take.

Re: Lumix G9 or Sony A7 III?

I agree, I have both Sony, A7r for landscape using wide angle lenses & A7S for lowlight video and Astro photography but rest of the time Panasonic G9, including videos at 4K 10 bit through Atomos Ninja V. Sony A7r is Going very cheap at EBay, it is very capable camera for landscape and low light set up.

So, is it worth to buy G9 just for the 16-60 kit lens? I will only buy another lens after about 2 years.

Any advice would be of great value, thanks a lot for reading

There is a general consensus the Sony 'kit' lens isn't anything to brag about. Just going from reports so take that FWIW. There are however lots of good alternatives. Tamron makes a reportedly excellent 28-70 2.8 and several small f2.8 primes. Lots of 3rd party options with Sony and the selection appears to grow almost every day.

The PL 12-60 (12 not 16) is a bit of a mixed bag, but overall a very decent lens. If you like to shoot wide and plan to make big prints, the 12mm end will probably disappoint you. If you don't ever print big you may never notice the issues at 12mm. From 18mm up it is quite good. If you get the Pl 8-18 and pair it with the 12-60, using the 8-18 up to 18, then you have a very good 2 lens kit. I have both of them BTW.

The G9 is a good overall camera. The continuous AF is bad though. I hardly ever need to use it but my few attempts have revealed it to be almost useless.

In todays market I'd take a good hard look at both Canon and Nikon FF gear. I don't have any Nikon gear, but the Z5 looks like an excellent affordable FF camera.

I'll throw one other option out there, the Canon RP. I recently got one with the very light 24-105 f4-7.1 kit lens. Now don't let the aperture scare you. This lens is like a m43 12-52.5 f2-3.5 so it is actually faster than the Pl 12-60. If you are unsure of why, I can link you to an article explaining this. The lens is similar to the PL 12-60 in that the wide end suffers a bit due to distortion correction (common to a lot of mirrorless standard zooms).

Camera is small, light, but operates very comfortably. Large hands might find it a bit small. Canons RF glass is superb when you want to add on later and you can adapt any EF lens ever made opening up a huge world of excellent affordable glass. The AF on the Canon is vastly superior to the G9 as is the high ISO performance.

For something a bit bigger, the Canon R is similar size to the G9 and has an even better sensor than the RP. Great VF also as the G9 VF has real bad pincushion distortion. Both RP & R lack IBIS, but if using zooms this is a non-issue as all have IS and some primes do also. I have an R also and find it a superior camera for my needs to my G9 overall.

Just a couple of other options to consider from the point of view of a long time m43 user.

The G9 w PL 12-60 is certainly nice. I have this exact combo and especially with the PL 8-18 added it is a very capable setup. A few years ago it would be a top choice. Still a very good camera/lens, but a tougher choice now. Look hard at other alternatives and consider where you think the camera market will be in 5 years or so (i.e. not all brands/formats are going to survive).

Just want to add I do little to no video so I'm commenting on stills performance here.

Re: Lumix G9 or Sony A7 III?

I had a G9 ( it was an impulsive purchase as I had GH5 as well) and ended up selling it.

I used it for 8 months and I loved it, it has much better handling than GH5 ( at least for me) I loved its ergonomics . I sold it instead of my GH5 since GH5 has better video features and wanted to keep a MFT for video works I am planning to do. I will keep my GH5 and Pen EPL9)  Oly 12-40 Pro,14-42 , fantastic plastic 40-150, 42.5 f 1.8 and Pany 25 1.7 for video work and portability (EPL9 fits in my pocket).

I think GH5 and G9 are both fantastic cameras, especially if you consider their cost. They answer my rookie needs more than enough. But eventually I will get a FF camera, likely it will be Nikon Z or Canon R when they become more affordable.

In the end only thing I can advise you, try to buy your equipment when there is a good deal around. If you do that way, you will not lose too much money and can move from one to another.
