In my last post I discussed my recent purchase of the Lumix GH3 for shooting video. This will be its main purpose - in conjunction with my Lumix S5 - to supply video and photos for a Real Estate firm. But it will also act as a back-up of sorts, if anything should happen (please no, touch wood) to the S5 while on a shoot. So the IQ (image quality) needs to be 'good enough' to take over photo duty if required (again, please no....!).
Of course whenever you get any new gear, you need to test it out - right?! Nobody in their right mind would take a newly acquired piece of equipment and try it out for the first time on a shoot - least of all an actual paid gig! No - I thought not.
With this in mind, I loaded up my Lowepro backpack with my Lumix S5 and S 20-60mm f/3.5-5.6 attached, and the Lumix GH3 with the G 12-60mm f/3.5-5.6 Power OIS, and headed out the door this past weekend (as I write this).
It had been a while since I had been to Dorothy Falls at Kaniere, so that was my destination. I got up at stupid-o'clock on Saturday morning so I could get to the falls around dawn. Turned out this was a little too early, so I wandered down to Lake Kaniere to see if I could capture a few sunrise photos.
As you can see from the image on the right, reducing the exposure to retain highlight detail in the sky (very important with digital sensors) has meant that the landscape itself is underexposed. Looking at this image back home on the computer, I didn't hold out much hope of getting any detail or definition in the trees around the lake, especially since this is from a micro four thirds sensor.

Having owned, and used, 16MP Olympus micro four thirds cameras for many years, I shouldn't have been so pessimistic. I've written myself, on several occasions in this very blog, that the ability to extract information from the micro four thirds sensor is actually quite staggering. Micro four thirds sensors are capable of capturing excellent dynamic range - the GH3 itself is capable of around 12.5 stops of dynamic range.
In comparison, the S5's 24MP sensor is rated by DXO of 14.5 stops. Two stops is certainly significant, but this is a considerably newer - full frame - sensor. 12.5 stops on the GH3 is very, very respectable, and allows it to create images like the one above. What's more, the detail pulled out of the shadows is very clean and noise-free at the cameras native ISO of 200. A very good result indeed.

I would have liked to have spent a bit more time exploring Lake Kaniere, but I was being swarmed and eaten alive by the (in)famous west coast sand fly. They like the taste of me unfortunately, and as soon as I set up my tripod I was surrounded by the little biting monsters! I took this as my que to head back to Dorothy Falls where, given the slightly cooler temperatures of the surrounding bush, the sand flies were thankfully (mostly) absent.
This allowed me to take my time, and take two shots of the same subject - one with the GH3 and one with the S5 - for 'comparisons' sake.
I've already discussed the dynamic range capabilities of both cameras, and this can be seen in the 100% crops above. The S5 retains detail in even the brightest areas of the waterfall, whereas the GH3 doesn't quite manage it. On both exposures I was very careful not to 'clip' the highlights, but the GH3 sensor just isn't capable of retaining the extreme highlight detail. The full frame image is also very slightly 'crisper' than the micro four thirds one - again not surprising given the size and age advantage of the newer S5 full-frame sensor.
And yet, there's not a massive difference between the two - certainly not as much as some would have you believe there should be. I would take the S5's full-frame sensor over the GH3's micro four thirds - of course I would. But if you told me I had to use the 16MP GH3 from now on, it certainly wouldn't hold me back from making amazing images. And as a back-up to my S5, it'll do just fine.

Having just said that, I will admit to preferring to using the S5 over the GH3. For a start, the viewfinder on the GH3 leaves a lot to be desired. It's a little blurry around the edges for us glass-wearers, which makes composition a little tricky. Fortunately, when shooting video, I'll only be using the LCD screen which is perfectly fine to compose from. This was also the case for most of the morning while the GH3 was on a tripod. But take it off the tripod, use the viewfinder to compose and the picture taking experience is diminished somewhat.
I also prefer the weight, heft, and overall handling of the S5. The GH3 isn't bad in this respect, but the S5 is better (IMHO). The GH3 with battery grip weighs about the same as the S5 body. Add a lens to both of them and the weight is similar enough to not be a factor. But the S5 certainly feels better in my hand. That being said, the GH3 is probably the most comfortable micro four thirds camera I've ever used. Far better than the angular and retro inspired Olympus offerings like the OMD EM-5 and EM-1.

As someone who has had a lot of experience shooting micro four thirds - especially with Olympus - the Olympus vs Panasonic question is an interesting one. I can see why Olympus embraced their heritage with the retro OM look to their cameras, as much as I can see how it made sense for Panasonic to pursue a more traditional DSLR style to their cameras.
Personally, even though I like the look of the Olympus cameras, I do prefer the Panasonic's DSLR style ergonomics and handling. BUT.... I think that Olympus make the better cameras in terms of functions, engineering and technology. Especially when it comes to the Panasonic's Achilles heal - auto focus. Not that Panasonic's contrast-based autofocus is unusable. For stills photography it's actually very good. But video - well that's another story. Needless to say, I think I'll be using a lot of manual focusing with the GH3. And that's absolutely fine.

Is the 16MP Panasonic GH3 micro four thirds camera a twelve year old obsolete dinosaur that should be dismissed in 2024? No - of course not! In fact, it would be an amazing camera to give to someone who wants to learn photography and grow in their hobby. With great ergonomics, a very capable image sensor, and very good IQ - not to mention excellent video features (if you are happy to focus manually) - the GH3 was Panasonic's flagship camera when it was released in 2012. It was an amazing camera then, and it's a fantastic camera now. Not state-of-the-art, granted. But you're not paying state-of-the-art prices. And yet what you get for your money is above and beyond what you should expect at this price point. Cheap as chips, but oh-so capable. I reckon the GH3 will make a perfect video camera, and an ideal back-up for my S5.
