Choose 2 images and press C to compare them side by side, click on one to enlarge them both. Good for choosing the better/sharper one.

fantastic images, but in my opinion camera movement all the time is not necessary, if not disturbing.

NYCman530: I checked out the compare mode graph under conclusion and compared it to the Canon G5X and even though the G5X has a one inch sensor, it received a better low light rating due to the slow lens of the G1X lll. Had it been f1.8-4.0, that would have been a significant difference.

you have to set ISO value 4 times higher to compensate the 2 stops slower lens. So the ISO advantage has vanished.

They want to sell us this expensive model, and that is why Canon did not improve the G5X in terms of speed as they did with the near-identical G7X MARK II (that lacks a viewfinder).

Gil Aegerter: I've owned a couple of the old Nikkor 500mm mirror lenses -- bought the first one in 1986, the only new Nikkor I've ever owned. Image quality could be good in the right conditions, but the basic problem I found was one of steadiness. These lenses are very light for their focal length, and hence very susceptible to shake. I found I had to shoot from a very rigid tripod or put it on a monopod so I could act as an absorber. Maybe newer bodies with stabilization could solve that. https://www.flickr.com/photos/tags/nikkorcreflex500mm

"IBIS in a SLR doesn't stabilize the viewfinder" that's true, but the best stabilization of today's cameras is the combination of IBIS and in-lens-stabi. Look at Olympus and Panasonic. I know, they both have electronic viewfinders, but nevertheless they use in-lens stabilization and their systems could even benefit with a reflex viewfinder.

"newer bodies with stabilization"..sadly none of the Canon ones!

jst13: For mft to big..all benefits from Mft are gone , compared to APSC and FF lenses also expensive. Pro Bodys are now massive and lenses too...........and for the new mft price ranges..you can buy much better and less bulky systems..like Fuji or Canon M line and Sony
Jürgen

It reminds me a bit of the "Compact Cassette" audio recording system, once invented to have small, easy-to-use tape-recorders (mono, half the tape speed of the usual system). Audio quality was usable but not great. Later the system was pushed to hifi-stereo, big units, better sound quality, but still too small cassettes and short recording times, huge technical efforts for the changed aims. The disadvantages of the small system - just like mFt today. Nevertheless, I like my OM-D and rarely use my 5D any more.

nokinonacynos: This novelty will wear out in no time. In the era of high mp plus photobooks, mags and phone screens not getting any bigger, what practical use is there? Pixelpeepers would love it though.

IBIS first came from Minolta, as far as I know.

Yohan Pamudji: Since the EVF is OLED, that means it by definition isn't field-sequential, right? Sorry for the stupid question. I'm sensitive to the rainbow effect of field-sequential displays like previous Panasonic EVFs, so it would be great news to me if this one isn't.

I suppose the GH5 EVF is the same (a bit less magnified), and it's the best EVF I have seen so far. Of course not field-sequential but very clean and stable. For me personally, the EVF of the G9 would be the strongest argument to buy one.

Jan Chelminski: Imagine you are riding your nice motorcycle, having a nice ride, but constantly, people in cars keep yelling out of their windows “Hey, I got four wheels!” and “Hey look, I got 3 passengers!”…after awhile (if you happen to be one of those people that can play ‘mystery science 3000’ in your nightmares), you might start to think that everyone in a car is an idiot, right? Just sayin. You see, way back when, Olympus did the numbers. They know how to make world class optics, so when they looked at what would be required in terms of size, precision, complexity and the related costs of optics, to design lenses for 135mm digital cameras, they reached an inescapable conclusion: They will be too big and too expensive. So, 4/3 was born, which became m4/3. With m4/3, you can have the best quality optics, while still having size and cost under control. Personally, I am very happy and feel quite privileged to use a system as fine as m4/3. YMMV.

Best,
Jan

When 4/3 was born in 2003 I found it was a needless, expendable system. Same size as existing APS-C systems (Canon, Nikon, Pentax), but worse IQ. When becoming Micro 4/3 things changed and I am now very satisfied with my little Oly. I carry it everywhere. What really bothers me is the unability of the two big companies to make a fully compatible system. DFD-autofocus only with Pana lenses, different directions of turning the zoom ring with Pana- / Oly lenses, image stabilisation with sensor AND lens together only with lenses of the same manufacturer.... Acceptance of mFT would be better if everything would fit within the whole system.

justmeMN: The body of the Panasonic G9 is bigger than a Canon SL2 DSLR.

http://camerasize.com/compare/#725,715

for my hands a Panasonic G9 fits better than a Canon SL2 , no matter what sensor size is used. For my shoulders a bag with mFt lenses fits better than a bag with canon lenses.

The description of this dark center filter coming with this lens and the strange bokeh brought me to an experiment with a 45 years old Pentax Takumar 2/55 (unfortunately multi-coated already) on a MicroFourThirds camera - a round spot glued to the middle of a filter in front of the lens (wide open f/2).

The lense I was waiting for !

YES! At f/5,6 and 24mm it`s defintetly better than my Canon EF 24-105 L @22mp, I have that lens for ten years now, but the new version seems not better.

Mach Schnell: Aside from dynamic range, the only other substantial weak point of 10 year old cameras is the LCD screen on back. Monitor technology has improved a lot in the last 10 years.

That's correct, but you don't need the screen to take good photos. I seldom look at the screen immediately, even have disabled the immediate review.

I remember that time I was in a local professional camera store and saw a huge print with impressive sharpness and brilliance. I asked what camera this image was taken with and it was the G5! I had a 300D that time and later bought a G7 wich I replaced by a G9 because of RAW format. The viewfinder was the worst thing with those two cameras, decentered and not matching the final image. Problems with retracting the lens after switch off.
Phil Askeys samples have better detail than my G7 images! That's what I changed to a G9 for.
