Lumix G3 User Review by John Nicholson

The Panasonic Lumix G3 User Test

Handling and the user interface

The new G3 is a beautifully made camera, a fact that becomes evident the first time you handle it. However, it is also a rather small body where the decision has been made to replace many of the operational switches (including drive and focus modes) with Quick Menu and touch screen ‘virtual’ activators. In many ways this is a logical development, though it will initially ‘discomfort’ togs like me who have been shooting with traditional, physical control knobs and switches for many, many years.

In reality though it only takes a couple of days to get used to this change. Just as well, as on arrival late one Friday afternoon I discovered that the G3 had been supplied with only a short ‘Getting Started’ guide. The advanced manual now comes as a fully interactive PDF file, which is excellent; unfortunately it wasn’t in the box with the test camera. Chris and Steve quickly made it available to me after the weekend but in the meantime it was basically down to the G3’s user interface to teach me about itself and where I could find the settings I wanted to change. It did a very good job of doing so. The on-screen menu systems of these cameras continue to evolve thanks to the obvious effort that Panasonic are putting into their development. That on the G3 is fast, intuitive and highly customisable. You also have assignable function buttons that will help you to set up the camera to your own operational requirements.

These operational changes have made it possible to produce an advanced camera with high-def’ EVF that is significantly smaller (around 25%) than the preceding G1 & G2. The reduction in size will be seen as a bonus by many but for some of us, including me, I’m sorry to say it’s a bit of a problem when shooting hand-held and one which I failed to resolve during my six-and-a-half days with the camera.

The reason for this is basically that some controls, namely the D-Pad and control dial have been retained in much the same positions as found on the G1/G2 – but in a smaller area. I found that when shooting hand held using the EVF, particularly with a longer, heavier lens such as the 45-200mm, I was gripping the equally reduced finger grip on the front of the G3 quite hard. This had the effect of causing the heel of my thumb to put enough pressure on the D-Pad controls to accidentally activate them; usually at just the wrong moment when I was about to get that killer shot! I have to conclude that as it stands the G3 is better suited to photographers with smaller hands or for tripod mounted use, where this ceases to be a problem.

Fortunately, the positioning of the D-Pad proved to be my only major problem with the G3 though there are one or two other points that I’ll get out of the way now before concentrating on what’s great about this new G. First the battery. At an average capacity of only around 250 shots it’s too small for serious location shooting; during the test period I had to abort an excellent wild fowl shoot early because of this fact. Anyone buying the G3 is going to need at least one back-up battery if they intend to take their camera anywhere interesting. So my question to the good people at Panasonic is simply this: “If you really have to make the cells this small why not just put two in the box to start with?” Considering that there can be sourcing problems getting back-up batteries for new models wouldn’t it be a good thing to give users the power cells they really need as part of the initial purchase; even if that added a few pounds to the price?

My other ‘disappointment’ was to note the lack of an automatic EVF/LCD eye sensor and its replacement by a tiny manual switch as seen on the G10. Maybe it’s the way I shoot after a year with the G1, but I found myself pressing that little button many hundreds of times whilst taking over 800 shots during the test. I suspect that, given time, I’d have found a way to set the G3 up to avoid a lot of that manual switching but between learning the camera, getting the test shots and dodging the weather there simply wasn’t the opportunity to fully explore everything to the depth I’d have liked.

Lastly, for this part of the report, on the positive side of handling I can confirm that there’s now much less of a tendency to accidentally hit the lens release button. Also, despite the reduction in size and weight, this is still a solid little camera and surprisingly well balanced with lenses up to and including the 45-200mm. I actually used that combination a lot during the test because the ‘Light Speed AF’ enabled by the Venus Engine FHD processor in the G3 turbo-charges the focusing performance of this lens. The improvement is so great that I’d recommend people buying the camera to seriously consider going for the twin lens kit from the outset if they don’t already own the 45-200mm.

    I knew you, from your amazing photos and your technical advices about photography. Now I see your ability to writing technical reviews. Excellent job, comprehensible text!.

    Hi John, enjoyed the review, but felt it lacked some techie points i was interested in, like how the new touch screen menu’s navigated, i had a brief ten mins the other day in Jessops, and could not for the life of me find the new toy picture mode anywhere, would have liked to see some screens like pin point focus mode in action but guess you weren’t able to do this.

    As i said, enjoyed the review anyway mate, well done.

    John, many thanks for this real world, honest and comprehensive (given the time you’ve done it in!) review. Not only has it helped me in considering the G3 as a possible next purchase, but it has also encouraged me to improve my own photography and think more carefully about all aspects of shooting pictures. Your knowledge is infused with enthusiasm, a combination which is encouraging to all photographers whatever stage they’re at. Thanks.

    Thanks John, as a very new user of the G3 I found your review extremely helpful, particularly as you have been so much more systematic than I in your approach to the camera’s capabilities. Personally I find it more comfortable to support the camera with my left hand under the lens, leaving the right hand free to operate the controls. To begin with I found it too easy to touch the pad without intending to. I agree with your comment re a second battery. Shirley

    Thanks all 🙂

    Mark, you couldn’t find a ‘Toy’ mode because there isn’t one – you’re thinking of the new Olympus Pen models. My aim with the review was to look at the quality and capability advances the G3 represents both as an individual model and as an indicator of the future of the G System. I should think that full blow-by-blow operating instructions will soon be available for those that want them for study from the Panasonic main site in the form of the excellent PDF advanced manual for the G3.


  7. stanegate posted a comment on 24 June 2011 at 3:03 pm

    John, the manual comes on CD and is included in the new camera pack. I thought it too hefty an animal to print out, and much of it is basic common sense (how to attach camera strap!!) But it is possible to print out only those pages one needs and refer back to the CD when necessary. It would probably be useful for potential buyers to have access as a guide to the G3’s potential.

    I agree entirely Shirley,
    As mentioned in the review I didn’t have access to the full PDF manual at all for the first few days. Chris had to get permission for me to download it from a company server as at the moment, unlike those for older models, it’s not available from the main Panasonic Lumix site. I’m sure that situation will change in future as it would be a real resource for potential buyers as you say. In my own case it was the only way I discovered in the short time allowed that some features like DoF and Shutter Speed previews were still available with the G3 – if you knew where to look in the extensive menu system 🙂

    Upgraded my G1 to a G3 only two days ago, so far been very impressed with the new camera and still finding out the various features accessible via touch screen. Not yet able to register with Panasonic as it does not yet seem to be on their camera list to register!

  10. markansell posted a comment on 25 June 2011 at 12:13 pm

    Hi, john, the Toy mode i was looking for is in fact miniature mode, sorry i got the name wrong mate, here is a quote from the DPR preview.

    Naturally the GF3 also gets a couple of brand-new features all of its own. There’s an additional creative filter called ‘Miniature’, a variant on the currently-fashionable faux-tilt lens look that employs a touchscreen interface to allow the user an unusual amount of control over the final effect.

    I think it this case Mark, though it may sound like heresy, DPR may have got their facts in a twist. There’s no mention of such a mode in either the Basic or the (comprehensive) Advanced PDF manual for the G3 that I can find; and I also can’t find any mention of it in Panasonic’s online G3 blurb. I could be wrong though, have any actual purchasers discovered it? I’ll also take this opportunity to repeat my forum request that owners test their pop-up flash and let me know if they have an under-exposure problem with it.

    @ John

    Hi John, i just found this snippet from the Panny press release.

    Two modes – Photo Style and Creative Control – let users at any skill level get creative with their photos. With Creative Control, the user can choose the most-frequently-used color modes (Expressive, Retro, High Key, Sepia, High Dynamic and newly added Miniature Effect*4 mode) with easy access. In Miniature Effect mode, the peripheries are defocused while saturation and contrast is emphasized so the photos look like a diorama. The Photo Style mode revitalizes the conventional film mode with settings in Standard, Vivid, Natural, Monochrome, Scenery, Portrait presets while enabling finer adjustment of contrast, sharpness, saturation and noise reduction.

    The Creative Control options (Expressive, Retro, High Key, Sepia, High Dynamic) are in the G3 manual, but there’s no mention of any Miniature Effect in the version supplied to me. Perhaps someone from Panasonic would care to clarify this matter?

    Dave has just confirmed on the forum that the pop-up flash on his G3 seems fine exposure wise – so if there was in fact a problem with the review sample (it was probably just a negative exposure setting left by a previous reviewer) then it wasn’t representitive of the model as a whole.


  17. johnnewman posted a comment on 28 June 2011 at 4:42 pm

    Very good review John. I’ve not been around the forum for a while as I deserted MFT for a while as I felt the G1 had shortcomings for my particular needs at the time. However, I’ve been following various threads and am seriously thinking of returning to the Panasonic fold. I may still keep my Nikon for (say) sports shooting but am looking at the GH2 or the G3 for general work and your review was very helpful. I’m thinking that the GH2 might be the best bet (for me) and wonder if you had any thoughts between the 2 models. I do like dabbling in HDR so the GH2 seems to win on this with better bracketing, plus the multi aspect sensor but, apart from these 2 matters, do you consider either of the two a clear winner or not?

    Thanks for any comments

    I’ve not had the opportunity to test the GH2 myself John, so I can’t really make an informed comparison between it and the G3. The few months between the release of the two 16MP models is a very long time in terms of chip development for a company as expert in this area as Panasonic- so until someone can do a direct comparison there’s no way of being confident that the ‘pro’ GH2 actually takes better shots than the G3. However, as a demanding photographer it’s probably safe to say that you’ll find the handling better with the larger GH2 body – and we both know that’s a very important factor when shooting real world subjects.

    I suspect (though I’m not privy to any inside info on the matter) that it won’t be long before we see a GH3. In the meantime it’s worth quizzing existing GH2 owners in the forum (there are several experienced users now) about their thoughts on the camera’s actual performance. I certainly wouldn’t judge the GH2 by it’s mixed reception from magazine reviewers – who seem to either love or hate it in equal measure 🙂

    Hope that helps a bit,

    An excellent review John.

    I am pleased you discovered the touch screen focus so useful. I find it an asset on the G2, especially for macro shots. But it has to be on a tripod to make the best use of it.

    I am also pleased to see the High ISO shots are now worthy of comparison with the popular makes using larger sensors. A brilliant achievement by Panasonic. It makes me happy to have placed my money behind the Panasonic name. A brave act in a photo club club of nearly 100 members.

    Hi John
    Great review and sounds very promising especially as all reports seem to indicate the image qualities at Higher ISO are very good and more noise free.
    My question today concerns the lower ISO on this camera, is it as noise free from 200-400?
    The reason I ask this is because recently I read a couple of reviews with discussions over this, and the flow was about the lower ISO having more noise now, on the G3.
    In your opinion as some one who has tested this camera, do you think that noise at lower ISO has deteriorated?
    Would appreciate your feed back, so that I can consider upgrading my GF1, as the noise on the GF1 is very bad after 400 ISO.
    Thanks and best wishes

    Hi Neda,

    As I’ve pointed out in the main body of the report, noise is much improved over the first generation 12MP sensors at all available ISO settings from 160 to 6400. I found no evidence of increased noise at base or low ISO’s with the G3; just the opposite in fact. With RAWs it’s hard to spot any noise at all untill ISO400 and even then it’s sparodic, low level (some grain in darker areas) and easily treatable. By ISO1600 noise is present thoughout the RAW but is still fine grained and very manageable – though removing it will sacrifice some fine detail. At 3200 and 6400 you will see artifacting – but only on a level that’s pretty comparable with most larger camera sensors.

  22. dorudind posted a comment on 6 July 2011 at 8:05 pm

    Thanks John
    Sorry I had to ask you this again, and thank you for pointing it out again!

  23. nippa posted a comment on 7 July 2011 at 8:49 am

    I’ve only had the G3 for a couple of days and without doubt the smaller size takes some getting used to.
    In test reports I’d read that the jpeg performance was much better but I still find that faces seem too red and like many reviewers I have also found underexposure to be a problem. Noise is not an issue and ISO 800 is totally usable!

    The other great thing about the G3 is its focusing speed and this makes it far better with the telephoto lenses when taking action.
    However , unless you take action shots or low light I don’t see a compelling improvement over my G1 and GF1. The G1 is far nicer to handle.

    Hi Dennis,

    I’m not saying you’re wrong (different camera/conditions/subjects) but I’m sticking with what I said on page 5. I found auto-exposure to be ‘technically’ very accurate, which is all that I think you can expect from any camera without a little human intervention. Thanks to some hard work by Gordon I’ve only this morning had a chance to properly examine some auto-exposed GH2 RAWs (the other new model often accused by reviewers of having this supposed tendency) and again their histograms in Lightroom are bang on; far left to far right but without clipping either end of the range except in exceptional circumstances.

    With faces I photographed several subjects with the G3 and the only inaccurate colours I recorded were due to artificial light sources. The one on page 5, taken outside on a bright but cloudy day, seems if anything a little pale to me for preference – but it’s an accurate recording of the subject’s complexion. All the test shots were taken in Aperture Priority mode BTW (as that’s how I normally shoot), it’s possible that scene modes may alter the balance of pictures if employed.

    Just a note to say that I’ve now added a short video of clips taked with the G3 to the full resolution test shots hosted on my Flickr site: [url][/url]

    These were taken at 1080i but have been compiled in Premiere v9 and then saved out at 720p 25fps (Flickr’s maximum allowed quality). Re-rendering again by Flickr’s display engine hasn’t done a lot for their quality (I wouldn’t recommend viewing full screen) which was excellent straight out of the camera. Still, they do illustrate some of the points I made in the review.

    Thanks to the availability (at last) of ACR 6.5 and Lightroom 3.5 Release Candidates I’ll be adding ‘worked from the RAW’ versions of the G3 test shots (plus many more) to the Flickr full resolution set over the next few weeks.

    Early results are just as great as I had hoped they would be! 🙂

    Just purchased a G3 body to use the lenses I had for my 2 year old GF1. Moved onto the GF1 after finding SLR cameras too heavy at my advancing years after a life time in professional photography.
    The G3 technology is astounding print quality on 18″ x 12″ prints processed from raw files on a Fuji frontier machine and upsized in Genuine Fractals software match the quality and better than my old Hasselblad film camera.

    Having finished adding ‘developed from the RAW’ examples to the Review Set on Flickr I’ve now re-edited the captions of all the pictures in that full resolution set to reflect my conclusions (which remain very good) regarding the G3’s overall performance.

    The set continues to attract a very large number of visitors (the vast majority being other Flickr users, though there have also been many from this site); so I thought it was important to ‘flesh out’ the captions for those who may not read this full review.

    The URL remains:

    Job Done I think 🙂

    Good review; I too cannot find any miniature effect mode, find the flash weak? I have trouble under tungsten lighting with yellow shots (could just be me ?)

    Hi Ed,

    There is no minature mode on the G3 (as there’s no Pin-point AF on the GH2), these subtle additions tend to get added from model to model so the slightly later GF3 has it whereas the G3 doesn’t.

    Your not alone in noticing the bias in tungston shots (even with WB set to tungston rather than Automatic). It’s easily corrected in post if you shoot RAW, or you can get it right in camera by setting a custom White Balance temperature for the environment (not difficult – see Advanced manual).

    As for the pop-up flash I had some real problems, as noted in the review, but in general users semm to think it’s OK. In the end there’s only so much you can expect from a tiny built-in unit. For serious work I always use a Metz AF50.

    Additional (Oct 2011):

    Since writing this review I’ve had the opportunity to work with the GH2 body. It is equally capable of taking great pictures with very low noise and its video capabilities are second to none. So I can now say with confidence that both ’16MP’ models are capable of great performance, with the GH2 more suited to those of us with larger hands and a wish to explore creative video techniques.
