Exactly, and it's also priced be potentially attractive as an alternative to the A7S III and SH1. It's pretty obvious with the releases of the R5 and R6 and now this that Canon are going all out to defend their low/mid pro-level market against further inroads from Sony. It's going to be an interesting battle to watch...

DFD generally works better at higher frame rates (so 50p is better than 25p), also sometimes choosing a slightly faster shutter speed can help since there is less motion blur e.g. try 50p with a 1/120 shutter instead of 1/100.

Yes, I know - I have my G9 setup like that, I use it a lot for wildlife video 🙂

I've never used a GH5 so I can't compare them as a user of both (I own a G9). The G9 is supposed to have better C-AF, has better IBIS/EIS, and it's cheaper. It does not support the XLR audio adaptor, does not have any 'All-I' codec modes (there is nothing above 150 Mbps), maximum record time is 30 minutes (10 minutes for 4k50p/4k60p) and doesn't have waveform monitors/vectorscopes/shutter angle control (and some other 'professional' video-specific features that are on the GH5). It gained a range of long-GOP 10 bit, HEVC and high-bitrate 1080p codec modes in the recent firmware updates. If you need to check for a specific feature etc., it's probably best to download the User Guide and have a read. Effectively, it has a more stills/less video orientated feature set, but with the same basic video capture quality as the GH5 i.e. excellent 1080p and no-crop 4k up to 60p.

If you have 'Extended Tele Conversion' enabled all the time, then changing the 'Picture Size' should do that (and 'Picture Size' can be mapped to a function button, as far as I can tell from the user guide). I don't own an S5, I'm just a long-term Panasonic m43 user.

It looks like it's the same as on the m43 cameras - for stills, set the 'Picture Size' to be less than full resolution i.e. M or S, then enable 'Extended Tele Conversion' (which crops into the sensor to give you a 1:1 pixel mapped image of that resolution). So picture size 'M' gives a 1.4x zoom/crop, 'S' is a 2.0x zoom/crop (with FF lenses) when 'Extended Tele Conversion' is enabled.

I've noticed that too - I bought my G9 about 18 months ago in the UK (new but cheaper than used at the time, due to very generous cashback offer and v.good price from dealer), and used prices have been steady or slowly edging up since then. I suspect due to new camera sales being well down (so fewer trade-ins/private 'upgrade' selling) there is just less used product around to buy which is pushing prices up. It's noticeable that some of the big dealers in the UK have been actively advertising to buy used equipment during the summer, including some selective cash buying offers where normally they would only take trade-ins. I suspect that used prices on the G9 will only drop substantially when it gets replaced by a new model, but I don't see any sign of that happening any time soon (and it's already a very feature-packed, high performance 'hybrid' m43 camera anyway).

I'd agree - if you want to stay with m43, the G9 is the way to go, it's a great hybrid stills/video camera with superb quality 1080p and no-sensor-crop 4k up to 60p, plus outstanding IBIS/EIS.

That's very low bitrate for 4k (only about 10 Mbit/s) - 4k25p files from the camera are about 100 Mbit/s for the EM10 and G80, so 22 minutes would be about 16 GB.

Correct. If you are in 'creative video' mode (the 'movie camera' icon on the mode dial) the LCD/EVF screen will show you the correct 'field of view' (FOV) for the movie setting in use (1080p or 4k) all the time. If it's in any other mode it will normally show the 'photo' FOV, then change to the correct 'video' FOV when you hit the video record button.

I agree with Kye that top-quality 1080p (e.g. GH5/G9 level) isn't very far below 4k quality, particularly if your final output is heading for YouTube etc., and it is a lot faster to work with 1080p when editing. But the quality difference is more noticeable with a lot of cameras due to lower-quality down-sampling/scaling from the full sensor area to 1080p. The GH5 & G9 have the processing capability to do it properly.

Yes, absolutely - I've been using them for a while, at up to 4k60p (150Mbps) in a Panasonic G9 (and other Panasonic and Olympus cameras). I normally use SanDisk 'Extreme Plus' V30-rated micro-SD cards, but you can sometimes get the faster 'Extreme Pro' version for not much more money. I shoot a mixture of 1080p and 4k. Using 4k allows for re-framing in post while retaining enough quality for good 1080p output. I'd also seriously consider a used Panasonic G80/G85 if you are thinking about a used EM-10 III - below the 'GH' level cameras, it's probably one of the best all-round cameras Panasonic have produced. Only real downsides are the crop in 4k and noisy audio from the internal microphones (but it has a mic socket so that's easily solved).

...also the G9 is not compatible with the DMW-XLR1 XLR adaptor unit.

The G9 has no 'All-I' compression modes (in fact nothing above 150 Mbps) but it did gain various 10-bit and 4:2:2 modes in the 2.0 firmware update. It might be that the GH5 IBIS sensor movement isn't accurate/repeatable enough to do a good 'high res photo' mode - or it's just market segmentation. If you look closely at the recent firmware updates for the GH5, GH5s and G9, a few changes have been only for the GH5s and G9 (the two more recent cameras) so I assume they have different (probably faster/more powerful) processing electronics than the GH5. As I don't own a GH5 I can't compare it against the G9, but I don't think you would be disappointed with the G9 - it's in a different league to the G85, GX85 and earlier cameras....

The EM-1 II has a 20MP sensor, no-crop (full sensor width) 4k video, plus phase-detect autofocus, weather sealing, mic and headphone jacks, bigger battery, better IBIS etc. etc. (it's a professional-level stills camera with very decent video and excellent build quality, basically). But it's bigger, heavier and somewhat more expensive than the E-M10 III (in the UK at the moment a used EM-1 II is about twice the price of a new E-M10 III) I seriously thought about buying a new E-M10 III a few months ago, but decided to spend the extra money and get a used EM-1 II instead as I wanted the extra features/weather sealing/build quality.

It's 8-bit

What's the problem with H.265/HEVC licensing - it's handled by MPEG-LA in the same way as MPEG-2 & H.264 as far as I know (and it's quite cheap - free up to 100,000 units per year, $0.20 per unit over that - see https://www.mpegla.com/wp-content/uploads/HEVCweb.pdf )

Minimising the cost of media storage and distribution (bandwidth cost) is what has always driven the development of data compression. It is the reason that broadcast TV originally used interlaced image scanning (it halves the transmission bandwidth compared to using 'progressive' frames at the same picture update rate).

What is your budget? You seem to be looking for the perfect camera but that doesn't exist, so you have to compromise to get as many of the features you would like and put up with things you don't like (especially if the budget is fairly limited and you want it small and light). I'd prefer the G9 to be smaller and lighter, but I put up with that to get the features I want (like excellent IBIS and 4k50p) because they are important to me. If I want to take out a smaller, lighter camera I'll take my GX80 instead and put up with 4k25p, worse autofocus, worse IBIS and shorter battery life in exchange. It's choices and compromises...like life generally...

LX100 isn't a M4/3 camera - it has a 16MP M4/3 sensor, but it doesn't use the whole area (it uses slightly different parts of it depending on the aspect ratio you select). That's why it's a maximum of 12.7MP stills. The lens needs to cover a smaller sensor area, so can be more compact. I think it relies very heavily on electronic correction of the lens distortions, as a trade-off for the small size - even so there is some barrel distortion visible at the wide end, and it's prone to flare sometimes.

I own both of those. LX100 is a great stills camera, and the on-board audio is much better than the GX80. Stabliisation is 'OK' but nowhere near as good as the GX80. Lens is great, although avoid zooming it during video shooting - it tends to look a bit jerky and 'flickery'. No tilting or touch screen, no in-camera charging. The GX80 is a better video camera - better stabilisation, better 1080p, easier to use as a hybrid i.e. switch instantly between stills and video. Tilting touch screen. Has in-camera charging. Poor sounding on-board audio (and there is no mic socket). Viewfinders are about the same on both. Batteries are the same type on both, and battery life (shooting video) isn't brilliant on either, but decent third-party batteries are cheap (as are USB chargers for them) so just carry a few spare batteries with you. I'd go for the GX80 with the 12-32mm pancake, and add the cheap/light/small 25mm F1.7 prime for low light etc. If you want a 'travel zoom' then get the 14-140mm F3.5-5.6 - it makes a nice 'super-zoom' combo while still being pretty small overall. All of those lenses are cheap used, and the two zooms support dual-IS.

I agree completely - it's hard to believe the G100 has been 'designed' by the same product planning team that bought us a succession of ever improving G, GH and GX series cameras - have all the good people departed, or are they being over-ruled by higher-up management? It just looks like a hurriedly-put-together response to the ZV-1 (Panasonic having got wind of what Sony was planning).
