He never bothered to upgrade his 5D Mark III to a Mark IV.

Does it stay at 2.8 at 35mm?

OhWeh: The same price as the Leica M10, but so much more camera for the money. More IQ, AF, sealed, ....

Good luck getting lenses. Right now, their fastest lens is f/2.8 prime, which is somewhere around f/2.2-f/2.5 on full frame? Kinda not worth it.

Dr_Jon: Having shot a GH5 today I have some questions Panasonic haven't answered yet and perhaps you could help with:

(1) Will 480fps focusing be available on any existing lenses, especially the two f2.8 zooms and the 42.5mm lenses? (I'm assuming not.)

(2) Will Dual-IS2 be available on any existing lenses? (Again I'm assuming not.)

(3) What firmware are you using (I had v0.3 but I know v0.4x is out)?

(4) What do you think of the video AF, IMHO it was rubbish compared to a Canon M5 and not much advanced from my GH4 (and I was using a 480Hz lens, I think, the 12-60 f2.8-4)

Panasonic has 2 IS systems. Power O.I.S. and Mega O.I.S. Power O.I.S. is their latest standard included on some older lenses like the 42.5 f/1.2. All Power O.I.S. lenses should be Dual IS 2 compatible. Not sure about Mega O.I.S. And all lenses without any O.I.S. still get stabilization from IBIS on the GH5.

Just my assumption but 480Hz sampling done by their DFD autofocus system will benefit all autofocus lenses. It's able to sample where it wants to focus to at 480Hz, but the speed to refocus will depend on the lens. i'm guessing no lens will be doing it at 1/480s.

scifisteve: Personally, it is hard to get excited over a 4/3d's sensor camera. I do not care about all the bells and whistles. The bottom line is, the lenses let the camera down! If you decide to use a speed booster, you loose any advantage of auto-focusing, but you can get low light performance and wide angle lens options on that setup. Every native lens you put on this camera has a 2X multiplier!!! So--no wide lenses and poor low light performance !!! So, using this camera means that for the best results you will have to have total lighting control, or a very bright day. Then, you have to make do with many lenses with few wide angle options, and high F stops!!
But, if you are looking for wide angles and low light advantages, start with an APS-C or full frame camera, light and portable. Then build on that with an external recorder. Each system has its trade offs, that is true, but I am not a fan of small sensors. P.S. file size can be an issue. 60 to 100 Mb/sec easy, but 300 Mb/sec?

Maybe for the first year when I got my SLR, I took it everywhere. But these days, I find it a little over-the-top when I take my Canon SLR to casual outings. Friend's houses, cafes, trips to the mall. However, a GX85 with a f/1.4 prime lens seems keeps it fun and casual while not sacrificing anything when it comes to DOF or low light performance. The old adage, the best camera is the one that you have with you makes perfect sense. The Panasonic makes it outside the house more.

I think there are people who think they hit the lottery whenever something like this happens. But in the courtroom, your claim has to be justified. This did woman have a job that was going to pay her a 2 billion dollar salary over the course of 10 years, which she got fired from due to this Chipotle ad? No? Then the only loss is being an extra in a photo shoot...if there is such a thing. Maybe $25.

10 bits per color channel. 3 color channels, usually Y'CbCr. But RGB is a better way to visualize it. So 30 bits of chroma information for every 2 pixels of 4:2:2 video.

I finally upgraded my 20D to 80D this year. But people are always shocked when I tell them I used a 10 year old 8MP camera.

You can fix this with a cooling dongle. Only $70. Be brave.

The level of expertise is something you'd expect a wedding planner or a friend knowledgeable in weddings would say. But for an article for this scale, reach, and the tone they used to voice their opinions, it's an embarrassment of an article.

The Name is Bond: The crucial next step is a large aperture prime. For almost all.

Taking pics with the kit lens is going to disappoint, especially when you see your friends' iphone 7s fake-blur pics. Not everyone loves bokeh, but most do and expect it from pro pics whether they are conscious of it or not.

For an aps-c camera, the most practical lens to give serious satisfaction, exclusivity and fun is a 50mm f1.8. And not the Crappy Fifty (ie, Canon 50mm f1.8 II or III) but a modern lens design that is sharp and well corrected wide-open with soft bokeh. The kit lens can do everything else, but the 50mm is going to give the exclusivity and satisfaction, particularly for families.

I fully agree. You need gear that will produce images that's going to inspire and encourage you. It takes a lot of lot skill and knowledge to put meaning or a story behind a flat photo with no depth. However, a lens like a 35mm 1.4 (for a APS-C) that basically adds depth to any photo at any distance sometimes introduces context where there might be none will produce images that you want to give family and friends. Too many people give up without ever getting that kind of satisfaction just trying with a kit lens...which is capable, but never used to their maximum usefulness by someone just starting out. So it's better to not give up and cheat a little in the beginning so that you keep shooting.

Another thing I recommend is a flash unit. I highly recommend picking up a something like a YongNuo flash for $65. Just put it on full power, fire it at the ceiling, and it'll distinguish your photos from any picture that could be taken from a smartphone. And it'll teach you about light.

I would have voted for the GX85 if it was on the list. I have more capable cameras when it comes to dynamic range, noise performance, IQ, however, GX85 is the camera I have with me because of it's small unassuming size and discreetly fast and silent continuous shutter.
