thx1138: A better name for these lenses is Catastrophic. Works fine in a telescope where you don't care about bokeh, but for a telephoto, no thanks

If you want to do wildlife on the cheap get the Sigma 100-400 f/6.3, we don’t need mirror lenses

Och Elo: When I used to shoot with M43, the 2 cheaper lenses in this focal length (Panasonic 42.5 and Oly 45mm) were quite excellent imo. Indeed, I found most of the M43 "cheaper" lenses to be quite good values and good optically and I do think small inexpensive lenses is where the strength of this system lies.

Beware beware the Triplet Perar!

Daft Punk: I think the zero-black out of the Sony A9 is very special. A game changer. It has to be tried to be believed how liberating it is to shoot with zero VF blackout. Blew me away.

I think this achievement should be recognised.

Gear of the year to camera barely released and an update of an exisiting camera. Nothing ground breaking at all in it. A9 should have gotten the award, this award is farcical.

Will1355: Wow! Lightroom Classic CC is even slower after the update. This is really annoying. It is the slowest application on my imac. I have to start looking for a good alternative, I guess.

It's a total POS. Massive thread at Adobe forums about how crap LR classic runs on high end machines. It's good in a way since I'm now using C1 Pro 11 and DxO Photolab more and more and they are better and faster, much faster. All they need is DAM. Adobe are pitiful and it's good to see the pay to play approach has made things worse not better.

Triplet Perar: Let me explain the part people don't really "get" with these premium m4/3 lenses. An FF lens cannot keep look of its bokeh when stopped down to gain more workable DoF: you gain DoF, but kill the bokeh. And if you like bokeh, the DoF is so thin it is impossible to work with; or must move farther away, which, again, changes the composition and needed magnification.
Premium designs for m4/3 solve those problems, and such lenses deliver best of both worlds. (1) More DoF is better to avoid errors when shooting dynamically, with less focusing mistakes especially in portraiture. (2) Bokeh at f/1.2 is made NOT to match f/2.4 bokeh of a conventional aspherical design, which is very messy, but SURPASS it by far. The lens allows optical design (with more elements but with less thickness of glass) to render bokeh as if made with a much faster portrait lens of a classic design with fewer elements.
For those who really understand this, the m4/3 becomes best thing since sliced bread!

Well of course a 17mm lens can focus closer than a 35mm lens, it doesn't matter how small the sensor is behind it. This is a silly comparison, but why don't you check out the Tamron 35 f/1.8 SP

Show me a FF 35 f/1.4 whose bokeh @ f/2.4 is WORSE than the 17 f/1.2 wide open. Of course the bokeh is not as good as you stop down but that doesn't mean it's still not good.

As for the light gathering, the 4x larger sensor offsets the 2x higher ISO, so IQ will be very similar. There is nothing the 17 f/1.2 can offer other than smaller size and that's only if you compare 17 f/1.2 against 35 f/1.4, compare it to say a 35 f/2.0 or 35 f/2.8 and it's larger in nearly all cases.

Fred3542012: I own a Canon G5x and from my experience with it for more than 6 months I can definitely say that it's a very good camera . I had a Sony RX100 MK III for a few months and I sold it with a big loss (compare with the price I paid for it as a brand new ) because it was not a camera that I was comfortable shooting with it . It was too slippery , convoluted menue, and the View Finder was a mess to use quickly and comfortably. But,I highly respect other people opinion that believe it's a great camera because people are different and cameras are made for different people.
From comparing IQ of this new G1X with other 1" sensor,its IQ's better.
Would I upgrade to G1X MK III ? No sir , because I am comfortable with what I have and they both look the same from the outside and I have more zoom reach .
I believe , a camera is a tool for recording our experiences and memories and as long as " someone is comfortable and happy with a tool there is no need to change". Merry Christmas to you all.

One is developed by a photography company one is developed by a technology company that throws everything it can into as ridiculously small package as is physically possible with scant regard for whether it should. But hey the specs are awesome and that's all that matters to some, forget the actual shooting experience or end result.

kobakokh: to be honest i saw this video and i think Canon 6D2 is very bad camera for landscape photography, especially in that contrast scenes. Very small DR, you can see at this video very easy. If owner will use, for example Nikon D850 (or D810), Pentax K-1 (its even cheaper then this plastic Canon 6D2), he will understand what is a really good camera for landscape photography. Ooh, forgotten, also Sony 7R2 or 7R3 is also great camera for it. Also, much better to use some wide fix lenses, for example, Zeiss 25mm, Sigma 50mm Art, i mean the lenses with very low chromatic aberrations which is very important for post processing.

Yeah I think according to Sony fanboys and probably Rishi, the 6DII has 1-2EV of DR, impossible to take any good photos in any light.

Is this article saying the A7RIII doesn't offer a single AF point option or small cluster for tracking. I can't believe that at all, if true utterly retarded.

5D4 can hold it's own against both these two despite the nay sayers. Anybody that claims any DSLR or mirrorless is a dud these days has rocks in their heads.

xPhoenix: I'd seriously consider switching to mirrorless, as it does seem to be the way of the future, but I shoot a lot of wildlife, and a DSLR still seems the better choice for that.

Currently A9 users are stuck using a 100-400 + 2x TC, and a 400 f/2.8 is not what they need. When the A9 was released so should have a 500 and 600 f/4 as well as 300 and 400 f/2.8 and a 150-600. Not much use using adapted glass when you can't get the high fps and all the best features of the AF.

thx1138: I’ve been using my own in-built neural network to do such things for at least 20 years.

In the future I won’t have to leave the house, I’ll send out my sentient drone loaded with a 1GP camera and in-built 14-400 f/2.8 lens and let it take all the photos. It will get up at any time and go out in any weather to capture the sweet light. It’ll then upload the photos on the wing, to my AI run house and the images will appear on my 10K screen within seconds of capture. It’ll then post them to flickr using my name of course and people will ooh and aah at what an epically good photographer I am.

Do I take the red or the blue pill?

Veselin Gramatikov: 4/3 are no sense for stills front of current cheaper and better FF/APS-C bodies.
Sorry :)

What the hell is a jpg! Who shoots jpg's on these cameras. In RAW the 7DII is cleaner at ISO 6400, a rather ordinary 3.5 year old sensor. We have other people crapping on about G9 being better than D810 and D750, just hilarious. It's noticeably behind APS-C let alone FF.
