About me:

Former military, medical and industrial photographer doing mostly technical and not very creative photography. (about 13 years) Most recently a fraud and compliance manager for a global corporation, including 11+ years in the customer support industry (internationally). Officially retired and will be relocating to the Philippines by end of summer 2015. Lived and worked there before so know what I'm getting into and relish the challenge of photographing as many of the 7,641 islands as time allows documenting the people, places and beauty of that nation.

dlg521: Mine arrives tomorrow from Verizon. Looking forward to testing it out in the real world. I've been VERY happy with my original Pixel XL so this will be a big improvement.

Cool. Let us know what you think after you have been able to put it through its paces.

This is interesting new tech. It would seem logical that to do this the sensor must have extremely fast read-out speeds and a lot of processing power in the camera phone. What works for a small sensor today, may someday scale up to larger sensors (See Pentax K1-II). The limits today are more along the lines of sensor read-out speeds and the image processing requirements. Larger the sensor and higher the sensor resolution, the more processing power needed. It will be interesting how this will work out. I suspect it will be a few ore years before the technology will fully scale up to larger sensors. Still I think it will be interesting to watch how this develops over the next few years. Google likely sees this as a path to higher resolution camera phones without creating bigger, thicker phones needed for longer focal lengths. It will be interesting to watch see which approaches will dominate in a couple more years.

Roland Karlsson: This technique is ages old. Used e.g. by PhotoAcute. It is also used in Pentax K-1 II. They call it dynamic pixel shift.

Photo acute was a computer based software solution. It required a series of photos to be taken quickly, hand held, and then those could be composited on a computer to increase resolution. The Pentax K1-II uses two approaches towards increased resolution or acuity. The sensor shift (tripod required) shifts the sensor 1 full pixel for each shot. This eliminates the bayer effect as each pixel then has full RGB information. Their hand held approach is similar but instead of shifting the sensor it uses natural hand motion to do the shift, but currently is not as good as Sensor shift. That Google is bringing this tech to small camera sensor is interesting. But to scale it to larger sensors is much more difficult. The limitation is sensor read-out speeds and computation requirements which are very high. I suspect Olympus may be working along similar lines, but there are technical limits. Still this is a step in a good direction that should someday scale to larger sensors.

It's about time. Now how about they don't strip any MetaData or give the photographer the choice on what info they want to show.

David 247: Fascinating. I am committed to M43 and low weight on my total camera bag, body and lenses. Still I find this fascinating. I spent most of my professional life (a few decades back) shooting with Medium format. On rare occasion I still get an itch for a high res sensor camera just for landscapes and Historical architecture and think about getting a medium format. Then of course I remember my bad knees and age and am thankful for M43. Still, that S1R with maybe a high quality FF zoom equivalent to the just announced 10-25 M43 zoom. 47mp sensor with 150mp pixel shift? Tempting, tempting... Likely though that my pocket book, back and knees will say no. Anxious to see what Oly will bring us with the new year. I do think the FF will appeal to journalists, wildlife, research, science and military photogs. You know the ones who will walk into hell to get the right shot. Ruggedness seems to be at the core of its design.

No firm prices have been mentioned. Some early estimates were $3,000 for the S1. and $4,000 for the S1R. But I wouldn't rely on those. Availability has varied from Early 2019 to March 2019. I wouldn't expect to have anything more firm then that until after the New Year. I think Panasonic mentioned Early 2019, but that could mean anytime by end of March.

I shoot with a variety of lenses as well depending on the subject, camera at hand and environment. But you are right that no matter the lens or camera, you want to avoid distortion if possible.

Never said anything about needing zooms. I specified one potentially very versatile, fast and hopefully high quality zoom lens as a template for a FF version of the same. But you are right one could use a collection of small primes as well. It is up to the photographer to decide what works best for them. Typically for landscapes and historical (detailed) architecture I shoot with wide or normal lenses. Very occasionally a longer focal length if I want to isolate particular details. There are always options and every photographer chooses the options that works best for them.

zakaria: Why not putting Panasonic instead of Lumix!
Panasonic is more famous worldwide!

Lumix. derived from the words Luminous, luminosity, etc. meaning light. Photography derived from the greek meaning to draw with light. (Greek roots φωτός (phōtos), genitive of φῶς (phōs), "light" and γραφή (graphé) "representation by means of lines" or "drawing", together meaning "drawing with light".) So it is a brand name intended to focus on the nature and practice of capturing light to form images. I rather like the name Lumix for the camera products. Panasonic is the corporate name that encompasses hundreds if not thousands of different products and is not specific to just cameras or photography.

MILC man You should ask yourself why you are here trying to convince everyone that they are wrong, Panasonic is wrong , everyone is wrong except you. Obviously you want a camera with Phase detect. Go buy one. Enjoy life and have fun. Why are you fixated on what Panasonic has or doesn't have? They are still working to what refine what they believe will be a good alternate technology. But you without any evidence claim that a camera you haven't seen or touched or used can't do what you need. So go get what you need. Let others use what they need. There are many different tools because there are many types of jobs and many ways of shooting. Variety is good. Go get the you need. Let other make their own choices. If you want a Sony, or a canon or for MFT an olympus go get one. Then get away from the forums and go take some wonderful photos. Enjoy your life. Let. others enjoy theirs.

zakaria: Cellphones eating the small sensors cameras and threatening the MFT. No one knows what tomorrow cellphones will be.so going to big sensors is the way to be more safely whereas no challenger to physics rules.

You know I do use my camera phone to take photos when I don't have good gear with me. Have a few advanced apps that can take some wonderful shots... sometimes. Keeper rate of photos on my cellphone ... less then 10% because I don't hang on to the garbage. Keeper rate on my M43. Usable 90%. Keeper rate: 60-70% and that is after I have spent a lot of time looking through to be sure I keep only the very best. Camera phones are good properly used and there are some photographers who make a living with their camera phones. Not many, but some. But it is their skill and luck of being in the right place at the right time that allows them to do that. The rest is creative skill . You won't see them doing selfies or grinning crowd shots or quickie snap shots of tourist sites. They use cell phones with higher res cameras and apps that allow them to correct, modify and perfect their images. They have real skill, and they source their images to places that don't require hi-rez.

daellis: Physics are physics--full frame cameras are amazing and these Panys look like no exceptions. But they come at a cost for many photographers. All you have to pull a DSLR to your face (or Sony A7 for that matter) and your subjects either scatter or chase you away. No one likes carrying 40 lbs around, no matter what label is on the camera or how fast the lens is. Finally, just how many "pros" are there to subsidize $2000+ cameras and $1,500 lens? A poverty of riches, methinks--will be interesting to see who and what shakes out.

hikerdoc. I have seen lots of professionals using Panasonics. Most of them are video pros, with lots of gear of all types, but a good number are also primarily still photographers. Now yes that are other pros that use other cameras, simply because there are so many other cameras. Would you even recognize a professional if you saw one? Those who do events stand out of course. Around the world many of them have gone to M43 or even APSC. But what about all the documentary, wildlife, journalists, etc. The ones who don't stand out, who are not seen, the ones who travel to wild lands and strange places? In fact one of the driving points for M43 is the camera size and weight for those who have to travel. Weight and size limits for aircraft carry ons are much more limited before. M43 are very popular because their kits can stay under the limits. . Panasonic and Olympus are very common. Maybe you only notice the bigger cameras.

MILC man. Doesn't matter that there is no DFD FF lens available now. Panasonic has that covered already. It will still focus with any lens, just a little slower I have already stated that DFD is not a limitation for me. But then again I grew up old school in photography before automation and know how to overcome problems. I am generally not a sports or action photographer nor do I do a lot of video and especially not video requiring follow focus. If I have to, I can shoot sports and action with a manual focus lens. I know the basics of how to do follow focus film video with a hand crank. I use my equipment to the max of it's ability. But I am prepared for what happens and know how to work around problems. I pick my gear for the work I am most accustomed to do, but never let it limit me -- I AM A PHOTOGRAPHER -- The responsibility for a photo is mine, not my gear. Clearly The Panasonic S series is not for you. Find what is. -- DFD is not a fail, it is just different

mgblack74: The Panasonic 50 1.4, 24-105, 70-200 look decidedly like Sigma lenses with new skin. Which is fine. And it explains how they can pump out so many lenses by next year.

NZ Scott: Never had any problems with any of my Leica branded Panasonic lenses. Maybe I am just lucky, but that is not my experience. However with any mass produced lenses there may be a few bad ones. Though in my personal experience, any bad lenses I have had from any manufacturer were replaced, and every bad one had either been a demo lens or a returned lens that was resold as new. So no telling how much of the problem was manufacturer error prior demo/owner abuse. Guess I have been fortunate with my Leica branded lens experiences.

Admittedly Cell phones are replacing the small pocket cameras of old but pose no threat to M43 or any interchangeable lens system.

KonstantinosK: With all the FF MILC craze I feel a bit it's a nice time to have a good DSLR FF in some good price. Pentax K1 original comes to mind.

Would be nice if Pentax created a FF mirrorless but kept their other core features, like IBIS, pixel-shift, GPS, Astro-trace, legendary ruggedness, etc.

Strange. I have been using Panasonic’s DFD for a long time and it has never failed me. Then again I entered photography at a time before autofocus oor auto anything for that matter existed. Maybe my technique, working process and attitude is just different.

LeDatas: The design of the body feels brutalist and blocky, all the way down to the chosen font. I hope they refine it before release.

Otherwise, I'm sure it'll be a great camera.

With a 5-6 month lead before final details are set and construction begins, there are likely to be many refinements. A lot of prototypes will be "smoothed out" before production. One of the advantages of advance notice this far ahead is that they can receive feedback from the public before the final design goes into production. So in a way it is a form of market research. If you don't like the design drop Panasonic a note and state specifically what you don't like. It will be considered with all the other feedback they receive. If you and one hundred other people respond with similar opinions but only 50 others approve of the design, they may be inclined to smooth out the edges some. It's like so many cars these days where I see designs I consider down-right ugly, but most other people see them as bold and aggressive. The ones most likely to buy the product are the ones most likely to be listened to.

Keep in mind that Sigma is a lens foundry and produces lenses for many companies as well a having their own Sigma brand. Lenses for M43 and probably also for FF that are labeled Leica-xxxxxx are designed by or with Leica but actual construction could be by Panasonic or any lens foundry. So yes they could made by Sigma or any other lens foundry, but with a Leica-xxxxx name are designed by or in conjunction with Leica. Yet still built by Sigma without the Sigma name. (or any other contracted lens foundry). To keep costs down and profits up, hidden cooperative agreements among companies are common these days. Such agreements likely involve oversight by the companies involved. So theoretically, a lens designed by Leica, with the Leica name, for Panasonic but actually constructed by Sigma (or someone else) will involve all three companies having Quality Control input throughout the process. It's like automobiles today. Most parts are actually outsourced to unnamed companies.

On article DPReview TV: Fujifilm GFX 50R first look (119 comments in total)

I see it as a good entry level Medium format for people who would like to give that a try. I also see it as a good medium format travel camera for landscapes and architecture. Compromises with an entry level price (for MF) and many people might find a 45-50 mp FF sensor to be nearly as good. Spent most of my 12. years professional career shooting with Medium Format film. As a Navy photographer our primary camera was the 6X7 Koni-Rapid Omegas. Compared to the old film Medium format cameras, this new Fuji looks like a dream of a Field camera.

Probably won't buy it. As a casual travel/historical architecture/landscape photographer these days, I'm keeping my eye on the Development of the Panasonic S1R which would provide a better size and weight solution for a old photographer with bad knees. Still though, I think it might be a good entry level for anyone wanting to get into Medium format digital.
