JosephScha: Let's see, 4K video (38## by 25##) is said to give an 8MP extracted still. This imples that 8K video (nearly 8### by 5###) should yield a 32MP extracted still. Considering that Panasonic has just one camera with a 20MP sensor, and that 4K video requires some pretty darn fast memory cards ... on the one hand I credit Panasonic for investing in something for several years in the future. On the other hand, I wonder if they realize it will be several years in the future before they can make this work?
Personally, I hope they can squish out a BSI sensor somewhere on their development path, it would be worth it if it can gain a stop of light gathering capability, I'll bet it can.

True. I know (from my company) how much it stinks to be behind, but sometimes a company does have to catch up, and then progress from there. I don't know if Panasonic sees BSI that way.

This challenge has very high quality entries. I didn't see any that I thought were off topic. And although I agree with placements in general, I have to say that unlike in some other challenges even the 97th - 100th entries were on topic and photographically just fine. Congratulations to everyone, therefore.

JmaverickPro: Anyone else look at the sample gallery?

https://light.co/gallery

Interesting technology for sure, but these samples look horrendous.

I figured there had to be a catch.

I just looked at the sample gallery. Most of the pictures look good. Exceptions: the bokeh on the chess pieces is disturbing. And the 2nd to last one, where the sunlight washes out the trees ... looks disappointing to me.

Don't know for sure, but I'll bet Japanese beetles. They LOVE rose leaves. I've seem them do more damage than these pictures show.

Mike FL: If G7 has an Recall down the road, how Panasonic handles it (as SN is off)?

I realize you wrote your question 2 months ago now, but I think it is now EXTREMELY unlikely that there will be a recall of the G7. One reason I think that is because I cannot remember any camera model that Panasonic has ever recalled. However, they have released firmware updates - on rare occasions.

In reply to:

JakeB: That is one ugly camera.

And yes, it does matter to me.

Those who have no eye for design have no business using cameras in the first place.

I think the G7KS is quite attractive (to me), more so than the all black model, and to my taste both are better looking - more like my idea of a camera - than the G6. I don't think it's just coincidence that Panasonic tried that rounded top and then went right back to more conventional shape.

On article Panasonic Lumix DMC-G7 Review (489 comments in total)

This is not specific to the G7. I just have to write: Reviews should no longer say "USB 2.0 (480Mb/s)" because as we all know, USB 2's protocol - having to turn the bus around to acknowledge each packet - significantly reduces the throughput you can achieve. 480Mb/s divided by 10 should be 48MB/s but even the very best card readers can't get that, the good ones can get half of that. It is time for cameras to implement USB 3.0 at 5Gb/s because the protocol supports streaming and has bidirectional communication (no "turn the bus around"). It is a windowed protocol: during streaming it does not wait for an ack for each packet, the acks can be behind by "window size" number of packets. Anyone remember XModem? Good ideas never die, they come back about a million times faster.

The 25mm f/1.4 lens shines - I think it's really something special.

creaDVty: Was the autofocus test done with a Panasonic lens? If so, how well can it focus with an Olympus lens?

I know m43 is a system, but why would one want Oly (unstabilized) lenses on a Panasonic body? Most Panasonic lenses are stabilized, except for short focal lengths.

re: "...the perception on the part of a lot of consumers that Sony is a consumer electronics company that also makes cameras. What do you need to do to change that perception?"

I think the answer is, you introduce innovative products like the a7R II with the world's largest BSI sensor. 4K video is new, but not a first. But 42MP full frame BSI, now that's going to do a lot to change that perception.

On photo First try at the moon in the Astro photography challenge (1 comment in total)

The moon is quite bright! Try 1/100 second at ISO 200 at about f/8, maybe f/5.6, and you should get a nice exposure and a sharper image.
The earth moves 360 degrees per day = 15 degrees per hour = 0.25 degrees per minute = 0.00416 degree per second, so 0.000416 degrees in 1/10 seconds. The moon spans about 0.5 degrees as viewed from earth. So in 1/10 second it has moved 1/100 of its diameter. That's noticeable! I encourage you to try 1/100 or 1/200 sec at ISO 200, and compare.

SHR100: Why is there a limit to the date of photography?

The person who makes the challenge apparently wants to increase the chances that you took the picture because of this challenge. As opposed to digging something from years ago that might be suitable.

QuarryCat: But if you are passionate to photography, you will at least need the 14-140 mm and it is still small and light enough for a long journey!
I don't see any camera maker today, who can beat this combination.
no Olympus (the 14-150 mm is light but optics and mechanics are worse),
no Sony (the 18-200 mm are far to big and heavy)
no Samsung (the 18-200 mm is big and expensive)
no Canon (the don't have a super zoom yet!)
no Nikon (they have only half the sensor size)
no Fujifilm - the 5.6/18-135 mm is close but by far to expensive and it is only 135 mm

I have the 14-140mm newer version, and I am quite impressed! Although at least fully extended it is not quite as sharp as the Leica 25mm f/1.4 , I have been impressed with how sharp it is! I have the pictures to prove it.
