I don't have a sense of the relative darkness of 0.005 Lux. What is that in EV, if a conversion makes sense?

My impression is that the illumination from a full moon is a lot more than 0.005 Lux. Or not? Maybe a quarter moon in an otherwise dark environment with rural ambient light pollution?

Astronomers rate darkness with the Bortle Scale. Where would 0.005 Lux be on the Bortle Scale, and it applies?

On Hands-on with Panasonic Lumix DMC-LX100 article (435 comments in total)

Looks very interesting.

To me, the lens cap and also a decent lens hood should be included.

It does appear to have too much depth to be even remotely pocket-able, which doesn't seem currently possible with sensors larger than 1".

The grip could have been larger to improve handling, and allow a somewhat larger battery for longer life.

The dumb phone owner who has been reluctant to upgrade is definitely interested. I did try a Android G1 when it first came out, and was underwhelmed.

Price will be a key spec ... as Anandtech says .. "there are no bad products, just bad prices".

Thorgrem: The 400mm isn't a L type? And therefore lacks the red ring?

Out of curiosity, I posted to the Canon SLR Lens Talk forum:
http://www.dpreview.com/forums/post/54386349

Summary?
The DO lens apparently is prone to flare. As is often the case, owners who love them, love them. Previous owners tend to not care for them. Pretty profound, huh? :-)

Daniel Lauring: Big fan of Canon except for their also-ran sensor technology. It is between this camera and the new LX100 for me. I wish Canon had included a hot shoe. That omission might swing me to Panasonic.

RB: Thanks. and interesting to be interacting with a DPR writer. I need to be careful on my WAG's :-)

OT? I wish Nikon would put the Sony 1" BSI in a variant of the Nikon One body. The AF of my J1's Aptina sensor is nice, but I'd rather have the Sony's 1" BSI IQ.

My less-than-informed impression is that the Sony 1" BSI has better IQ than the 1" Aptina. Or not?

In reply to:

l_d_allan: I wonder why the battery life is so underwhelming. Is it because there just isn't room for a larger battery, in order to keep size and weight down?

Or is it "power hungry", suggesting less than impressive engineering?

FWIW: one of my "pet peeves" is that there seems no legitimate reason to not have a real "finger grip" that would also allow a larger battery.

IMO, one of the more important specs on a compact camera is the depth dimension, which greatly influences "always with you pocket-ability". My Canon S110 easily goes in my shirt pocket or jeans pocket.

With a grip that is the same depth as the retracted-when-OFF lens, you don't lose ANYTHING in pocket-ability. A real "grip" on my S110 would significantly improve handling, especially one-handed.

Ok, some weight and maybe a bit higher fabrication cost? However, I don't consider "weight" to be a particularly important spec in a compact camera that has an objective of pocket-ability ... an ounce or so at the most difference?

Technic:
Good point ... the G7x without EVF should have at least as good battery life as its competition.

Of course, all other things being equal, lower weight is better. Pro FF + huge lens gets heavy on a long hike.

But for these small-ish cameras weighing about 300 gr (< 11 oz), I think pocket-ability depth and capture count are more important.

Am I the only one who think 10% heavier for perhaps 2x more captures is a good tradeoff?

Hachu21:
Thanks. I agree that the Richard Franiec accessory grip probably improves handling. However, the advantage of a “native” grip is it can allow a larger battery.

FWIW:
I think there are some cameras where the manufactured offers what I think in an overpriced and easily lost accessory grip that has a battery, but that seems lame-beyond-words to me.

Instead, camera manufacturers should design the camera with a grip corresponding to the depth of the retracted lens, and include a larger battery, ideally the largest battery that will fit.

raay:
IIRC, the "first impressions article" mentions at least twice that the G7 1" sensor is probably the same or very similar to the latest/greatest RX100-3 BSI 1" sensor.

DPR/RB used something like the phrase "strongly suggests" or perhaps "highly likely" or equivalent wording.

DPR even supplied a Sony part number, although that hasn't been confirmed by a tear-down (hint, hint :-)

I would hardly call the sensor "also ran". It appears to be a state-of-the-art BSI-CMOS from Sony.

It definitely is a "me too" sensor, but in this case that's a good thing. I'm pleased to see Canon "swallowing their pride" and maybe "losing face" by using the Sony 1" sensor.

TMI?
This suggests they have a cross-licensing or purchasing agreement with Sony. I wasn't surprised that Sony sold their Exmor sensor to Nikon, as the Exmor hadn't yet gained its stellar reputation.

I'm a bit surprised that Sony would sell their "best of breed" sensor to Canon. Pleasantly surprised !!!

FWIW:
I really, really hope Canon takes the same "swallow their pride" attitude to incorporate a variant of the Exmor full frame 36 mpix sensor in the 5d4 or 6d2, to speed it to market.

In reply to:

l_d_allan: > which should give excellent control over depth-of-field (including at focal lengths useful for classic portraiture)

Hype ... ???

To me, you need at least a m43 size sensor with fast lens to have "excellent control of DOF". Preferably even larger, like a Canon EF 85mm f1.8 on a 6d or 5d3 full frame.

rpm40:
I also will regularly stop down with portraits, such as my EF 35mm f2 IS on my Rebel T3i. Or EF 70-200 f2.8 at 200m on a full-frame.

I'll do that for a bit more lens IQ, and also for more room-for-error in my focus ... mea culpa.

To me, the "shallow DOF look" has perhaps only one eye in sharp focus in a 3/4 pose, and the other eye, nose, and visible ear being noticeably OOF. That isn't a look I particularly care for, and would probably stop down the 200mm f2.8 on full frame a bit.

RB:
Thanks!

Agree that it is impressive if you are used to a smart-phone or a entry level point-and-shoot with 1/2.3" sensor, or a more advanced point-and-shoot with a 1/1.7" sensor.

If anyone asked my opinion on "what would be a good camera for shallow DOF", I couldn't recommend a 1" sensor with wide-angle f2.8, like on the Sony Rx100-3 and Canon G7.

Maybe a f1.8 prime on 1" sensor, for interchangeable 1" sensors like the unique but quirky Nikon One.

I suppose if they were asking because they were frustrated with the large DOF on smart-phones and entry level point-and-shoots, I could comment that the DOF would be less on the 1" with f2.8 wide angle.

But I still wouldn't consider that to be "shallow" ... just "shallower".

I'd have replaced the word "excellent in the article" with "somewhat better" ... but I can be fussy about what I consider poor choices of words.

And ... we shouldn't forget that DPR has "Gear Shop", and is owned by Amazon. Me, cynical?

Also surprised it isn't an "L" lens.

It certainly has an "L" price.

Canon specs are confusing. One page shows max print size of 8.5x11" letter size. Another page shows the MG7520 can print 13x19". Which is it? (probably letter size max).

What about an image captured remotely by the animal triggering a trip-wire? Or motion detect? The owner of the camera may be asleep back in their tend.

Would National Geographic be ok with losing their copyright?

In my experience, Wikipedia certainly pays attention to non-public domain images. I had an official state portrait of a current governor rejected, paid for with taxpayer dollars. That surprised me, and they were correct.

However, I am not surprised that Wikipedia will typically error on the side of anti IP on issues that are not black and white, but rather gray.

I suspect Wikipedia is within their legal rights, but they should remove the image, and maybe even apologize.

In reply to:

MisterBG: Seems like something you could do a lot more easily with digital layers and save loads of printing paper.

To me, exceptionally creative.

I've done a fair amount of Photoshopping, and some composites with layers. However, I think it would be very time consuming to accomplish the effect with layers, so that it had the same look.

So yes, it would save paper.

But ... my speculation is that the actual art work would have a very, very different feel, in person. We have to use our imagination from the small JPEG's from DPR to visualize the real art.

There would also be a "tactile texture" as you handled it, that would be missing from a 2D print.

Philip Lanoue: I can do a reverse image search on many of the images from my wildlife photography blog and return pages of results. Lots of photos are being used in various ways all over the world, and I basically don't really mind or care.
It wouldn't matter anyway, what am I going to do? Sue some web site in China, Russia, or Saudi Arabia?
For those nice enough to ask, I always donate my photos and have done so many times over the years.
Earlier this year I donated a wood stork photo to the Chicago Field Museum that is part of their current exhibit.
I have been quite fortunate with my blog however, I have a nice solid group of honest, intelligent followers and visitors.

I'm aware this "reverse image search" can be done, but ignorant about the specifics.
