On Hands-on with Panasonic Lumix DMC-LX100 article (76 comments in total)

This is looking like my next camera, it or its Leica sister.

Cal22: The LX100 aims at people who want an all-in-one solution. And the camera has a lot to like. I like especially the full manual control with control dials on the top plate for your right hand and a ring at the lens' mount for your left. And the camera body is big enough to making it not fiddly.

What I don't like: The camera has no tilting rear screen and no tilting EVF either. How to shoot from ground level? And a bundled flash should come up with more options than a built-in flash can provide; whether Panasonic will deliver in this respect, we may doubt until now.

The lens' zoom range is a little limited. Let's hope the image quality lives up to the name Leica!

How many times have you really used your cameras at ground level? Even if you do a lot, tilting VF/screen are not actually needed. I find the tilting screen useful for video, since you can hold it in a more comfortable position for a long time. That is relevant, shooting at ground level, not really.

Only neg so far for me: it's ugly when lens is in use, those "petals" look awful and possibly easy to break and even a hazard as they could hurt someone.

rhlpetrus: Very interesting. Doesn't it have a dial for setting aperture in manual mode?

Nice! Now only AF may be an issue, hopefully it's as fast as the recent m43's ones. Makes for a very nice compact, indeed. I have been using a V1 from Nikon, which is decent, but this sensor would be better.

On Canon EOS 7D Mark II First Impressions Review preview (1680 comments in total)
In reply to:

Lab D: First I read this and then I saw the new Samsung. I don't know anyone who buys Samsung, but it seems to beat the 7D in every spec.
For example 10 FPS is not exciting when others are offering 11,12 and 15 FPS. "Full HD" video is boring when other shoot 4K.
I just hope the 7D does use the same technology in this new sensor as found in the Rebel T2i.

Besides sensor tech, the 7D2 is the top APS-C camera out there, make no mistake about it. The AF and the metering are brilliant, and 10fps seems to be enough to all sports pros.

Nice stuff, Canon copied the Leica, including clockwise direction for attaching mount, Nikon went the Zeiss way. BTW, Nikon, in the 30s, brought some Zeiss engineers to start their lens design group.

greypixelz: Interesting story!
As far as I know, Nikon was producing optics for the imperial army before they ever copied the Contax RF. Btw, Nikon stands for Nippon Ikon, as in Zeiss Ikon ;)
As it looks, Kwanon is much more of a grass root company than Nikon.

I think you know nothing about Fraunhoffer, Zeiss, etc, do you?

justmeMN: I selfishly miss John the most. So many great songs never written and recorded, because of his murder. He was always my favorite Beatle.

I heard Paul on the AR studio TV show playing and singing I've Got a Feeling, then I waited to hear John singing "Everybody had a good year ..." It never came. Yes, he's much missed.

Lucas_: Great memories, I was 21 then! I still have that vinyl Album bought at that time ( among others from The Beatles ).

I was 13, and got it the week it was released in Brazil. It was mono, of course and I still have, pretty scratched though (I'd take it to the beach and played it on a portable Phillips player). A huge success with the 12 year old girls.

Robgo2: The covers of "Abbey Road" and "Sgt. Pepper" are almost certainly the most famous in the history of recorded music and are fitting icons for some of the greatest pop music ever.

My 11 yo daughter wants to go to London and Liverpool, that says it all. Probably, myself, the song that I used to listen over and over was Hey Jude. Still today, anytime it pkays, I stop whatever I'm doing and listen until the chorus fades away ...

I still remember getting the album, going home and listening to it on a Phillips player tgat you pulled the arm out to turn on. A friend came up, he was more of a Rolling Stones fan, but after listening to Come Together and Something he smiled and said, "well, this one is better than the last RS album"', which, I think, was Let it Bleed. Good and simpler times ...

David Smith - Photographer: I think Nikon now uses the same sensor that Sony uses in the a7r. Amazing detail is now also available for Nikon users.

"The problem with this 36MP sensor is lack of DR" ouch! Well-documented? Where? Never read a more nonsensical statement anywhere about a camera!

Lens issue: in RAW, lots of fringing, visible as you move into the corners. Also , lens seems soft in corners. Which lens was used?

The 64 base ISO value may mean more than exposure settings flexibility, but for that we need to wait for proper lab and field tests.

Re guinea pigs, I always get the s versions of iPhones, never regreted it.

Edit: lots of guinea pigs out there

This is getting very upsetting, first Nikon drops its PP soft, now Apple, this Photos will likely be something related to iTunes, that horrible Big Brother idea by Jobs.
