Very, very nice BUT....for many the question will be is it worth that much more than a GH4, much less the GX8.

doctor digi: Whenever I see the term "reaching out" I think of monkeys in a tree. Nor do you end a "Dear..." letter "All the best"; it would be "Yours sincerely".

I think I'll stick to writing my own letters, thanks.

There is nothing that says you can't edit to taste.
You're a Creative! It's what you do.

dpfan32: And again: way more expensive than the predecessor...
And what replaces the FZ1000 in its price range???
It's like buying an iPhone for 800€ and next year they charging 1200€ for their improved model...
It's ridiculous...
Camera maker don't want to produce affordable cameras anymore.
Their target market seems to be only enthusiasts who are willing to pay more than 1000€ for a camera. Let the others shoot with their phones...

"Camera maker don't want to produce affordable cameras anymore."

I would be quite willing to bet that the "affordable camera" crowd is happy with the camera in their phone. I don't think it is a big secret that camera sales volumes for dedicated cameras are falling, which has the reciprocal effect of pushing prices up.

Satyaa: Question for FZ1000 owners:
I used FZ1000 briefly. I am planning to get one for travel. My video usage will be limited/infrequent. I have no speculation if that will increase in future or if I will have video opportunities/needs during travel.

I use Nikon D7200 as my main camera for hobby and unpaid work, the only limitation being which lenses I can carry in any given situation.

From your experience with FZ1000 and what you see in this new model, which one would you buy if you were in my situation?


Name a bridge camera that has a battery grip. I don't believe any of them do. That's pretty exclusively a DSLR class and up feature.

thubten: Why does an adapter cost as much as a lens?

In no particular order:
1. The development costs are fixed.
2. The sales volume are low. This is a pro only item. People with low-end lenses costing less than this adapter are unlikely to buy this at any price. They'll buy more low-end lenses instead.
3. The competition is limited to non-existent.

raindance: The space savings on the Sony A7 is reduced once you factor in the lenses which are every bit as big as other FF lenses (and in some cases bigger than Nikon/Canon offerings).

The space savings of the Sony A7 series bodies are still further reduced when you factor in all the underwater housings for all the gear. There's obviously a lot more than the camera body and lens.

On article Samsung launches first removable UFS memory cards (177 comments in total)

Just as SD/SDHC/SDXC has achieved market dominance, someone has to come up with yet another flash card format. Good luck with that, Samsung. Maybe you should ask Sony how well MemoryStick worked for them, seeing as Sony has made almost everything they sell work with SD/SDHC/SDXC.

PropaPH: I'm a media professional and spend all day looking at images on a computer, in a company of more than 500 similar workers. The overwhelming trend in software interfaces in the last few years has been towards neutral-to-dark backgrounds to help reduce eye strain for people who work long hours constantly staring at a monitor. Sites that use large areas of white background are visually uncomfortable and seem amateurish to me for that reason.

One reason black backgrounds cause less eyestrain is because it greatly reduces the effect of monitor flicker. I went through a period of eye problems years ago where this was a huge issue for me. I was so happy when I found the Sun workstations I was working with at the time had an invert function for the display.

I now know I'm in the minority, but thank you so much DPR for keeping the light text on dark background. This is my first time visiting the site with the new default white background and it took only seconds to get back to 'normal' (whatever that is).

phoenix15: Only if Lenovo let the motorola brand alive. Only moto is not enough.

More specifically, Google bought Motorola Mobile Devices, stripped out MMD's patent portfolio for enhanced ammo in the Microsoft/Google/Linux patent wars, and sold the remainder to Lenovo.

I like them. I have a first gen Moto G and they have been very good at pushing out the Android updates/upgrades.

GotoDengo: DPR, shouldn't you add a "NOTE:" to this story indicating the results appear to be hampered by a sub-par lens, and a substitute is on the way?

Your comments make that clear. It needs to be in the story.


No. According to the Zeiss USA website, Otus is only available in Nikon F and Canon EF mount.

Joe Ogiba: Smart idea of Ricoh using the older 36mp Sony sensor to keep the cost well under $2K. Too bad Pentax did not have 4K video mode with H.265 like the Samsung NX1 to increase sales but it looks like most Pentax users are not interested .

Going with an older sensor and getting 4K video is simply not going to happen.

I did note Pentax got the video data rate almost up to the AVCHD max. spec. and the audio sample rate up to 48 KHz, both big improvements.

DoubleDash: Kodak and Polaroid. Very true. IPhone one #1, ridonculous.

The fact that a computer is not on #1 is just shamefull.

@Roland Karlsson
Yes, there were computers before the transistor, but none of those would fit in a house, much less under or on your desk.

Robert Zanatta: Pretty good battery life.

Is like to try the viewfinder.

But only USB 2.0?

I noticed that also.

I am going to assume that on the smaller APS-C bodies space is at a real premium - and the USB 2.0 connector is undeniably smaller.

For fastest import of media, I would remove the card from the camera and stick it into a USB 3.0 card reader anyhow. Purpose built hardware has a way of being faster than what is built into most cameras.
