In reply to:

The Squire: Any info on the 4K video bit-rates? Assuming 100Mbps, but not listed above.

Bit of a shame that, like the LX100, they've not offered a high bit-rate 1080p mode.

100Mbps 4K and 50Mbps 1080p would be nice to have.

Unfortunately we don't have a field in our DB for bit rate (yet), but it's 100MBs for 4K and 28Mbps for 1080p.

bazzap101: Some typos in the Specs list regarding Built in Flash :-)

Can you be more specific?

In reply to:

spatz: From the waterfall and aircraft museum shots, edge sharpness on the 7-14 appears very good (at least stepped down to f/5), and I couldn't detect any chromatic aberrations. It would be great to get some shots at f/2.8. While these scenes probably called for more DOF, if we are to evaluate the lens, some shots wide open would be appreciated. Also, flare is important.

The 7-14 could become my second "pro" lens. If the 40-150 price evolution is an example, street prices should be 1/4 to 1/3 below MSRP in about six months. I am sure the 8mm will find it's fans, but it is just not for me.

There are now a couple of F2.8 shots at the top of the gallery.

Stephen McDonald: Well, these photos look better than others I've seen previously from the SX60. I had considered its performance to be inferior to that of the older SX50. But Jeff Keller always seems able to squeeze more out of such cameras. So this is not actually a "real-world" gallery as stated, it's Jeff's world, that not many others are able to inhabit.

I appreciate the compliment, though it took four of us to put this gallery together. But thanks to Sam Spencer for risking his life to take a photo of the middle of the river!

In reply to:

Wesley Byrne: Not too bad, really. Seems perfectly fine for photos for the web at up to about 2000 px max dimension. But I wouldn't want to make large prints or crop much with photos from this camera.

Is that "mountain lion" what many of us would call a bobcat?

you are correct, sir.

In reply to:

Kwick1: Why the lack of specs for the 24-70?

They're in the table above. The two lenses have much in common so the table cells are combined in those places. If you look at size and weight you'll see the differences.

On article Hands-on with the Pentax K-3 II (531 comments in total)
In reply to:

DStudio: "The K-3 II uses the same D-LI90 battery as its predecessor, which can capture 720 shots per charge, though that number isn't directly comparable to CIPA figures for other DSLRs in this class, since the K-3 II has no built-in flash."

Interesting statement. Usually the lack of a built-in flash is a sign of a more "pro-level" camera. Perhaps the lower price is causing some confusion as to its true "class." Let's hope its performance proves this to be true - that the lack of a flash is actually common amongst its peers.

I think the point is that the battery life can't be "officially" compared to the original K-3, D7200, 70D, etc, as a flash is required to perform the CIPA test.

DaveE1: Next week, Jeff Keller write a long piece explaining why he doesn't like eating apples when he wants an orange.

Photos is not supposed to be Aperture. If it was, it would be Aperture. Use an application that does what you want instead would be the best advice.

What Turlututu said.

In reply to:

PeterD07: I do think that asking if Aperture users will like Photos is the same as asking if Mac Pro users would settle for an iPad. Seriously now, what's going on here? I had to read the title to this article three times to make sure it wasn't a joke. I was about to elaborate on why, as a wildlife photographer with a professional workflow, it's not possible to even consider Photos, but decided there was no real point in doing that. None really.
I think that rather than to have written this rather unremarakable article, they could have become more serious, more intelligent and informative, if it submitted real alternatives to Aperture, you know like pro apps and what Aperture was designed for. Photos is not even a good amateur app. Maybe it's just me but common dpreview, are you beginning to resemble Apple?

This article wasn't meant to be a comparison of Aperture vs other pro apps. It was an article about what Apple has dumped upon Aperture users, and whether people could stick with it and be happy, or not. (I think the answer to that question is pretty clear).

In reply to:

Gollan: This was an interesting article. I was surprised to hear that Photos was going to be the Aperture replacement and I'm impressed that Jeff Keller even gave it a try. It seems to me that Apple has always catered to creative enterprise and it is somewhat surprising to see them back away. (Frankly, Apple has a history of blowing hot and cold in other areas too, such as the use of iPads in Education). My friend is a professional artist who uses iMacs, but she also uses a DSLR to produce much of the raw material that goes into her work. What message is Apple sending to her when they have taken away one of the powerful tools that is in her workflow?

Apple didn't really call it a replacement, but they sort of hinted at it:

"With the introduction of the new Photos app and iCloud Photo Library, enabling you to safely store all of your photos in iCloud and access them from anywhere, there will be no new development of Aperture. When Photos for OS X ships next year, users will be able to migrate their existing Aperture libraries to Photos for OS."

arscii: You lost Aperture and its replacement? That is unlucky.

The power of the humble comma.

Wait, where? I am a comma snob and hate to miss these things.

abortabort: Doesn't appear to be the same EVF. Would be quite interested if it had RAW capture, but sadly no.

Good find, thanks. And agreed about Raw.

On Samsung NX1 Review (1263 comments in total)
In reply to:

mpgxsvcd: Thanks for the great review but why haven’t you reviewed the “yet unrealesed” Canon 5DS yet? It definitely is more popular than this camera. You guys are just biased for Samsung aren’t you? You gave the Gold award to a camera simply because it does so many things right and so few things wrong. Whatever happened to giving the Gold award to the camera that simply did the one thing I like the best?

Seriously if you guys can’t predict the future and read my mind all at the same time I am not really sure what you all are good for.

Said in Jest of course. Thanks for the great work on this review. It was truly an outstanding review for an outstanding camera.

We had a 5DS for about a week and we neither able to review it nor post photos. Hopefully a final production model will make its way here soon.

In reply to:

Clear as Crystal: Barney, can I suggest that one way to reduce the shouts of "foul" from people who haven't had their choice of brand reviewed may be to post something on dpreview which states when you asked for a camera from the manufacture, when it was received and a tag showing pending, making our first impressions, under review or completed review? that may show where the sticking points are rather than you lot needing to defend yourselves from the same accusations of ignoring brand x after each review.

I'm not Barney but I would say that our readers should be able to trust that we're not ignoring brands because of "love" for another brand. It comes down to what products we have on hand, our current workload, and what our statistics show people are most interested in.

I think that having a "status" would just make things worse, TBH.

It was the 18-300mm VR of all things. I've noted this in the review.
