On Week in Review: To boldly go article (66 comments in total)
In reply to:

thejohnnerparty: I am curious - why don't we see the Milky Way in the background? This is deep space, no light source to speak of. Are we looking at a cut and paste?

Images taken of Pluto during New Horizons' approach should have the Milky Way in the background as Pluto is in Sagittarius and should appear close to Sgr A*. But due to DR limitations, the background is black. Remember that New Horizons was launched 9.5 years ago, using 10 year old sensor technology.

If you exposed for the faint background stars, the Pluto would be overexposed. The same same "observation" have been made by moon-landing deniers (no background stars).

On Phase One 645DF+ with IQ250 field test article (141 comments in total)
In reply to:

Clint Dunn: Interesting article, I think most of us would love a kit like that if we could afford it. That said, I guess I'm going to be 'that guy' and say I'm a little disappointed in the photos. All that fancy kit and not even one decent landscape shot?? The pic of the beach is devoid of any interest and has a slightly crooked horizon to boot. The only pic I wouldn't have deleted here is the B&W portrait of the kid, I like that one.
I guess it's easy to be the critic when I'm not the one writing the article but honestly, on a site with this visibility reviewing gear of this caliber you would think you guys would step up the game a bit.

Article also missing the obligatory cat picture.

Zeisschen: I love that Zeiss went with the Touit look and rubber focus ring. For me those lenses have the best touch ever. I can't understand how some people still want a lens with edges, corners or this ugly DSLR look. Simple, clean, industrail design, that's what germans are good at!

I think the touit 'look and feel' are terrible. Their surfaces are too smooth and slippery, at least in my hands, for quick lens changing. I prefer grooved surfaces for good gripping. Also what's with the DARK blue lens index buttons? They're hard to see against the black plastic of the lens, especially under low light. The location of the lens release button next to the grip on an A6000 is also a poor design on Sony's part. Its hard to get my big fingers in that tight space. Just more poor design features by people who do not use their products.

mosc: You know I had a humorous thought. Hassleblad could sue saying this is a duplicate of their product. Then Fotodiox could counter that "How can Hassleblad say that the only thing that made the Stellar such an incredible camera compared to the RX100 was just a $1,000 wooden grip? We're insulted on their behalf"

I bet Hasselblad has a design patent for their camera, not a copyright, but I am too lazy to search the patent files.

Heschulz: I updated my Zeiss 55mm f1.8 and now I can say that the camera takes less time to start. By the way, I have an a7R.

Before update: takes about 7 seconds to start when changing the battery and about 3 seconds without changing the battery.
After update: it takes about 5 seconds and 1-2 seconds.

See my reply above.

Dan Mundy: I was able to download the lens firmware from http://www.sony-asia.com/support/productcategory/dslr+camera

esupport.sony.com didn't have them.

Found the lens firmware page for FE 35mm f/2.8 (http://www.sony-asia.com/support/download/602227/product/sel35f28z). Similar link for FE 55mm f/1.8 (SEL55F18z). Lens' firmware files not up on Sony USA site yet.

On Nikon 1 V3 First Impressions Review preview (648 comments in total)
In reply to:

Sad Joe: It'll be a bargain at 1/3 price ! Sorry but whilst the V3 is a step forward neither Nikon nor Canon (I use both brands) have got serious about mirror less (yet) my fav camera is an EOS-M (don't laugh) which must be the most underated Canon ever. Yep - V3 for £300 - bargain - start the que here - cause at £800+ Nikon aint gonna sell any….I strongly suspect that many leading retailers have REFUSED to stock it…..

While I like the Canon EOS-M for static subjects, I found it to be useless for moving subjects. Its autofocus is SLOW, SLOW, SLOW.

In reply to:

Robert Soderlund: D800.. which one is measured here, the camera or the lens itself? Pretty hard to compare lenses when the tests are done on different formats and cameras altogether.

Must have some sort of a standard, as in same camera for every lens.

"...Must have some sort of a standard, as in same camera for every lens."

How do you test a Canon (or m43, etc) lens on a Nikon D800?

On Sigma 50mm F1.4 DG HSM | Art Lab Test Review preview (574 comments in total)
In reply to:

mike earussi: I commend Sigma for completely changing their design philosophy. Once known as one of the worse lens manufactures only a few years ago (to the point where Lens Rentals quit carrying their lenses due to so much mechanical failure) they now are producing some of the best lenses around. Only time will tell how durable they are, but hopefully they will prove to be as good mechanically as they are optically.

I agree and plan to buy my first Sigma lenses in almost 20 years. My first Sigma zoom lens purchased in the early 1990's fell apart: the lens elements fell out into my hand because they were held in place by double-sided metallic sticky tape!!! This fiasco was also noted in several websites at the time, most notably IIRC, it also happened to the founder of photo.net.

I am waiting for the rattlesnake skin version.

+1. It's for people who cannot take pictures, but have too much money (see http://www.dpreview.com/forums/post/53530570).

On Chicago-based Calumet Photographic closes U.S. stores article (195 comments in total)
In reply to:

DanielFjall: It happens all the time. If you ain't big you just can't compete - especially in the US.

It's happening in all retail segments, not just phtography. Recently, Staples (office supply chain in the U.S.) announced that they will be closing ~20% of their stories as more than 50% of their sales came from online customers.

I will miss the the Calumet,Cambridge, MA store-it was a good place to hang out in the good old days.

Thirty five years ago, everything was in the cloud (data, software)-they were called mainframes then. I had a constant running battle with the 'computer center' geeks who wanted to control their domain. The introduction of the various PC platform freed me and others from this tyranny: for the first time, I was able analyze my own data and did not have to reply on some faceless geek several hundred miles away at the corporate computing center who had no clue about my work. I got to 'own' my software and computer. No way I will revert to storing my data or files on some server far far away. I will not pay any rent to Adobe or anyone just. Time to start looking for other software.

bobsphotos: Looks like a small bear to me, about 4' tall. What did you run for?
" Two guys are chased by a grizzly bear. First one says" What are we going to do?" the second says "I am going to out run you and hope the bear is happy chewing on you."
Old joke.

Agreed. it looks like a little cub, hardy 500 lbs. What a girly man, ;-)
