On Another Hasselblad rebadge or Photoshopped hoax? article (187 comments in total)
In reply to:

Photoman: Victor Hasselblad would turn over in his grave. Hasselblad have no imagination, no original designs (or designers just out of college) and no clear path to take them in the future. They are no different from a "West Coast Customs" business, were they build nothing, but tart it up and charge stupid prices. One day (maybe 5-10 years) dpreview will run an article after Hasselbald go bankrupt and "Where Did They Go Wrong?"

I don't think it is going to take 5-10 years.

(unknown member): Looks like a very sharp lens but difficult to know for sure as your sample images are awful subjects to determine that and/or only one image is raw processed. It doesn't help either when you guys can't be bothered to rotate your images.

Come on guys; you can do better than that!

Nice subjects, photos appear in correct orientation. Mr. R Butler, the work and effort are appreciated. Great job.

johnmanoah: When talking about innovation, why aren't these companies considering these easy-to-have innovations?

1. Rotatable (up/down) flash head - so that we could bump the flash to a ceiling or elsewhere. Currently, the in-built flash forces light upon the target which usually results in bright spots or over exposure

2. 3G sim card slot - so that the camera is connected to the internet and sharing/storing is simple

3. Bluetooth

4. Touch screen

Ricoh/Nikon/Canon - Are you listening?

@ fs750

I suspect that manufacturers have gone to wifi instead of Bluetooth because: a) Every laptop & tablet has wifi, Bluetooth is more hit-and-miss. b) Free wifi is almost everywhere so if the target is connecting to and uploading to services on the internet, talking TCP/IP from the get-go just makes more sense.

On SanDisk introduces first CFast 2.0 memory card article (58 comments in total)
In reply to:

HowaboutRAW: Does this new CF card design use pins within the camera? SanDisk, and camera makers, need to be really clear on this point.

Pins are trouble. And of course neither the XQD cards nor SD cards use pins.

Read the press release.

On SanDisk introduces first CFast 2.0 memory card article (58 comments in total)
In reply to:

Joe Ogiba: Sandisk is pricing their new 256GB 160MB/s CF card at $1,809.99 and the small 16GB version at $219.99 and it looks like this will cost even more.

I paid $18.95 w/FS for a two pack of 16GB 94MB/s Sony Class 10 UHS-1 SDHC cards at B&H that is more than fast enough for my current cameras shooting 1080p60 etc. The new UHS-II SD cards are coming out next month with up to 312MB/s speed so I don't see any consumer camera needing more than that even for 4K. The ARRI ALEXA XT camera body pricing starts at $78,558 so the cost of CFast 2.0 cards is not a problem for ARRI users.

@ HowaboutRAW

The Canon HF G30 shoots AVCHD/MPEG4 at a max 35 Mbps which works out to 4.25 MBytes/sec. No strain for Class 6 or 10, much less USH-I or UHS-II.

fastglass: +1

Long live CF!

While the State of the Art here certainly isn't affordable or needed by most users, the development of the media means its still a viable technology - a good thing for all current CF users.

When a technology becomes obsolete - the availability suffers & prices seriously increase.


At this point CF has begotten two children: XQD and CFast. Given flash formats have been consolidating, I don't see that kind of fracturing as a good thing.

joe6pack: I don't get it. What is the hub for? How is it different from a USB hub? Why does a photographer need so many card readers all at once?

I have personally shot events (video) with up to five cameras and two hours in length. The full data set was about 125 GB. Being able to import four video streams simultaneously and walk away while the computer does the work would be very nice. Just because YOU don't need/want it does not mean no one else does.

GabrielZ: "bought-out by private equity group Ventizz" - I didn't know that! Now it makes sense why the venerable Hasselblad is now producing this crap for all those tasteless nouveau-rich with more money than sense!

I believe Ventizz is doing a spectacular job of pile-driving the value of the Hasselblad name into the ground.

Benarm: this Leica reminds me of Hasselblad Lunar which is just a rebadge of NEX-7

Disagree - The Leica is in fact attractive.

attomole: That is the best shirt and tie combination seen on any executive since the 70's

John Carlson, Senior Manager for Sales and Marketing Pentax , I salute you.

Great Cameras by the way.

He wanted to be sure if anyone shot video, they would get blinding aliasing and moire.

In reply to:

JONNO G: With the new image processing which will shoot better, k30 or k50?

I would expect them to be very close. They use the same glass, have the same sensor, have the same image processor. The principal difference seems to be processing for 'jaggies' - so reduced aliasing, and higher ISO's. How usable the latter really is...when I test my K-01, which shares much of the same, I don't want to go where there are two digits to the left of the comma. To much noise.

I wish Pentax would get serious about high quality video.

jaygeephoto: In the great tradition of lazy journalist, I'm going to first re-post something I wrote almost a year ago when I first heard about this monstrosity:

I like it! Where can I go to see one outside of captivity? Palm Springs, Boynton Beach? It's like a Rolex watch with Timex innards. Maybe now Saab can save itself by putting it's badge on a Subaru or GMC. Wait a minute, someone is eyeing my gold Leica with Alligator trim. How do you pronounce Maybach anyway? I have a a lot of questions.

There's also a Ferrari Red edition of an H4D40 - no I'm not making this up, I'm not that creative!

Takes 'Pimp My Ride' to quite another level.

MrTaikitso: Why?

The number 1 phrase attributed to P. T. Barnum is "There's a sucker born every minute". Turns out it was actually said by a Mr. David Hannum, who was criticizing both Barnum and his customers, but in the popular culture it is P. T. Barnum to whom it sticks.

Chris2210: At last someone has had the good sense to offer me the perfect accessory to my Ferrari F40 Traveller. Now if only someone would fabricate some hand lathed teak wheel trims I'd gladly pay $3,000. Each.

You losers can't spot real innovation when you see it. Here's the first camera in the world that can see you coming.

Don't you mean "Here's the first camera in the world that can see the suckers coming." ?

In reply to:

G Sciorio: Glad to see Pentax pushing out something more traditional design wise. While the MX-1 is a great looking camera I'd love to see a interchangeable lens version with a bigger chip as well.

Would be nice but that would put the Q line of cameras out of business.

WilliamJ: Another good advice: take away suddenly the expensive cigar your celeb is smoking from his or her mouth, you will get an unforgettable picture. Follow the example of Yousef Karsh who dared this stratagem and got one of the most iconic ever photograph ! Cf: http://iconicphotos.wordpress.com/2009/07/31/winston-churchill-by-yousef-karsh/

It could work on Madonna or Arnold Schwarzenegger...

Sort of like this one of J. P. Morgan

aired: does it make anyone wonder why NASA didnt use color sensor for their Mars photos... and the moon photos...

black&white is often associate to be authentic... but is it real or not?!

It comes down to data transmission rate, which from Mars, is very, very, very slow.
