On article Hands-on with Hasselblad X1D (816 comments in total)

OK, it's cute and small. Does it come with a pill we can take to shrink our hands so we can operate it or is it just another piece of jewelry?

On article Hasselblad to announce 'game changer' next week (460 comments in total)
In reply to:

GabrielZ: MF mirrorless, it was bound to happen at some point. Personally I thought Fujifilm would be the first. It has been rumored for a while now that Fuji would introduce such a camera at Photokina this year. Seems Hassy has beat them to it. At least Fuji will likely manufacture the lenses for this Hassy and still might introduce their version at Photokina after all.

Fuji built at least one Hasselblad body in the past. This could well be Fuji's rumored MF camera. l

400 watts is not a measure of light output, that will be lumens. And don't say compared to an incandescent as their output varies by more than a factor of four for a given amount of consumption. Light output is measured in lumens and efficiency is measured in lumens per watt.

The best available daylight LED I've found so far is by Phillips with a little over 100 lumens per watt though the CRI it's probably not suitable for serious photography. Note that this bulb is not dimmable as dimmable LEDs are still less efficient though they usually have a longer life than non-dimmable bulbs.

On article DxO OpticsPro 11 brings advanced Raw noise reduction (110 comments in total)

I use Lightroom with an OLYMPUS OMD EM1, a Fuji X-S1 and a Panasonic FZ1000. Overall I'm very pleased with the results I'm getting. It seems like it would be significant extra effort to preprocess my raw images in DxO before importing into Lightroom. So this leads to questions of whether the results be superior to Lightroom and if so will they be visible to anyone other than a pixel peeper?

TwoMetreBill: "If you have a RAID array that's gonna take care of your uptime anyway (that's what it's for anyway, not for backup)."

I disagree. My primary backup is roughly 3TB. Using typical USB3 external drives, it takes about 18 hours to recreate the backup and I lose all my change history. I never get more than 12-18 months out of these external drives, Seagate or WD. Yes they do honor their warranties but I've still lost my history, have no backups for a week or two and then have to wait another 18+ hours before I have a new backup.

So I broke down and bought a Drobo Mini with 4 2TB Seagate drives and a spare on the shelf. In less than year, one of the drives failed. Hot swapped the drive, the system went into automatic recovery while my backup continued to run. And yes, Seagate replaced the drive, even paying all shipping costs.

Impulses

You shouldn't reply to postings that you didn't read, you just sound silly.

My data is on my internal drives (4).

The backup contains a full copy of my data and my change history. So if the non-RAID backup drive fails, my change history is gone. This is true whether using something like Genie TimeLine on Windows or TimeMachine on OSX.

I also use the cloud for everything except multimedia as the HD and now 4K videos my wife shoots with her Panasonic FZ1000 are just too large.

So even should the Drobo fail in a way that corrupts the drives, I still have the originals of all my data and only lose some of the change history (some is maintained by the cloud service I use). Furthermore a failed Drobo rarely corrupts the drives so I just get B&H to overnight me a new one (I'm out of warranty) and I'm back up 24 hours later.

Questions?

Barometric altimeter, give me a break. My wife and I were eating lunch one day in the Rocky Mountains. We have a very good barometric altimeter. In less than an hour, sitting still in a parked car, the altitude changed by a thousand feet. This thing has GPS with accuracy to at least 40' out of water. Out of water, barometric altimeters are little more than random number generators.

Were the K-1 an all electronic camera with a global sensor (IE mirrorless and no mechanical shutter) then I'd switch from Olympus. The improvements are significant but not sufficient. This could be considered pixel shift version 2, waiting for version 3.

Waiting for the Lightroom plugin. I simply don't have the time to spend fighting with the full PhotoShop or GIMP.

As Hassy lenses are made by Fuji, at least some of them, a few bucks can be saved by picking up the same quality in the X-mount.

In reply to:

justmeMN: Canon and Nikon have global shutters, they work anywhere in the world. Oh, that's not what Panasonic means. :-)

Not in this dimension, perhaps in another universe.

A focal plane shutter is only global at or below the minimum flash sync of the shutter.

To illustrate: assume the flash sync speed is 1/250 sec. This means the shortest time the shutter is completely open is 1/250 sec. If the shutter speed is set to 1/1000 sec then a slot 1/4 the width of the sensor is being exposed at a time. This is used to great effect to create a sense of motion when shooting high speed action.

And of course for video, Canon, Nikon et. all. use conventional CMOS sensors with rolling shutters. Global CMOS shutters are very rare and mostly limited to high end cameras. Outside of pro video gear, global shutters have mostly been limited to small sensor CCD video cameras.

99.9+% of all sensors are made for phones and cars with this rapidly trending to 99.99%. Sensors for phones/cars are sold in the billions, for cameras in the millions. Then there are all the new smart devices which need billions more. Sensors for traditional cameras just don't matter financially to a corporation.
The only thing saving camera sensors at this point is that cameras are marketing tools that manufacturers use to show off their technology. Sony, Fuji and Panasonic have always lost money on camera gear.

What we photo enthusiasts have to hope is that somebody decides to keep making sensors for cameras.

On article Phase One 645DF+ with IQ250 field test (148 comments in total)

Nothing needs to be mirrorless more than medium format cameras.
Back when I was shooting with a Hasselblad 500C and 80mm lens, 1/125 was the slowest shutter speed that could be used handheld for a 5x enlargement (i.e. 8x10 print). Even then the camera needed to be braced against something solid. For 16x20 prints, that minimum went up to 1/250th. With my Rollei 2.8F, I could hand hold down to 1/30th for 16x20 prints; a twin lens reflex for those not familiar with it.

On article Canon PowerShot G3 X: What you need to know (614 comments in total)

Finally a camera to replace my Fuji X-S1, IF it is large enough to be operated comfortably by someone with adult sized human hands and isn't just another jewelry camera.

My wife has a Panasonic FZ1000: very nice image quality but there is so much slop in the manual controls that I don't find it usable. In fully auto mode, it works well for her.

My son has the Sony RX10 with ok IQ but definitely inferior to the Panasonic. The 200mm lens is also too short. The II probably fixed the IQ problems with the sensor. Disappointed that Canon is using this particular Sony sensor but it will still be superior to my current Fuji.

I won't be buying for a couple more months so Fuji could still come out with a X-S1 replacement or Olympus a 12-200 (or longer) travel lens but I doubt whether either of these will happen. Oly 12-200 is 24-400 equivalent.

So the specs and price are right, just have to wait for my local camera store to get one in to see how it handles.

In reply to:

Scottelly: Is anyone else wondering why this sensor gets BSI? I mean aren't there 24 MP APS-C size sensors out there that are like WAY more densely packed with photo-sites? Why aren't THEY made in the BSI configuration?

BSI is a technology for reducing noise and extending dynamic range, great for tiny sensors like those in phones. However it does have a downside, bleed between photosites. Just compare images for the 1" non-BSI sensor in Panasonic with the 1" BSI sensor in Sony and you can see how the Sony, in comparison, lacks clarity. No big deal for folks just shooting JPEGs, storing their images on the web or emailing them but for those attempting to produce high quality images for printing or viewing on the better 4K TVs, the difference is quite noticeable.

Of course since Sony throws away over 90% of the image quality with their 11 bit lossy RAW capture, nobody is buying this camera to get high image quality anyway. It's just a very expensive point-and-shoot.

Geared heads are like Porsches. Love or hate em, nobody is neutral unless they've not spent any time with one.

The precision adjustments are wonderful.

I like my JR but admit the vertical range limits are frustrating. I'll probably get a super heavy duty ball head to mount between the legs and geared head for those situations.

I've always found ball heads frustrating though perhaps I've just never tried a good enough one.

Sony will focus on sensors for vehicles and phones, each heading rapidly toward a billion sensors a year. Sony is doing extremely well in this market. Sensors for cameras, a rapidly declining market measured at less than 1/10th of one percent of the phone/ vehicle market.

With a growing multi-billion sensor market out there, they will soon stop wasting their time on the collapsing multi-million sensor camera market.

My worthless opinion, within 5 years, only Panasonic will be making camera sensors.

If Pany just made a full frame version of their current 4/3rds sensor, it would be 64 MP. When it comes to sensor technology, Panasonic is the world leader; not Sony, Samsung, Fuji or Canon.
