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.

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.

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.

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.

"Here's the buttock-clenchingly expensive Zeiss Otus 85mm f/1.4 Apo Planar T* ZE - a $4500 lens - brutally converted into a $2250 42.5mm. Shame."

Cutting the lens in half doesn't change the focal length. Otherwise an interesting article.

jack123torr: Hi all,

I am tempted to sell my Nikon D7100 + 18-200 lens (old vesion, "red NR") and replace by the FZ1000. It is smaller, lighter, more options (rotating screen, panorama, wifi, NFC, etc etc etc).

The only point that concerns me is: "will there be a noticeable difference on 4x6 prints at ISO 3200 and 6400"?

Any comments? Thanks.

If 4x6 inch and not foot prints are your target, there is no need for you to spend more than a couple hundred for a camera. You won't see a difference between a Fuji F900 and a $100,000 Hasselblad system.

Peiasdf: Wow, for the price of these adapter, might as well pick up an extra Rebel SL1 when you want to shoot Canon lenses.

Lens bulk, what are you smoking?
The Canon 100-400 yields a 200-800 equivalent. Now what is the size weight comparison with the 800mm Canon canon, I forget?
This smart adapter is just the thing to get me to buy into the OMD system though it would be to enable the operation of a Canon 100mm macro.

starwolfy: Before talking about isos people should learn what a correct exposure is. I shoot iso400 film hand held at night with no tripod on a 55 years old film camera. Look at my results on my gallery (just night examples of what I do, me who is just an amateur).

iso 400.000. Is it what you guys need ? Really ? Really ???

What a joke.

Go up into the Rocky Mountains to photograph wildflowers. Set up your RRS or Giottos tripod with your favorite camera and lens, compose and calculate exposure. Then notice that you'll need 1/4000 to 1/8000 sec to stop the fluttering flowers and leaves from the ever present wind. I forgot to mention that you are in the shade to get the deepest and richest colors and that some flowers only bloom in the shade such as the Lady Slipper Orchid or a Coloradian's favorite, the Columbine. The shadows are a good 8 EV darker than sunlight.

Of course multiple image HDR is impossible under 4,000 frames per second due to ghosting.

A beautifully clean ISO above 400K? I'd take out a second mortgage were it available. For now I'll keep saving my nickels for a D3S or D4S.

vadimraskin: What is the point in small camera that needs big lenses? Balancing it is a pain!

The point of a small camera is that they are basically jewelry as Leica discovered 40 years ago. Designing camera bodies for the hands of an 8 years old is an admission that few buyers are serious about photography. This is all about sales and not usability. They even lossy compress the raw images from the A7 bodies and nobody complains.

While WayneHuangPhoto hit most of the top issues, there is still the almighty stupidity of the camera makers.

10's of thousands of Nikon D300/D300S owners did not replace their cameras because of the tiny raw buffer on the D7100.

Fuji is covering every silly mm and f/stop below 60mm with nothing meaningful above 60mm. Where is the 80-400/100-500 long lens, where is the 150mm macro...? If those lenses had existed, I would have purchased the X-Pro and then replaced it with the X-T1 even with the silly top shutter speed of 1/4000th sec. It's got an electronic shutter Fuji, give us high shutter speeds so we can actually use your f/1.2 lenses and eventually long telephotos.

Canon hasn't built a new camera in several years, just 60's Detroit styling changes and miniscule technical upgrades.

Sony,they can't do anything right.

Olympus, the only company getting almost everything right. They now have almost 50% of the interchangeable lens mirrorless market share. I wonder why?
