In reply to:

AgntMichaelScarn: What's the equivalence of fuller frame to full frame?

This sensor is .79x crop factor from 135 or 135 is 1.266x of this.

Wild Light: This is baaaaad for Leica

Yes a blip on the M's radar. A range finder is a completely different camera. If you're looking for an M you're not even considering this. People who get the S do not buy the M and people who buy the M are not looking at the S. This may be competition for the S, but they have a way to go with lenses. The only thing this really will shut down is the SL line and maybe down the road have an impact on the S line if they improve their lens lineup.

historianx: Delicious! Interested in the battery power, as this is the one hangup with MILCs. Still, this is a game-changer.

Battery is a concern. My more immediate concern is the AF. The sensor does not have Phase Detect AF points, so we're back to contrast detect AF like we were in the very early days of Mirrorless. And with the bigger/heavier lenses it could be pretty slow... we'll have to see how it performs in the field.

Maybe bad for Leicas SL line... maybe. But a blip on the radar for the M line and Hasselblad has a long way to go to catch up to the S line (Leica has a decent range of lenses at this point as opposed to 2).

Different cameras for different needs/uses.

Steven-T: Just watched the Hasselblad live presentation. This X1D is not for me. The sensor size is 1.68x FF 35mm. A Hassy V 6x6 film is 3.63x times FF 35mm film size. I want at least a 6x45 sensor size, 24mp is fine with me. The two XCD lenses are extremely slow, considering the much smaller image circle coverage. I want at least f/2.8 or faster. I am using three f/2.8 V lenses for my film Hassy V, covering a much larger image circle. Bokeh? What's Bokeh! Guess I need to wait longer for the next "whatever brand" . . .

The 1.68x is in area. Going by that metric full frame is 2.35x larger than Nikon/Sony APS-C. If you translate into the more commonly used "crop factor" based on diagonal. We're talking a 0.79x crop factor (or 135 is a 1.266x crop from this sensor). It's a really negligible difference for the hit you take in availability of wide aperture lenses. If you want Bokeh. 135 format is where you want to be. You can get plenty of f/1.4 lenses. With Canon you can get some f/1.2 or f/1.0 lenses. If you go Leica you can get f/0.95 lenses.

jonny1976: then pentax will come out with a 100 million camera 645z2 that will cost 8000 euro.

Due to the change in the masking on the sensor, they get a lot more noise (those masked pixels are used to reduce noise). As a result the pentax as a much higher noise floor, and the darkest couple stops is just noise and not useable information. The article states that DXO has not tested it, but having talked to people who've used it, it does not have the same useable dynamic range as the Hasselblad or Phase cameras.

gonzalu: Why is this still not implemented by default into every single camera by now? I mean seriously? I can get a FREE Android or iOS device that has FAR MORE functionality than a dSLR that costs hundreds or thousands... Bluetooth, Wi-Fi, 3G, 4G, LTE, full functioning software, apps galore, etc. etc. Why are cameras still hobbled ???

<rant mode off />

The comments about freezing were more the comparisons to phones having "apps galore." Phase and Hasselblad does have Wifi in some cameras. But they are not perfect implementations and do sometimes need the connections reset.

Because some photography jobs/gigs actually will not let you bring a radio transmitter into the shoot.

Because adding wifi makes the camera significantly more expensive not due to the electronics but because of the regulatory hoops a company has to jump through to get a radio transmitting device approved for every country they want to sell it in.

Because the same reason car electronic systems are always years behind smart phones... it's ok if your phone freezes up for 5 seconds, it's not cool if your car does. Many photographers (including myself) would be more upset if their camera froze up as often as their Android or iOS phone. So features are limited and over engineered for maximum uptime.

Because in the end most people with wifi enabled cameras never use the feature, and those that do only play with it little here or there.

Could you guys do a shootout/comparison between this and the CamRanger?

On article DJI Phantom 3 Standard photography drone unveiled (73 comments in total)
In reply to:

pdussart: The marketing of this drone is a shame.

The acquisition cost is 30% higher in Europe than in the US. Same product. This is a DJI decision. A cost of ownership of more than 1200+ USD instead of 799 in the USD.

A rip-off.

Let's wait for a Chinese copy

US does not have VAT. Individual states (and some cities) can have sales tax, but that is not reflected in the MSRP as the rate varies.

On article DJI Phantom 3 Standard photography drone unveiled (73 comments in total)
In reply to:

Sarge_: I was so hoping this would be a unit with ability to control better cameras, like the Sony RX100 units. As an architectural photographer I've been waiting for an affordable way to get a decent camera in the air, but this is still no improvement on a GoPro rig, or their other proprietary Vision cameras.

If you're reading, Phantom, I need a larger sensor for low light (dusk use) and the ability to zoom between 24mm-70mm equivalent. The camera technology and the flight tech are all there, we just need a real-time interface and controller.

I would think Phantom could sell a lot of these in the $1,500 range. Ideally they'd be software upgradable so you could fit better cameras as they become available.

I won't invest in a drone, which should work for many years, that comes with a camera that is out of date in a year or so, and which doesn't measure up to professional standards on any level.

This is not the drone you're looking for. The Inspire is a much more professional drone in terms of controls. But if you want something where you can use your own camera, you're looking for the DJI Spreading Wings line... modular design and customizability do not come cheap.

There are other drones out there by other companies and designs you can make yourself that will accept different cameras.

In reply to:

VikingPhotographer: Please stop using "Full frame" it do not give any meaning ! There are larger sensors than "Full frame"/24x36, just call it 24x36 :) Thank you very much !
If anything "new" to be made in photographic terms it´s about Lenses, it do not give any good meaning anymore to only use focal length in millimeter, far better would be angle degrees :) Then it is much easier to compare Lenses for different formats :)
Happy New Year :D

I prefer the term "135 format" as it's closer in logic and nomenclature to "APS-C format"

I have had some issues with the term full frame when I'm trying to describe a "full frame" 645 sensor vs a slightly smaller crop when comparing 40MP vs 80MP sensors.

However the bigger problem with the term "full-frame" is it implies it's an end-state... full. That's not the case. Bigger isn't always better and even if it was there's medium format and large format.

On article BPG image format aims to replace JPEGs (204 comments in total)
In reply to:

kb2zuz: Why is someone making yet another standard, we already have JPEG2000 which can save 16-bit files and no one uses outside of server applications where you want tiling and JP2 is better than a pyramidal tiff. We already have WebP which seems very similar to this standard and already works with at least some web browsers has and no one uses it.

The JPEG2000 standard isn't. There is fear that some of the libraries that leverage JP2 might have submarine patents... or at least that's how members of the JPEG2000 committee described it to me.

Edit also the patent argument is Something that has been said for 15 years... that argument may be moot at this point if the concerned patents predated it by a couple years.

On article Pentax 645Z added to studio comparison database (141 comments in total)
In reply to:

Flashback: Please, please, please put this sumptuous sensor into a compact mirror-less body.

I really don't care how much it costs!

Depends on the lens and the design. A longer focal length lens will not be as much a problem, and wider angle lenses won't have as much issue if they use a retrofocal design. However a non-retrofocal ultra wide angle may have some issues (some of which can be corrected for light light fall of and color shift) but softness may well be an issue (though some people will be find with that).

In reply to:

nerd2: Color filter in digital era? We still need polarizing filter because the sensor does not record polarized information of rays but we can simply change WB (or apply a color filter) to get the same effect.

Just a Photographer, read the description. It's a Polarizer and a Warm-Up filter in one: A spokesman for Lee told DP Review that the warm-up element of the Landscape Polariser is the equivalent to adding an 81A warm-up filter. They were asking about COLOR filters, not ND.

Yes ND and polarizers are still useful filters, but that's not the question being asked here.
