On article Nikon D7200 Review (640 comments in total)
In reply to:

SungiBr: It's strange that people are praising the -3EV focus capabilities of the D7200, but forget to mention that Pentax already done that, two years ago with K5II and K3 after.
Of course I'm not that ingenius to think the AF performance of K5/K3 are on par with Nikon in every aspect, but they at least could point that it is as precise and sensitive.

Only corrupt people buy Canikon, the companies that steal innovations from other camera manufacturers like Pentax and Olympus, congrats on being one of the stupid sheep who does what they're told. It's people like you who are responsible for keeping corrupt companies in business, just like Microsoft, Apple, Google, Verizon, Intel and AT&T. Sony deserved to get hacked, just like these companies do. At least Pentax weatherproofs most of their cameras. And both Olympus and Pentax have pixel mapping built in.

I really like that they made it weather sealed! Is the lens threaded to take filters?

alexisgreat: I love my sensors bare, no filters allowed. That means no Bayer, no AA, no IR/UV cut filter. I add filters as I please, whether they be for narrowband imaging for light polluted areas or broadband color imaging or even UV or IR imaging.

I hate how manufacturers decide whats good for us and they add the filters "built-in" and cater to the lowly masses. I like building my own computers, telescopes, and cameras. It's how you LEARN. No wonder society is being dumbed down- no one likes to innovate anymore.

A camera IS a computer, just like a cell phone is a computer, people just dont like to admit they are technogeeks. All of the above have CPU, memory, chips, etc., they are ALL computers.

In reply to:

paulfulper: The best SUPERZOOM I'm waiting for is....
6.6 x 8.8 sensor , twice the size of all the other superzoom
backside illuminated CMOS
24-2200 zoom.
5 axis stabilization
full manual control beside the automatic
hot shoe flash and pop up flash
4k video
without RAW , NFC and WI FI to lower the cost ( I don't need them )
$1.200 us
That's my dream

Cant you do what telescopes do and merely use barlow lenses to double the focal length? Or just do afocal photography and couple your camera to your telescope. Small sensors have the advantage there (faster f stops)

uh except there are ways around the speed of light limit by warping space (alcubierre drive) or via traversable wormholes (see Kip Thorne, theoretical physicist).

alexisgreat: I'd like the ability to pick my own sensors, lenses, filters (or not) as I please and build my own cameras. Just like one can pick their own cpu, motherboard, video card, memory and peripherals and build their own computer.

I guess my chief issue is having to buy a new version of Photoshop every time I buy a new camera so that it can read the new RAWs. But there are other options like Raw Digger, Lightroom and others.

I have a mono camera that I use for astrophotography, it doesn't even do RAW, it does something else called FITS and there's a free plugin available for it to use in Photoshop called FITS Liberator. I also use Fuji cameras which have EXR sensors (also not Bayer, enhanced dynamic range.)

Do you think it would be good idea if camera design and also RAW was standardized across the board?

Having a scientific and flexible approach to photography is extremely useful. You can buy filters as you need them, I hate having to remove inbuilt stuff. I also build my own computers. In both cases it's a great way to learn how things work instead of brainlessly using them out of convenience. That's why I also loathe cell phone cameras- although they do serve a purpose of making sure authority figures dont abuse their power and they get documented with visual evidence if they do.

Lassoni: B&W only ? Not very practical

You can get excellent color images by using color filters with this camera- way better than Bayer fakesterism

In reply to:

falconeyes: The difference in base ISO between the Typ 246 (Monochrom) and Typ 240 allows an interesting estimate of how much light the Bayer filter blocks, on average for white light.

It is ISO 320 vs. ISO 200, or 0.678 or 2/3 stops.

Part of this is due to the fact that not all green, red, blue esp. is weighted equal by the human eye. I.e., one must discard some photons to emulate the human eye's color vision (as one must discard all photons outside the human's visibility spectrum). Which means it can't be avoided in a color sensor. This should be the reason for the 2/3 stop difference above which probably is the difference in sensitivity between a green and a white sensel.

But another part is due to the fact that e.g., only half the pixels in a Bayer sensor receive green.

Both effects combined mean that an optimized sensor design which discards as few photons as physically possible, may be about 1.5 stops better than Bayer sensors.

A DxO test of both cameras may give us precise numbers.

Wrong falconeyes. Even physicists like Kip Thorne and Brian Greene have admitted that civilizations just a few hundred years ahead of us would have mastered wormhole space and time travel and that our level of scientific knowledge compared to such an advanced civilization is like comparing us to an ant. Seems like you think too highly of humankind and suffer from the error of hubris. We are closer to cavemen then we are to harnessing nuclear fusion so dont think so highly of 21st century humanity.

To those who doubt that mono sensors are better, obviously know little or nothing about physics. Of course they are better! Why else do astronomers (even us amateurs) use mono LRGB imaging. Bayer filter fake color imaging is only for those who are just beginning. Anyone who values image quality above all else images with LRGB, not only is the resolution much better, but exposure times are also much less! A Bayer filter can be removed from any sensor by simply scratching it off- there are a few tutorials online, look them up.

Anyone doubting the real advantages of mono imaging with color filters needs to look up LRGB imaging. You'll ditch Bayer forever.

Mike FL: Leica M makes FUJI lot of thinking for next X100 such as:

- Change the location of OVF/EVF switch?

- The aperture ring?

- Make the ON/OFF switch as ON/OFF-Driver mode combo?

- take the grip off (wait, it needs to ask Leica why M never has a grip)

- a BW edition?

FUJI's X100 team is getting headache for next X100's look.

NO?

BTW you can remove the Bayer mask off your CCD, you just need to scratch it off. It's a simple process, look it up online.

look up LRGB imaging with mono astronomic CCD cameras. Much better resolution and much lower exposure times. Stop using the Bayer filters with its pretend colors.

In reply to:

Stephen Williams: There are many claims here about the superiority of a monochrome sensor over a color sensor. Could someone please supply a reference (URL) where there are samples showing direct comparisons of files made under controlled conditions?

It's pretty obvious that mono sensors are much better than false color bayer sensors, just ask an astronomer why they use mono cameras with color and luminance filters (LRGB imaging) over these dumb bayer filtered false color sensors you guys use. Not only is the resolution MUCH better, exposure times are cut to 1/4th!
