Panasonic must catch this serial killer...

Seriously, I doubt it has a fluorine coating, given fluorine is a gas.
Nitpicking.

ThatCamFan: Or just use a polorizer, mit is wasting time.

Actually It's not 45 degrees as I said, but Brewster's angle. Read the wikipedia article.
Sorry to Virvatulet, I didnt see your post.

Mal69: I just use a multi coated B+W polarizing filter, when turned the right way it eliminates those reflections, alternatively if the picture is very important i use my superpowers to levitate outside the window while i take the shot.

I think this will be good for all those camera phones of which there are tens of millions around the world.

Wrong, totally wrong.
You should read the article on Brewster's angle in the Wikipedia.

Light reflected from glass is mostly polarised when it is reflected at 45 degrees,
but if it's from a window straight in front of you a polariser has very little effect,because the reflected light is barely polarised in this circumstance.
Why dont you just try and pull out a polariser and try it right now?

Great Bustard: Oh yeah? Well, uh, Nikon has oil spots on their sensor. And you know what? They had oil on their sensor long before Canon had these dots. So, well, like, there. Take that! : )

The Canon 5D had oil spots on their sensors long before Nikon.

digiart: Very informative article. It explains very well what we know from experience. Thank you!

P.S.
It would be excellent if in the reviews DPR tested each camera to find out what is the ISO setting that gives you the best dynamic range.

The best dynamic range is generally the lowest ISO (but not quite always, sometimes it's the second lowest).

yesman12: When I see innovation like this, it confirms the reason I went with In Body Image Stabilization... Much more innovative and extensible than In Lens. And all the noise around In Lens being better is probably a wash at this point. In lens is a hold over from film era. Look what In Body can give you....

- Image stabilization on all lenses.
- Tilt shift function on all lenses up to a few degrees.
- Astrotracer in body equatorial mount (and I have used it)
- Macro adjustment
- Configurable aniti- Alias filtering
- And now increased resolution (I am sure off tripod will follow).

Where as In Lens only provides IS on a given lens. That is it.

I am most surprised by your statement that there is a tilt shift function. As far as I know there is shift but no tilt.

The hi-res mode is definitely sharper than the D810 if you look at the etchings.
And less moire.
Didnt Hasselblad have a similar mechanism where it moved the sensor and combined the images?
I would love to see other manufacturers offer this feature.

Wye Photography: It will be very interesting looking at sample pix from all over the zoom range especially at the long end. Will I laugh or cry or both!

An ideal camera for pedos, it's bound to sell well!

The first thing that came to mind was taking pics of small birds.
I'd like to see how the moon comes out with this lens.

ProfHankD: This is one of the few ways in which small sensors can still win. The camera's lens is huge... until you compare it to other lenses approaching 2000mm f/6.3. My closest FF lens is a 1250mm f/11 mirror lens; it could swallow about 4 of this camera, and it produces bokeh full of doughnuts. On the other hand, the sensor here is around 5.6X crop factor, which means the lens focal length range is really about 4-350mm... which explains why it is so much smaller than my mirror lens. Of course, that is still an awesome optical achievement: a typical 70-200mm f/4 FF lens is bigger than this lens. The price is also impressively low.

In sum, this seems like one heck of a versatile camera for the price. On a pan/tilt mount, this could be an amazing security camera. It probably is fixing a multitude of optical sins in firmware, with IQ suffering somewhat, but it's still darn impressive.

What brand mirror lens has a focal length of 1250?
Just curious.

tkbslc: atmospheric distortion + haze + diffraction + camera shake = FANTASTIC PHOTOS!!!

Yes, I noticed haze and diffraction with my Nikon 1000mm mirror lens.
But at reasonably close distances this is less of a problem.
As for camera shake, I wonder if a tripod will be a necessity.

Gotta love Nikon Marketing.

Better than inspired photos with flare.

Hopefully this could be implemented with any camera that has a sensor cleaner that uses shake, providing the control of the movement can be made fine enough.
It's only of interest for the photography of static objects.

I actually thought of this a year ago, but then I wondered if the curvature would not need to change according to the lens. So it might work very well in a compact camera with a fixed focal length lens. In any case technology always involves tradeoffs.
Maybe Ricoh's idea of changing the sensor with the lens would be the rihgt thing here.
I hope they cant patent the very idea of a curved sensor.

On Nikon D4s First Impressions Review preview (1042 comments in total)
In reply to:

amandl: Nikon D4s - why this gadget sucks!
I bought a D4s..took my first shots (RAW)- no chance getting them into Lightroom (latest ver) in a propriet way. Converting them to DNG and doing an import is not an option... OK why should Nikon sent any information to companies like Adobe for changes in their RAW specification. All real pros are using Nikon software - that seems to be the thought at those japanese Productmanagers..
ok so far - I've to wait till Adobe has done the reverse engineering to geht the changes in the format...
2nd why buying a new released model is no more option for me was - I put the Pocketwizard mini TT1 onto the D4s. switched on the Flex TT5 receivers (all on latest Firmware) triggered the Cam in higspeed mode since I had to do some higespeed shootings and... the flashes where only triggered at the first shutter release... Answer from Nikon Support: not compatible... and 3rd party product... not supported... so that's why I can say the D4s is a useless pice of rubbish!

Your rant reeks of anger. Not very objective.

These kids will end up being unable to cope in the digital world!
Just kidding.
