Je ogen zien veel meer (ook door een donkere zoeker) dan een CCD of CMOS.

Valt mee, met een sluitertijd van 25 seconden had ik sterren op mijn foto..

Ligt eraan. Bij 30 sec krijg ik op 50mm strepen, 25 sec niet. dan heb ik iig het maximale aan licht ontvangen, ook van sterren die ik niet kan zien met het blote oog.

Carl Zeiss Objectieven voor F-mount

Was vorig jaar al bekend toch? Of zijn er nog meer objectieven aangekondigd?

quote:

CLN: Canon users would love to be able to use Zeiss lenses, too!
Müller: …and they keep telling us day-in day-out. So along with the ZF line, we are also introducing "ZS" lenses. Carl Zeiss ZS lenses come with the same optics as the ZF line; only the mount is different. ZS has the M-42 screw mount, the one that used to be called the "Universal SLR mount." We don't think the M-42 screw mount is going to take the market by storm, but it has a unique advantage: there are M-42 adapters available for any SLR bayonet mounts, including Canon EOS and FD. So you can adapt a ZS lens onto any 35 mm SLRs (and many other applications as well) if you crave the optical characteristics of this lens line and are willing to get along without the convenience functions of recent lenses.

quote:

CLN: And why would they prefer Zeiss ZF to Nikon?
Müller: I see two reasons.
First because they know that with Zeiss lenses they will get state-of-the-art image quality, technically and aesthetically. They will recognize that ZF lenses come with much larger rotation angles for the focus rings, like the cinematography lenses we make for Hollywood. This means that focusing can be performed much more accurately than with designs optimized for photojournalistic work.
In addition to this, ZF lenses come with a completely newly-designed iris featuring a circular shape, not those hexagons, octagons and similar geometries that give out-of-focus highlights an artificial, unnatural look. While the Japanese have appreciated this natural look for a decade or more, Hollywood has only recently rediscovered it. Curiously, it was the Japanese photo equipment makers who were mainly responsible for introducing the hexagon and octogon iris; European makers favored the circular iris until the 1960's
The other reason for buying Zeiss ZF instead of Nikon is much simpler:
Nikon just announced it was discontinuing the manufacture of manual focus lenses.

quote:

CLN: Where are the ZF lenses made?
Dr. Scherle: We develop the lens specifications for series production and the quality targets here at the Carl Zeiss factory in Oberkochen, where we also perform prototype testing in our labs and "torture chambers." The production is done at the Cosina factory in Japan under the watchful eye of Carl Zeiss employees in charge of quality assurance. The actual quality control will be performed on measuring machines designed and made by Carl Zeiss in Oberkochen just as it has been on all Japanese-made Zeiss lenses.

quote:

CLN: And how will they be priced?
Müller: ZF lenses are precision tools, not luxury items. They should be in reach of demanding photographers and should be economically justifiable for pros. Likewise, for industrial applications like machine vision, pattern recognition, process control, advanced robotics, and quality assurance, prices cannot go through the roof, since lenses are usually not purchased as single units, but in quantities of 50, 100, or even 1000 at a time.
Dr. Scherle: By the way: This is why we have them produced in Japan. Thus we can achieve the price level that Nikon customers all over the world are used to.

Als ik het goed begrepen heb komt er een Kodak-sensor in ter grootte van 45x34mm met 18MP. Dat zal neerkomen op een cropfactor van 1,3.

quote:

In an interview with a senior Pentax executive, the following details about the new Pentax DSLR have emerged.

1. 10mp sensor

When asked whether it will be the Sony sensor. No direct confirmation that it will be. The answer is that there are a limited number of makers of large sensors so there will be no surprises on the sensor supplier. So the possibility remains that it could be a Kodak sensor.

2. anti-shake

The new camera will have anti-shake, but there is no detail whether it will be in camera or in lens

3. K mount

The K mount will evolve. New functionality will be added but backward compatibility is preserved.

4. Improvements over the *ist D series

New DSLR is aimed at the semi-pro. The new camera will have higher top shutter speed, higher continuous shooting speed, and high sensitivity (similar to current D series) but it will preserve the Pentax heritage of light weight and compactness

5. Partnership with Samsung is to procure electronic components cheaply without bearing the risk of starting up factories to make these components in house. Pentax also plans to develop large image sensors with Samsung but there is no completion date on that collaboration.

6. "...our biggest asset is our unique lens lineup. The final picture is the combination of a whole system, including the lens and I beleive that is our strongest point."

7. Concerning the 645D

"We are self-confident as the camera manufacturer which knows the market of 645 formats well."
