Frage von pianoplayer81:
I've noticed that neither the forum nor in the test on the built Lenses of the trees. for example, Carl-Zeiss Sonnar and Tessar, Leica Dicomar etc..
Zeiss is synonymous advertises that with your best Lenses results.
Are camcorders so smart image processor and possibly more important than the built in Lens?
Thank you for your answers voruas
Antwort von domain:
No. The lens is already synonymous still very important.
However, Zeiss and Leitz in Japanese camcorders assembled Lenses hardly actively advertise, but conversely, the Manufacturer adorn themselves with these prästigeträchtigen brand names, but I assume that all of one and the same in Japan Linsenschleiferei come.

... Zeiss advertises but synonymous with the fact that with your best Lenses results. Are camcorders so smart image processor and possibly more important than the built-Lens ... The lens plays quite a crucial role in relation to the picture, only one should not expect that the assembled Consumercamcordern "Leica" - or "Zeiss' optics to actually deliver much better quality than their counterparts of Panasonic, Sony or Konica Minolta. The big name is likely to impact more on advertising than on the picture ;-)

If you want to reflect properly (which, unfortunately, very rarely does a customer), you could come very quickly, like a Sony Carl Zeiss Lens of HC 51 (150 ¬ Camera) is not so much with Carl Zeiss has to do. What is the cost of these optics? Definitely not more than ¬ 15, the CCD and the drive should represent the main prize.
Then you look at how much original Zeiss and Leica lenses cost is ¬ 1000 upwards. Even 500 ¬ Zeiss lenses would make the Japanese suppliers Cosina build, because it is not calculated for Zeiss.
It is still like in shops (any level) stresses (Schneider-Kreuznach Samsung and Leica Zeise and stop) - the camera so that the better cards, because it is the seller, the simplest method is a client to convince.
These lenses are still better than some cheap products.
Panasonic is synonymous with the with "their" Leica lenses. It stresses - of the Leica lenses were designed and a Leica technician examines a certain number of s.Linsen suppliers.
And so it goes next and next ...
The sensors are synonymous almost all of Sony, synonymous a 1 / 8 "CCD of the new Panasonic H 80 is of Sony .....
Before you have a defective camera disposed, they unscrew, one finds other guaranteed two other components of "arch enemy".
I was the first time synonymous shocked when I use a Canon Powershot aufschraubte - Sony CCD, Casio and NEC LCD memory boards.
That is in other industries but not synonymous, like with the cars.

That you can not see so doggedly, bad synonymous Lenses have their advantages ....
see you do it differently ..... in camcorders Lenses are the cheapest low-pass.
Around 1920 on a 1 / 6 "sensor (3-chip) to dissolve, would 175 Lp / mm must be dissolved. In 1 / 4" would be still around 130 lp / mm.
Considering now that even for the Zeiss Kodak Ektar 25 color film is an absolute peak-prime with 200 lp / mm had developed, it is this material but not for long since 1999 and was the top product as regards the resolution film with Fujichrome Velvia 160 Lp / mm, so you get a sense of resolution and synonymous to what such excellence cost.
Now the lenses of camcorders a lot smaller and cheaper so synonymous. But much worse synonymous and compares it with the requirements, then you quickly see that the lens is actually limiting factor in camcorders in terms of a reasonable Resolutiondarstellen.
Looking at all now even in terms of sensor resolution and involves the Nyquist limit with them so we see that the lens actually Resolutionals by their poor low-pass filter and its essential role in the prevention of moiré occupies.
So bad was synonymous lenses have good .... only the dream of 1920 will disappear in 10% MTF at these cameras and degenerate to enable marketing tool.
And what of all this pseudo-test to see, is nothing next as electronic processing of the rough edges.
And if such a test then synonymous nor the Luma rises above 100%, one wonders anyway, in whose interest such a "test" done.
But who even a 1920 camcorder image against a 1920 picture of a good camera has, know what I mean.
It is not as "crisp" because the sharpening edges missing, but it arises from the expected image detail, with camcorder images are missing entirely.
But as long as there are people who are such a thing can turn on and marketing awards more than to leave good image quality is just something synonymous sold in large quantities .... always accompanied, of the "good test scores."
Antwort von Jan:
Thanks Wolfgang!
Now, I still found a reason why so far with their pseudo Panasonic Full HD cameras so zb the SD 100 with 3x 1 / 6 "C (MOS) more problems than the other companies with 1 / 3" or 1 / 4 "sharpness tests.
I thought it was only s.der small chips with Resolutionder per 500k effective. The slightly different sensor sizes have a larger impact on the image sharpness in conjunction with the optics (not depth) has - I was not known.

that's been years and in all German manufacturers (or, more brands?) so. Since Japan has become expensive, is in almost all countries of the Far East manufactured.
And I wonder if the Zeiss optics in the 400 ¬ of Zeiss was expected, whether or not the manufacturer, the lens manufacturer lens can offer, with the requirement "Zeiss label. And then it is expected that in the Zeiss-Labeling requirements fit. Zeiss and gets his license fees.
