Frage von Natevi:
Hello Forumlinge,
when adjusting the cutting width is a situation I have noticed the need for a clarification: When I use the Lens RESTRICT so that both the max telephoto range as synonymous in the max. Weitwinkelbereeich sharp density, is a very distant object if the focus on infinity getellt is blurred. The focus is then up
to the Infinite - stop. Is this normal?
Besten Gruß

Antwort von Markus:
Is this normal? Yes. The focal length setting for infinity fit perhaps for wide-angle shots, but the more you are in the telephoto range vortastet, the more you can see which image-level focus actually is.
The universe is infinite - or at least some scientists believe. ;-)
Antwort von Natevi:
Yes, thank you for the quick reply,
the completeness will then still the Lord Einstein quote (after the steep template)
"There are two things are infinite, the universe and human stupidity. The universe I am not so sure"
Best Regards
Diethelm
Antwort von robbie:
yes, as I said, the objective to touch goes to infinity only in the wide area. and this is all so better optics. is clearly yes. infinity is not defined, and if something 100m away, it is nevertheless not infinitely removed. remembers only one in this area differed weitwinkel not.

@ Diethelm
... because the normal every cameraman course the sweat on the forehead and pushes we normally do not object in space film, we have given the facts amount to a adjustable mechanical stop s.Schärfering installed.
Thus, the cameraman synonymous an endpoint in the "worldly" distances and shift the focus to "infinity" at least ends in sharp area. Everything else with the universe and so far is of any practice.
Antwort von Natevi:
It looks so difficult to Wolfgang from the last answer ;-)
How do you have to do that?
Would you ever shut image of it?
Is that what you are times as a "crooked Zoom have described?

Antwort von przy:
nee, that is still something else ... The precision engineering for the Unendlichanschlag is a small set Alustück with a grub screw ... failing that, against a small knurled exchange. Because neither the viewfinders, even in the Monitörchen you can really see the sharpness. That is why it is annoying not to have Unendlichanschlag.
Picture hab'ich unfortunately none. The "Made" was actually planned, once differ-wide (very wide) objects s.Endanschlag feinstellen them. But is rarely done.
The phenomenon is way, with the quality of the lens rapidly ... 16er at the Canon models, the effect almost absent. This is s.den refraction values of the different glass types and the curvatures because the Bikonvexlinsen, the beam deflection for the focus of a package already s.der first lens and good lens Lenses have forms in which the crushing forces of different radii evenly distributed .... etc. etc. etc.
But stop with enough mediocre lenses.!

aaaaachhh always this eternal login ....
Antwort von Natevi:
Is not necessary to login,
Writing style and content are enough business card ... ;-)
In this sense
a friendly greeting
