Frage von bgk:Hi Everybody,
times because I had a question s.alle that a small HD or HDV Camera (Canon HV, and SR SonyHC, SD Panasonic, JVC HD-series and Co.) in using it:
What about your equipment with the Backfocusing, ie one can for this equipment in manual focus in telephoto Sharpen and then into the Wide Angle Switch, without the sharpness that a level "away"? In what does the zoom for you?
And when using the Auto Focus: Is the AF of your camera might "run away" the sharpness level, while you zoom or until after the zoom is finished?
Especially I would for distances between 5 and 15m of interest.
Thanks in advance for your time numerous reports of experience with the various camera types.
Regards,
BGK
Antwort von Kar.El.Gott:
SonyHVR S270 no problem
SonyHVR Z7 no problem
JVC GY-DV 5100 with no problem Fuijnon Optics
JVC HD 251 with Canon Optics enormous problems for the return of Cam led.
All tests without autofocus with Siemens star, find the switch for AF not ...
Antwort von bgk:
Thanks already for your feedback, Kar.El.. That these cameras will be little difficulty, I had already thought of me.
But I would be interested in how the consumer looks tiny. When SD was the topic hardly worth mentioning, in HD, however, seems to be different from.
Antwort von domain:
Generally, the Backfocusing actually an outdated method for mechanical zoom lenses, which are no longer necessarily be applied because there is no mechanical coupling between the focal adjustment and sharpness after the leading elements longer there, but everything only indirectly via actuators because of electronic control curves and the ev nachjustierenden AutoFocus works and that's not necessarily 100% reliable, as you know since the EX1.
Better Peaking at the focal use.
Antwort von bgk:
Basically I give you quite. The question is rather whether HD or HDV cameras generally have a problem, when zooming the sharpness level to keep (which is due at the Resolutionund small optics would be quite possible).
I have here namely a consumer camera, where the obvious is the case: in the manual focus telephoto lose the thing - for open Aperture - Zoom into the Wide Angledeutlich sharpness, so nachfokusiert be. Even when using the autofocus is the phenomenon visible: because it's synonymous blurred until the first AF after the end of the zoom restore the sharpness.
For other devices (HC9, HV30, HD6, etc.) I would not have noticed - I had these devices, but only briefly synonymous in my hands. Hence my question.
