Frage von Benji Beutlin:
Hi,
I read again and again that when some lenses is not possible to do HD recording, (why?).
How can I tell if I have a lens in front of me, whether I use the camera to a screw can (with adapters if necessary) and then so can record HD?
thanks, in advance
friendly greetings from Benji
Antwort von Andy Garcia:
I suppose s.du thinkest weitwinkel / tele-converter before
The objective of the HDV cams are screwed.
whether what you see fit s.der quality of the image,
or from the experience reported in the forums.
So to help you the fosu.

So to help you the fosu. To the slightly more general question to be answered: optics, depending on the quality, better or worse dissolve. A WW-intent for 100 ¬ at the first viewing may very well get away: No distortion of the picture is sharp. Without direct comparisons and without test card with contrasting lines is very difficult to assess. Also, the original lens of the cameras have given a considerable scatter. Yesterday extensively tested: the Panasonic DVX 100 vs.. Canon XH A1, the latter in 4:3 SD - mode. Same monitor, same cables, same picture: The Canon provides a poor picture resolution and is lichtschwächer. Do not just resolution pixels.
So it makes little sense to save s.den optics.

I I do not know of any price range you're talking about, but in the broadcasting sector have now all 2/3-Inch-Kameras the B4-mount and you can because every B4-Lens screw it. There is no problem, a high-quality broadcast standard optics (such as a Canon 15x8) s.einer use high-resolution camera. The difference with HD lenses in most situations so low that it is not necessary for a rich sum of five or greater. Expensive it is only when you get on relatively weitwinklige recordings are dependent, because a loss of sharpness (if at all visible) at the edge of a wide-angle optics occurs.

Antwort von Benji Beutlin:
okay, thanks, the last post, I answered everything, I think times.
I went there not to Vorasatz lentils, but correct optics.
And what is with the older lenses, for example, from the photograph of the area, let's say hypothetically with an M42 thread, if I am using the adapter to a 1 / 2 or 1 / 3 Bayonet do?
Antwort von MBN:
If you look at the MTF charts anschaust your lens, you can calculate how many line pairs that thing in your chip size makes.
I did some time for the Canon L-Lenses s.einer XL-H1 calculated. The result was rather sobering: The Resolutionist better than DV, but not what would be possible with HDV.
If your M42 lenses are not absolute top optics, should the effort hardly worthwhile.
