35mm Adapter - unscharfes Bild

35mm adapter - Picture blurred



Frage von Manuell:
August 2010

Hi,

I now have a sgBlade 35mm adapter. No matter whether I with a 50mm Lens, 28mm Lens or movies, s.ca. 5 meters distance to the object can not be focusing more of this.
Does anyone know this problem?

Camera is an HPX171, zoomed to 83 and sharpness to 34, if someone has the same combination.

Also in the field below 5 meters can the focus shift perfectly and focusing the desired object.
Am I as a fallacy? Do I need another lens?



Antwort von Axel:

You have to adjust the flange. Without first investigating the camcorder-focus lens by clicking on the grain size of the stationary ground glass (possibly with Peaking) Focus (Here either the middle or the edge sharp, but not both, of the achromatic sgBlade least slip, but perhaps synonymous an inappropriate filter for your thread / lens). If your camera allows you to save this focus!

Then: On the adapter (based on the Letus) there must be a marker that indicates the position of the focusing screen. From there, Align a tape measure with a Siemens star
After the adjustment you check again the correct flange, adding the camera on a distant church tower or minaret and s.Lens judge on """ place. Is it sharp, you've done it. Is fiddly and annoying, not a matter for the impatient or Coarse motor.




Antwort von Manuell:

Hi,

yes thank you. The first part of your instructions I have of course made. Then again, the tests very well with tape measure, because it will certainly not fit, so lens is set to 1 meter in real well then, a distance of only a few cm. Then I'll fiddle there again :-)
