PatrickV Posted November 8, 2012 Share Posted November 8, 2012 Hi there, I'm the owner of a GH2 and today i purchased a SLR Magic 12mm lens. I saw several movies of this combination (GH2+SLR Magic 12mm) and i was surprised of the quality. I tried several locations today, but the image quality is not sharp. By filming close objects my 14-140 mm lens is even sharper. What do i do wrong? Is it because i do not use a viewfinder or something?[list] [*]I'm not using a follow focus, viewfinder or external monitor [*]I film in the HBR mode, 160 ISO, Shutterspeed 1/50 [*]Manual focus (ofcourse) [/list] Hope to hear from you guys!

QuickHitRecord Posted November 8, 2012 Share Posted November 8, 2012 A monitor with peaking will help you nail that sharp focus a lot better than the GH2's viewfinder or LED screen will. If you're concerned about having a problem lens, I'd suggest composing an image with multiple subjects at varying distances, putting the lens in T1.6, and then capturing a rack focus from one extreme to the other. You'll know right away when you watch it. Quote Link to comment Share on other sites More sharing options...
PatrickV Posted November 8, 2012 Author Share Posted November 8, 2012 I don't think the lens is broke, but i think i am not getting the max. out of it. Check this Vimeo link for some footage of my SLR Magic 12mm: [url="https://vimeo.com/53087375"]https://vimeo.com/53087375[/url] My 14-140mm lens could do this... :mellow: Quote Link to comment Share on other sites More sharing options...

galenb Posted November 8, 2012 Share Posted November 8, 2012 Okay but you have to rack the focus so that there is always something in the scene that is in focus. Take a ruler or measuring tape and place it extending away from the camera and shoot down it. As you shoot, rack the focus back and fourth slowly. There will always be something in focus and you'll be able to judge it better. Quote Link to comment Share on other sites More sharing options...
zaz Posted November 9, 2012 Share Posted November 9, 2012 by rack, galen means slowly turn the focus ring from one side to the other, then back again. your lens is fine. it just needs to be tweaked a little more when composing the shot. also, if you close the apature down (1.6 is wide open), more stuff will be in focus.

PatrickV Posted November 19, 2012 Author Share Posted November 19, 2012 Thank for your help guys. I did a new test outside. Settings were: HBR mode ISO 160 Infinity focus Aperture F.4 What do you guys think? [url="https://vimeo.com/53837699"]https://vimeo.com/53837699[/url] It also seems that my screen is not as wide as it supposed to be. This lens should be a very wide lens, but it isn't wide at all. Do i have to adjust my settings probably? Quote Link to comment Share on other sites More sharing options...
