toggen Posted March 2, 2012 Share Posted March 2, 2012 Hi! I have followed the setting suggestions from the GH2 - book, but how do i compensate /change exposure when i use a manual lens, i don´t want to change the aperture on the lens. I really want to use the scroll wheel in the "display button menu" + - 3 steps, but it is greyed out.. Prob. a very easy thing this stuff, but please, help! Thanks, T Link to comment Share on other sites More sharing options...
Sara Posted March 2, 2012 Share Posted March 2, 2012 Three things control exposure. Aperture, Shutter Speed, and ISO. Basic basic photography / videography. So if you don't want to change Aperture you are left with 2 options. And when shooting video you usually want to use the 180 degree rule, leaving your shutter speed 1/50th of a second (for 24p shooting) for optimal motion. So you are now left with one option....iso! The + - 3 EV options are greyed out for a reason. Link to comment Share on other sites More sharing options...
RobD Posted March 2, 2012 Share Posted March 2, 2012 If you are using a manual lens you have no option but to operate focus and aperture manually. If you mean you do not want to adjust the aperture then the only other methods are as already mentioned ISO or use a variable ND filter.

Sara Posted March 3, 2012 Share Posted March 3, 2012 [quote author=toggen link=topic=352.msg2150#msg2150 date=1330723239] Got it. thanks to all! Too bad,really - having to plunder around with filters.. [/quote] ...like every other professional shooting movies for hollywood? It is part of film making. Filters cut "some" sharpness but they are a needed accessory when controlling exposure or for creative flare or softening effects. Heliopan make a good Variable ND filter for your lenses - costs around $250. If you have a good matte box you can use 4x4 or larger filters and stack them quite easily. Have fun!

Sara Posted March 3, 2012 Share Posted March 3, 2012 if you are in the US , lensrentals.com is cheap and reputable for lenses, filters, matteboxes, and tons of other gear. Lots of fun! Link to comment Share on other sites More sharing options...
jean-baptiste lefournier Posted March 3, 2012 Share Posted March 3, 2012 If you don't want to buy a very expensive filter try [b]LCW ND FADER MII[/b] (around 70-90 $) Light Craft Workshop ND FADER are really good, it's really "Neutral" density, I tried GENUS ND Fader and they have color casting issue. All Vimeo gurus have recommanded it (Like Philipp Bloom did) Link to comment Share on other sites More sharing options...
