GREEN SCREENS 4 HALF BY 5 FT MANUAL

In addition, most lenses are sharpest two to three stops down, although I haven't used this particular lens.

Everything within your distance range should be sharp enough for 4k video.

GREEN SCREENS 4 HALF BY 5 FT MANUAL

Stop it down two to three stops (f6.3 to f8), set the focus about 1/3 of the way back from the front edge of your capture zone, and it shouldn't matter that it is manual focus. On the other hand, any 8mm lens has a LOT of depth of field (the distance between the nearest and the furthest points of acceptably sharp focus), even wide open (at f4). They might also be unacceptably distorted when close to the camera, although I think 5 feet will be far enough away to avoid the worst of that. This means that the subject will change size noticably as they move towards and away from the camera. Thank you for any info and direction you can give me.ĭumb question - are you shooting sequences of stills or video? I'm guessing video, but want to be sureĪn 8mm lens has a pretty wide angle of view (about 95 degrees horizontally). Am i wrong with thinking i will needed auto focus for this ? At times the camera will be 'un-maned' and needs to hold a focus with the subject walking around, roughly 5 foot from lens then to a distance of 12' away, along with side to side motion. I was looking at the SLR Magic 8mm f/4 Len, but dont think the manual focus will work for me. Im looking to spend 750-1,000 for the two lens. In the near future i will be getting a GH5 and plan on starting with two lens, one for the green screen and a second for 'run and gun' around town and nature footage from the woods/forest.īeing on a budget i would like to get a native 4/3rds lens as i do not have enough money for two lens along with a speed booster/adaptor. The subject will be walking up and down the length (roughly 10-15 foot) and side to side as much as the frame will allow.Ĭurrently im using (please dont chuckle too hard) a Panasonic HC-V720, mounting it 'sideways' (portrait view ?) to try and gain as much 'run way' as i can. The green screen is 10' wide, hangs on a 8' wall and then rolls out/down to cover most of the 20' length of flooring. Im looking for info on a lens to shoot green screen in a 20x15 sized room.

As you will see im new photography and film, so sorry for naive questions.
