Josh Marino Posted September 22, 2015 Share Posted September 22, 2015 Hello, I am capturing high-speed videos of water droplets using a PhotonFocus TrackCam (C-mount), capable of 1000+ fps. The lens I was using was a Computar 18-108mm/f2.5-16, that was lying around. I was able to have decent focus for one droplet (diameter of ~1 mm), but was having trouble getting a DOF for multiple droplets close together, shot from a little over a foot away. What lens would you recommend to use in order to have ~5mm DOF with a magnification of 1-2X? The lenses I have found so far online are either capable of doing one or the other (DOF/magnification), but not both. {I am already lighting the scene for 1000+ fps} Any help would be appreciated, Josh Quote Link to comment Share on other sites More sharing options...
