Gabriel Wilson Posted March 18, 2018 Share Posted March 18, 2018 I just purchased a new Sekonic L-858D it is a wonderful tool but I am wondering what I am losing if I exchange the item for a used meter without the cine function. I know I wont be able to use shutter angle or frame rate. Will a meter with out the Cine mode only be able to meter at 24fps? Im also curious how to check the calibration of a used meter. Thinking about the 608 potentially? Link to comment Share on other sites More sharing options...
Bruce Greene Posted March 18, 2018 Share Posted March 18, 2018 (edited) I've never owned a meter with a cine function. Just a witness mark for 1/50 sec. All other calculations I just do in my head. Why make things complicated? I do own an incident meter and a separate spot meter though. I like the calculator dial on the outside of the spot meter. It helps me visualize the readings on a scale.

Gabriel Wilson Posted March 18, 2018 Author Share Posted March 18, 2018 what about frame rate? Link to comment Share on other sites More sharing options...
Mark Dunn Posted March 18, 2018 Share Posted March 18, 2018 It's a very simple calculation, as is shutter angle. Link to comment Share on other sites More sharing options...

Gabriel Wilson Posted March 18, 2018 Author Share Posted March 18, 2018 I totally understand shutter speed and hot to calculate. I am just figuring out on a non-Cine light meter how you input frame rate? or if it is constant? Link to comment Share on other sites More sharing options...
Mark Dunn Posted March 18, 2018 Share Posted March 18, 2018 You don't input frame rate. You input shutter speed. Link to comment Share on other sites More sharing options...
Gabriel Wilson Posted March 18, 2018 Author Share Posted March 18, 2018 Right but on the cine mode versions there is also an option for frame rate. I am asking if the meter just assumes 24? Link to comment Share on other sites More sharing options...
Premium Member Adrian Sierkowski Posted March 18, 2018 Premium Member Share Posted March 18, 2018 No meter assumes anything. On a Cine Meter you enter your frame rate and your shutter angle and it calculated the shutter speed given those variables for you. If you didn't have a cine meter you'd have to do the calculation yourself and then enter that as your shutter speed. If you changed your frame rate or your shutter angle you'd have to re-calculate your shutter speed on a non cine meter. Personally, I have enough math to worry a bout that I wouldn't ever get a non-cine meter since it just makes it so much easier just to put in my FPS and shutter angle (which rarely changes). Aside, if you're doing high-speed work, you may need some pen and paper to work out a shutter speed and who has time for that? Link to comment Share on other sites More sharing options...
Stuart Brereton Posted March 18, 2018 Share Posted March 18, 2018 My Minolta meter has a cine function for a range of typical frame rates, but if your meter doesn't, then assuming that you are shooting at 24fps with a 180 degree shutter, your shutter speed would be 1/48 second. Every meter, cine or not, should have a setting for 1/50 second which is so close as makes no difference. Link to comment Share on other sites More sharing options...

Every meter, cine or not, should have a setting for 1/50 second which is so close as makes no difference. I have an older Minolta meter without cine functions. It shows only 1/30, 1/60, 1/125 etc. There is nothing like 1/70... With one exception: There is a special setting for 1/50 and it's not in the normal scale, but at the bottom of the longest exposures possible. I think this is so if it gets accidentally changed, it will change to to something like 50 minutes! And that will be so obvious, that one would not make a mistake :) Link to comment Share on other sites More sharing options...
Igor Trajkovski Posted March 18, 2018 Share Posted March 18, 2018 (edited) Almost all digital meters have couple of frame rates included,reachable either when entering CINE mode via custom settings oras in most Sekonics, after reaching the end of shutter speedscome the available FPS with 180 degree shutter in mind.The usual suggestions for different shutter angle is tocompensate with offset of the ISO.This screenshot of Sekonic's L-608© user manual explains this very clearly:While the 608 and 608 Cine both measure also FC/LUXthe newer Sekonic models offer such measurements only in the Cine variants.From what i see the difference between the 608 Cine and none Cine models is:Analog scale in 1/3 stop (vs 1/2), more fps available, selecting shutter angle,FC/LUX FL/cd/m^2 (vs FC/LUX).Best. PS: BTW, what's wrong with the Sekonic L-858D? Edited March 18, 2018 by Igor Trajkovski Link to comment Share on other sites More sharing options...
