Canon 1014xls Prism Exposure Compensation

Post by **rtsquard** » Tue May 11, 2004 9:07 am

Has anyone worked out the necessary exposure adjustment for the reflex prism in a Canon 1014xls when using an external lightmeter? I have only seen general references to adjustments in the range of 1/3 to a full stop for the prisms used in Super 8 cameras, but no specifics.

Thanks for any information.

I would simply use the internal meter as my starting point and then calibrate the external meter accordingly.

Right, like take a gray card reading with the internal meter and compare to your external reading. I also got a 1014 XL-S recently and I'd like to hear about your findings. It's possible that the internal meter is calibrated for T-stops and they'll come out the same.

Super 8 cameras always read in T-stops. It's at the back end of the equation. That's one of the beauties. The task is to learn the bias of the camera you are using.

The 1014XL-S meter is also one of the best. I wouldn't need an external light meter. On my first roll, I set mine on auto, with K40 and one old 650watt 3400K movie light inside my house. It came out looking lik a 35mm movie clip. Not very close, but defeintely excellent for a home movie. 8O

The 1014 XL-S shows F1.4 in the internal light meter. I realize the lens is rated at F1.4, but the eyepiece prism would still cut additional light. Perhaps the internal meter gives T-stops for the lens but doesn't account for the prism.

I believe a T stop is a T stop is a T stop. If it gets 1.4 it shows 1.4 and could well be rated at 1.4, but the rating is secondary. What it gets is what it shows.
