yellow filter TTL M7


Recommended Posts

I search for a yellow filter for a secondhand Summicron 50 (E39) that i will buy next week.

 

Wil the M7 TTL metering correct the filter in metering?

 

It should with no problem. I used on briefly one TTL M6 and it was fine.

Please be aware that filtering can produce some surprising, and unwelcome outcomes. Your K2 filter will do well, however if you move to a red filter you are likely to find more contrast than you wish.

Is it necessary to do any exposure adjustment for a red or dark red filter?

 

In other words, if you meter through the lens, will the camera's meter be fooled by the red/dark red filter?

 

I can't recall where--or why it would make sense--but I thought I read that the darker filters could lead to incorrect TTL meter readings.

This has been my experience on my M6. I tested the light meter with the filter on and off using a gray card and even outdoor lighting. The difference was about one f-stop underexposure. Even the yellow filter was a bit off, about 1/2 f-stop. Since I normally over expose one f-stop anyway with B&W, I do not make much of an adjustment.

If you meter through the lens using the onboard meter, it will be fine. However, if you also meter using a handheld meter, you will have to mentally make an adjustment for the filter. In practice, a yellow filter makes so little difference to exposure that if you are metering externally and exposing generously, the difference will be compensated for anyway.
