The OM-4T has an exposure memory lock system to solve this problem. It can be used in both the TTL direct metering and spot metering modes. Once an exposure value stored in memory, it does not vary even if you change the aperture (or shutter speed). 38 How to Use the Exposure Memory Lock System Reference P. 109-110 The memory lock system is convenient for taking many pictures of the same subject in different backgrounds or costumes.
