Dear Readers, Is there any way of locking exposure in atuo modes without holding the *exposure lock* button pressed?. I refer to F70 and F4s. When I was shooting with a long telephoto mounted on a tripod I wanted to lock the exposure and at the same time to release the shutter using MC12A. These were to maximize sharpness. However, I noticed that touching the camera to lock the exposure, i.e. keeping that button pressed, would induce shaking. So I wish in this case there was a *sliding button* so that once pushed it would keep the exposure untill reset. Turning to manual mode will resolve the problem, yet it takes longer time. Thanks in advance /Fernando Dept. of Civil Engineering Nagoya University.
