OMD EM5 focus hold?
- Is it possible to manually pre-set a focus distance on the Olympus/Panasonic lenses, make an exposure, turn then camera off, turn the camera on and take another shot and still have the lens at the previously set distance.
You can leave the camera in manual focus and it will stay in that mode. Is that your question?
- Given that the general consensus is that the CAF system on the EM5 is less than effective, how good is the SAF at focusing on a person walking towards the photographer in a typical street scenario. I'm thinking of focal lengths of between 12 and 45 mm, wide open through to f4-5.6.
At f4-5.6, it's possible because the dof is quite large. Wider than f2.8 and for focal length longer than 20mm, it's pretty hard and I have experienced lots of misses. At f1.8 or wider and focal length > 20mm, forget it.
