First time user of any forums. If this isn't the place to ask questions and get advice, I apologize in advance. I have a NEX 5 and more recently an a6000. I bought the 6000 because of its higher resolution. I have some basic questions as follow: 1. I use DMF along with AF-A focus to bring a specific object into sharp focus (using the focus ring) with the shutter halfway down until focused then press the shutter the rest of the way. If I let up on the shutter after focusing at the half way mode and then press it all the way down does the specific object remain in focus? Even if I shift the camera to a different angle? Do I need to use AF-C focus? I guess what I'm asking is once you bring something into focus the first time, will it remain in focus for subsequent shots, i.e. bracketing using shutter priority and aperture changes? 2. I bought a simple Remote Control ($10) and it works great. But It isn't capable of doing a half-way down shutter to wait for auto focus to finish. The test shots I've taken all look identical compared to manually using the shutter. But I don't want to take a field trip and come back finding that the focus has been compromised. I see that Sony has a more sophisticated remote for $30 but the reviews aren't good (?). Appreciate any feedback on these topics.
