Some problems about Sony a57

1.a57 The shooting video is autofocus. When you set the lens to MF, you can focus manually.

2. It can be set to full manual. After the lens is set to MF, you can choose A, S and M files, and when AF is set to P file.

3. framing is exposure. When framing, you can preview the effect after shooting, which is also convenient for setting.

I don't have an HDMI cable, so I don't know this function.

5. There should be. There is a wireless remote control in the flash option. As for whether the external flash is useful, it is not clear. This is unprofessional.

I've just started a57 for a week, and I'm still groping. I hope it helps you.
