    ISO: 200
    Exposure: 1/320 sec
    Aperture: 6.3
    Focal Length: 300mm

    sharpness could be improved by increasing shutter speed to reduce hand-shake blur

    image looks out of focus, rather than hand shake blur.

    @ 300mm, I normally try to keep shutter at 1/500-1/800 especially when subject is on the move. Not sure how confident you are with the ISO performance of your camera, but I will bump it up to 640 or 800 ISO and use manual exposure to track such subjects. 300mm f6.3 @ ISO 200 is a bit too challenging to get good handheld shots, not that it can't be done, but maybe can explore better options. In addition like what the previous bro said, the focus was not locked in on the subject.

    My 2 cents

    I think the guy was saying "Hey what the hell man, why are you taking a picture of us without our permission?" Did you ask them whether you can publish their picture here or anywhere?

    sg doesn't require that. you can feel free to do so as long as image is taken in public space.

    agree with you, bro. 1/500 would be more comfortable. thkq for the advice
    btw, dont quite understand what you mean by "using manual exposure to track"

    the smile on the lady's face seems to say otherwise.
    They didn't seem to mind, we walked passed each other after the shot. Thanks to them

    If you notice, they are walking along the road with uneven lighting due to shadows from the trees. I will not wanna overexpose or underexpose the whole scene in this situation as the meter could go against me in Av mode. So i will wanna meter the surrounding and keep the settings fixed. Here's what I will do, e.g set shutter at 1/500, f7.1 or f8 (stop down a bit for sharpness) manually, and lock and press shutter when the ray of sunlight hit their face.

    I know this is am impromptu shot, and you may say "where got time to do the metering" Trust me if you do it often enough, the settings will be at the tip of your hands and you can set it very fast.

    actually i realized if you crop away the man, and leave the woman, you got a little sharper picture, less distraction, with some kind of eye candy too (not for me though)
