Hello everyone, Ive never posted on a forum before so please bare with me if i'm not doing this correctly but i really could do with some advise regarding a problem I encountered on the weekend. I used my speed light on top of my Nikon and unfortunately at least 50% of my photos are out of focus and i have no idea why. My shutter was set on 1/80th or above mostly 1/100. It was a very dark rainy /cloudy day so my iso was very high but i used shutter priority so it never went below 1/80. Could it be the lens i used ? a 50mm? Hopefully someone can tell me what i did wrong so this doesn't happen again. i am so confused because some of the images came out clear and then on the same settings the next image would be out of focus? Please any advise would be appreciated! I have added an example of one image.
