After bouts of fighting with my camera, I have managed to narrow it down to either the Auto-focus motor housed in the lens itself or the sensors where the lens attaches to the body. Fingers crossed it’s just the sensors; I’m going to give them a good cleaning and hope for the best. Sadly I don’t yet own another lens to see if the problem lies with the lens itself.
Technically I could do posts with my phone’s camera, but as you can see above, the quality is not-so-great.
And just in case you were wondering, no, Grimlock has been of no help in this at all.
