After spending 6 weeks thinking I was going crazy, Nokia have updated the phone to (among others) improve the camera. To explain: I was taking phoeots with my 920 and just thought they weren’t razor sharp. I couldn’t decide if the images were blurry or soft-focus, but I think it was a mix of both. However, Nokia have released update version 1232.5951.1249.10xx which has appeared to fix this. This WON’T change your Windows Phone version- that’s still 8.0.10211.204, it’s the firmware that changes.
Nokia don’t give much away- “Improved stability, speed and functionality for the camera”- but my guess is that the camera was slow to react, which could cause both focussing problems and blur. ? I’ll add to this once I know it’s definitely improved. The problem I’m having is that I’m comparing the images from my 920 to ones taken on my (still great) N8-00, and frankly the camera on that is just fantastic so it’s not a fair comparison.
