Dear All,
thanks for replying with all the possibilities. When i tried the first Long Exposure without LENR on, i turned it on right away thereafter. As for LENR completing the exposure, that i am not sure, i waited until the image appeared on the lcd, i assumed it was done. Possibly user error.
I finally was able to contact Nikon Asia with some of the my examples. they asked if i used any filters if not then send it in for service? I wish i could without spend a bomb on filters for the 14-24mm. lol... but no i didn't.
i am based in vietnam now and i bought the camera in singapore. In order to get a definitive diagnosis/fix on the matter, i will have to pay Nikon vietnam for the service fees which kinda sucks but no choice.
If it's inherent for a megapixel camera alike, then i will live with it and use post processing as above-mentioned.
