Hi everyone.I just purchased an external flash for my camera and it has added about and extra 400grams weight and now my right hand is cramping because the camera grip is small and seems to be putting all the weight on my wrist....I have pretty small hands too...Just wondering if anyone else has a problem with this also? The d3100 isnt an overly big camera and just feels hard to grip it properly...I was thinking maybe a battery grip would help...Or if anyone has any suggestions? Thanks in advance for anyones help
