I strongly recommend a good read on the stickied basics of photography in the newbie's corner.Finally solve the problem! Is actually the shutter.
I won't be so sure abt the 1/2 year no shopping....seen more than a couple upgraded in lesser than 1month.Finally got a 30l dry cabinet and a Siri tripod and an iPad ad card reader and a 50 mm prime lens. Probably done enough shopping for half a year!
