Hi, I'm new to photography but I just got a Mamiya NC1000 with a Canon D mount manual lens. The e-bay seller said it was mint but when I got it it had fungus inside the lens. I was told it would be cheaper to get a new lens than to try to fix it.... I've put a roll in a snapped some shots to see if the fungus shows up on the pics (I was told most likley it will)...it is more like a haze condensation fungus combo... Also it has light metering but the needle is always way pass the numbers on the scale. I was looking to get a new battery in the unit. I originally purchased this just for the lens so I can use it for another project but I really like the camera and want to use it. What other lens options are out there for me. I did a search to try to find the Mamiya CS series lenses but not much came up.... Thank you in advance.
