I am currently on a trip and I brought an 18-135mm lens and a 35mm prime as my two lenses for the trip. When I took my zoom out of my backpack off the plane and put it on my camera, I immediately noticed that all the pictures were overexposed.
I finally figured out that the aperture isn't closing. I took the lens off my camera and used my finger to manually push the aperture lever, and I found it did nothing. The aperture blades do not move.
I don't know how to fix this issue, and it's frustrating because I now don't have a zoom lens on my trip. Is there any way I can fix it myself without taking it to a camera guy?
