I just recently bought a Sigma 17-70 but it's not the cleanest thing, I bought it for 315 shipped. I'm a total noob with this and this is the very first lens I bought after my kit lens that came with my camera.
Here are some pictures.
Do you guys know if lenspens will get rid of this mark? Can you even use lenspens to clean the back side of the lens? Or only the front? Because I never seen people use it to clean the back of the lens that goes inside the camera body.
Also there is a small dot inside the lens, will this affect anything? (I don't think you can see it in this picture, it's small white dot-like thing). I hope it's not fungus, I don't even know what the early stages of fungus look like.
