If you ever want to know how many pieces of dust have landed on your sensor, a pinhole lens is the quickest way to see them all. 🙂 I did think of that, but took it out of my reply because I was thinking that anything on the sensor would be in-focus regardless of what the lens was doing. Maybe I'm wrong though, not sure.. Link to comment Share on other sites More sharing options...

Maybe I'm wrong though, not sure.. You'd think so, but no! If you're using like an f/1.2 lens, you can have surprisingly big dust spots on your sensor and never be any the wiser. The more stopped down, the more they appear. From what I remember, and I might be wrong about this, it's bascally the same effect as using a large diffuse light source vs a small point source - put your hand next to a white card near the large diffuse source and you'll get a blurry, indistinct shadow. Do the same with a small point source and you'll get a well-defined crisp shadow. It's the same on a smaller scale with sensor dust. kye 1 Link to comment Share on other sites More sharing options...
eatstoomuchjam Posted 1 hour ago Share Posted 1 hour ago The camera is here. As far as I can see, there is a single decent-sized piece of dust on one of the internal ND filters and that's it. I cannot see any other marks on the camera's sensor assembly. The speck is big enough that I could imagine it being a little bit visible on a big blue sky, but in a way that'd be not hard to clone out. I'm also going to have to experiment with shaking the camera a little bit and/or blasting a rocket blower into the vent holes/fans. It's hard to imagine how that little sucker got in there. Worst case, if I decided to send it to CPS, I have to assume it'd be a pretty cheap repair. Overall, I'll gladly trade that for the $1,500 price reduction vs new. 😅 Link to comment Share on other sites More sharing options...
