Hi, I bought a lens from mpb in ‘like new’ condition and there is a fabric hair within the lens large enough to appear on all photos above f/5.6. I couldn’t open the parcel until now (3 weeks later) as I was away for uni and so just discovered the issue today. Mpb refuse to do anything about it and told me to get it cleaned for ‘cheap’ at a camera repair shop but that it will also void my warranty. Is there anything I can do?
Does it actually affect the photo, or is it just that you can see it?
It’s very obvious in all photos above f/5.6. I added some photos in someone else’s comment
Ok, I looked at those. I find it hard to believe that the one thing, is responsible for the other thing. Lenses don’t work that way. A hair on the lens won’t project like that onto the sensor. This is a mystery to me. Usually you can put quite a lot of garbage on a lens before you will even notice any small degradation, and it doesn’t look like the thing that originates it.
I assume you’ve properly tested your theory and know what you are talking about, in which case, I have no idea what is going one, as I’ve never seen it work that way.
I could definitely be wrong but the hair on the lens is pretty large and the sensor looks completely clean. Also only appears with small apertures so I feel like that makes sense?
Incorrect, even a spec of dust on a lens/sensor can show up at larger apertures. Especially when shooting light colours.
On a sensor, not necessarily a lens.
