The sensor is clean using my 50mm Summilux. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! The instructions for Dust Detection are to stop down to the largest (“f/16 or f/22”), defocus and take a photo of something with no detail (I shot the sky). I ran Dust Detection again. If I only stop down to f/16 the specks are not visible. If I stop down one or two clicks more (the lens goes to f/22), the specs are visible again. The Summilux only stops down to f/16 and the specks are not visible. Link to post Share on other sites More sharing options...

rmcnelly Posted February 3, 2022 Share #82 Posted February 3, 2022 After examining the sensor with a magnifier, I believe it is dust or specks on the sensor. Link to post Share on other sites More sharing options...

Nigel_Meaby Posted February 8, 2022 Share #85 Posted February 8, 2022 (edited) I hope this is allowed. I've started a group on Flickr for this lens, as there wasn't one, so I invite everyone to join and add their images. I just bought this lens so will add some images here soon, too.

wizard Posted February 9, 2022 Share #95 Posted February 9, 2022 Am 3.2.2022 um 17:27 schrieb rmcnelly: I’ve cleaned the rear element with no change. Seems to be internal dust. Internal dust will never ever cause such clearly defined spots on the output image. You'd be surprised how much internal dust may accumulate in any given lens before you would even have a chance to notice it. Large amounts of internal dust will cause a certain reduction in contrast, but that is hard to detect as well, since you would need a dust-free lens of the same type to compare with. 1 Link to post Share on other sites More sharing options...

It is dust on the sensor, not visible at f16, only at f/22. Link to post Share on other sites More sharing options...
