RD1s sensor dust

[NorthernLights]

Hi

It's strange that when I shoot f22 and exposing for 30sec, dust spots started appearing on my pictures.

How do you clean the sensor. Same as DSLR? Switch to bulb mode, depress shutter and blow?

TCW told me it costs $45 to clean. No way...i can live with the dust if it costs $45 because any cam is going to get dust into the sensor anyway. I can clone/ stamp it away in PS.

i pretty much think that it would be a similar way to clean the sensor (as what ppl usually do for dslr)

is it dust or hotspots from the heated pixels?

Both. The heated pixels were everywhere and I needed to use noise reduction from the Epson PhotoRaw at the expense of details, to rid of the hot spots.

There were also dust particles that showed up.

icic.. guess the dust cld be already there on the sensor. only other alternative is to get a film body. else, use the old blower trick to see if u can dislodge them

You might want to invest in a wet sensor cleaning kit.

But before that, set the biggest aperture you can, F16 or F22, defocus (select minimum foces distance) the lense and aim at the sky (preferably clear) and take a picture. Then use a blower. Take another similar picture and compare to see if the dust dislodges. If it doesn't you might want to invest in the sensor cleaning kit as blowing nor brushing would help much.

This is a bigger problem for Digital RFs than DSLRs. I was shock the first time when I saw that my M8 sensor was so dirty. Blowing did not work for me at all. The larger the aperture, the more obvious the dust will be. Anyway I have tried the wet sensor cleaning kit from visible dust and so far it works rather well.

The good thing is that once you are past 500 shots the dust or grease issues starts to fade away.

Thanks JamesW and Tan131.

I hope that somehow, the dust will drop off. As for now, anything smaller than f8...it's time to practise Photoshop clone and stamping

I uses those compress air that sells in can form. So far works for my dslr and rf.

[JamesW]

I will very strongly suggest avoiding compressed air. Too many things can go wrong with using it. The design of the digital RF's protective glass over the sensor is very thin and less protected compared to the DSLR. There is also the chance of depositing dust in places that is hard to clean.

I do not claim to be expert in this matter. I drew plenty of reference from RFF - http://www.rangefinderforum.com/foru...compressed+air.
