I just wanted to know if anyone else was getting huge amounts of spots on their D7100 sensor?
It has been about 4 months since new. I have done a lot of shooting. There are about 60 spots that I can count on the sensor. Some spots are hard edged, some are soft (like oil) (different lenses, different pictures, same spots)
BTW these spots were found using the enhanced spot healing brush in Lightroom 5.
After about 2k shots, I noticed about 7 spots on my D7100 at f/22. Not a problem: I just wet cleaned the sensor using the kit I bought from Copper Hill. I tried a rocket blower first, but it didn't get all the crud. The wet cleaning is easy if you follow the directions on the Copper Hill web site. There are also a fair number of other cleaning kits/methods. One caution: make sure you have a fully charged battery before starting the cleaning process; you wouldn't want the shutter closing and the mirror dropping while you have a cleaning swab in the mirror box.
After about 4,000 images, I noticed some spots in the sky of an HDR image. Checked the sensor using a sensor loupe and had what appeared to be about a dozen oil splatters plus some other debris. Wet cleaned and all is well so far after another 2,000 shots. I change lenses quite often and thus am prone to getting whatever on the sensors of my cameras and found that wet cleaning is the way for me to go.
I had spots on my sensor also. Took it in to the camera store where I bought it from and they cleaned it for me. Took them about 3 tries to get it cleaned. it was really noticeable on the sky shots. I do a lot of bird photography and couldn't believe I was getting spots so soon on my d7100.
Interesting. According to these new machines in Nikon occurs more often in the "oil" problem? The D600 has this problem. Now I can hear anything that paint a dusty mirror shaft. I do not know what the truth is. If you live often shift lens to understand the effects of dust. Try to pump blow out the dirt.
Peter, I probably do 85-90% of my shots with one lens, so I don't change it too often. But, I do switch lenses occasionally. I am conscious of the time the lens is off and try to shield the camera as much as possible and put the next lens on quickly or put the cover on. Now most of my lenses and the one I use the most is not an IF lens. I may be bellowing dust into the camera with the lens.???
BTW the oil seems to be primarily in the upper left corner of a landscape frame, though there were other oil spots in other areas. In my case, most of the spots were dust.
This time, I took the body to my local Calumet to be cleaned. I will eventually clean the sensor myself, after I do a little more research on the processes available. And again, thanks to all for your input in that regard. I will definitely check out all the processes mentioned.
I saw an antistatic brush in PopPhotography. I didn't think the company was still in business. I had one in the late 70s for dusting vinyl records before playing. It was really amazing. It had a slightly radioactive material in the handle (probably an alpha emitter) that neutralized any static. The dust literally fell off the album even without the brush. It wouldn't do anything for the oil, but the dust was my major issue.
What kind of wet swabs and cleaning fluids do you all use. I assume the cleaner is volatile so it evaporates quickly with no streaking.
Thanks again and I'll let you know how the cleaning went. (I also gave them a print of all the spots! courtesy of lightroom5 and Photoshop.)
Oh! does anyone know how to find the shutter counter on the D7100?
