Wondering about changing DSLR camera lenses in the field? Are people who are doing that using something like a changing bag, like what was used for good old film developing? Well, no actually. They have a different trick up their sleeve: do the DSLR lens changes blindly under a jacket, putting their arms through the sleeve holes. Ah, tricky. Now it would be an even more tricky idea if you used that same trick for successfully developing film in the field.

This page has some useful tips for keeping dust off the sensor when changing lenses, nothing out of the ordinary. Noteworthy is that it has an “emergency tip”: if you can’t get dust off the sensor, try shooting a wider apertures. Also, it recommends regular cleaning of the sensor. However, nowadays thanks to in-camera sensor cleaning mechanisms, this is not as necessary as it previously was, where you might clean the sensor by blowing it off at the end of every photo shooting day.

Particularly, it also has a link to an old but interesting sensor cleaning article. Hence I had to consult the Internet Archive Wayback Machine to get at it. Noteworthy in this article is an explanation of how dust can get “welded on,” which is typically due to humidity changes apparently. Only when dust is “welded on” will you need to do a wet clean, otherwise a dry clean will do the trick. Also, in-camera sensor cleaning mechanisms are basically almost as effective as any dry clean. Keeping your camera in a sealed bag with minimal air when going between different humidity and moisture environments really helps.
Also noteworthy in this article is the mention that you may need to use different wet cleaning solutions based off of what your sensor’s filter coatings are.

Now, that being said, I better find out chemicals are required for wet cleaning of the Pentax K-1 sensor. “Sensor Gel Stick” is one thing that is recommended and apparently works well. Apparently “Eclipse2” doesn’t give good results.
Oh, and especially good tip here on Pentax Forums. Yes, even the new D FA zoom lenses specifically design for DSLR cameras stil have the problem with sucking in air and blowing dust out onto the sensor. So, remember that buying new zoom lenses may not give you a considerable advantage in minimizing dust over your old, existing, non-weather-sealed zoom lenses.

Very interesting here, minor corrections made to the review on the Pentax K-1 Mark II from this site.

More sensor cleaning notes.
Again, I reiterate, because this is important!
Looking to create a dust-free environment? For cleaning DSLR sensors, the same trick for drying film applies here too: Run a shower in a bathroom for a short while, then turn it off. For film negatives, let your film negatives dry in the bathroom. For DSLR sensor cleaning, wait a while to get the humidity to return down to normal to avoid condensation on the sensor, then clean your sensor in the bathroom.

Also note, this is the official sensor cleaning kit for Pentax cameras: Cleaning kit for sensor O-ICK1.

This is a great video that demonstrates proper wet cleaning of the Pentax K-1 sensor should you wish to do so. But, very important recommendation for both dry and wet cleaning: wear a surgical mask or other mouth cover. If you get nervous, you can breathe faster, releasing microscopic saliva particles into the air. These can get on your sensor and end up making it dirtier.
As for the indicated cleaning solutions, we know those must work, as otherwise why would the poster be using them?

As far as my case of an unclean sensor goes, I’ve checked it over and verified that all dust spots seen are larger, gray ones that people term as “dust bunnies” that can simply be blown off the surface with some air. Normally in-camera sensor cleaning would take care of this, but for whatever reason it’s not getting it off, hopefully this would help, otherwise I could try the static brush or wet cleaning.
Okay, after all this searching, I might just as well buy my own cleaning supplies. Initially, I thought for sure I would only use professional sensor cleaning services, not do it myself, but if the services are not locally available for my camera… I might as well do-it-myself rather than shipping it out. I can create a “toy DSLR” camera to practice on.

Okay, closer look and evaluation of my condition. Probably the sensor spots I’m seeing can’t be cleaned by just a better blow, but most of them will clean away with the anti-static brush.
