K&F Concept24mm Full Frame Sensor Cleaning Swab*10 + 20ml Sensor Cleaner, DSLR SLR Digital Camera Sensor Cleaning Swab for Reflex and Mirrorless Digital Camera CCD and CMOS Sensors

A lifesaver of a product. Using a mirrorless camera, the sensors are exposed to much more when swapping lenses. I was apprehensive at first about doing this myself, but I didn't have time to send off my camera to have it professionally cleaned in time for a trip. The product arrived next day from ordering. The instructions were clear and it worked flawlessly in my experience. I see some reviewers mention smearing, but I think this is probably down to what got onto the sensor in the first place and how much of it there is. If you have smears, then I would suggest you let it dry then use a second or third swab until it is clear (there are many supplied in the kit).

Did the job very well! Cleaned my sensors for the first time, easy peasy!

These swabs worked well but did need some sensor cleaning fluid because there were oil spots from the shutter (Nikon D600) and not just dust (also residue from the wet sensor cleaning swabs!). I bought the sensor cleaning fluid from Camarthan Cameras and it didn't leave any residue. Finally I have a clean sensor.I initially made the mistake of buying wet sensor cleaning swabs. These were a huge waste of money as they left a large amount of residue on the sensor and I threw them away.This was the first time I've cleaned my sensor and it took me a while to work out that the camera battery needs to be fully charged before the mirror will lock up.

only thing is the liquid comes out a little quick.. so be careful but a great product

Cleans the sensor well, exact size for my full frame sensor but, need to ensure you read the instructions so not to over soak the swab (as I did first time). Nice bit of maintenance kit to have.

Used for OM-1 Mk II - does a sterling job.

Good for cleaning camera sensor. Would buy it again.

I was getting quite a few spots in my photos and I needed to get my sensor cleaned in a hurry. I normally take it into a service but I thought I'd try these. I used a single swab with a single pass on each end. There was only just enough room in my D810 to get the swab on the sensor and the swab scraped the sides as I pushed it down. It covered the sensor OK though. I used two passes (on on each end of a swab). I just shot an f11 test shot of the sky and yay! No spots
