For Lens Dust: Avoid changing lenses in areas where there is a lot of dust or debris ( on the beach, on a gravel path, in windy conditions) Use a dust blower to clean your lens prior to attaching it to the camera; Always put on your lens cap when the lens is not in use; For Sensor Spots:
10-10-2013· I was surprised because I had never seen dust from a lens affect image quality in this way. It could be that the rear element of the Tamron macro is particularly close to the focal plane. The blobs bothered me so I was glad I solved it but, to be fair, had almost no effect "normal" image quality (which is true in a lot of cases for sensor dust as well).
02-08-2011· I had a spot that I thought was a sensor dust issue. Cleaned the sensor, and nope, still there. It only occurred with this lens, stopped down beyond and when the lens was zoomed to 24 (or close). Plus, zooming could have a slight effect on the position of the spot. That’s when I thought…. this has got to be dust on the rear lens element.
08-10-2009· As an aside to the other answers, the one thing that you can do to confirm a lens vs. sensor question is to see what happens once you swap lens. If it is the sensor, you should get the same dust spots no matter what lens (although their sharpness and size will vary with aperture).
10-10-2013· Quote Reply Topic: Sensor vs. Lens Dust Posted: 17 July 2015 at 03:00: I recently noticed some small spots on macro images taken at a small aperture on my old A330. I semi-regularly clean the sensor using a Rocket Blower, and have also wet-cleaned it a couple times over the years.
Dust is much easier to clean out. I usually take of the lens, hold my camera sensor side facing down, and give it a few strong blasts with my rocket blower. To test if you got them all, I like to shoot a longish exposure (1 second or so) of a white wall at the smallest aperture setting (F/16, f22, F64, etc.) the motion blur of a long exposure makes the dust easier to spot.
22-12-2020· A good camera sensor cleaner can be a vital "just-in-case" tool to keep around your gear. While modern interchangeable lens cameras have integrated sensor-cleaning systems that do a decent job of getting rid of minimal amounts of dust, sooner or later your DSLR or mirrorless camera is going to need its sensor cleaned manually.
03-05-2013· My guess is that the dust is so old that it has been fused onto the sensor over time (by absorption of moisture from the atmosphere turning it into a mini-mud) and that a mere puff of air won't fix it. That does mean getting more physical with fluid and swabs.
06-05-2021· 1. The dust is most likely “on the sensor.”. Technically, the dust is most likely on an optical filters in front of the the sensor...typically a band pass filter that blocks ultra violet and infrared red frequencies. An ND filter is probably the lowest cost work around other than disassembly yourself. Dust in the lens will usually not be ...
12-02-2018· The dust on the rear part of the lens, however, does affect the final image because the light directly hits the sensor and anything blocking the light will also show up on the sensor (especially when it is large). Always keep the rear lens element of your lens clean! If you do not know how to do it, my next article will be on how to clean SLR ...
If you are planning to clean your digital camera — find products tailored to your digital SLR or mirrorless camera be attentive when you start sensor cleaning. You can find on this site two different ways to clean your digital camera sensor — wet (to remove oil, smear, lubricant) and dry (to remove dust, sand).
29-10-2015· This is the typical appearance of sensor dust. Dust on the lens rear element will never be so well defined, won't be aperture dependent, and will be visible throuh the viewfinder, while sensor dust, of course, is only in the picture. Dust on the front element won't be visible as specks at all, it will decrease contrast in a more vaguely defined area.
27-06-2007· Looks like a textbook case of sensor dust to me. Dust on a lens almost never is visible as a discrete spot on the image, although a lot of dust might increase flare. I suppose you could see a bit of lens dust if it was (a) an extreme wideangle used (b) at a very small aperture and (c) focused close.
26-08-2015· New Camera - Smear on Sensor / Dust. Aug 25, 2015. Hi guys, I have recently purchased a FF camera... Barely used it, maybe 500 shots, but most have been with the same lens, changing it maybe 6 or 7 times in 3 weeks. I am anal about dust on the sensor so shot F22 images of sky etc etc to see if I could find any...
27-05-2018· Here's my reasoning: when opening the body to change lenses, the sensor is very close to the opening, and there's no real recessed chamber for dust to get into and float around, looking for places to settle - essentially, there's always air flow over the sensor and when the lens is placed on the body, there's very little room between lens and sensor to trap any dust inside.
14-07-2019· Now when the lens is stopped down and aperture is significantly smaller, say at f/8, light rays coming from the lens diaphragm are perpendicular to the sensor filter. Because the angle is more or less straight, dust specks also cast direct and defined shadows on the sensor. That’s why dust shows up in images much smaller, darker and with more ...
Once inside, they can settle on the mirror or sensor. Once you start changing lenses, the likelihood of dust finding its way to your sensor skyrockets. There are steps you can take to minimize the dust (holding the camera with lens mount facing down while changing, not changing lenses outside, etc.), but sooner or later it’s going to find you.
