Alternatively, it might be the camera sensor is dirty. It seems as though it might be a smush on your lens? The reason you only see it sometimes may be due to focal length excluding it from the image, or focussing straight past it. To provide access to Facebook albums for all viewers, including those without a Facebook account follow the instructions given here The original question pointed to images oin a Facebook page. This provides a proof of concept if not proof of reality of the above as the reason for your problem. In a quick test I was able to image a scrap of paper on the lens front element (with lens pointing vertically upwards) at some camera settings and not at others. As they approach the optical centre their image will be increasingly spread across the whole image and will become invisible. The camera will only image objects that are a substantial part of the lenses focal length away from the optical centre of the lens. Gross dust can be umped into lenses on occasion but this size would be rare. Fungus comes as clumps or fine filaments. Move lens around and note that you can see surfaces etc withing lens once you know what to look for. View towards a bright light (NOT THE SUN) through lens looking in front with light off axis. Open aperture iris using lever at camera end of lens. This would be near the front of the lens to do this. In the two example images I'd expect that the blur on palm tree on roof photo had been shot at a longer focal length (although focus point also affects this. If this explanation was correct I'd expect it to be worse at smaller apertures (larger f numbers) and at longer zooms. The simplest explanation (which Occam says is the preferred one, even though it may be wrong :-)) is that you have a mark on your lens or filter or an especially severe piece of fungus or similar inside the lens and that how it appears depends on degree of zoom and on aperture. Knowing the lens type and settings would be valuable. Knowing if this is cropped (I'm assuming not) and aperture would help in analysis. Having the original images available and the EXIF would help, but, it does seem to be a "real" object. Secondly, upon checking the images, I found that the white spots indeed do appear at smaller apertures of f8 and above.Īnyway, thank you for the help guys, really appreciate it! So I'm quite sure that the problem does not lie within the rear of the lens. And I attached that lens to my DSLR since the first day I bought them and have never removed them once. So I shall get this cleaned at a photographic shop sometime soon and I'll see what happens.įirstly, I have only one lens at the moment so I can't test it out with another lens. I'm a total beginner at this and I'm scared of damaging my lens if I decide to clean it by myself. Thirdly, I checked the front part of the lens and found something like a small mark around the middle. Upon checking the images, I found that the white spots indeed do appear at smaller apertures of f8 and above. I attached that lens to my DSLR since the first day I bought them and have never removed them once. ![]() I have only one lens at the moment so I can't test it out with another lens. ![]() Thanks in advance for the help!Įxtra information provided elsewhere by Apathy: ![]() The first photo was taken 2 days after I bought my DSLR. It's the spot slightly to the left around the middle of the photo. It doesn't appear all the time but only sometimes, but when it does appear, it appears roughly on the same area. ![]() You see, there is this white spot that appears in my photos and I don't know what causes it. So I'm hoping someone can help me out here. I'm fairly new here and fairly new to photography too.
