It's not so much a defect as a property of wide-angle lenses: they distort things on the sides. This distortion is why they are not recommended for portraiture. Of course, the very same distortion is what gives wide-angle its power, making it great for photographing interiors (making them look larger) or when going for an "artsy" effect.


Two things common to Wide angle lenses can do this, barrel distortion and perspective distortion. For barrel distortion, when pulling in a very wide amount of information from off axis, light gets distorted based on how extreme of an angle it is coming in at because the lens can't completely correct for how far off the lens axis the light is. On the ...


It's all about relative distances. Wide angle lenses don't distort, take a photo from the same distance as you'd use a 50mm lens and crop, and you'll see none of the trade mark wide angle look. When you get close to fill the frame, features that stick out such as noses are relatively much closer to the camera than the rest of the face so they appear much ...


Like all things in life, you need to make a choice: The TV or the girl(s)? Also, consider how something polar, like the earth is displayed as a flat map? How warped is that?


The first and third photos exhibit barrel distortion which is normally to be expected at 18mm when using an 18-55mm zoom lens. Software correction can help, but for best results you need software that includes a custom profile of that particular lens on that particular camera. There are also some perspective issues in shots #1 and 3, which are related to the ...


All the answers are great here --- let me just add than when you apply any correction, you are doing image transformations that put pixels where there were none before --- interpolating and so. So there is some inevitable loss do to the nature itself of the operation, like when you upsize an image. There is a really technical and good article by Roger ...


Yes, wide angle lens distortion is the source here, but not the reason why those heads appear stretched so much. If we had the original photo as the lens imaged it on the sensor of the camera, we would see much less stretched heads and more of perspective and barrel distortion. Correcting for the variety of distortions in post, or in some cases in-camera, ...


Tools like Hugin give you a lot of control over perspective; both of the resultant image and the constituent photographs. There is quite a learning curve to it and IME is worth the effort doing that learning!


To fill the frame with your subject with a wide angle lens, you have to be really close. Perspective — the way lines map from 3D reality to a 2D surface like a photograph — is naturally strongest with objects that are close and flattens as things are far away. That's all there is to it. This is really nicely explained with pictures at What does it really ...


Hopefully this illustration of a pin hole camera will clarify:


According to a review of the E 18-55/3.5-5.6, the observed pincushion distortion at 18mm seems to be what should be expected of that lens. It's quite noticeable but not much different from other manufacturers' equivalent kit lenses, such as Canon's EF-S 18-55/3.5-5.6 IS. More expensive lenses will have less distortion. The distortion is always greatest at ...
