Digital cameras usually have a higher aspect ratio than cameras using 35mm film. Digital cameras with fisheye lenses can capture wide enough material for many cinematographers, with cropping being negligible. In fact, due to the high aspect ratio, using a anamorphic lens can decrease horizontal resolution. Photographers should try different lenses to determine which ones best suit their needs.
Distorted widescreen is not necessarily 2.40, the traditional aspect ratio of anamorphic lenses is 2.39:1, usually rounded to 2.40. This aspect ratio was originally chosen to perfectly fit 35mm film. However, with the rise of digital filmmaking, this traditional aspect ratio has become less important. Today's digital distortion images can have various different ratios. Using aspect ratios can make distorted images more exciting.
Although a anamorphic lens does not cover the material with black bars, black bars may still appear when the material is projected onto screens with narrower aspect ratios. These bars simply fill the unused parts of the screen. The total lens capture is not affected in any way. The unique shape elements of anamorphic lenses produce horizontal flares when capturing light sources such as the sun or headlights. When used properly, these flares can create visual interest on the screen. Anamorphic lenses are not suitable for everyday filmmaking. However, they can provide a unique look to a film project, thus increasing its value and aesthetic appeal.
While these are the primary advantages of using anamorphic lenses, other factors to consider may affect your choice. Here are some noteworthy points: Anamorphic lenses produce blue horizontal or vertical lens flares. Anamorphic lenses are larger and heavier, making them cumbersome for active shooting. Distortion lenses typically have slower maximum apertures, so you can only use them in well-lit environments. Distortion lenses are more complex and expensive. The image quality of anamorphic lenses is typically not as clear as that of fisheye lenses because they have more glass elements. There are fewer choices among anamorphic lenses. In most cases, you will use horizontally compressed material. This makes composition and framing difficult. Some advanced cameras have a decompression function to address this issue. Distortion lenses often distort vertical lines.
