Small focal length vs large focal length
WebbThe distance between the objective lens and the eye-piece is the sum of their focal lengths, and since the eye-piece is of small focal length, the objective lens should be of greater … WebbFor example, shorter lens focal lengths (i.e. 16mm, 24mm, and 35mm) have a larger angular field of view, hence the term “wide-angle” lens. These lenses also tend to have a …

WebbThe short answer is no; as I already mentioned above, focal length is determined by the distance between a lens’s focal point and the camera’s sensor. And as a camera’s sensor – whether big or small – is always positioned in the same place, this measurement is not altered by the size of the sensor. Webb14 jan. 2024 · Plössls have a wide field of view (around 52°), so they can be used successfully for planetary as well as deep-sky viewing. The drawback is the short eye relief that becomes an issue with focal lengths of 12mm or less. 'Eye relief' refers to how far your eye must be from the eyepiece in order for you to see the entire field of view.
