How does eos7d shoot long-distance and close-range scenes and how to adjust the distance?
10- 17mm is super wide angle-mainly shooting scenery, especially big scenes, such as grassland, desert and sea.
17-35mm is a wide angle-scenery and culture, which captures the main focus of this trip and is especially suitable for travel shooting.
35- 135mm is medium focus-humanities and portraits. The 85mm focal length of this focal length is especially considered as the best focal length for portrait shooting, so we can often see that the full-frame machine uses 85mmF 1.8 as the portrait head.
50 mm-this focal length is said to be the most suitable for people to see, so it has become the standard focal length. This is what we often say about the head of a 50 mm lens. However, in an incomplete SLR, it is necessary to multiply the coefficient of 1.6 to get the real focal length (this is the case in 7D), but when it becomes 80mm, it becomes a portrait head. So regardless of the old photographer, this lens is basically configured.
135-200mm- telephoto, suitable for close-ups of figures, lotus flowers, stage, etc.
As for the super telephoto shooting of wild animals, birds and seagulls with a length of 200mm or more, it is even more necessary to make the lens aperture of the focal segment slightly larger, such as F2.8 or F4.5, which are very expensive and are basically used by professionals. I haven't played either, so I won't say it.
If you want to make a good film, you'd better use a fixed-focus lens to select the best photos from the above-mentioned focal segments. It's just that the price is too expensive and there are few users.
There is also a floating aperture zoom lens with a large zoom factor. For example, 18-200mm is known as "a mirror that walks the world". However, its image quality basically belongs to the "general" level. As for the constant aperture zoom lens, the price is similar to that of the fixed focus lens, and it is also very expensive. The picture quality is good. For example, 70-200mmF2.8, of course, the price of 16 thousand is not affordable for everyone.
How to adjust the distance depends on the lens you use. If it is a fixed-focus lens, the focal length cannot be adjusted.
