Compared to a DSLR
There are two major differences between an entry-level DSLR and a bridge camera. The first is the size of the image sensor and the second is the fact that DSLRs have interchangeable lenses, while bridge cameras have a fixed optic.
The smaller compact camera sensors used in bridge cameras are the reason that such huge telephoto focal lengths are possible. With the X-S1 having a range of 24-624mm, it is unlikely that any other lens will ever be needed.
Remember, though, that the smaller sensor won’t be able to match the image quality produced by a DSLR, particularly as the ISO sensitivity increases. With such a large focal-length lens, the sensitivity will often need to be increased to be able to use this lens at its maximum zoom setting, even accounting for the camera’s built-in stabilisation.
An entry-level DSLR, here represented by the Nikon D3100, has better image quality, and in this case the camera is slightly smaller. It is also cheaper at around £400, although once a 70-300mm f/4.5-5.6 lens has been factored in for around another £400 it still won’t match the focal length of the X-S1.
Both cameras have a full complement of exposure modes and settings, with an appropriate number of buttons and controls to match.
The decision as to which to buy largely comes down to image quality. The DSLR will always be the better option as far as this is concerned. However, if the camera is to be a one-off purchase and you have no desire to build a system, a bridge camera such as the X-S1 is a good choice. If you already own a DSLR, then a bridge camera may be suitable to get you started in taking wildlife imagery. However, expect a drop in image quality.
