A camera with a fixed lens of very long zoom range, built in the shape of an interchangeable-lens body. The reach is its whole argument, and the price of that reach is a small sensor and a dim aperture at the long end.
The name describes a position in the market rather than a technology: between a compact and an interchangeable-lens camera.
What defines it
A fixed lens — not interchangeable — with a zoom range far beyond what a system lens covers, and a body shaped like a system camera with a viewfinder and a grip.
The sixty-times zoom in this catalogue
One product here prints 20-1200 mm with f/2.8-5.9 on a single lens. That is a sixty-times range in one object, and the two aperture figures are the cost of it: the second is nearly three stops below the first.
The trade, stated plainly
You gain a reach no reasonable set of lenses covers, in one object, at one price. You accept a smaller sensor, a dim long end, and no path to a different lens. Nothing in that is hidden — both aperture figures are printed, and the sensor size is stated.
Who it suits
Someone photographing distant subjects in daylight who will not carry a second lens. The figure that decides it is the aperture at the long end, because that is where the reach lives and where the light runs out.
What people ask before they commit
Why is the aperture so dim at full zoom?
Because holding a wide aperture across a 20× or 60× range would need an enormous lens. The published pair tells the story: one bridge camera in this catalogue prints 20-1200 mm with f/2.8-5.9, which is bright at the wide end and nearly three stops darker by the long one.
Would two lenses on a system camera be better?
For image quality at a given focal length, usually yes; for carrying one object that covers everything, no. It is the same trade as a zoom against two primes, taken to its extreme — and the deciding figure is the aperture at the end of the range you actually use.
