Usually yes: if you want an interchangeable-lens setup that covers a zoom range similar to the FZ1000, it will generally be more expensive, larger, and heavier.

The main reason is that the FZ1000’s 1-inch sensor allows a built-in lens to deliver a very large equivalent zoom range in a relatively compact package. With an interchangeable-lens camera, larger sensors need larger lenses to achieve the same field of view, so matching that reach is harder and costs more.

An ILC will typically give you a larger sensor than the FZ1000, which means better image quality, lower noise, and better low-light performance. But if your priority is keeping a long all-in-one zoom, a bridge camera is hard to match at the same price.

A common compromise with ILCs is to use a standard zoom or a two-lens kit rather than one lens covering everything. That can get closer in cost, especially used, but it still won’t usually match the bridge camera’s convenience.

So the tradeoff is basically:

• bridge camera: cheaper, smaller, huge zoom range, convenient
• ILC: better image quality and flexibility, but more cost/size if you want similar reach
