Is the canon rf 75 300mm f 4 5 6 good for travel?

Not as a one-lens travel kit. The Canon RF 75-300mm f/4-5.6 is a cheap, light telephoto, and it has no stabilisation. Travel asks for one zoom that covers wide to short telephoto, because you won't want to change lenses in a crowded square. At 75mm the shortest end is too tight for landscapes, street scenes, or the inside of a dim church, and the lack of stabilisation hurts indoors.

Where it earns its place is as a second lens for distant subjects, like wildlife, sport, or a view from across a square. Pair it with a wider standard zoom, and keep the what matters checklist in mind when you choose that first lens. Weigh the whole setup, not just the body, so it still fits in your bag on day five.
