The Panasonic Lumix G100 is a Micro Four Thirds body with a 2× crop factor; every Micro Four Thirds lens below fits, and a 25mm frames like a 50mm would on full-frame.

What each focal length gives you on the Panasonic Lumix G100

Because the Panasonic Lumix G100 has a 2× crop factor, every lens's marked focal length acts 2× longer than the number on the barrel. This is the Micro Four Thirds range translated into what you actually get on this body — the 29 native lenses span 16–1200mm equivalent.

Every focal band from ultra-wide to super-telephoto has at least one native Micro Four Thirds lens for this body.

Before you buy: fit checks for the Panasonic Lumix G100

Most lens returns are fit and expectation mismatches, not faulty glass. These are the ones that catch Panasonic Lumix G100 buyers out — all of them follow from the 2× crop factor and the mount, so you can check them before you order.

• Don't buy a 50mm expecting the "normal" look. On the Panasonic Lumix G100 a 50mm frames like 100mm — that's a short telephoto, not a standard lens. The natural 50mm-equivalent view here comes from a 25mm lens, e.g. the Olympus M.Zuiko 25mm f/1.8 (f/1.8).
• Wide-angle gets narrower. A 16mm ultra-wide frames like 32mm on this body. If you want genuinely ultra-wide results, you need roughly a 8mm marked lens.
• The OM System M.Zuiko 12-40mm f/2.8 PRO II is not the low-light answer. At f/2.8 it is 2.3× slower than the Panasonic Leica DG 42.5mm f/1.2 (f/1.2). If you shoot indoors or at night, buy the prime instead — the zoom's convenience won't rescue a dark room.
