I have a Panasonic Lumix DMC-G7 with a Micro Four Thirds mount and an Olympus Zuiko Digital 40-150mm lens in the older Four Thirds mount. I’m confused by adapter listings online, especially ones labeled FD or OM. What type of adapter is actually required, and will any adapter of that type work?

You probably want the Olympus MMF-3 Four Thirds to Micro Four-Thirds adapter. This will give you full electronic communication with the four-thirds lens so you can meter and autofocus the lens, although AF performance can vary, depending on the lens and the adapter. There are several other options, (including the MMF-2, and MMF-1/Panasonic DMW-MA1, and Viltrox JY-43F).
The MMF-1/DMW-MA1 is the earliest version and is a bit bigger and heavier than the later versions. The MMF-2 was redesigned to be smaller/lighter/cheaper, and the MMF-3 added weatherproofing (and is the current version). Functionally, all three are equivalent as they're just doing passive passthrough of the electronic signals.
BTW, you do not have an FD lens, you have an FT (four-thirds) lens; FD/FL is an older manual-focus Canon SLR mount.

Generated from our catalog & community — verify before relying on it.
You need a Four Thirds to Micro Four Thirds adapter — not an FD adapter. Canon FD is a different, older manual-focus mount, and Olympus OM is also different from Four Thirds.
For your Olympus 40-150mm Four Thirds lens on a Lumix G7, the commonly recommended adapters are the Olympus MMF-1/MMF-2/MMF-3 or the Panasonic DMW-MA1. These are essentially electronic pass-through adapters, so they maintain metering and autofocus compatibility with Four Thirds lenses, though autofocus speed can vary by lens/body combination.
Differences are mostly physical: the MMF-3 adds weather sealing; the older MMF-1/DMW-MA1 is a bit larger/heavier; the MMF-2 is smaller/lighter. Functionally they are equivalent for basic use.
So the key is: buy a Four Thirds (4/3) to Micro Four Thirds (MFT/M43) adapter from a reputable brand. Do not buy an FD-to-MFT or OM-to-MFT adapter for this lens.
