>>3858767Do you already own vintage lenses?
Then yes, it's worth buying a cheap piece of metal.
Do you have 0 vintage lenses and are looking to buy some, but don't own a vintage camera to use them on?
Then no, it's not worth it - just stick to buying native lenses.
Here's a pic rel. These are lenses I came into possession of, along with a vintage camera body that can be used with them. These are a mix of C/Y mount and M-Mount lenses. The adapters were cheap, and just meant I could use all the lenses I have on MFT.
Temper your expectations, though. Some of these lenses are less than stellar and will exhibit many kinds of aberrations which aren't correctable in-camera. These lenses are also very hard to focus with. Turn on the focus peaking and you'll end up focussing on chromatic aberration, and miss focus in most cases. Also... wide angle lenses cease being wide angle on MFT.
You could get yourself a speed booster, but they're not cheap - they cost about the same as a native lens anyway, and while they give you 2 extra stops of aperture brightness, they only at maximum reduce the crop factor to ×1.71.
