Explain plz the Crop x2 thing and if Lenses take it into account?


Im new to photography and confused with the x2 crop and lens

I want to know where is the crop comes from?

BUT my main question is, Do MFT Lenses take the x2 crop into account?

Meaning if I buy a an Olympus MFT 75-300mm lens is that with crop included or not?

When connected to G9 will it be like 150-600 Full Frame Equivalent or

It will be like 75-300MM Full Frame Equivalent because the crop is already counted in the lens.

Please help, i almost made a mistake and got a lens adapter with 0.71 focal reducer and the 900$ Sigma 150-600mm 5-6.3 Contemporary DG OS HSM Lens.

Thank god i stumbled into random, confusingly named video that actually tested that specific lens on Panasonic G9 and lens converter/focal reducer and said that because of the focal reducer you dont gain much, the 600mm lens becomes 768mm on the MFT with 0.71 focal reducer.

If i want something serious i need to check lens adapters without any glass, to get that 600mm into 1200mm on G9 then it may be worth it.

Thanks in adavnce
