Hi,

Could someone please help confirming my calculation ?

Is the following correct ?

>>> On a GH-4 M43 camera, the obtained angle of view on the sensor will be smaller with this Laowa 15mm ( https://www.venuslens.net/product/laowa-15mm-f/ ) than on this Lumix 14-45mm ( https://www.bhphotovideo.com/c/product/657970-REG/Panasonic_H_FS014045_Lumix_G_Vario_14.html ) ?

That is surprising to me as the Laowa is a wide angle lens, and the Lumix isn't, but if I understand correctly, because of the sensor crop factor, I would actually get a 30mm with the Laowa lens, and a 28mm with the Lumix, is that really how this works ?

Thank you !

When you compare lenses on the same camera, crop factor is irrelevant. Crop factor only becomes relevant across sensor sizes.
