EDIT: not sure how to delete my post but I just realized the numbers represent the minimum f number, so this makes sense!
I recently purchased both a Canon M50 and Sigma 18-300m f3.6-6.3
I understood that this lens has a narrow aperture range (f3.6 to f6.3).
However on the camera (for example in manual mode and in Av aperture priority mode I can select the entire range of aperture from f3.5 to f22.
Does anyone know exactly what is happening here? I tried searching for an answer but could not find a similar thread. Thank you!
