I am also curious & like to experiment a lot.
Recent i have just compare some of my cameras with a Wide Angle Lens of 0.8X!
They are put in the exact same position.
Camera A Lens 14mm
Camera B Lens 28mm
If I add a WideAngleLen 0.8X on "Camera B at 28mm" should it be 20mm??
But Adding to 0.8X to CamB, I found some side barrels, therefore i adjust lens to about 32mm Originally.
Means 32mm - 0.8X W.Lens. Do i get 32mm-8mm = 24mm??
I have compare with CamA Lens at 14mm & CamB at 24mm*with W.Lens
Results CamB*24mm produce wider results than CamA *14mm...
Why is that so??? I really cant get it unless i am very wrong.
Sorry if i ask silly questions, pls advise. thanks.
