retrocam said:Jay, I thought the RF baselength only impacts the focus on lenses with longer focal lengths. I guess I have to read up (or you can tell me 😀 ) why/how the RF baselength has an impact on lenses with larger aperture.
The RF baselength determines how accurate the RF is going to be. Long focus lenses and those with wide apertures (due to shallow DOF at biggest apertures) require critical focusing.
