    As would the forthcoming m.ZD 300/4.

    The lens is a 300mm lens now and the aperture is still 150/2 = 75mm wide. 300/75 = 4, so it's an f4 at 300mm. All DOF and whatever calculations apply as if it was a native 300mm f4.

    only thing why you can get better DOF with TC is because you can come closer with 150 lens ( min.dist ) thats why 40-150PRO have so good DOF on some picture ( it have min dist. 70cm )
