My question is very simple to answer but I can't answer it for myself. I love the compactness of the "mini beer can" Minolta 35-70 f4. Lens in question here: http://www.keh.com/camera/Minolta-Maxxum-Zoom-Lenses/1/sku-MA070105000310?r=FE It looks like it has manual controls on it even though it is an AF lens. Can the focus and aperture be adjusted manually? Cheers.
