I just got a Vivitar Series 1, 28mm-90mm 2.8-3.5 FD mount macro lens. I have never had this kind of lens before so I am not sure if it is supposed to be doing what it is doing. At 28mm (zoomed all the way out) and F/2.8 with focus on infinity, my point of focus is 46 inches from the end of the lens. In other words, at 28mm, I cannot focus on anything further than 46 inches away. I can focus closer - all the way up to about a centimeter from the end of the lens. Of course changing my F-stop to 8, extends the DoF so that I can focus as far at 15-18 feet away but as I want to be able to shoot in lower light situations with a wide angle, stopping down is not an option for me. I want to know if this is what the lens is supposed to do. My experience with non-macro video lenses tells me that at infinity, my focal point should be somewhere around a half mile away, give or take. Is this lens, because it is a macro, designed to do this or is it out of calibration for its infinity point? If it is "broken" is there a way to fix it? I am using the FD adapter and my other prime lenses all function properly, focusing far away at infinity. Thanks for the help.
