Anytime you introduce a zoom that meets a difficult challenge on two fronts--a challenging range AND a large constant aperture--you guarantee that it will be bought only by pros and the well-heeled. Moreover, such a lens is nearly always hefty and would require huge filters. Nikon made the right choice in designing its 24-135 zoom a variable aperture. While I don't own the 28-70 f/4 zoom, its size and value make it a "people's zoom" that gets used frequently. ------------------------------ Pentax Clover" <[EMAIL PROTECTED]> wrote: I also wait for a 17-35mm f/:2.8 FA Zoom, and at the same time, how about change hte 28-70mm f/:4 to a 24-80mm f::2.8 ?
