Olympus continues to add to its Pro lens quiver with the M.Zuiko Digital 1.4x Teleconverter MC-14, available as a useful accessory to the 40-150mm f/2.8 Pro Zoom lens.  Currently, the Olympus M.Zuiko 40-150mm f/2.8 PRO lens is the only lens that this teleconverter works with, but I’d assume that once we see the soon to be M.Zuiko 300mm f/4 PRO prime lens show up, that number will climb to two.

A teleconverter effectively multiplies the focal length of the lens it is coupled to, while decreasing the lens speed by one whole stop in the case of a 1.4x, or two stops when using a 2x tele converter (Oly, feel free to bust one of these guys out too!).  In this case, it converts the 40-150mm f/2.8 lens into a 56-210mm f/4 optic which translates to an effective field of view in full frame terms of 112-420mm.  Not a bad range, and one that for system users essentially turns the 40-150 (80-300mm e-fov) into two very useful lenses if we’re to look at it in Full Frame equivalency as a workhorse, studio portrait/event tele zoom akin to the various 70-200mm f/2.8 lenses as well as the more sport and light wildlife tele zooms of the world in the 100-400mm f/4.5-5.6 flavor, it begins to make a lot more sense as to why Olympus chose this range, as opposed to what would have been a more traditional 35-100mm (70-200mm) lens in the first place.  Hmmmmm…  Continue reading →
