Mamiya Sekor 210mm f/4 ULD

    This is another well built lens from Mamiya. It is my telephoto lens and it fills an important role in my kit. However it is a little slow, it is f/4. I don’t own any other lenses this slow, however f/2.8 medium format telephoto lenses are quite large. I enjoy this lens and it is very useful. And with faster speed B&W films like the Ilford 3200. Very useful lens and definitely worth considering with the Mamiya 645 AFD.

    This lens is great for portraits as well as for when you need a little extra pull. When taking portraits outside it is nice if you want a little bit of distance between you and your subject. Its equivalent to a 120mm lens in 35mm terms. One of the best focal lengths for portraiture is the 135mm focal length and this lens is basically that. It yields very nice results with good image sharpness and bokeh.
