Referencias

When the popularity of the 180 mm lens made it the preferred long focus lens, many photographers wanted a compact lens that could be handheld with good results. Low weight and some reduction in maximum aperture go hand in hand.

Compared to the 3.4/180 mm design that was introduced several years earlier the image quality is a bit modest and the price difference only 50%. With longer focal length lenses one can magnify the subject, but the chromatic errors are enlarged too and this gives the loss of brilliance that is inevitable with normal designs.

The fingerprint of this lens is remarkable because of the low contrast of the definition of very fine detail. Stopping down does decrease contrast marginally, and image quality stays on the same level. This behavior of many longer focal lenses, namely that performance does not improve that much at smaller apertures, is the result of the residual aberrations and not necessarily, as is often assumed, the signature of optical excellence.
