Considered the lens as I was fed up by poor AF-accuracy of my K100Ds and the lack of a "real" focus ring of modern glasses. Wanted sth. heavy, a reminiscence of the good old days of metal film cameras and metal shells of the lenses that felt and looked like being made of one piece rather than a wagging assemly of plasticy parts. In fact, it feels great. If weight is not the problem, this lense may act as a "handle" to balance the system and prevent your fingers and hands from tiring holding it. The heavy frontelement is kind of a counterweight to the boy itself. However, focussing is not easy either probaly due to the small aperture (4) and sometimes I was given results I never saw befor except from a Tamron 28-75/2.8 that was broken: whitish "aura" around highly lit objects even when they were in focus. I unvestigated this a bit and noted, it was most obvious at 70mm and aperture setting 4.0, while diminishing towards the ends of the focal range and higher aperture nos. It becomes most visible in scenes of high contrast. Else the lense is allright, although using it is more funny than examining the results. The focus ring is pleasingly firm, doesn't turn by accident, small turns achieve small difference in focus, hence control over focus can be quite accurate, provided you can see clearly enough to detect real sharpness. Overall, I give it a 6. There are better lenses around. |
