Most of my lenses on the A7 exceed the 4000 LW/PH in the center.Ĭonsider donating, it is about $50 a lens to rent. I will try it on the A7r to see if that center performance is being limited by the sensor resolution, or if it is just the lens.
Remember that the A7 is easy on lenses, so it isn’t good that the corners look so bad given that I focused at the corners for those to eliminate any field curvature (which this lens doesn’t have any). I don’t have a suitable test chart for testing at macro distances so consider this review only from a general purpose lens perspective. I have seen plenty of decent sample shots from the lens at macro distances. (Applies through 1990 only) Model Year 1991 and after January through December. Example: Model Year 1977 September 1976 through August 1977. An earlier serial number version has a strong purple/red coating cast on the lens, while a newer serial numbers appear to have a stronger green/yellow cast. As a macro lens this does fine, note the MTF performance near the center of the frame, the edges will crop themselves away for macro focus distances (guessing). Serial Number Chart Mission Manufacturing. Super Multi Coated Takumar (introduced in 1971) SMC Pentax (Introduced in 1989) In my research I have found that there are at least two different versions of the SMC Pentax 105mm. A lens corrected for close focus (in this case at expense of general use). This is the definition of a true macro lens. The Tokina 90mm “Bokina” does much better as a general purpose lens and is smaller and lighter.
I also have a Lester Dine variant in Nikon mount and tested it on the 3, but never posted the results because it was so bad and I wanted to verify it wasn’t just a bad sample. To be blunt, this lens is not a good general purpose lens and no idea why it sells so high.
