|comment:||The first copy I won the eBay seller didn't properly package it. The hood cracked and the lens may have suffered internal damage during shipment. There was no other visible damage on the lens and everything seems to work, but it was quite soft at all focal lengths. The second copy is somewhat sharper. This one didn't come with a hood, so I purchased one separately and found it also cracked. "JAPAN"|
It is a rather small lens even when fully extended and quite light. The zoom action doesn't have the smoothness of the older Beercans, but it feels comparable to the DT zooms.
Neither copy exhibits the zoom creep that afflicted my first non-D APO version. Operation is similar to the DT zooms. Lens extends but does not rotate while zooming. The front element extends and rotates while focusing. AF works well with the 1.4X Kenko DGX teleconverter and even works with the 2X DGX teleconverter at the short end of the zoom range. The apertures and focal lengths are properly corrected with both teleconverters.
The 100 mm minimum focal length is limiting especially on APS-C cameras. It performs similarly to the 100-200 F4.5--except the focal plane is a bit flatter at 100 mm than the 100-200 F4.5.
It would nice to find a sharp, properly working copy of this lens and the matching 24-105. The build quality of these late clutched, distance encoder equipped zooms definitely seem to be lower than the original Minolta AF lenses or even the just prior non-D versions.
