Thanks for all the comments and well wishes. I do have two potential buyers waiting for my answers. I have some questions that I don't quite know. In the above test shots, I tried out as much macro as possible as the macro ratio is quite good stated at 1:2.2 but I only tried the macro at 210mm and the closest distance is about 5 to 6 feet.
[Question] Can some of previous owners of Series 1 confirm if the Macro works across the focal range or if macro only works in the longer end at 210mm. I believe it is the later but I am not sure. There is s switch for macro when lens is in 210mm focal range, but once turned on in Macro setting, I recall not able to focus in shorter focal length as in 70mm but it may just be I am too close to the shooting object,
I need help on this question.
Though the heavy weight, I am very impressed on the lens. The test pictures are done in a hurry this morning before work but the color, details and perhaps sharpness come out quite unexpectedly well, they definitely beat my favorite lens with DA 50-200 in both color and bokeh and I think they may get very close in IQ to more expensive lens.
My two favorites in the test are done in Macro at 210mm
