So the charts shown here are just for the Tamron? The second set of charts that start with f/2 on the top left are the ones on the Tamron webpage so they must be just for the Tamron. So not comparison charts correct? My curiosity is getting the better of me. I should be working on my first bird shoot with the Z600 f/6.3 pf ... stopped in the middle of processing for this and dinner
By the Tamron is only slightly lighter (6.9 oz) than the Nikon 70-200 f/2.8 and when I had them both the "feel" in hand felt about the same possibly because the tamron does not change focal lengths internally. I shot both in the same lighting etc. indoors in weird light and the Tamron was as good as the Nikon in the output for the images I took but that was not an apples to apples because the Tamron was at f/2 and at a shorter focal length than the Nikon in many of the images. My use there is primarily from 35 to 100.
As someone noted it is geared to weddings, portraits etc. and that is more like what I use it for and even the easter egg hunt shots outdoors would be different than a golf tournament.
