Two images the same size would help, but it's really not possible to tell that much on a monitor. Neither image you posted look that sharp on my monitor. I have an 80~200 f/2.8D ED AF, and it certainly produces sharper images than this, alone and with a 1.4X Sigma APO teleconverter.
Maybe I need to play around with the AF Fine tuning... I did not use a tripod, but had the lens resting on my car window and also used a pretty fast SS to try to eliminate any camera shake...
Thank you all for your comments.
