[QUOTE="Bob Rules, post: 438108, member: 26079"] I ended up doing this test on my tamron 70 -200. I tested at 70mm, 140mm and 200mm. At 70mm, my adjustment was +5. Is that good or bad? When I moved to 140 and 200, I did not need to make any further adjustments. The focus stayed locked in. I also learned that my Targus tripod was a piece of crap. I never understood what everyone meant by sturdy until my rig kept drifting off the target. Needless to say, I will be in the market for a new tripod. I think I have my eye on the mefoto globetrotter. [/QUOTE]
