Originally posted by jrpower10 TC arrived and works much better than the Tamron. Much less hunting. I'm headed to Yellowstone next week and I'll post some samples when I get back.
Looking forward to seeing them! I sold my Tamron some time ago for good reason - not only did it hunt (and reported an uncorrected FL, IIRC) but the IQ wasn't quite up to par (possibly, again, partly because of the wrong FL for SR).
Here's some encouragement that crewl1 posted this evening, if you haven't seen this yet:
