I finally ended up with the TAMRON AF70-300mm F/4-5.6 Di LD MACRO 1:2 and am happy with it so far. I also grabbed a Sigma DG 70-300mm 1:4-5.6 a couple of days later and now I'm just trying to decide which one to keep
So far, the Tamron doesn't "hunt" as much when inside but that's not really a deal breaker for the Sigma since I don't use 300mm much in the house
The close up ability is really close from one to the other as is the general IQ. If the sky ever clears up around here during a full moon I will be putting them to the dreaded purple fringe test
I had hoped to decide before my LBA kicked in again but in the meantime I found a Sigma "Scalematic" 200mm 1:3.5 prime with close focusing which so far I believe is fairly close to 1:2 but that is for another thread (which I did start) and possibly a future review. There's no review posted for this lens either but the darn thing looked so interesting just sitting there...by itself...in the corner.....in the dark... without a camera
Thanks again
