I've been struggling with my 70-200G for a quite while now, and Sony doesn't seem to see there is anything wrong with it. But now that it's back at Sony again and I still have my A700 ( first time they tried to adjust it with the camera but they failed to do so), I'm able to check if 'el cheapo 55-200 Tamron can do the job in stead.
The point was one of constant backfocus. Particularly the range between 70 and 120 mm was notorious. With one flower behind the other it was pretty sure the AF would pick the one in the back (at F2.8-5.6).
So I did some semi real life testing with objects the 70-200G simply would not handle. But this time with my el cheapo Tamron:
iso 800, 70 mm F/4.5, 1/125 sec (cropped).
For sure the 70-200 G would have picked the flower in the back, and not the middle one (the one on the right is on level with the middle one).
The bokeh of this little lens is pleasing as well, even at 200 mm (iso 800, F/5.6, 1/60 sec (cropped):
I must say that I'm amazed how well this little lens works. It focusses fast, and stopping down a bit (pictures above were all taken wide open) it is sharp. It does remember me of my Samsung (Pentax copy) 50-200 I once had. That one also kept surprizing me, although others were less lucky then I was.
If you need a cheap nice little walk around lens in reasonable light ? Get the Tammy 55-200 !
