Re: Sony 55-300 or Tamron 70-300 USD

We've discussed this basic question several times recently. Perhaps the most detailed thread was:

My personal opinions are expressed at some length in the message:

And I posted some examples lower in that thread too. Long and the short of it: in my opinion, based on my research and personal experience, the Tamron SP 70-300mm Di USD has better focusing speed, better built quality, full-frame coverage, and overall about equal optical quality, compared to the Sony DT 55-300mm. The Sony 55-300mm may be overall slightly sharper at 300mm (although I'm not convinced of that); and obviously it goes somewhat wider (going from a 100-300 to a 70-300 gets you a 43% wider wide end; going from 70 to 55 gets you wide end an additional 27% wider).

For my own use, where focus speed is very important, the 70-150mm range does the majority of the work, and the 250-300mm range is for occasional extra reach, the Tamron was (and is) the clear winner. YMMV, and if I were most interested in sharpness at 300mm, I might get the Sony DT 55-300mm--or maybe the Sigma 70-300mm DG OS. (And if money is no object, the Sony 70-300 G is probably best, but on the whole only slightly ahead of the Tamron for a lot more money.)
