comment:Between winning this lens and receiving it I tried out the new Tamron 28-75 F2.8 RXD at a store on an A7III. I already owned an A-mount version of the older Tamron 28-75 F2.8, but wanted the Sony branded SAM version for AF on the LA-EA3 and Lens Compensation support. The Tamron representative was talking about how the new FE zoom was such a good deal. It had been chosen as lens of the year.

It seems that this lens originally listed for $650, but was raised to $900 in mid 2012. Sony offered $50 off a few times after that, but nothing recently. The box has a sticker from 2010 TIPA awards for "best expert lens". This copy came with the retail packaging and paperwork, front cap and hood, but a generic rear cap. The rubber grips were somewhat white, which I took as a good sign that someone had used it a lot. That gamble paid off. A few minutes of work with a dry toothbrush got rid of the discoloration.

Like the other obvious Tamron A-mount lens designs, the focus ring is backwards from the normal Sony/Minolta direction. I much prefer the feel of plastic and rubber to the exposed metal surfaces currently in fashion. "MADE IN JAPAN"

I was expecting similar optical performance to my copy of the Tamron SP XR, but the Sony SAM lens is actually much sharper on the long end. Like the Sony DT 16-50 F2.8 SSM the image quality is actually better than many of the inexpensive primes.
