For me, the best alternative

I use the SAL in 2875 for concert photography inside without Blitzer to a Sony alpha 37th
Decisive the 2.8 was able to work at all zoom ranges around without flash.
The images are sharp and rich in contrast. As already mentioned, there are these properties in this price range for me no alternative. Round again I would have liked a little more wide-angle. I recently photographed old newspaper articles in an archive. The close range is just enough yet and the AF was on its borders. Currently however, is enough for me, this lens has a "getting it". Would buy this lens again.
