5 out of 10 points and not recommendedIt took a pretty good imageTamron needs to rethink the back of this lens
I test drove the New Tamron 15-30mm 2.8 for about 10 days. I was in Las Vegas shooting indoors and outdoors. I used a Nikon 810 as my Camera. IT is a heavy lens...which I did not mind. The Construction Quality upfront is excellent...BUT..Tamron didn't have that same assurance as with the back of the lens. You can see the inside working parts...which in time would seemed to collect dust and moisture..which would play havoc with the electrical system. Tamron Truly needs to rethink that.reviewed April 14th, 2015
I appreciate the VC in the Lens...But Sometimes the AF has a hard time figuring out what to do. Right off the bat when I connected the Tamron to my Nikon D810..It was stuck on 15mm and made a clicking sound...I moved from 15mm to 20mm and it started to Auto focus Correctly...In low light..This lens had a difficult time in searching for what was what.
This Tamron Lens...Did Not WOW me, Like it Wowed Matt Granger. I am not sure why. I didn't mind renting it. But I would not purchase this lens. And Tamron needs to address the non weather sealing in the back of this expensive lens. Quality Issues will arise for the poorly constructed rear of this camera.
Picture Quality? Not so sure. IT did take a good photo, but I was not WOWED. I would recommend that all would test drive it first...before giving your funds to Tamron.

Ever so often someone get's it right. Sigma Did. And it didn't cost $4,000 Grand!reviewed April 14th, 2015 (purchased for $800)
Sigma along with their 35MM Art...Got it right. I was extremely impressed with Picture quality and performance with this Sigma 50mm 1.4 Art. It is a heavy Lens, it is Longer than any other 50mm..Other than the Otus 55.
The Construction Quality as with the 35mm Art is Superb.
Image Quality on my Nikon D810 ..Excellent! If you are using this lens on a Canon...remember you have old dusty Canon Sensors that cannot keep up with Sony's Sensors. lol
Excellent Lens. Very Quite AF. Never heard it. Heavy Long Lens...that felt Great with my D810 and Battery Grip.
I highly Recommend this Sigma 50mm 1.4 Art Lens. It is one of the best Lenses I have ever used.
