Sony FE 70-300mm f/4.5-5.6 G OSS vs Tamron SP 150-600mm

It extends when zoomed, and includes a lock switch so you can prevent the barrel from creeping out inadvertently when the lens is hanging downward. A reversible lens hood is included.

It's not a lot, but since the zoom ring is stiff turning the zoom ring would slightly rotate the entire lens a tiny bit. The focus distance window also seems to be completely inaccurate - I was photographing a deer about 30-40ft away, but the window was stating it was 100ft away. The soft bag it comes with protects the lens somewhat, but is more flexible than the stock Nikon bags, and that makes it more difficult to stuff the lens back in since it keeps collapsing and folding over itself. Lastly, the wide angle lock switch seems somewhat unnecessary, as the zoom ring already functions as a lens lock if you push it forward, while the switch only works at 150mm

At 70mm f/4.5 it scores 3,848 lines per picture height on Imatest's standard center-weighted methodology, an exceptional result. Performance is very even across the frame, with the mid parts and edges bettering 3,700 lines. When looking at photos from a high-resolution body like the 7R II we want to see 2,200 lines at a bare minimum

The lens performed ok, giving me usable shots, but still seems the detail isn't quite there. I took the lens to a local dealer with an Tamron representative and they gave me tips on trying to get the best picture possible ,but even they admit the lens might have to go back. Some how I have acquired lots of dust behind the front element. looking at the side of my lens it appears my lens it cupped which could be a factor in all this

This is a good lens overall. Price is a bit high when compared to versions for other mounts and manufacturers, some of which are definitely superior to this lens. It is light and for the size I found balances well on an a7 series body. Nothing groundbreaking, but its the only option really for a 'travel' size zoom in the Sony lineup

We get some pincushion distortion and noticeably dark corners. Stop the aperture down to f/8 and those corners brighten up throughout the zoom range t...

Autofocus speed is a little above average. Had a hand af lock button. For the cost, it would be nice to have a lower minimum f-stop, but we knew this coming in. The one downside is its a little heavy, which makes taking photos a little less enjoyable

You're kidding. The Tamron SP is better than both of these two. The Canon's only advantage is that it will have the fastest AF but only beating the Tamron by a little. The Tamron has better transmission than both, better CA control, actual 3+ axis stabilization, weather seals the Sigma can't match

One key advantage most mirrorless cameras have over DSLR's is light weight. You lose some of this when you go full-frame. The A6000 (which I also own) and the A6300 are great small cameras systems and I hope Sony will continue to develop more compact and high-quality APS-C lenses.

That's a big savings in weight for photographers wanting a lens that can be used in all types of weather without worry, not to mention price—the Tamron G2 is $600 less than the high-end Sigma Sports 150-600mm. The cost of front filters is less, as well, as the Tamron uses 95mm front filters while the Sigma Sports requires the larger, more expensive 105mm variety. A reversible lens hood is included.

Little to no chromatic aberration. Sharp in bright light. Constant aperture. Cons: Size

Bring a tripod for when you need to rest your poor arms. This beast is heavy but not terribly. It wasn't so bad for me since I was used to the 80-200mm which weighs in about 3.5lbs but *if* you haven't used a heavy lens before be prepared for some adjustments
