I am heading to Africa in January of 2016 for 2 months and was left short with the 70-300mm L on my trip across South America (including the Amazon) and through North America on my 5DMKIII. So decided to buy something a bit bigger to ensure I don't have the same problem again.
I know there are better size comparisons on the web like Brians at the digital picture. But I did a quick one when the lens arrived as I own most of the main tele lenses except the 100-400mm
Just a quick lens size comparison between the Tamron 150-600mm F5-6.3 VC and all the other telephoto lenses I own Canon 70-300mm L F4-5.6 IS vs Canon 70-300mm DO F4.5-5.6 IS vs 70-200mm MKII L F2.8 IS

Excuse the girlfriends hand the 70-300mm DO struggles from zoom creep.
It is a bit bigger than I thought it was but it has surprised me. Its not any heavier in the hand than the 70-200mm and isn't much bigger either when at 150mm. Its also a much better build quality than I expected and has a gasket on the rear which I also didn't know. It also feels very stable with the 5DMKIII almost perfectly weighted, it doesn't feel cumbersome to me at all. The tripod mount is also very good, its long and easy to use as a handle. I went out and shot a few images with it last night and although its not L quality its very impressive for its size and price. I went and shot some ducks at a pond down the road from me and the lens seems to be back focusing a little so I dialled in -8 and it seemed to sort it at 600mm. At 500mm its really impressive and at 400mm even more so, but if your buying this lens 600 is probably what you bought it for and it is good but I wouldn't call it stellar very very acceptable.
Theres one thing that is a little disappointing, I'm used to the 70-300mm L with its close focus capabilities the 150-600mm you do need to be quite a distance from the subject. On the positive side, unless the wildlife is used to humans the likelihood of getting that close is quite small so it ensures you don't scare it. The backward zoom takes a bit of getting used to also.
I need to run it through Focal to make sure its ok before ensuring its the copy I want to keep. But first impressions are very good! Im very taken with it and I don't usually buy third party lenses. but at nearly 1/3rd the price of the 100-400mm its worth a punt.
I intend on going out and testing it after I have AFMA'd it tonight so I will post some few pics and a few more thoughts once I've done that.
