....esoteric, perhaps elitist thread but nevertheless interesting especially to someone who has to make a choice. Surely no one with both of these in his/her collection?!

I would love a 300mm f/2.8, but to be honest, i would be slapping on a TC almost all the time, so having a native 600mm lens would be ideal. f/8 is a little slow for what i need (forests at dawn/dusk), but i guess this is where the ISO performance of the 5D III should come in.... hmmmmm.... I am extremely interested in this lens! I guess the 4000 Euro i would save on this lens could go to some awesome trips!
Thanks for sharing the images ... from whatever I read/saw so far, I am very impressed with the Tamron ... the fact that people are actually comparing it with lenses that cost far more, speaks volumes for the Tamron which costs just a little over $1000 ... looks like the third party manufacturers (especially Sigma & Tamron) have really stepped up their game. After the announcement of this Tamron lens, Nikon has recently dropped the price of their newest 80-400 VR II lens by $400.
Here's a close-up of a boar's face. It has been processed, and purposefully slightly oversharpened to emphasize the bristle texture.
Mine arrived yesterday and my initial impression is that It's well worth the money. It handles well and fits nicely on the 70d. Really big lenses dont match well with a smaller body like that but this one seems just right.The IQ is what I expected, really good to 400 and good to 600 same thing for the af. I think the sigma 120-300 with the canon tc's is still better but this lens is 1/2 the weight and less than 1/3rd the price (1/4th if you add the cost of the converters) if you are looking for a packable high quality long zoom with an attractive price then I don't see how you could do much better, I am very pleased so far.
A quick sharpness test....
The goal is to see what effect the F stop has on sharpness with the 150-600 when used at 600mm
All shot with a 60D from a distance of 20 feet and processed in lightroom. All images are with the Tamron 150-600 profile enabled and with chromatic aberration correction enabled.
The target is the fine print on the back of the packaging of a laser pointer... it was the smallest size printing that I could find lying around the house.
The first image has the colour balanced, sharpness slider at 0, noise reduction slider at 0
The second image has the sharpening slider at 80, noise reduction slider at 50, and blacks level at -50. There is a typo on the picture description.... The first bar is F6.3, not F5.6.
Obviously F8 or F11 is far sharper than F6.3 and it falls of by F16. With sharpening enabled, F11 appears slightly better than F8. When you consider that I could not see the pattern around the "danger" symbol when it was inches from my face, yet the lens could pick that up from across the house, this lens is great bang for the buck!....
