I've no experience with either the Tamron or the version II 100-400, but I'd be willing to bet heavily that the Canon is optically superior.

Strange enough but optically tamron is almost perfect and comparable to L series of canon zooms.

There is no replacement for displacement, so you can't beat true 600 mm by cropped 400 - I mean if you shoot fighters at the distance.

Why is that?
the-digital-picture.com wrote:If I make the dangerous (but likely at least close to correct) assumption that the Canon EF 600mm f/4 L IS II USM Lens is a true 600mm lens, I can use its angle of view to compare it to the 150-600's angle of view at 600mm. On a full frame body, the 600 L IS II properly frames a 23.62 x 15.75" (600 x 400mm) target at 33.92' (10.34mm) while the Tamron (at 600mm) frames the same target at a modestly shorter distance of 32.23' (9.83m). The fractional multiplier created from those two distances would indicate that the Tamron's longest focal length is more like a 570mm lens (95% of 600mm).

The Sigma looks a little sharper at the shorter end, but the Tamron wins out at full telephoto; crucially it's as sharp at 600mm as the Sigma is at 500mm. The price you pay for this is higher pincushion distortion, though. The Tamron avoids the Sigma's slightly-troublesome vignetting characteristics at 150mm.
Compared to the venerable Canon EF 100-400mm f/4.5-5.6L IS USM, the Tamron is simply sharper wide open through the entire shared zoom range, and of course usefully longer. Impressively, it's also a match for Nikon's pricey AF-S Nikkor 80-400mm f/4.5-5.6G ED VR in terms of sharpness, although the latter shows lower CA. It's a similar story with the Sony 70-400mm F4-5.6 G SSM II; the Tamron's extended range comes with no significant image quality penalty at all.

Sure!
This one was with a 1.4x II (manual focus) (marginal, I admit):

These were without extender:

Protip: contrail shots are "off airport", so if you search for that term (exactly like I wrote it), it should result in contrail examples.
