The Tamron 150-600 G1's vignetting performance is typically mild for lenses in its class, showing roughly Sigi has three modes instead of two like Nikon and Tamron. All three lenses have a long distance setting for what I would consider default wildlife mode. For Tami this is 15m to infinity, for Sigi 10m to infinity and for Niki 6m to infinity. All three have a “full” setting for when you get closer to your subject. Sigi adds a ”close only” setting (2.8m to 10m) – I could see this as being useful to expedite AF at close distances, however I found it is easy to bump this switch to “close only” mode and then think the AF has frozen. This cost me shots the first day but later I got accustomed to not bumping the switch. Toss up between the three. 12.3) Tripod Foot/Collar I give Tami the slight edge over Niki in AF performance on static subjects just because Tami is a bit faster. Sigi comes in third due to her hunting issues. The Tamron’s F-mount is constructed of metal and in my experience provided the same level of camera/lens coupling as the Nikkor glass I own. As would be the case with any lens weighing over 4 pounds it would be prudent to never let this lens hang from your camera body unsupported. NIKON 1 V2 + 1 NIKKOR VR PD-Zoom 10-100mm f/4.5-5.6 @ 24.6mm, ISO 1600, 10/150, f/5.0 Controls Go for Sigi if you mainly shoot wildlife and want the familiar zoom and focus directions. Consider Tami (use it push-pull if you don’t like the zoom direction) if you want an all-around wildlife plus landscape lens.

Sure, if you want perfect results limited only by diffraction at 600mm, then buy a real 600mm lens, but for the people who buy this lens, it works very well at all settings, especially 600mm. In general, most wildlife shots feature the animal somewhere around the center of the frame, not in the corners. Hence for wildlife I would tend to favor a lens with superior sharpness in the center of the frame over one with less sharpness in the center but better corner-to-corner sharpness. NIKON D810 + Nikkor 200-500mm f/5.6 @ 380mm, ISO 500, 1/1600, f/6.3 Like Niki, corner to corner looks better at shorter focal lengths, especially when stopped down, but even the four shot pano of clouds over the Organs earlier shows softness in the corners. A few short years ago, there were no super telephoto zooms featuring a 150-600mm focal length range. How things have changed... Be sure that your lens is focussing perfectly with your camera. It's always likely that a third-party lens like this will have some focus offset which may need to be adjusted with your camera's AF Fine Tuning.The new Tamron G2 repeats its good performance from the test-charts also in the long-distance shots. Up to 400mm focal length its performance is very good in the APS-C/DX image circle and good FF/FX-corners. At 500mm the lens starts getting softer: just a little at 500mm but clearly visible at 600mm. Stopping down to f8 brings only little improvement but heightens the risk of blur from a longer shutter speed. Use f11 or smaller apertures only when you need the larger depth of field because diffraction clearly takes its toll. VC MODE 3 prioritizes the stabilization of the captured images and forgoes the stabilization of the viewfinder image.

At 600mm the lead of both Tamrons in the APS-C/DX image circle continues with still very good center performance but clearly softening APS-C/DX-corners. And the Sigma Sports again produces the best FF/FX-corner. But for most applications requiring 600mm, I’d say the better center sharpness of the Tamrons is more valuable than the better FF/FX-corner sharpness of the Sigma Sports. More field testing showed that the corner sharpness starts falling off noticeably from about 60 feet from the subject to infinity. Tami and Sigi both beat Niki at long distances with Tami the best at infinity and Sigi better at 60 feet. NIKON D810 + Tamron 150-600mm f/5-6.3 @ 500mm, ISO 125, 1/500, f/8.0 A funny way to think of it is to think of cars. If you need 400mm, then just like carrying 4 people, you want the Mercedes S-Klasse just as you want the Nikon or Canon lens. If you really need 600mm, just as if you need to carry 6 people, then a Dodge Caravan, like this Tamron, does it better for a fraction of the price. The Tamron 150-600mm f/5-6.3 has minor to moderate pincushion distortion at all settings. It won't be visible unless you look for it.On the flip side, when shooting landscapes, corner-to-corner sharpness is more important. NIKON D810 + Sigma 150-600mm f/5-6.3 DG @ 150mm, ISO 250, 1/500, f/8.0 For subjects not requiring good corner sharpness, e.g. wildlife portraits, Sigi does fine. For long distance landscapes Sigi doesn’t do well. As with Niki, if this lens is mated to a crop sensor body, then much of the corner softness woes will go away. 4.3) Tamron

Filter-thread: 95mm. That’s larger than most of us have filters for and may mean that you need to get new filters for the lens. But that’s par for the course as both the Sigma Contemporary and the Tamron A011 need 95mm filters. The Sigma Sports needs 105mm filters which are even more expensive. [0] If weather sealing and focus consistency are a priority, the Sigma 150-600 Sports and Tamron 150-600 G2 should be your top considerations, with the deciding factor likely being the price-to-image-quality performance ratio desired.Nasim’s Imatest results suggest that Tami is better at the long end and Sigi better at the wide end, but I couldn’t discern this difference in the field other than Tami having better corner sharpness – center sharpness seemed equal. I got nice detailed results with Sigi at 600mm. This is cropped to 1:1 Chromatic aberration is distinctly high at 600mm, with strong red-cyan fringing at the edges and corners of the frame. It's not so bad at shorter focal lengths, and is very low indeed at 300mm. Note that while most Nikon SLRs will compensate for this in their JPEG processing, Canon and Sony cameras won't. While I entertain thought of the Sigma 150-600 it too is beastly and the Nikon 100-400 is... well re-read the first sentence. I'd love to have one and when I win the lottery I'll scour the earth to get one. Unless you're deliberately running a test, this lens has less focus breathing than almost any other lens. At 200mm the Nikon 200-500/5.6E VR comes into play and takes the crown regarding sharpness in the center followed by the Sigma Sports and both Tamrons with the Sigma Contemporary being the softest. APS-C/DX-corner performance is pretty comparable between the lenses with the Tamron G2 edging out a small lead. In The FF/FX-corners the Nikon leads again with an excellent corner performance while the other lenses all are visibly softer.

Cameras – LCD screen is heavily worn either by de-lamination or has scratches to it. Rubber grips are starting to come away from the body. VC MODE 1 is the standard mode that strikes a great balance between the stability of the viewfinder image and the stabilization effects. Cons – soft at long distances, especially in the corners at longer focal lengths; big and bulky; large VR shift; initial AF acquisition is slower than Tami or Sigi; less range and shorter reach than Sigi or Tami. 15) Which lens for which shooter? While the Tamron may not be at its best at 600mm, none of the other lenses we're looking at reach that long at all. So to make a fair comparison, we have to look at how they match up across their shared focal length range. For example, in these tests the Sigma 150-500mm F5-6.3 DG OS HSM is no sharper at 500mm than the Tamron is at 600mm. Meanwhile Canon's ageing EF 100-400mm f/4.5-5.6L IS USM simply can't keep pace with the Tamron's far more modern optics; it's simply not as sharp when compared like-for-like on the EOS 7D. The Tamron SP 150-600mm f/5-6.3 Di VC USD G2 is a super-telephoto zoom lens available for Canon, Nikon and Sony A-mount bodies. Announced in September 2016, it’s the second generation model from Tamron and identified by the A022 code compared to the A011 for the original version; the new model is also known as the G2 version.

Just like Nikon's original 80-400mm VR, there are metal nubs left protruding when you remove the tripod collar.
