The Tamron 150-500mm f5-6.7 Di III VC (mannequin A057) is an extended telephoto zoom designed for Sony’s Alpha mirrorless cameras and corrected for full-frame sensors. Introduced in April 2021, it enhances Tamron’s 70-300mm f4.5-6.Three Di III RXD or 70-180mm f2.Eight Di III VXD for many who want extra attain.
Not like its shorter siblings Tamron’s new 150-500mm zoom lens options optical picture stabilization (VC) – a necessary characteristic for lengthy telephoto lenses. It is also absolutely weather-sealed together with fluorine coating on the entrance lens and comes with a detachable tripod-collar with Arca-Swiss fashion tripod interface. The lens is fairly compact at 21cm size (with out lens hood) however – like many different lengthy telephoto designs – extends when zoomed in. Tamron has geared up the lens with “flex zoom lock”, a fairly nifty characteristic which let’s you lock the zoom at any place by merely pushing the zoom ring ahead. And for many who wish to shoot small objects the 150-500mm f5-6.7 Di III VC permits for a most magnification of virtually 1:3.
The lens is priced at 1499 EUR / 1399 USD / 1379 GBP and to this point solely accessible for Sony E-mount. However Tamron has introduced that they’re engaged on Z- and RF-mount variations of their lenses. PS – if you happen to’re interested by Tamron’s different full-frame zoom lenses for E-mount I’ve examined to this point take a look at my in-depth evaluations: Tamron 17-28mm f2.Eight Di III RXD evaluation / Tamron 28-75mm f2.Eight Di III RXD evaluation / Tamron 70-180mm f2.Eight Di III VXD.
Information and options
Let’s examine the brand new Tamron 150-500mm f5-6.7 Di III VC (“Tamron 150-500” for brief) to the Sigma 100-400mm f5-6.Three DG DN OS (“Sigma 100-400”), Sony FE 100-400mm f4.5-5.6 GM OSS (“Sony 100-400”), and Sony FE 200-600mm f5.6-6.Three G OSS (“Sony 200-600”). For good measure I’ve additionally added the Tamron SP AF 150-600mm f5-6.Three Di VC USD G2 (“Tamron 150-600”) to the combo. Though it’s a DSLR design from 2016 it was an excellent and standard lens then and nonetheless can be utilized by way of Sigma’s MC-11 Canon EF to Sony E mount converter – which provides 26mm in size, approx. 120g in weight and 250 EUR in prices. As ordinary I’ve rated the options with a [+] (or [++]), when it’s higher than common and even cutting-edge, a  if it’s normal or simply common, and [-] if there’s a drawback.
Dimension (diameter x size): at 93 x 209mm (3.7 x 8.3in.) plus 55mm for the lens hood (113mm diameter) the Tamron 150-500 is sort of quick for a lens reaching 500mm focal size. The Sigma 100-400 is 86 x 199mm, the Sony 100-400 is 94 x 205mm, the Sony 200-600 is 112 x 318mm (all three with out lens hood), the Tamron 150-600 is 108 x 260mm + 97mm lens hood. All lenses apart from the Sony 200-600 prolong when zoomed to their longest focal size: The Tamron 150-500 extends to 283mm which is simply a bit of longer than the Sony 100-400, the Tamron 150-600 goes to 338mm size (with out lens hood). [+]
Weight: 1725g (3.Eight lb.) plus 95g for the lens hood and one other 155g for the tripod collar. The Sigma 100-400 weighs 1140g, the Sony 100-400 is 1395g, the Sony 200-600 is 2115g (all three with out lens hood or tripod foot), the Tamron 150-600 is 1784g + 108g lens hood + 200g tripod collar. 
Optics: The Tamron 150-500mm f5-6.7 Di III VC is a fairly complicated design with 25 components in 16 teams together with 6 particular dispersion components and a pair of aspherical components. The opposite lenses on this comparability are of a equally complicated development. Each Tamron and each Sony lenses have fluorine coating on the entrance lens to repel water, mud, and grime and make cleansing simpler plus improved anti-reflective coating utilizing nanotechnology. [+]
Focal ratio: The Tamron begins with a f5.Zero focal ratio on the quick finish which is par for the course. It’s f5.6 at 250mm, f6.Three at 400mm, f6.7 at 500mm focal size. That is solely barely slower than the Sony 200-600 or Tamron 150-600 on the lengthy finish. 
Closest focus distance is 0.60m (2.0ft.) with a magnification of 1:3.1 and a working distance of 0.37m (1.2ft.) at 150mm focal size. At 500mm focal size most magnification is 1:3.7 which remains to be fairly good and ends in a for much longer working distance of round 1.5m (4.9ft.). For particulars see desk beneath. The opposite lenses on this comparability obtain their most magnification at their longest focal size: That is 1:4.1 at 1.3m working distance for the Sigma 100-400, 1:2.9 at 0.7m working distance for the Sony 100-400, 1:5.Zero at 2.1m working distance for the Sony 200-600, and 1:3.5 at 1.6m working distance for the Tamron 150-600. The Tamron 150-500mm achieves a magnification of 1:10 at its longest focal size at 4.88m (16ft.) distance. [+]
Use with teleconverters: No, the Tamron 150-500 can’t be used with Sony’s teleconverters. Similar for the Sigma 100-400. Each the Sony 100-400mm and 200-600 can be utilized with Sony’s 1.4x and 2x teleconverters. The Tamron 150-600 can be utilized with Tamron’s personal 1.4x and 2x teleconverters. Whether or not this combo works by way of Sigma’s MC-11 mount-converter on a Sony E-mount physique I can’t say. 
Filter-thread: 82mm. The Sigma 100-400 takes 67mm filters, the Sony 100-400 has a 77mm thread, and each the Sony 200-600 and Tamron 150-600 want big 95mm filters. 
Picture stabilization: All lenses on this comparability have optical picture stabilization inbuilt. This works along with the sensor-based picture stabilization of the Sony Alpha mirrorless cameras – apart from the Tamron 150-600. The Tamron 150-500 affords three modes: Mode 1 is normal stabilization, mode 2 is particularly for panning, mode Three maximizes viewfinder stabilization for simpler framing. [+]
Autofocus: All lenses on this comparability supply autofocus with built-in focus drive. Handbook-focus override is by merely turning the devoted focus ring. The main target ring on the Tamron 150-500 has the same old variable gearing of an authentic mirrorless design which permits for very exact handbook focus when turned slowly however can’t be switched to linear gearing. Which makes clean focus pulling for videographers virtually unattainable. The Tamron 150-600 has the same old direct coupling and linear gearing of a lens designed for DSLRs and the Sony 200-600 additionally affords linear response for MF. [+]
All lenses on this comparability cowl full body sensors or can equally be used on a cropped APS-C digital camera physique. [+]
Value: The Tamron 150-500 comes at a advisable retail worth of 1499 EUR (incl. 19% VAT) / 1399 USD / 1379 GBP. The Sigma 100-400 is 980 EUR / 950 USD / 900 GBP, the Sony 100-400 is 2400 EUR / 2400 USD / 2050 GBP, the Sony 200-600 is 1730 EUR / 2000 USD / 1500 GBP, the Tamron 150-600 at present sells for 1000 EUR / 1200 USD / 850 GBP. 
The Tamron 150-500 comes and not using a pouch however the Arca-Swiss suitable tripod mount (with strap attachment holes) and the reversible lens hood is included. Its lens hood has a rubberized entrance finish to forestall dinks and scratches when the lens is ready down on it. And the tripod collar will be fully faraway from the lens. The Sigma 100-400 additionally comes with out pouch and the tripod mount is an optionally available additional. Each Sonys and the Tamron 150-600 include a pouch and have the removable tripod mount included however the Sonys don’t have an Arca-Swiss interface. The lens hood of the Sony 100-400 has a sliding window via which a polarizing or variable ND filter will be adjusted and it additionally has a lock to forestall it from by chance falling off. 
Aperture ring and different management components: Not one of the lenses on this comparability have an aperture ring. However all have a spotlight limiter: The Tamron 150-500 providing three positions: full/inf-3m/inf-15m. You can even choose totally different modes for the optical picture stabilization on all 5 lenses. Each Tamron lenses supply the great Flex Zoom Lock characteristic along with a regular zoom lock at 150mm: merely push the zoom ring ahead to lock the zoom at any place (see beneath). [+]
Sealing: All lenses have a rubber grommet on the lens-mount. Plus additional particular weather-sealing all through the development apart from the Sigma 100-400. The Tamron 150-600mm additionally has a rubberized front-end that acts as a seal when the entrance lens-cap is connected. [+]
At a rating of 0[-]/6/8[+] the Tamron 150-500mm f5-6.7 Di III VC appears to be like like a effectively balanced design with no actual downsides. It’s definitely not a light-weight lens and the worth appears a bit on the excessive facet. Nevertheless it takes you to 500mm focal size at a measurement the place different lenses solely attain 400mm, it has the tripod mount included (which is a necessary accent for any much less longer than 300mm) with Arca-Swiss fashion interface, a versatile zoom lock characteristic and is totally sealed towards the weather. Plus it will possibly attain magnifications of 1:3.1-1:3.7 at very usable working distances.
Two lengthy telephoto zoom lenses
With its 3.3x zoom-range the Tamron 150-500 has a bit extra vary than the 3x of the Sony 200-600 however lower than the 4x zoom-range of each 100-400mm lenses or the Tamron 150-600. On the quick finish the Tamron 150-500mm has an angle of view of 16 levels, in comparison with the 24 levels of the zooms beginning at 100mm and the 12.5 levels of the Sony 200-600mm. On the lengthy finish the Tamron 150-500 affords 25% extra attain/magnification than each 100-400mm zooms however each the Tamron 150-600 and Sony 200-600 attain even 20% additional.
Right here is the angle of view that the Tamron 150-500mm f5-6.7 Di III VC covers in comparison with the angle of view at 100mm, 200mm, 400mm or 600mm:
The distinction between the Tamron 150-500mm f5-6.7 Di III VC beginning at 150mm versus a lens beginning at 100mm is clearly seen and may be a decisive issue for selecting a zoom lens. Not at all times are you able to step again sufficient to get the broader view of 100mm focal size. And the opposite factor of observe: The good thing about reaching 600mm with the Sony 200-600 or Tamron 150-600 is probably not as huge as anticipated. If the picture at 500mm is sharp sufficient, cropping a 42MP shot at 500mm to match the angle-of-view of at 600mm nonetheless nets you round 29MP. This may effectively be sufficient for the supposed goal.
Sharpness and distinction
Let’s take a look on the theoretical efficiency of the brand new Tamron 150-500mm f5-6.7 Di III VC and examine it to another lenses:
These MTF charts present the computed lens-performance of lenses large open with out affect of diffraction at 10 line-pairs/mm (pink) and 30 lp/mm (blue/inexperienced). Increased values are higher (extra distinction) and the nearer the dotted and strong traces are collectively the much less distinction dependents on the orientation of the test-pattern (much less astigmatism). The x-axis shows the gap from the optical axis (=heart of the sensor) in mm.
The Tamron 150-500mm f5-6.7 Di III VC appears to be like excellent in these charts – each on the lengthy finish and the quick finish: Sharpness may be very excessive proper up into the intense corners with solely little astigmatism. This makes the Tamron 150-500 look even higher (on paper) than the Sony FE 100-400mm f4.5-5.6 GM OSS which is well-known for its wonderful efficiency.
In my full evaluation I’ll present you the real-life efficiency at Four mm (“heart”), 13 mm (APS-C-corner), and 20 mm (FF-corner) on a on a 42MP Sony A7R II digital camera.
The Tamron 150-500mm f5-6.7 Di III VC achieves a fairly respectable magnification of 1:3.1 – 1:3.7 (relying on focal size) in close-up taking pictures. The next pictures have been shot at 1:Four magnification the place the realm of sharp focus is simply 144 x 96mm. The crops proven beneath are from 0mm, 13mm, and 18mm off the middle of the sensor respectively. The primary set was shot at 150mm focal size, the second set at 500mm.
The lens is fairly sharp within the heart even large open. However for a bigger space of excellent sharpness you want to cease right down to no less than f11. Sharpness is strongly effected by field-curvature so you might obtain sharper outcomes outdoors the middle by particularly focusing there. See the next instance shot at f11, the place the crops at 13mm and 18mm picture top have been individually centered. That is higher however nonetheless not very satisfying:
Utilizing the lens at 500mm focal size produces significantly better outcomes outdoors the middle with solely little field-curvature. The next pictures have been additionally shot at 1:Four magnification with crops from 0mm, 13mm, and 18mm off the middle of the sensor respectively:
