Introduced in August 2018 it joins Tamron’s stabilized 15-30mm f2.Eight VC lens from 2015 and goes immediately up in opposition to different huge angle zooms, most notably Nikon’s AF-S 18-35mm f3.5-4.5G ED and the Tokina AT-X 17-35mm f4 FX.

Information from the catalog

As normal I’ll take a look on the technical knowledge of the brand new Tamron 17-35mm first. I’ve rated the options with a [+] (or [++]), when it’s higher than common and even cutting-edge, a [0] if it’s normal or simply common, and [-] if there’s an obstacle. For comparability I take advantage of the Tamron 15-30mm f2.Eight VC (“Tamron 15-30mm” for brief), the Nikon 18-35mm f3.5-4.5 (“Nikon”) and Tokina’s 17-35mm f4.0 (“Tokina”).

Dimension (diameter x size): 84 x 90mm (3.Three x 3.5in.) plus 29mm for the lens hood which is 101mm in diameter. Zooming out to 17mm provides 6mm to the full size of the lens. The Tamron 15-30mm is 98 x 143mm. which may be very cumbersome as compared. The Nikon is 83 x 95mm plus 31mm for the lens hood, the Tokina 89 x 94mm plus 33mm for the lens hood. [0]

Weight: 460g (16.2 oz.) plus 31g for the lens hood. The Tamron 15-30mm is 1052g. The Nikon weighs 385g + 19g for the lens hood, the Tokina 591g + 26g for the lens hood. So the brand new Tamron 17-35mm shouldn’t be the lightest of the bunch however because it provides a bigger focal ratio than the Nikon that’s OK. Not less than it’s a lot lighter than its bigger sibling, the Tamron 15-30mm. [+]

Optics: 15 parts (together with Four particular dispersion and a pair of aspherical parts) in 10 teams vs. 18/13 for the Tamron 15-30mm, 12/Eight for the Nikon and 13/12 for the Tokina. The brand new Tamron 17-35mm is the one lens on this group that employs fluorine coating on the entrance of its new lens to repel water, mud, and filth and will make for simpler cleansing. Solely the newly introduced 2nd technology Tamron 15-30mm has a fluorine coating too. [+]

Closest focus distance is 0.28m (11in.) with a magnification of 1:4.9 at 35mm focal size. In my check I used to be capable of get right down to 1:3.9 at 0.25m with handbook focus. The magnification of the brand new Tamron 17-35mm is sort of good however you may have solely 11cm (4.3in.) of working distance at minimal focus distance. A magnification of 1:10 is achieved at 0.47m giving a working distance of 0.30m with lens hood hooked up. The opposite lenses obtain barely smaller magnifications of round 1:4.5 with related working distances and minimal focus distances. [0]

Filter-thread: 77mm which is the de facto normal and shared with the Nikon. The Tokina makes use of 82mm filters. And the Tamron 15-30mm doesn’t supply a filter-thread on its bulbous entrance component. [+]

Picture stabilization: No. The one huge angle zooms that supply optical picture stabilization are the Tamron 15-30mm f2.Eight VC, the Nikon 16-35mm f4.0G ED VR, and the Canon EF 16-35mm 4.Zero L IS USM. [0]

Auto focus: OSD (Optimized Silent Drive), so it additionally works on digicam our bodies which don’t have an AF-drive in-built like Nikon’s D3x00/5×00. Handbook-focus override is by merely turning the main target ring. Similar with the competitors apart from the Tokina the place you want to pull the main target ring again to interact handbook focus. The brand new Tamron 17-35mm lets you alter focus fine-tuning at 5 focal lengths and three distances with the USB TAP-in console. It’s the one lens on this group at present providing this function. However the newly introduced Tamron 15-30mm G2 (second technology) can also be suitable with Tamron’s USB console. [+]

Covers full body/FX or smaller = superb. Similar with the competitors. [+]

Worth: The road value already dropped from the lofty record value of 999 EUR to 730 EUR (incl. 19% VAT) / 599 USD. The Tamron 15-30mm goes for 950 EUR / 1100 USD. The Nikon sells for 700 EUR / 570 USD, the Tokina for 500 EUR / 400 USD. [0]

Comes with no lens-case however the lens hood is included, reversible for transport, and the lens-caps are normal. That’s just like the opposite lenses. Solely the Tamron 15-30mm has a built-in petal hood and solely the Nikon features a smooth lens pouch. [0]

Distance info is relayed to the digicam, so the digicam and flashes can do all of the superior exposure-related stuff with this lens. Similar for the competitors. The Canon model of the lens is at present not suitable with the lens aberration corrections obtainable in latest Canon our bodies to compensate for vignetting, chromatic aberrations and distortion. It is suggested to change these corrections off. Tamron hopes to have a firmware replace at a later date. [+]

Aperture ring: no, similar as with the competitors. The aperture is actuated electromagnetically within the Nikon-version too which makes it the equal of a contemporary E-type Nikon lens and places away with the mechanical coupling that Nikon makes use of on all older lenses just like the Nikon 18-35mm f3.5-4.5G. The Tamron 15-30mm and the Tokina additionally use mechanical coupling of their Nikon mount model. [0]

Sealing: sure, a rubber grommet on the lens-mount plus additional particular weather-sealing all through the development. [+]

The rating within the “features-department” is 0[-]/6[0]/7[+]. So the lens has a well-balanced function set. On the plus aspect is it’s giant 1:2.Eight focal ratio on the brief finish, its fluorine coating, and the compatibility with the TAP-in console.

Options

The marketplace for full-frame wide-angle zooms reaching 35mm focal size is fairly crowded: each producer provides no less than two lenses with the notable exception of Sigma:

  • Nikon has the 18-35mm f3.5-4.5G ED from 2013 for 700 EUR / 570 USD. For extra info see my Nikon 18-35mm f3.5-4.5 evaluate the place it bought a Really useful. Then there’s the stabilized 16-35mm f4.0G ED VR from 2010 for 1150 EUR / 1100 USD which got here Really useful in my Nikon 16-35mm f4.Zero VR evaluate. And at last the 17-35mm f2.8D IF-ED, which is an older design from 2003 however provides a relentless f2.Eight focal ratio and is fairly costly (1700 EUR / 1950 USD).
  • Astonishingly Sigma has no immediately comparable lens on supply. It does have the Sigma Artwork AF 18-35mm f1.Eight DC HSM IF with a vivid fixed aperture of f1.Eight however this lens covers solely APS-C / DX sensors (720 EUR / 800 USD).
  • Canon has the stabilized EF 16-35mm 4.Zero L IS USM from 2014 (980 EUR) and the EF 16-35mm 2.Eight L III USM from 2016 with a road value round 1950 EUR.
  • Tamron provides the stabilized 15-30mm f2.Eight Di VC USD for about 1100 USD / 950 EUR. Its widest angle of view is 110 levels however it lacks 5mm on the lengthy finish of its zoom vary. With its fixed f2.Eight focal ratio and picture stabilization it’s the biggest and heaviest lens on this group however earned a Extremely Really useful in my Tamron 15-30mm f2.Eight VC evaluate. The newly introduced second technology of this lens has improved coating, picture stabilization, and focus drive however optically is similar design. So all outcomes proven right here from the primary technology lens relating to sharpness, decision, coma, and Bokeh  needs to be legitimate for the 2nd technology lens too.
  • Tokina has the AT-X 17-35mm f4.Zero FX from 2011 (500 EUR / 400 USD) and the AT-X Professional 16-28mm 2.Eight FX from 2010 (600 EUR / 580 USD).
  • Sony has two choices overlaying 16-35mm focal vary for full body e-mount our bodies: the FE 16-35mm f4.Zero ZA OSS (1200 EUR) and the FE 16-35mm f2.Eight GM (2400 EUR). Gordon’s tried the latter and put collectively some pattern pictures in his Sony FE 16-35mm evaluate up to now. As the brand new Tamron shouldn’t be obtainable for e-mount the 2 Sony lenses are the one decisions for Sony house owners except they use a Canon EF to Sony E mount converter.

Focus and zoom

Focus accuracy and repeatability is crucial to constantly produce sharp pictures. Repeatability (the accuracy of deal with the identical topic after repeated focus-acquisition in part detect mode) of this lens at normal settings and 35mm focal size is excellent (measured 99.4% in Reikan FoCal) with no outliers over a sequence of 40 pictures. There isn’t any focus variation whether or not the lens focuses from a more in-depth distance or from infinity. At 35mm focal size the lens focuses with out looking in round 0.6 sec from infinity to 0.47m (1:10 magnification), which is quick sufficient in my e book. The Tamron 15-30mm wants solely 0.Three sec whereas the Nikon is the slowest of the bunch at 0.7 sec. Each lenses produce focus accuracy and repeatability similar to the brand new Tamron. The Tokina reveals the largest inconsistencies in focusing measured solely 89.7% in FoCal with one extreme outlier and wishes 0.5 sec.

The main focus ring of the brand new Tamron has no slack/play between its motion and the focus-action and a throw of 55 levels which is barely sufficient for precise handbook focus. It turns the best way Canon customers are used to however doesn’t supply a window with a distance scale. Its rubberized floor is 15mm huge and it provides fairly some resistance so long as it’s coupled to the interior AF motor of the lens. Once you swap the lens to handbook focus the main target ring strikes extraordinarily straightforward. The main focus ring has laborious limits at minimal focus distance and a bit past infinity, and it turns with the AF motion. This disturbed me fairly a bit as a result of after I maintain a lens my fingers usually contact the foremost ring.

The zoom ring turns by 60 levels the best way Nikon customers are used to and has a 19mm huge rubber floor. The zoom ring turns turns fairly clean and will be operated with one finger. The main focus ring is on the entrance and the zoom ring nearer to the digicam however not too shut for it to intrude with the protruding nostril the place some digicam our bodies have their built-in flash. Personally I desire having the zoom ring on the entrance which solely the Tamron 15-30mm provides.

AF-operation is audible from the surface however in the event you file video with the built-in microphone the AF-drive produces no laborious tocks/clicks at the beginning or cease of focus-movements and motion was not too noisy. The Tokina is a bit noisier, the Tamron 15-30mm strikes virtually silently however produces annoying clicks at the beginning and cease of a spotlight motion, and the Nikon is the quietest total.

As you pull focus, you’ll discover some focus respiratory: the picture turns into much less magnified at nearer focusing distances. When I adjusted the main target from infinity to 0.47m on the Tamron at 35mm focal size, I measured a 2% lower in magnification. The Tamron 15-30mm, Nikon and Tokina all present an identical lower. So these lenses mustn’t produce disturbing focus respiratory when recording video. Superb!
