“The Tamron 70-180mm is an easy recommendation for nearly any photographer.”
Lightweight, compact design
1:2 macro mode
Fast, quiet autofocus
Solid construct high quality
Soft edges at 70mm and f/2.8
Low transmission at 180mm and f/2.8
The Tamron 70-180mm f/2.8 Di III is a brand new tackle a pro-level, constant-aperture telephoto zoom. The focal size is a bit shorter than the everyday 70-200mm, however Tamron’s objective was to make a well-balanced lens for full-frame mirrorless cameras, which targeted the corporate’s consideration on decreased dimension and weight. Currently out there for Sony E mount, the $1,199 Tamron is lower than half the worth and simply over half the load of Sony’s FE 70-200mm f/2.8.
So it should not be any good, proper?
Wrong. I don’t know what witchcraft went into making it, however the 70-180mm is, fairly merely, magnificent. This is certainly not a typical finances lens. Tamron made a few sacrifices — chopping 20mm off the telephoto finish and forgoing optical picture stabilization — to make weight, however I’d argue these had been good selections and properly value it. The optical efficiency is top-notch. Attached to a Sony A7R IV, on mortgage from Lensrentals for this evaluation, I used to be very impressed with the element the 70-180mm gave me — not less than, underneath the fitting circumstances.
But can a reasonable third-party lens compete with Sony’s greatest? The reply is, as all the time, it relies upon — however I don’t assume it actually must. More than an alternate, the Tamron 70-180mm f/2.8 is a lifeline to photographers who, because of value, would have by no means thought of the Sony lens within the first place.
Design and dealing with
Daven Mathies | Digital TrendsIf you’ve ever shot a full-frame 70-200mm f/2.8 earlier than, be it for DSLRs or mirrorless cameras, you can be instantly shocked by the appear and feel of the Tamron 70-180mm. It feels prefer it’s in a totally totally different class, weighing simply 1.8 kilos, an nearly unbelievable distinction in comparison with the 3.3-pound Sony 70-200mm.
Unlike most 70-200mm lenses, together with Sony’s, the Tamron doesn’t use an inner zoom mechanism, so the barrel extends as you zoom in. This makes it really feel much less “professional” than its first-party counterpart, but it surely additionally means the lens measures slightly below 6 inches lengthy when retracted — 2 inches shorter than the Sony. And even with the extending zoom barrel, it stays weather-sealed.
The shorter size and lighter weight negate the necessity for a tripod ring, which helps preserve the profile as slim as it’s. The very broad rubberized grip provides your hand a stable buy on the zoom ring, and I truly like that it’s in entrance of the handbook focus ring (reverse of Sony’s lenses) as that placement made for a cushty, balanced maintain. For its half, the main target ring feels very easy and supplies a satisfying handbook focus expertise, despite the fact that it’s not mechanically linked to the focusing parts.
And, sure, you’ll truly need to use that handbook focus ring. The Tamron 70-180mm has a novel 1:2 macro mode, but it surely solely works with handbook focus and at 70mm. The distinction in minimal focus distance between auto and handbook focus is large, and the intense close-ups attainable in macro mode are not like every other f/2.8 telephoto zoom that I’m conscious of.

Other than the lock swap, which holds the barrel at 70mm when the lens is just not in use, the outside is sparse. Where the Sony 70-200mm is plagued by switches to regulate focus and stabilization habits, the Tamron 70-180mm is clean. The lack of stabilization explains a part of this, however I’d have appreciated an auto/handbook focus swap, particularly as handbook focus is one thing you’ll truly need to use on this lens for the aforementioned macro mode. To interact handbook focus, you as an alternative must do it via the digital camera’s menu, which is just a little annoying.
Image high quality
If all of the Tamron 70-180mm f/2.8 did was lower the associated fee and dimension of a well-liked kind of lens, that might have been sufficient. That is, in actual fact, precisely what I’d have anticipated of previous Tamron. But that is new Tamron, and new Tamron is just not content material to be a third-string participant within the lens sport.
Daven Mathies | Digital TrendsThe 70-180mm f/2.8 options six low dispersion parts, three aspherical parts, and 9 rounded aperture blades. This is just not the kind of optical system I anticipate on such an inexpensive lens, though it’s down on the whole variety of parts in comparison with Sony with 19 versus 23 (the Sony additionally makes use of an 11-blade aperture).
Of course, the variety of high-end parts doesn’t all the time equate to excessive efficiency, however on this case, Tamron has delivered. Although there are some caveats I’ll get to, this lens is remarkably sharp. It produced wonderful leads to my take a look at images, revealing particulars in textures I hadn’t seen earlier than. This was, in fact, aided by the 62-megapixel sensor on the Sony A7R IV, and I do imagine this lens comes near revealing that sensor’s potential. More megapixels will reveal lens imperfections, so the truth that the Tamron shines on the A7R IV is a testomony to its high quality.
Daven Mathies | Digital TrendsLarge-open, you possibly can anticipate excellent sharpness within the middle of the body. However, at 70mm, sharpness falls off noticeably towards the perimeters. This is much much less of an issue at 180mm. By f/5.6, the picture is extraordinarily sharp from edge to edge at any focal size. Vignetting is minimal and basically passed by f/4, though general transmission on the telephoto finish at f/2.8 is about 1/3 cease decrease than on the broad finish, because the “vignette” appears to creep throughout the complete body.
To really make the most of this lens’s sharpness constantly, you must use a excessive shutter pace, tripod, or each. Many of my handheld pictures got here out barely smooth because of movement blur, even with the digital camera’s in-body stabilization. This is the place extra lens-based stabilization would have helped. For some photographers, significantly for weddings and even shooters who want to have the ability to work in low gentle and use slower shutter speeds, this may very well be a deal-breaker.
However, the A7R IV reveals faults not like every other full-frame digital camera and is extremely unforgiving. On a lower-resolution physique, such because the A7 III, movement blur received’t be as noticeable, however I’d nonetheless advocate a tripod (and f/4 or smaller) if you need to assure the perfect outcomes.
Color me impressed — astonished, even. I completely love that Tamron determined to start out competing as a premium model. The 70-180mm f/2.8 Di III strikes the proper stability between high quality, dimension, and value. This is a uncommon instance of a lens that I can advocate to only about anybody, from the novice, to the fanatic, to even the skilled.
I used to be just a little upset that so lots of my handheld pictures weren’t completely sharp, however I might probably have solved this by elevating my ISO and shutter pace a cease. As a lot as I want to see lens-based stabilization, I additionally respect how light-weight and inexpensive the 70-180mm is. Again, I feel Tamron made the fitting sacrifices.
Is there a greater different?
No. If you completely want lens-based stabilization or can’t go with out the additional 20mm of attain — and you’ve got $2,599 readily available — then the Sony FE 70-200mm f/2.8 is a good possibility. For the worth, the Tamron 70-180mm f/2.8 actually can’t be crushed.
And, clearly, when you don’t have a Sony E-mount digital camera, you’ll must look elsewhere.
How lengthy will it final?
While it doesn’t really feel as sturdy as 70-200mm lenses with inner zooms, the 70-180mm remains to be properly constructed and may final for a few years.
Should you purchase it?
You already know what I’m going to say. Yes, in fact.
