Tamron 70-180mm f/2.eight Di III
“The Tamron 70-180mm is a simple advice for practically any photographer.”
Light-weight, compact design
1:2 macro mode
Quick, quiet autofocus
Strong construct high quality
Delicate edges at 70mm and f/2.eight
Low transmission at 180mm and f/2.eight
The Tamron 70-180mm f/2.eight Di III is a brand new tackle a pro-level, constant-aperture telephoto zoom. The focal size is a bit shorter than the standard 70-200mm, however Tamron’s objective was to make a well-balanced lens for full-frame mirrorless cameras, which centered the corporate’s consideration on diminished measurement and weight. At the moment obtainable for Sony E mount, the $1,199 Tamron is lower than half the value and simply over half the load of Sony’s FE 70-200mm f/2.eight.
So it should not be any good, proper?
Mistaken. I don’t know what witchcraft went into making it, however the 70-180mm is, fairly merely, magnificent. That is in no way a typical price range lens. Tamron made a few sacrifices — slicing 20mm off the telephoto finish and forgoing optical picture stabilization — to make weight, however I’d argue these have been good choices and properly price it. The optical efficiency is top-notch. Hooked up to a Sony A7R IV, on mortgage from Lensrentals for this assessment, I used to be very impressed with the element the 70-180mm gave me — a minimum of, below the fitting situations.
However can a reasonable third-party lens compete with Sony’s finest? The reply is, as at all times, it relies upon — however I don’t suppose it actually must. Greater than another, the Tamron 70-180mm f/2.eight is a lifeline to photographers who, attributable to price, would have by no means thought-about the Sony lens within the first place.
Design and dealing with

Should you’ve ever shot a full-frame 70-200mm f/2.eight earlier than, be it for DSLRs or mirrorless cameras, you’ll be instantly bowled over by the feel and appear of the Tamron 70-180mm. It feels prefer it’s in a totally completely different class, weighing simply 1.eight kilos, an virtually unbelievable distinction in comparison with the three.Three-pound Sony 70-200mm.
In contrast to most 70-200mm lenses, together with Sony’s, the Tamron doesn’t use an inside zoom mechanism, so the barrel extends as you zoom in. This makes it really feel much less “skilled” 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 offers your hand a strong buy on the zoom ring, and I truly like that it’s in entrance of the guide focus ring (reverse of Sony’s lenses) as that placement made for a cushty, balanced maintain. For its half, the main focus ring feels very clean and gives a satisfying guide focus expertise, though it isn’t mechanically linked to the focusing components.
And, sure, you’ll truly need to use that guide focus ring. The Tamron 70-180mm has a singular 1:2 macro mode, but it surely solely works with guide focus and at 70mm. The distinction in minimal focus distance between auto and guide focus is huge, and the intense close-ups doable in macro mode are not like every other f/2.eight telephoto zoom that I’m conscious of.

Apart from the lock change, which holds the barrel at 70mm when the lens is just not in use, the outside is sparse. The place the Sony 70-200mm is affected by switches to manage focus and stabilization conduct, the Tamron 70-180mm is clean. The shortage of stabilization explains a part of this, however I’d have appreciated an auto/guide focus change, particularly as guide focus is one thing you’ll truly need to use on this lens for the aforementioned macro mode. To have interaction guide focus, you as a substitute must do it by means of the digital camera’s menu, which is a little bit annoying.
Picture high quality
If all of the Tamron 70-180mm f/2.eight did was lower the fee and measurement of a well-liked sort of lens, that may have been sufficient. That’s, in actual fact, precisely what I’d have anticipated of outdated Tamron. However that is new Tamron, and new Tamron is just not content material to be a third-string participant within the lens sport.

The 70-180mm f/2.eight options six low dispersion components, three aspherical components, and 9 rounded aperture blades. This isn’t the kind of optical formulation I count on on such an inexpensive lens, though it’s down on the overall variety of components in comparison with Sony with 19 versus 23 (the Sony additionally makes use of an 11-blade aperture).
After all, the variety of high-end components doesn’t at all times equate to excessive efficiency, however on this case, Tamron has delivered. Though there are some caveats I’ll get to, this lens is remarkably sharp. It produced glorious ends in my check 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. Extra megapixels will reveal lens imperfections, so the truth that the Tamron shines on the A7R IV is a testomony to its high quality.

Huge-open, you may count on superb sharpness within the heart of the body. Nevertheless, at 70mm, sharpness falls off noticeably towards the sides. That is far 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 primarily passed by f/four, though total transmission on the telephoto finish at f/2.eight is about 1/Three cease decrease than on the broad finish, because the “vignette” appears to creep throughout your entire body.
To actually reap the benefits of this lens’s sharpness persistently, it’s a must to use a excessive shutter pace, tripod, or each. Lots of my handheld pictures got here out barely gentle attributable to movement blur, even with the digital camera’s in-body stabilization. That is the place extra lens-based stabilization would have helped. For some photographers, notably for weddings and even shooters who want to have the ability to work in low gentle and use slower shutter speeds, this could possibly be a deal-breaker.
Nevertheless, 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 gained’t be as noticeable, however I’d nonetheless advocate a tripod (and f/four or smaller) once you need to assure the very best outcomes.
Coloration me impressed — astonished, even. I completely love that Tamron determined to begin competing as a premium model. The 70-180mm f/2.eight Di III strikes the proper steadiness between high quality, measurement, and value. It is a uncommon instance of a lens that I can advocate to only about anybody, from the newbie, to the fanatic, to even the skilled.
I used to be a little bit disenchanted that so lots of my handheld pictures weren’t completely sharp, however I might seemingly have solved this by elevating my ISO and shutter pace a cease. As a lot as I wish to see lens-based stabilization, I additionally respect how light-weight and inexpensive the 70-180mm is. Once more, I believe Tamron made the fitting sacrifices.
Is there a greater various?
No. Should you completely want lens-based stabilization or can’t go with out the additional 20mm of attain — and you’ve got $2,599 available — then the Sony FE 70-200mm f/2.eight is a superb possibility. For the value, the Tamron 70-180mm f/2.eight actually can’t be overwhelmed.
And, clearly, when you don’t have a Sony E-mount digital camera, you’ll must look elsewhere.
How lengthy will it final?
Whereas it doesn’t really feel as sturdy as 70-200mm lenses with inside zooms, the 70-180mm continues to be properly constructed and will final for a few years.
Must you purchase it?
You already know what I’m going to say. Sure, in fact.
