The major plus of this lens (and the Nikkor) is its 1:1 magnification. I wouldn’t overrate the differences in focal ratio when focusing closer. The Nikon shrinks to f4.8 at 1:1 (f3.3 at 1:2). The focal ratio of the Tamron shrinks from f2.8 to f5.6 at 1:1 magnification (f4.2 at 1:2). The Nikon 105/2.8 reaches 1:1 at 0.31m, its working distance is 15cm (24cm at 1:2). The working distance between the front element and the subject is 14cm at 1:1 magnification (22cm at 1:2). So this is a “real” macro lens, not some of the zooms claiming to be “macro”-designs but only reaching a maximum magnification of 1:3 or thereabouts. Plus fluorine coating at the front lens for easier cleaning. It includes three low dispersion elements and coating with a nano-structured layer. ![]() The lens design and the MTF curves look exactly the same as with its predecessor. This is similar to the Nikon 105/2.8 with 14 elements in 12 groups. ![]() This is lighter than the Nikon 105/2.8 which comes in at 750g. Which is par for the course: The Nikon 105/2.8 is 83 x 116mm resp. I’ll compare it with the AF-S micro Nikkor 105/2.8G ED (the “Nikon 105/2.8” for short). I’ve rated the features with a (or ), when it’s better than average or even state of the art, a if it’s standard or just average, and if there’s a disadvantage. It works for anything you order at any time – thanks for your support!Īs usual I’ll have a look at the technical data first. PS – don’t forget you can support my work next time you order anything at Amazon, B&H or Adorama by first clicking through to them using the links above and in the sidebar. To find out how it performed I tested the Tamron SP 90mm f2.8 Macro VC ii on Nikon’s 36MP D810 and compared the results against Nikon’s own AF-S 105mm f/2.8G ED Micro Nikkor and the predecessor from Tamron model F004. So it’ll be interesting to see whether Tamron managed to implement an effective image stabilizer and excellent optical design to differentiate itself from other stabilized long macro lenses. That’s why many photographers rely on tripods for their macro work. But with macro lenses you have two additional challenges: shake becomes more pronounced the larger the magnification, plus normally you need to stop down further to achieve a decent depth of field. But with a good image stabilization (dubbed “Vibration Control”/VC by Tamron) there’s hope to get sharp shots hand-held at around 1/25 sec at normal magnifications. The old 1/focal-length rule for shutter-speeds that are on the safe side no longer applies for the pixel-densities of modern sensors: today we’re more talking about using 1/200 sec on a macro lens of 90-105mm focal length. With 36MP, 42MP and 50MP full-frame sensors as well as 24MP APS-C/DX sensors it is increasingly hard to achieve really sharp shots devoid of (micro-)blur. Image stabilization of fixed focal lenses below 100mm length is an important move that reflects the development of ever-higher mega pixel count sensors. The official Tamron moniker for the new lens is “model F017” the old one being “model F004”. To distinguish the new version from the old I designated the new lens as “VC ii” throughout this review. The new lens is also compatible with Tamron’s new USB dock for fine-tuning AF and VC or firmware updates, called the TAP-in Console. Announced in February 2016, it’s already the second iteration of Tamron’s stabilized 90mm macro from 2012 claiming improved stabilization from a newly added XY-shift compensation and better weather sealing. The Tamron SP 90mm f2.8 Di Macro VC USD is a stabilized full-frame macro lens available in Canon, Nikon, and Sony A mount.
