Are Tamron Lenses Compatible With Nikon

By | 16/10/2022

Nikon’southward first-political party lens support for its Z-mount mirrorless cameras has been growing rapidly over the last few years to nearly 30 optics. But to support that rapid growth, the company appears to exist purchasing Tamron designs and rehousing them to appear every bit Nikon originals.

Concluding nighttime, Nikon announced a new 17-28mm f/2.8 lens for its total-frame Z-mountain cameras. However, some have noticed that this lens bears a striking resemblance to the Tamron 17-28mm f/2.8 for Sony Due east-mount cameras that was originally launched in 2019.

On the outside, the lenses look to be about the same size and shape but accept conspicuously different branding. Since the Tamron lens was originally made for East-mount, the dimensions and weight do differ from Nikon’southward new lens. For example, the Tamron original weighs 420 grams while the Nikon version weighs 450 grams.

While some outside changes are to be expected, the interior appears to be unchanged. Comparing the optical arrangement of the interior arrangement of glass optics, the two lenses look identical. Both have the same 13 elements in the aforementioned xi groups.

The similarities are farther exemplified afterward examining the MTF charts, which also appear to exist extremely similar, if not identical:

This isn’t the start time that Nikon has been accused of rehousing what was originally a Tamron lens. Terminal twelvemonth, Nikon released a 28-75mm f/2.viii that, similar the latest 17-28mm f/two.8, bore hitting resemblance to a Tamron lens that was released just a few months prior, the Tamron 28-75mm F/2.8 Di III RXD.

The two lenses have the verbal aforementioned 15 elements in the same 12 groups.

When asked for comment, Nikon provided the following:

“All lenses developed by Nikon are designed to satisfy the high-quality standards divers past Nikon. We refrain from commenting on products released by other manufacturers.”

This response is not all that surprising; it was unlikely that the visitor volition say annihilation further publicly given the sensitive nature of this topic. At this time, all anyone can do is speculate that these lenses from two dissimilar companies are in fact the aforementioned lens.

It’s non necessarily a trouble that Nikon is doing this, since these two Tamron lenses are not beingness fabricated bachelor in Z-mount, so it’s non similar Nikon is charging more than for a lens that could be purchased for cheaper (like a name-brand medication versus the generic on the shelf at Target). That said, information technology is pretty unusual to encounter a major camera and lens manufacturer lean on what amounts to a competitor in order to build out a robust first-party lens lineup.

Tamron and Nikon clearly have a pretty cozy relationship, illustrated non only by this arrangement where Nikon will simply rehouse a Tamron-developed optic but as well in Nikon’south willingness to work with Tamron equally an official licensee to its Z-mount, a fact that
confirmed before this month.

This also isn’t a situation that makes upwardly a bulk of Nikon’s new Z-mount lenses — quite the opposite, actually. Nikon is withal producing the vast bulk of its offset-party lenses in-house, leaning on Tamron in only a select couple of circumstances. That said, information technology’s unlikely this will be the final time this situation comes up.
