The Tamron 17-70mm f2.8 lens is supposed to have a busy bokeh (also named nervous bokeh) and an onion ring bokeh.
Let’s take a closer look at the bokeh quality of this Tamron lens…
Most of the shots were taken with an open aperture of f2.8, the rest were taken with f3.2 on a Sony a6100 APS-C camera to test the bokeh quality. A quite similar Tamron lens exists for the Fuji X-mount with the same image quality and bokeh. Check the details about this lens on the Tamron product page.

Tamron 17-70mm f2.8 alphabet soup “Di III-A VC RXD”
Tamron always likes to make its own alphabet soup: what does it mean when it comes to the Tamron 17-70mm f2.8 Di III-A VC RXD lens which was Designed in Japan and Made in Vietnam?
Di III: Digitally Integrated, according to the Tamron glossary, a lens engineered specifically for mirrorless cameras. Conversely, Di II would be a lens designed exclusively for use on digital SLR cameras with an internal mirror box or pentaprism.
A: APS-C lens.
VC: Vibration Compensation, in case of this 17-70mm f2.8 Tamron lens with an AI-based video stabilization system. When shooting video, image stabilization leveraging AI technology will automatically perform the best compensation for different shooting situations. The lens does Machine learning inference as process of using a pre-trained ML algorithm to make predictions for the best type of optical image stabilization.
RXD: Rapid eXtra-silent stepping Drive, referring to their something extra drive for a fast and quiet autofocus.
In my opinion, the modern Tamron lens does not come close to the beautiful bokeh with the “character” of the classic Carl Zeiss Biotar 58mm f2 and Flektogon 35mm f2.8 classic lenses, but for a modern zoom lens I have to pay respect. In my use case of photographing classic cars, I have no problems with busy or onion ring bokeh.
