Tamron has patented a new lens for mirrorless cameras with APS-C-sized image sensors. If it becomes official, then the lens will have a focal length range of 18-105mm and a maximum aperture of f/4-5.6.
In recent times, Tamron was granted a patent for a 14-300mm f/3.5-6.3 Di III VC lens for mirrorless cameras with APS-C sensors that bears the description of a lens for DSLRs.
Either way, it appears that the third-party optic maker is planning to get really serious with the mirrorless industry, as it has just patented another optic for such shooters.
Curious minds have discovered a Tamron 18-105mm f/4-5.6 Di III VC lens patent, which has been designed for MILCs with APS-C sensors.

There are multiple versions of the lens described in the patent application. This could be a very heavy lens as its elements will always be divided into 12 groups. There are three versions with 16 elements and another one with 18 elements, all of them featuring multiple aspherical elements.
One model comes with a Low Dispersion element, two of them have a couple of Low Dispersion elements, while the 18-element version offers two Low-Dispersion element and one Extra Low Dispersion element.
These parts are here to raise the image quality of the lens by reducing chromatic aberration and other optical flaws. Regardless of its internal design, the lens will offer a 35mm focal length equivalent of about 27-157mm.
The lens is said to have an inner focus mechanism, which means that the lens will focus by moving a group of elements within the optic, so that the front element remains still.
Its description also includes Vibration Compensation technology, which will make sure that your photos will turn out blur-free.
Tamron will probably release only one version: the 18-105mm f/4-5.6 or the 14-300mm f/3.5-6.3
The Tamron 18-105mm f/4-5.6 Di III VC lens patent was filed on May 24, 2013 and it was published on December 8, 2014.
By the looks of it, this lens is close to being released on the market. However, the Japan-based manufacturer is probably considering its options.
An 18-105mm version would compete against the Tamron’s other patented lens, the 14-300mm, so it is very likely that only one model will actually become available.
This is all based on rumor and speculation, therefore you should not jump to conclusions, yet. Stay close to Camyx to see how this story unfolds!
