From recent reports it appears that Tamron has filed for patenting for new 115mm f/1.4 VC prime lens deign.  Details available from the patent filing #2016-151661 seems to suggest that the lens has a focal length of 113mm and a maximum aperture of f/1.456. The lens also seem to have internal focusing elements which means that the lens barrel will not extend when focusing and there will be vibration reduction.

Rajib’s love for the road is second only to his love for photography. Wanderlust at heart and a shutterbug who loves to document his travels via his lenses; his two passions compliment each other perfectly. He has been writing for over 6 years now, which unsurprisingly, revolve mostly around his two favourite pursuits.
