Tamron is really focused on making E-mount lenses one after another. Here is the next 150-500mm f/5-6.7 FE lens they will announce on April 22. Specs:
- 25 elements in 16 groups
- minimum shooting distance 0.6m (wide angle) /1.8m (telephoto)
- maximum shooting magnification 1: 3.1 (wide angle) / 1: 3.7 (telephoto)
- filter diameter 82mm, size φ93×209.6mm
- weight 1725g
- tripod mount 155g.
