Now let’s talk about latest Tamron patent, Tamorin is working on 100-400mm F2.6-F8.3 for M4/3 sensor. After looking at the aperture range I am bit surprised, having a 8.3 aperture at 400mm end isn’t so normal and you need to have vast amount of light to get clear shots with your lens. But before we begin, I must tell you that I am not impressed with the aperture range of upcoming Tamron 100-400mm lens for M4/3 camera.
