Samyang has announced that it will be making five full frame lenses in E mount, which will be available within 2 months. The lenses are all based on existing designs, namely the 14mm f/2.8 ED AS IF UMC, 24mm f/1.4 ED AS IF UMC, 35mm f/1.4 AS UMC, 85mm f/1.4 AS IF UMC, and the T-S 24mm f/3.5 ED AS UMC tilt-and-shift. All feature manual focus and aperture operation too. As these are essentially SLR lenses with an adapter tube permanently fitted, they won’t offer any of the size advantages achievable by ‘native’ lenses.
