In this paper, we use Reissner-Nordstrom-de Sitter and anti-de Sitter solutions, where torsion $\\tau$ is added as an independent field, to analyze the weak deflection angles $\\hat{\\alpha}$ of massive and null particles in finite distance regime. We then apply $\\hat{\\alpha}$ to determine the Einstein ring formation in M87* and Sgr.
