Tamron Adaptall-2 135mm F/2.5 Model 03B: A lightweight telephoto which uses two thick convex front elements to make this lens very compact. Off-axis coma is minimized by using a high refractive index lens element. Overall, this is a moderately compact lens which provides good but not spectacular overall optical performance.
