ultimate telephoto lens of 3.0 times high powered yet constructed in compact measurements of 92mm length (without Lens Shade) x 58mm outside diameter (at thelargest). Thanks to the State-of-the-art lens designing formula developed Raynox Tokyo Lab, the new 3-group/5-element construction of high index optical glasses reached up to a high image standard of 220 lines/mm resolution power at center (MTF30%) with three times high powered telephoto magnification. It never reached before.
