HDP-7700ES High Definition Super-Telephoto conversion Lens 3.0x
Finally, we are able to introduce an 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 the largest). Thanks to the State-of-the-art lens designing formula developed here in 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.
The Lens Shade and 5-adapter rings come with the lens as a standard accessory.
With the HDP-7700ES lens attached, there will be no influence on F number of the master lens.
The lens has a mounting thread of 37mm.
