1000mm Mirror Lens Adapter with In-Body Stabilization for Handheld Mega-Zoom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard telephoto lenses with high magnification, such as 1000 mm, are prohibitively heavy and lack image stabilization, making handheld shots impossible without a tripod, while existing solutions like teleconverters reduce image quality and increase noise.
Innovation Solution
A camera system combining a 1000 mm mirror lens with a programmable 'dandelion chip' adapter that communicates focal length and aperture information for proper image stabilization and exposure, enabling handheld shots with Sony's focus peaking or Olympus's auto focus confirmation, providing up to 3000 mm effective zoom with built-in image stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If standard telephoto lenses with high magnification (1000 mm) are used, then magnification capability is improved, but weight becomes prohibitively heavy making handheld shots impossible
Solution Approach 1:
The system segments the magnification function into two parts: the 1000mm mirror lens provides base magnification, while the camera's digital crop/sensor positioning provides additional magnification levels (1.5x, 2x, 3x). This segmentation allows achieving ultra-high effective magnification (1500mm-3000mm) without proportionally increasing lens weight.
Solution Approach 2:
The patent transitions from purely optical magnification to a hybrid approach combining optical magnification with digital/sensor-based magnification. The camera's sensor can be positioned at different locations or use crop modes to provide additional magnification without requiring longer optical paths, effectively adding a digital dimension to the magnification capability.
2Measurement precision
If standard telephoto lenses with high magnification are used, then magnification is improved, but image stabilization capability deteriorates (lacks image stabilization)
Solution Approach 1:
The patent merges the stabilization function from the lens level to the camera body level. Instead of requiring the lens to provide stabilization, the camera's in-body image stabilization system compensates for camera shake at the sensor level, working effectively with the 1000mm mirror lens to enable handheld shooting at high magnifications.
Solution Approach 2:
The camera body acts as an intermediary that provides stabilization capability to the lens system. The in-body stabilization mechanism serves as a mediator between the lens and sensor, compensating for vibrations and enabling sharp images even when the lens itself lacks stabilization features.
3Measurement precision
If teleconverters are used to increase magnification, then magnification capability is improved, but image quality deteriorates and noise increases
Solution Approach 1:
Instead of using optical teleconverters that physically alter the light path and introduce quality degradation, the patent uses digital/sensor-based cropping and selection of different sensor regions to achieve additional magnification. This digital copying approach maintains image quality by working with the existing optical image rather than introducing additional optical elements.
4Stability of the object's composition
If tripod support is used for heavy telephoto lenses, then image stability is improved, but ease of operation deteriorates (slower setup time, less maneuverability)
Solution Approach 1:
The camera system provides self-service stabilization through its in-body image stabilization mechanism, eliminating the need for external support equipment like tripods. The stabilization function is built into the camera itself, allowing the photographer to maintain image stability while retaining full handheld maneuverability and instant responsiveness.

AI summary
This camera system comprises a novel or new combination of three elements or parts including a 1000 mm focal length Maksutov Cassegrain MTO or Rubinar mirror lens threaded to an M42 to Sony Alpha mount or M42 to Olympus 4/3 mount adapter, both with their own “dandelion chip”, programmed with the focal length of 1000 mm allowing for the only currently image stabilized lens of this length, also allowing the lens to communicate with the camera to allow proper metering and exposure as well as focus confirmation for faster, more certain sharp photos whether through “focus peaking” in the case of the Sony, or “catch in focus” and a confirmation beep with the Olympus, as well as 3 variable levels of zoom from 1500 mm to 3000 mm in the case of the Sony (incorporating both the crop factor of the sensor and the crop zoom push button feature) and 2× crop with Olympus.
