Good build quality is distinguished from the converter. Even if the weight could be somewhat lower. I researched on the internet and compared with Raynox converter. According to various sources, and test images of the Canon converter showed the greatest sharpness and light sensitivity. Indeed, the sharpness is good and the photosensitivity is hardly attenuated. One drawback is the flash shadow of the built-in flash makes it unusable. For snapshots indoors the constellation compact camera + Wide is only conditionally suitable. Although it works with higher ISO settings without a flash, but it moves at the limits of decent exposure times. Remedy is only one external flash or studio spotlight. A plus is still no blackouts occur at the edges. Conclusion: Good converter for the G7.
