Introduction:
In common lens adapters, cropping effect occurs in all APS-C digital cameras with 1.5x magnification. This adapter reduces focal length to 0.726x , to adjust the image size to near 1:1 so that the focal length of the image is close to actual focal length of the lens, e.g. 50mm x 1.5 x 0.726 = 54.45mm for APS-C camera, and about 1.44x in 4/3 sensor.
Allows focus infinity. Switching camera to "Shooting without lens" mode is essential.
Feature:
- All metal structure, with excellent opticals (4 elements/4 groups)
- Reduce the focal length (by 0.726x wider)
- Effectively increases the maximum aperture of the lens by 1 stop (in other words, under the same aperture, you can use faster shutter speed (by 1 stop).
Notice:
1.Blue spot will occur if lens is shot to sunlight or lamp directly.
2.It cannot be used in EF-S lens.
3.There is no electronic integration, no auto fucusing, no auto aperture
4.if your lens has extended protrusion on the rear, please be careful, as it might get in the way with the opticals inside
