Thus, the lid does not sit in all the threads of the lens. At Tamron AF 18-200mm F / 3.5-6.3 XR Di II LD Aspherical [IF] MACRO the lid fits perfectly. The handling is simple and effective. With practice, there are very good values in the white balance. 1 * deduction because not suitable for my SIGMA lens.
