I built a somewhat heavy lens attachment that mounts to the filter ring. This is fine with my old 85mm f1.8 as the filter ring is directly on the lens body.
I recently got a 35mm f1.8 macro lens - here the filter ring is on the lens element that moves when focusing. As a result I cannot use my lens attachment (it struggles to move the element and causes a lens error.)
- Is there term which denotes whether the filter ring moves during focusing? (Is this implied by the "macro" notation?)
- Can you recommend for 35mm or thereabouts lens whose filter ring is fixed to the lens body? (Or at least does not stress the internal motor when focusing.)
