Q: 6. I love Zeiss lenses & currently own milvus 25mm & APO Sonnar 135mm lenses. I currently have Sigma 85mm Art lens & thinking of buying a Milvus 85mm or Sigma 105mm Art lens & sell 85mm Art later. I shoot portraits using live view, so manual focus is not an issue. From purely optical quality perspective, which lens is the better in terms of bokeh, color, micro contrast, sharpness an subject separation ability?

A: My recommendation is to rent the lens and compare. Many of the attributes you call out are subjective and cannot be measured / compared between brands. The only way to know for sure is a side-by-side comparison using the same camera, lighting and subject matter.

Q: 9. Can I use LEE Filters Foundation Kit with the LEE Filters Adapter Ring 95mm for Foundation Kit. Has it vignetting? Thank you.

A: You cannot use the Foundation Kit (100mm filters). It's too small for such a wide angle lens. The LEE SW150 II (150mm filters) system works perfectly. I use the SW150 II filter holder and 95mm screw-in style adapter ring (sold separately) with this lens. It works perfectly. There is no vignetting at all. I use 150mm NiSi filters with this system. They fit fine, and the filters are of higher quality. The downside of such a large filter system is the high price and the amount of space they take up. The image quality you can get out of them with this lens though is unparalleled. Hope that helps.

Q: 10. Is this manual aperture

A: No, the aperture on the ZEISS Milvus 50mm f/1.4 ZE Lens for Canon EF is controlled from the Canon camera body.
