I loved the pre-Milvus version of this lens, but when I sold my D800 I had no place to use it. It did't work on my M240, it didn't work on my Fujifilm X-T1- a fact the Leica SL and Novoflex's active EOS/SL adapter changed.
And, sucker as I was for new, I picked up the Milvus version. It and the SL were made for each other. The union's perfection is partially skin deep. Both share similar anodising: smooth and semi reflective. Both are perfectly engraved. And both lack a few ergonomic polishes. The Makro Planar's helicoids are rouger than the previous classic ZE version. The SL's bottom angles can dig into the hip.
But what a combination. Thanks to great contrast and wide-open focus with automatic stop down (a la Novoflex active EOS/SL adapter) the combination work as well as they do on a Canon camera.
