Attached is a photo of my Zeiss ZF Milvus 85mm f/1.4 lens on my K1 camera. It's
the highest rated Zeiss lens that can be adapted to the Pentax K1 camera.
This was the 16th Zeiss lens I've converted to Pentax K mount with a Leitax adapter. It was the most difficult conversion I have done so far. It took me about 3 times longer to convert this Milvus lens then other Zeiss "Classic" lenses I've converted.
The first photo I took was my wife's face. Attached is a 100% crop of her eye. I was very impressed with the sharpness of this photo - especially when considering it was hand held at f/1.4.
The weather is finally getting better here, the grass is turning green and a few of my spring flowers will be in flower next week. I will try to post some outdoor photos in the next few days to show you more about the capability of this lens on the K1 body.
