Soligor C/D Dualfocus f3.5/28mm & f3.8/35mm MC
Latest Review Posted Yashinon DS-M 50mm f1.4
I have the DS version which is definitely coated but likely only a single coat. It is well made and handles beautifully, though there are a couple drawbacks. It has no A/M switch, so it means you need one of the M42 > K-mount adapters that has the inner flange. Further, the pin on this lens is shorter than most, so you need to add a washer of some kind in order to make sure the pin depresses. I cut out a plastic washer from an old credit card. Be sure to leave the full opening, since the rear glass comes all the way to the back when focussed at infinity. (It might be possible to modify the lens and depress the pin, but this was an easier and non-destructive way of doing things.) With all this in place the lens does fully function and focuses to infinity. The lens only closes down by full stops: 1.4 > 2 > 2.8 > 4 > 5.6 > 8 > 11 > 16. The lens has 6 blades and minimum focusing distance is ~14 inches which means about 1:7.5 magnification. https://www.pentaxforums.com/gallery/images/30918/large/1_Yash50a.jpg https://www.pentaxforums.com/gallery/images/30918/large/1_Yash50b.jpg https://lh3.googleusercontent.com/Pl42y9eNp59N3r7dWTnYhs75K3vv0C5xN1ejdd02vzfwQsetCXANXIIu3ji6CmQzi4yA-VM9LUOYDY3Dz8Cc1g=w822-h467?.jpg As for performance, I can compare it to my Pentax A 50mm f1.4, and it compares very well. The Yashica is a bit softer a f1.4 and can have some green CA, but the bokeh at 1.4 is also a bit smoother. Once you start closing down, the difference...
