Look through front of wide open unmounted uncapped lenses -- clear view diameter should be identical in both lenses of equal f/#. _________________ ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮ like attracts like! ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮

Sigma 50 1.4 is completely different design from all old 50 1.4s. The sigma has so many optical elements inside and it is very huge. Also they say actually it is 45mm lens not 50mm.
Most of the old 50 1.4 are all the same 7 lenses 6 groups planar type, pentax have tried always to be the smallest which is not bad, but gives some problems - most of them are so small that the front element is not covered good so flares and lack of contrast are guaranteed without proper hood. I don't have an idea how the konika will behave and what is it's story. If it has that big front element i must be different in something. _________________ 10-300мм 4.0 - 1.2 - 4.5 NIKON&Sony bodies / Sony 10-18, Pentax 28 2.8 II, CZJ 35 2.4, Nikkor DX 35 1.8, Samyang 35 1.4, KMZ 50 1.7, FDn 50 1.2 L, Nikkor 55 2.8, Rokkor 58 1.2, Soligor 85 1.8 Preset, Samyang 85 1.4, Canon FDn 85 1.2 L, Tokina AT-X 90 2.5, Canon FDn 135mm 2.0, Nikkor 180 2.8 ED, Tair 300 4.5
