Hello there... My brother brought me Leica to m43 adapter by Panasonic. I also have Pentax K to Leica adapter by Novoflex. So, I took my A 50/1.2 for a walk today. It turns out that infinity focus is at about 15 m (beyond 10 m mark on lens focus scale, but quite far from infinity mark). This is not good, but beside that, pictures come out just fine.
Using this lens even at f1.2 and getting accurate focus is extraordinarily easy... The view finder (being really nice and comfortable for me EVF) shows in-focus transition really clearly. Also, on-demand magnification and focus peaking help a lot. Here are some pictures to back up my words with actions: http://pentax-ways.blogspot.co.il/2016/05/2016-23-learning-to-ride.html http://pentax-ways.blogspot.co.il/2016/05/2016-24-dog-life.html Now, only if PDML elders would permit such a blasphemy and let me post PUGs or even for PDML annual... -- Boris -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
