Thanks.
I am using the A50/1.4, though its often said that they are the same in optical design since the 7-element takumar.
The thing about these Pentax 50's are that they provide a lot for the price and has the qualities that I like about their lenses.
Generally smallish, well built, contrasty with rich colors and a good balance of bokeh/sharpness.
As for the adapter, its one of those cheap ones off ebay.
Do note some things about such adapters in general.
1. Make sure they have a pict where you can see the inside of the adapter mount area and see if there is any 'tension mechanism' to give a tight fit. (this mechanism is better on some makes than others)
2. Make sure the adapter is matt black on the inside to prevent reflection. (I had to paint quite a few of mine)
Ha..ha..
The A7/r sure opens up doors to LBA.
Thats the problem here.
Too many good 50's out there.
I was considering the FE55 but just committed on a Cron DR 50mm today.
I'm curious about the Leica 'look' and performance, though at the back of my head, I have doubts its 8x better than this Pentax 50/1.4
