Originally posted by junkbench As a permanent novice I hesitate to lend advice, but I do welcome you to the forum (I'm new also) and will say I started with a Pentax 50mm 2.0 and still love the lens to this day.
I purchased a “ME/SE” in 1979 - it was kitted with a ‘M’ 50mm F/2; the body became damp at Niagara Falls, but I still have the lens.
I purchased a “Super Program” in 1983 - it was kitted with an ‘A’ 50mm F/1.7; I used that as a pair for over 12 years.
These days I still have the “Super Program”, but the lubrication in the ‘A’ lens seems to have dried out,
so when I use the camera body today, I sometimes use it with the ‘M’ 50 F/2;
Yes, I have better lenses that would work, but I often use it with the ‘M’ lens ‘for old times’ sake’.
