I really do like the lens, mine is everything I would expect in terms of performance.
I also have the 21mm F2.8 MC Rokkor, but the 21mm F4 feels a lot like a rangefinder lens in operation.
Really I am glad I have both of them, but I would recommend the 21mm F4
The 20mm F4.5 Pentax Takumar hood on mine has been replaced by the hood for the 20mm F2.8 MD Rokkor
Here it is on one of my Minolta SRM's

I had the f/2.8 21mm since the early 1970's and enjoyed it. It was a great lens. the f/4 lens if I remember correctly required the mirror be locked up. I much perferred the f/2.8 because I could see what I was going to get.
