I have presently two:
Vivitar 19mm F3.8 62MM Filter thread
I bought this in 2000 new as it give a considerable wider field of view than a 28 or 35MM lending itself to creative shots. No:94102172
Tamron 28mm F2.5 49mm Filter thread. Type 02B No907710
I got this used in 1996 as I was not too impressed with some of the other MD fit wide angles I tried and didn't think Minolta's own though good were that great.
I really like this lenses resolving powers and the relatively bright image that aids focusing by hand.
