🙂 mfogiel beat me to it; though the goggled Summaron can be used on M2, M4 etc., it makes most sense on a M3 which otherwise would not have 35mm framelines.
But you could try it out, at that price you would in all likelihood not have any trouble to pass on the lens for what you paid if you find out it is not for you.
I like my (M2-version) Summaron f2.8 very, very much. If you can live with the speed, it is a fine choice. You will not need a lens shade/hood in every day use, because of the recessed front element. Used in such a way the Summaron is more compact than a Summicron-C or Rokkor 40 f2.
