the second one is okay, indeed, i dont like the first one tho.
i love street photography, btw.
but to do street photography, its to suggest to buy, in this special case, the right gear first:
street photography doesnt make sense bith a big ass slr, what you want is at least a good point and shoot, maybe one of the leica digitals or a nice kodak retina af or the ricoh gr, which make more sense, since street photography is grainy-black-and-white-ilford-film-photography with almost just black and white and only minor shapes of grey, or, to go the "true", classic way, the way you want, get a rangefinder, while it almost doesnt matter which brand, wheather its an old minolta himatic or a kodak retina rf, or a voigtländer, a zeiss or, and thats the high-class for everyone who takes photos, a leica, mp or m6, m7 pretty much sucks, too much automatic, or of course a leica m3, and my favorite, the voigtländer bessa r3a, since its the best right after the leicas (a matter of taste of course) at approx. 1/3 of the price (leica m6: ca. 1500-2000€, at least at an A-condition, while the bessa is 599€ new.), and before someone steps in: i know, the r3a also has automatic shutter speed.
take a look at this to get some inspiration:
