Mike, you’ve picked a good combo for a vintage film setup. It’s what I chose back in 1971 for an around the world trip. Back then I only paid $125 for the 3g with f/3.5 5cm Elmar. Managed to pick up the Summaron 3.5 and Elmar 9 cm to round things out. There’s a few images from that trip in my gallery here on RFF, must get around to posting a few more. Sure wish I’d had fast colour film back then, 80asa down a dark back alley with slow glass didn’t always work. Would have been smart to stick with tri-x, ah four decades of hindsight.
I never bothered with a hood for the Summaron, my copy didn’t seem to need it. Had the clunky Leica finder mentioned above and felt it spoiled the lines of the camera. Am now using the excellent Cosina Voigtlander metal finder.
Have fun with the 3g, there’s something special about using the tools of yesteryear to make images today. Have been giving mine some use lately and have several rolls of tri-x ready to dunk.
Cheers, Glenn
