Going to San Fransisco in September this year and want to leave my heavier camera gear at home. I do not want to look like a tourist. What I would like to know from this forum what do you think about aquiring an Ricoh GR camera. Being a fixed 28mm equiv lens would it be OK for cityscapes etc? Would not mind having no viewfinder, can manage that. Your thoughts on this subject would be appreciated. Thank you.
