I'm curious if anyone has had the opportunity to test these two models out. I understand the 42mm will be slightly brighter, however I'm curious what the comparison is really like. I'd like to go and get my hands on some to test myself but, the nearest store is at least an hour away. I'm drawn to the 32mm due to the smaller compact size, but the 42mm due to the possibility of a brighter, possibly clearer, image. The spec sheet has the 32mm with a wider FOV, by only a couple feet. Has anyone had a chance to compare the two models?
