That's what I'm concerned about--the benefits of a wide frame vs. distortion. But judging from what I've read, the Optar 8mm has very little distortion. Yet--it may be 'too wide' all the same. Will a 9.5mm lens get me a nice frame in a small car...or worse, in a crammed backseat of a small car? Ideally, I'd like to test the two lenses out and see for myself but I don't think that option's available. Does anybody have experience w/ these two lenses, specifically Optars, in these types of situations?
Cheers,
