I am venturing into new territory and looking at some Rollei 80s 135 film for my next order at Ag. Anyone have any opinions on 80s in XTOL please...I've been using XTOL lately with Acros with excellent results, but like the sound of the extra red sensitivity of 80s for use with a red filter to cut through haze and see whether I can get these dark skies and bright clouds I have seen in pictures on Flickr. Ideally, I'd be getting really high resolution/low grain, without losing tonality....is Rollei 80s XTOL 1:1 ok for this? As an additional film, what is APX100 like in comparison....I read that Rollei film is rebranded Agfa....are the two very similar? Thanks.
