Apologies for another "which lens" post but hey, that's what we're here for right? I've thinned the herd of lenses that either didn't get much use or I wasn't in love with. My only body is a GM1 that I use for work (architecture and construction) and family shots. Right now I've got the Rokinon 7.5FE that I use almost everyday. Quite handy being able to get an entire room in two shots. The 12-32 is functional and what I grab for out and about -flexibility and OIS make it handy. I also have a 42.5 f/1.7 that I really enjoy for portraits and tight framing. What I'm missing is a fast normal and fast wide. My initial thinking is that the 15 would cover both of those and essentially replace my 20mm that I enjoyed but parted with due to AF and it being taller than my GM1. My fear is that the jump from 15mm to 42.5mm would be too much and leave me wanting. That and it's (for me) a lot to spend on a single lens. If I went with the 14/25 combo, I get the tiny and handsome 14 for a wide that's faster than my 12-32, and the O25mm which by most accounts is a stellar lens. My hesitation is that I'd either go 14 or 42.5, leaving the 25 little used making me miss out on the speed and image quality of the 15mm. After typing it all out I guess the question is whether 14/15mm to 42.5mm too big a jump in FOV for me. Would it be for you? thanks!
