Hello, I'm considering augmenting my current suite of lenses (7-14, 14-45, 20, 45-200) with some more low-light capable glass. I really like what's possible with the 20 1.7, but am often frustrated that it's not quite wide enough (some rooms just aren't big enough to get far enough away), and sometimes frustrated that it's not quite long enough. The 14-45 should be the obvious go-to lens to fix that, but it's simply not fast enough and rarely if ever makes it into my camera bag for that reason. So, the question is, can anyone who already has the 12-35 do a test to see just how slow an exposure they can handle hand-held for low light at both 12 and 35mm, and in particular, can they test how much of an advantage the power OIS is? Can the stabilised 2.8 match the unstabilised oly f2 at 12mm, or the oly 45 1.8 for low-light hand-held shooting? (I use a gf1, so no IBIS). Basically, can I get good enough low-light performance with the new panasonic lens that I won't feel compelled to want three unstabilised primes?
