I've managed to score tickets for a NYE fireworks display which will require a wide angle lens. I have the Oly 12 f2, which is certainly handy but in terms of focal length, the 7.5mm will probably be better from where I'll be positioned. So has anyone had a sustained session doing fireworks with the Samyang that may be able to pass on some tips? Considering it's fireworks we're talking about, I don't necessarily see the fastest f3.5 aperture being a problem and I'm not going to buy an Oly 8mm f1.8 just for one night. Thanks in advance!
