So in my ongoing struggles with GAS, I've realized I don't actually have anything wider than 14mm except my Bower 7.5mm fisheye. Which is a great lens, particularly for nature photography, but I'm planning on doing a lot more tripod-based night city/architecture photography this summer once the weather gets a bit more comfortable, and the distortion doesn't lend itself well to that kind of shooting... I had a chance to buy the Olympus 4/3 11-22mm for ~$200, and I let it slip through my fingers. I was wrangling with the size, and the fact that I'd need to spend at least another $50 for a4/3 adapter. And I'd heard misgivings about the corner quality on newer 16MP sensors. But now I'm thinking that it would've been just about exactly what I'm looking for. I like the idea of the Olympus M.Z 9-18mm, mostly just because of how tiny it is, but would the quality actually be better than the 11-22mm? Because the price is still trending over $500 up here (more than I want to spend), so even if I forked out $300 for the 11-22 + $50 for the adapter, I'd still be comfortably ahead, with a faster lens...and I'm not sure I need the ultra-wide end as much as I'd appreciate having the more useful normal end. (The 4/3 9-18mm is barely $100 cheaper, which feels like I'm giving up too much for too little difference). The other alternative is the Panasonic 12-32mm, which would end up being the cheapest and tiniest, but almost definitely the worst optically and not that much wider than the 14mm I already have. In the opposite direction, I'd be stretching towards the 4/3 Olympus 12-60mm, but I think that lens is just too big and heavy, is much closer to the $400+ range, and supposedly has complex moustache distortion at its 12mm end, which is again not that wide. So I'm torn. As you can tell. Insights? Anyone struggled with similar thoughts and budgets?
