Your tweets about your NEX have intrigued me a bit…I get tired of lugging my Nikon D90 around with my kids, yet I find the quality of most point-and-shoot cameras terrible…so the NEX seems like an interesting compromise.
The Sony 18-55 mm tele-zoom remains my favorite NEX lens for its flexibility. Given this, I would definitely buy the SLR Magic 35mm lens before Sony’s overly wide 16mm pancake prime. But the SLR Magic would not be a good choice as the only lens on a trip. It’s a fun and fairly cheap toy, not a real photographic tool.
