Yeah I have spent most of my time with photography with 1 lens, because I'm not really as into the gear as much as the process. But weddings are different. There's so much going on, and so little time, I really will take any advantage I can get. I do use flash, and it's nice if it's done right. But it's also great not to have to use flash, or not have to use as much of it, and the super shallow depth of field look is really in right now, I've actually had brides ask for it. I'm not really into the idea of creating it with photoshop.
But here's a scenario, a wedding I recently shot. It was lit almost exclusively with candles, the ceremony and reception were both after dark, and the ceilings were 40 feet tall and painted brown. That's too much even for f1.4, I just had to blast a couple flashes all over the place.
But low light is romantic, so wedding receptions are often pretty dark. I don't really like going past ISO 4000 or so cause it doesn't look so hot even with the D3.
I'll be fine of course, and get the 35mm f2 or just use my zoom. I'm just surprised because Nikon's pro customer base are people who shoot fast, low light situations like photo-journalists, sports photographers, and wedding photographers. Canon I feel has positioned themselves for the studio and landscape, architecture, etc photographers. A really fast 35mm prime is the staple of photo-journalists and wedding photographers, and for Nikon to be behind canon there is a pretty bad business move. I mean with 1.4 canon makes up for the extra stop or so nikon has with ISO performance. I also have been a little annoyed with them for being behind with video, because I had to get a 5dmkii for video, and then I have to get twice as many lenses. I think Nikon should have released a D700x with 1080p before last christmas.
But yeah, I was joking about switching to canon for photography. the D3 is the first digital camera i've fallen in love with
