This has been a question that I have been researching for quite some time, What kind of lens do I need to satisfy a client for a wedding photography event. What’s the difference if I choose from Sigma or Nikkor Lens? (As the Sigma lens’ are a lot cheaper.)
First, ask yourself what a professional would use to shoot a wedding or similar event. This is important to separate yourself from the professional who’s livelihood comes from his or her skill in using the very best equipment. Best, in terms of quality, is one of those things that people like you try to find a way around because of the expense. When you work as a professional, your equipment serves as the tools of your creativity. To consider inferior equipment based on cost is to limit your ability to provide the highest level of quality to your client. That’s putting it mildly.
What you should have to shoot a wedding: At least (2) camera bodies, primary and a back-up. You don’t mention the camera you are using, so there are some things you need to consider. You need to think about which cameras you will use, will they be full frame (or FX), or crop frame (DX), or both. The sensor crop will determine lens choice due to the "crop factor", or focal length multiplier. A crop sensor frame is smaller than full frame, requiring you to "multiply" the focal length by 1.5 to calculate "equivalent" focal length, or perspective. Ideally, you should have a fast aperture standard zoom lens, sometimes referred to as a "walk-around" lens. For full frame, a lens like the 24-70mm f/2.8 is a good choice. For crop frame, the 17-55mm f/2.8 is a good choice as it approximates the full frame equivalent focal range while it maintains the constant f/2.8 aperture. Next, you should always have a fast short telephoto prime lens like the 85mm f/1.4 for full frame, or the 50mm f/1.4 for crop frame as it approximates a similar perspective. Finally, you’ll want a fast tele-zoom lens like the 70-200mm f/2.8 VR, for use with either full or crop frame, one of the more indispensable lenses you could have in your repertoire. These lenses should be Nikkor lenses, if you shoot with nikon cameras. Next, you need light. I would recommend the Q-flash trio, from quantum, on a flash bracket. The trio is a hot shoe flash with more power, and a parabolic head and diffuser. It’s simply the best way to get good light at events.
That’s pretty much it, really, two cameras, three lenses, and a good on-camera flash with a bracket.
So put simply, you’d should have no more than 3 lenses: A wide zoom, 24mm (or equivalent) to short tele for moving around the event, capturing interest shots and candids. A fast prime, f/2 or faster, for low light and portraits, formals, creative shots. And a fast tele-zoom.
Important: Do NOT use slow lenses. You’ll notice I didn’t mention anything in the f/3.5-5.6 aperture range. The difference between an f/2.8 zoom, and an f/3.5-5.6 zoom is more often about $1000 or more, and the difference between shooting at ISO 200 (with little noise), and ISO 800 (more noise). Faster lenses mean cleaner images, in simple terms.
And I’ll tell you what a very good professional photographer friend told me. Don’t dilute the market with low cost, low quality work because you’re neither experienced, nor have the money to invest in professional equipment, just to occupy some spare time or fleeting interest in your life, all so that you can call yourself a "wedding" photographer. There is no "amateur" grade in wedding photography, no "beginner" fee to charge your client. If you’re not prepared for your client to pay you, at a minimum, $1,200 for a 4 hour event when you start, don’t even bother. Because there’s no way I’d pay you to shoot a wedding with a sigma lens because you can’t "afford" professional nikon glass. And that’s only because I know better. The problem with people like you is, your clients don’t. They don’t know that your not worth the time wasted. There are plenty of people [like you] who want to be professional photographers who can’t "afford" professional gear, but assume you should have the right to go out and do the work of a professional. We can spot you a mile away. These are the questions that if you have to ask, you need to STOP, go back to the drawing board, and research further on what you need to do a wedding photography event. Asking this question on yahoo answers is easy, because I just told you which lenses you should have. So technically, I answered your question. But thing is, most people who work as photographers never had to "ask". They took the time to learn photography FIRST. When you learn, you don’t have to ask………you’ll already know.
So please stop pretending you’re a photographer. If you have to ask what lenses you need, you’re at least 2 years away from trying your hand at shooting IMPORTANT moments in people’s lives for cut-rates because you have no skill. It really incites resentment in a lot of people who work hard at doing this.
In the end, you should do what you think is right. Or disregard this rant and do what you want. But if you don’t put forth the effort, you’ll never learn anything. So you know what lenses you should have, now what? What are you going to do with them? I suppose that’ll be your next question, huh?
