I have a D7000, 85mm F1.8 and Sigma 50-150mm F2.8. Im trying to build up the three most necessary lenses for wedding photography as I have three booked for the coming year so far.
I will add an FF body next year for lowlight performance (probably D610 for price) but im unsure whether id be better off with the standard zoom 24-70 for the FF or telephoto 70-200?
My concern is there here in the UK things can be pretty gloomy and a lot of venues wont allow ceremony for the flash.
I could sell the 50-150 for the 70-200 and buy a 17-50 for the D7000 or just keep what I have and buy a 24-70 for the FF when the time comes.
Which lens do you consider most important for the ceremony?
Thanks in advance
If you are serious about weddings then it is important that you have at least two cameras available in case one develops a fault.
Secondly, it is quite handy to have reasonable reach on one camera during the speeches and for other informal settings, plus your second camera with a wide to normal range.
Thirdly, as you say, often flash is not allowed.
So I would hang on to your D7000 and the 50-150. Maybe see if you can pick up a Sigma 18-50 2.8 HSM or 17-50 2.8 OS on eBay. (I used two of the 18-50 2.8 HSMs on D300s plus D80 for some time until I got a D600)
And for your future D610, the two options are probably the Nikon 24-70 f/2.8 or Nikon 24-120 f/4. I have used the 24-120 f/4 for a significant number of weddings on the D600 and have been delighted with the results.
The extra reach of the 24-120 is also very useful for capturing small groups of people during the signing of the register (In the UK we are not allowed to photograph the actual signing, although often that is not a restriction in church weddings) and during the speeches.
The D600 (and therefore D610) can easily be used at ISO 5000 or more, so in most cases, the f/4 maximum aperture is fine. The only thing to watch out for is when you come to doing group shots that will likely be enlarged a lot, use f/5 or f/5.6 - the 24-120 edges are slightly soft when used at f/4 with the longer focal lengths.
BTW if you get the opportunity, try out the D610 with your chosen standard zoom about half an hour after the sun has gone down, and the sky still has a bit of colour in it, and take some photos of the wedding venue. The sky takes on an amazing blue hue, and the lights from the building are often a magical yellow-orange. The D610 will be fine at ISO 12,800 with a bit of luminance noise reduction in Lightroom, so you should be able to hand-hold the shot... You will probably need to adjust the exposure to get the right effect - normal metering will create an image that is too bright. (Don't forget to set the camera back to normal exposure afterwards!!).
That image of the building can then be used as a background to other shots of people dancing etc. in the wedding album. In the UK summer the only downside is that it means waiting until about 10pm or later!!! Final thought here - the 24-120 has a slight advantage over the 24-70 for this type of shot - it has VR built-in...
Good luck!
