What lens are suggested on D7100? I want to use it for basal pre-wedding photos?

HI

I'm a new shutterbug. Now I have a Nikon D7100. I want to use it for pre-wedding photos. Can anyone give me some suggestion which lens I could use. Also I saw a lens, Z14-30mm. Can I use it on Nikon D7100?

Your manual has an entire page telling you which lenses can be used with your camera, but any lens with a, "Z," prefix won't fit, as it's designed for the Z-series EVILs.

"Basal " pre-wedding photos?! In Britain and Australia I have shot many weddings but I have never been asked for "basal" photos!

Oh, did you mean "basic"?! Get your use of language right before branching out into photography!

Is this for a one-time shoot or for a profession?
For a one-time shoot, the 18-55mm kit lens if you have enough light.
For a profession, perhaps some of Sigma's ART lenses sporting a max aperture of f/1.8 (18-35mm comes to mind) or f/2.8 (24-70mm comes to mind). You may need something longer, so perhaps an 70-200 f/2.8 lens. With these 3 lenses, you'll cover most of your needs. You may want to throw in a 100mm macro for ring shots. Or, get a 60mm macro for ring and portrait shots.

Don't forget lighting and learning how to use bounce lighting effectively.

All of the Z lenses can only be used with Nikon Z mirrorless cameras. They can't be used with any DSLR because the required distance between the flange of the lens and the plane of the sensor must be shorter than what's possible with a DSLR.

For weddings, look at a lens like the Nikon 24-70 f/2.8 or something like it that has an aperture of at least f/2.8 with image stabilization. You'll need image stabilization for when taking shots in doors without a flash which is now very popular as opposed to using a flash. Problem with that is that IS allows for slower shutter speeds which will often result in motion blur with moving (e.g. Dancing during the reception) subjects. For this reason, you'll need an even faster lens such as the Sigma 18-35 f/1.8 or a 35mm f/1.4 prime.

35mm 1.8 / 50mm 1.8 / 28-70mm 2.8 …

Since you gave us no budget, I'm going to suggest what I think may be the best: the Nikkor 24-70mm, F2.8G. It gives good low light performance, is sharp and provides a decent zoom range.

If you are on a tight budget, the 35mm f/1.8 lets you get indoor portraits.
