Question: Is this a good lens for a D800 and for wedding photography?
Document: as good as heavy and price; means Worth each cent. is clear that Nikon spend high tech in this peace of art.if ur priority is sharpness and high quality pics u are in the right way... if u want just good pics, u have other less expensive choices...I'll use this lens for wedding, portrait and landscape photography.
I use 90% of my photography with this lens, perfect for low light landscape wedding photography and more . .
)** Edit January 10, 2014 **Having spent the last five years in wedding photography and taking hundreds of thousands of images in that time (as well as some portraits and personal use), this lens (out of 8 in my bag) still accounts for nearly half of my "keepers" taken. I've collected and moved in and out of favoring primes during this time and my preferences have evolved such that I use the 24-70 so heavily because:1. Autofocus is super, super quick and accurate.
It's truly remarkable that you can get professional images at 24mm and at 70mm without changing the lens! Obviously, it doesn't do everything. We still use a 50mm prime for extreme low light situations but the 2.8 on the 24-70 is plenty for 90% of our wedding and portrait photography. I hear of photographers switching back and forth between cameras because it's quicker than changing lenses or others who do try to change from prime lens to prime lens during a wedding. After using this almost exclusively for an indoor wedding this weekend I feel confident rating it 5 stars.There are to many positive aspects to name so I'm going to mention the negatives and if they don't bother you much then you should buy it!
Other people of course have different cameras and different uses, but for mostly wedding and event photography, this has worked fine for me.I don't know much about Color Aberration, and I'm not the type-A kind of person that will go out and make a chart on the sharpness at each available focal length, but I can tell you that if you have the money to drop on this beast, you will be amazed, especially if you pair it with a higher end Nikon camera.
This lens is really a no-brainer. It's the best walk around lens you could have, if your serious about photography. The fast aperture, resolving and build quality are what makes this lens a winner. Yes, it's heavy, but there is not cheating physics when it comes to optical quality. I really don't mind the weight now. It's mounted on my D800, when I'm not using my 14-24 for work. Although it seems to be focusing adequately, at some point I may send it in to Nikon to have it calibrated  this this body.
I did not like this lens at first because I expected more sharpness for the price. However, after I started editing my work, I realized that this lens takes my photography on another level when it comes to sharpness, especially when used with the D800. I took photographs with flash at an event and was shocked how sharp the photos came out. It compliments the D800 nicely. What didn't I like about this lens? I could not find anything yet.This lens is worth the money if you are a professional that needs to have a great image to work with for clients.
As a wedding photographer, having this lens is a must. I know that some people preferred to shoot with primes since it has a better depth of field and you can open the aperture wider than this lens to allow more light to shoot on a low light situation.Well let me tell you this. I used this lens mainly for the ceremony itself, cocktail hours, reception and some of the formal group shots. It is 70% of the time sticking in front of my camera delivering sharp images (though it has barrel distortion at times but that can be fixed using lightroom lens correction) It is that good.
I bought this lens for my  D800. I thought I could use the lenses I had at home (e.g. an old 24-120mm by Nikon) but the camera is simply too good to be used with &#34;cheaper&#34; lenses. This lens is very good in terms of sharpness at the edges. It is still a bit soft at large aperture but it is noticeably better than all my other lenses. The lens is also extremely fast to focus and quiet. I am not a professional photographer and perhaps the cheaper Tamron would have been more than enough for me but I thought it was a bit stupid trying to save some money on a lens after spending so much the body of the camera.
It's truly a versatile lens and I'm very pleased with the results of my photos. The lens is a bit heavy and pricey but it's worth it considering it has an f/2.8. As most of the reviews have already stated, it is a good quality lens for traveling and for both landscape and portrait photography.
Answer: It's perfect for that.  It covers the D800 full frame and I've heard people refer to it as "the wedding lens".  I don't do weddings on a regular basis, but when I shot my niece's wedding recently, I used this lens almost exclusively.
