Are there lenses to help the nikon d800 with low lighting?

I'm trying to decide if i want to get the canon 5d mark iii or the nikon d800. I know that the 5d is more versatile (being better with low lighting and aliasing) but the d800 has an overall better resolution (therefore better images). Also the footage of the d800 doesn't have to have a lot of post op work on it (5d needs it every time if you want your footage to look its best).so I'm partial to the d800, but are there lenses that can help with its low lighting or aliasing problems?

You really don't understand ANYTHING about photography, do you?

Where did you get the idea the Canon 5D Mk iii has better low light?

DXO labs shows the Nikon 800 with a significantly better low light capability.

And yes, you can improve the low light capability of any camera by using faster lenses.

By the way, aliasing on the D800 is not a problem, On the D800E, the anti-aliasing filter has been removed to allow sharper and better photos - not possible with cameras having an aliasing filter (such as the D800 or 5D Mkiii). This is a special option for those people that want it. And aliasing is easily fixed in post-processing.

So the D800E provides better photos but you need to post-process them.

Not sure what review you are reading, but it sounds like it has a lot of Canon bias. Any review that takes the special "feature" of the D800E and then characterizes the D800 as having an anti-aliasing problem is pure BS.

Low Lighting. What the hell do you plan to shoot. Both the D800 and the 5DmarkIII have darn good image quality to give even at higher ISO's

And seriously what do you plan to shoot… Rabbits in the wild at night. Look a camera needs LIGHT that is a fact. Any camera needs Light! There are a few ways to help in situations where there's little light. For instance. How wider the aperture of a lens how more light is let in. So zooms go up to F2.8 in the DSLR category. Primes, that is no zoom, can go up to 1.0.

And how wider the aperture how more light is let in. So how shorter the exposure time or how lower the ISO needed. You need to learn the triangle here, ISO - Exposure Time - Aperture.

Together they form the precise amount of light on the film or the sensor that you'll need for the image. If you change any one of those in the photographic triangle, lets say You shorten exposure time because you want to freeze the action by 2 stops, then you either need to widen the aperture 2 stops, raise the ISO two stops or a combination of both widen the aperture one stop and raise the ISO one stop.

Understanding the triangle is the trick to make the best out of your photography.

And one simple reality.light you need light. If there's NO LIGHT there's no picture. You can have a true dark room, have the sensor exposed half an hour and all you get to see is the noise of the sensor.

This by the way is how certain anti noise methods work. First they expose for the shot then they make another shot with the same exposure time but with the shutter closed. This gives them the noise said exposure would give and that they add to the Raw file or.process that directly in camera to remove said noise from the JPG image to be.

Eh aliasing wtf.both the 5dmarkIII and the D800 have an anti aliasing filter. Only the 800E has a slightly adjusted filter. But even there aliasing doesn't really happens much.

Hmm… There are so many lenses available in the market but don't know much about it. Just chk below link for your reference. Some lenses might help your requirement.

Not to be rude, but are you sure you want either of those cameras? The reason I ask, it that your question is a pretty amateurish. That's fine, not everyone can be a pro, or even avid amateur photographer, but you're talking about professional equipment. I think you will be in over your head with either of these cameras. There are so many different settings, that it's almost impossible to use these cameras correctly if you don't understand what makes them tick. I think you would be happier with a good consumer level camera like a D5100 or T3i until you get the hang of it. Both of these cameras have the capability to take you from beginner to advanced amateur, at which time you can start thinking about upgrading. If you start out with equipment that's over your head, you may very well end up frustrated because you are not seeing the quality you think a pro camera should give you, and give up the hobby all together.
