Depends on the lighting you'll be shooting in. If you're almost always going to be outdoors, the kit lens will serve you well.

If you plan on taking hand held shots indoors or at night - you'll most likely want a different lens.

I use a 35mm f/1.8 around my home pretty much exclusively. It lets in far more light than the kit lens, making it a far better choice to use indoors or at night time.

The other reason to get a faster lens? Bokeh. That beautiful blurry background/foreground effect.

I think most people on these forums would agree that if you're going to buy one lens beyond the kit lens, it should be a fast prime at a focal length you use constantly.

And not just a little bit faster. The 18-55, at 50, is pretty close to f5.6, if not already there. Which means that at f1.8, the 50 is over 3 stops faster. VR can make up some of the difference, but not for moving subjects.

The other thing is that the 35/1.8G and 50/1.8G (I have both) are undeniably very sharp lenses, right across the frame - better than the high class zooms for full-frame sharpness. This is even more important to me than the speed.

What else? Compact and light too.

Compared to the 18-55 in particular, they also have much better manual focus implementation (including no lens rotation on focus) and metal bayonet mounts.

ok thanks

but now tell me which is best 50mm lens?

1. 50mm (f 1.8)
2. 50mm (f 1.4)


other than bokeh effect and fast is there any difference between them in the quality of pics?

There is no best lens here, it all depends on what you want.

The 1.8 is a little bit sharper, especially in the corners wide open. Also it's half the price.

The 1.4 goes an extra 2/3 of a stop brighter with a bit shallower depth of field and minimally smoother bokeh.

It all depends on what you want and/or need. It's up to you. There are tons of comparisons on the web, with pictures videos and commentary.

I got the 1.4 because at that time there was no 1.8 G. Thankfully I was spared the agony of choice. But it is always like that when buying lenses... there is no right answer. Only your budget.

There is a 1.4 and 1.8 in the AF-S series, and a 1.4 and 1.8 in the AF-D series, and then there is the AI-S series, which has, at least, a 1.4 still in production. So, "which is best" can be a complex question, and can depend upon the conditions. I own the AF 1.8D, and the AF-S 1.4, and find each to be better for different things. The powerful focusing motor in my F6 will whip the 1.8D right quickly into focus, and the aperture ring allows me to use the 1.8D on a manual-focus FM3A, or with a Novoflex adapter, on my Canons. The 1.4 AF-S has a gasket at the base, which provides a weather-seal when used on my weather-resistant F6. The 1.4 lets more light into the camera, very useful at night. The lack of an aperture ring means I cannot use the 1.4 AF-S on a manual-focus camera, or with an adapter on my Canons, unless I am content with f/22.

At the time I bought my 1.8D, I was actually favoring the 1.8 AF-S, with the 1.4 AF-S a second choice, but none were in stock, anywhere. So, I bought the 1.8D. Then, a week later, a local dealer finally received two of the 1.4 AF-S lenses, and as weather-sealing was important at the time, I bought one of them, too, in spite of the focal length duplication. A part of me wanted to experiment with the AF-D and AF-S difference, anyway.


Sometimes, it makes no difference which I use, and the 1.8D gets the nod, simply due to its compactness.

So, neither of my two 50mm auto-focusing Nikkors is clearly better than the other. Then, there is my manual-focus 1.2 AI-S. I use all three of these, at different times, depending upon what I want to accomplish. Life is good! :)
