I own a Nikon D3100 DSLR camera and recently just bought a 650-1300mm Telephoto Lens for the Nikon. I've done everything the book said and then I went to use it and all pictures came out black...I can't adjust the exposure or anything, does anyone know what I'm doing wrong?
And before someone asks, yes the lens cap was off and yes the camera was on, yes the lens was attatched to the camera properly, yes I had it on the M setting (as the book said) and my pictures still came out dark. What am I doing wrong?
Answer
What you did wrong is not read the fine print or if you did, you did not understand what it meant in relationship to your specific camera.
* that lens is a stop-down metering, manual focus lens and it has NO CPU
* your camera is an entry level dSLR and uses Nikkor AF-S lenses if you want to use the auto-focus feature of your fine camera or Nikkor AF lenses if you don't mind manually focusing the lenses. In both cases, the meter on the camera will work just fine. BUT other lenses, especially very inexpensive, low technology lenses like the one you purchased cannot use the meter in your camera. You will have to use an external light meter and then manually set the cameras shutter speed, set the preset lens aperture to that indicated by the light meter, focus the lens and then move the lens aperture ring to the preset aperture setting. As you can see this is a very slow process, so patience is important
I suggest you return the lens and save your money toward a lens that will work with your camera.
The longest lenses made for current dSLR camera which are auto-focus are either lenses like the Nikkor 200-400 mm f/4 ($7,000) or Nikkor 600 mm f/4 ($10,300) As you can see there is a vast difference in the cost of a precision lens vs. a poorly constructed lens using decades old technology.
The best low cost telephoto zoom for your camera would be the Nikkor AF-S 70-300 mm lens ($590)

Is a basic DSLR camera better comapared to a camera like NIKON P510 having 42x optical zoom? Which one?
TUSHAR T.
Which camera is better in comparison with regards to the clarity of the image in the zoomed mode? And which of the cameras above can have the best zooming capacity (DSLR or higher point & shoot) ?
That is in comparison to a DSLR camera having 18-55mm lens.
Answer
DSLRs have a much higher degree of quality than compact cameras such as the P510.
Thing is, the higher power zoom lens you have, the worse optical quality it has. With a ridiculous 42x zoom, the optical inferiority is likely to be quite noticeable at different zoom settings. They are so mediocre, I just cannot understand why people do not realize this and continue to buy them.
In contrast, DSLRs - at least those with zooms, typically have lenses in the 2x to 4x range - but that is not to say DSLRs are limited in their zoom capacity.
I do have to back up here a bit and explain that generally DSLR owner's don't use the "X" factor when talking about lenses. They typically talk in focal lengths.
A zoom lens is one that has different focal lengths. But in the DSLR world, not all lenses are zoom as Jim pointed out. Some are fixed to one focal length (call them 1x zooms if you want).
But those lenses are absolutely the highest quality lenses you can buy, and are often used in Wedding Photography, Macro, and other specialized purposes when you need the best lens you can get.
Having said that, most DSLR lenses though are zoom. And since the lenses on DSLRs are interchangeable, the idea is to have many different focal length zoom lenses that collectively make up the total zoom range of the camera.
The reason for this is that the high optical quality is maintained by using multiple short zoom and fixed lenses rather than an optically inferior single zoom lens like the 42x lens on the P510.
Personally, I have 8 lenses - from 10mm to 400mm. Collectively, I suppose you could say that is equivalent to 40x in zoom power. The difference though, is each lens is many, many times more precise and optically perfect than the single lens on the P510. I just have to change lenses to do so.
And that does not happen as much as you might think as each kind of photography favors a different lens. If I am shooting sports, I don't need to take my macro, wedding, or landscape lenses - if I am shooting scenery, I will not be needing my sports or nature lens, and so on.
So I never need all 8 of my lenses at the same time - two or three at the most is all I ever carry.
In contrast, a single 42x lens is burdened with parts of the lens that will never be used at the same time - so you are sacrificing quality for a lens that you will never fully utilize.
Since you are comparing a DSLR with a kit lens (18-55mm), true - it will not have as long of a zoom as the P510 (18-55mm = 3x), but that lens will still be optically superior.
The reality of the situation is the 42x lens on a compact camera is a disadvantage, an no matter how much shorter the lens on a DSLR is - it does not matter - as the lens will be orders-of-magnitude optically superior. And if you decide you need another lens to cover a different part of the "zoom range" (to use compact camera terms), just go out and buy one. In that regard, "zoom power" is almost unlimited in a DSLR.
In the Nikon catalog, you can buy lenses from 10mm to 600mm, which is equivalent to 60x worth of zoom power. You just buy the segments of the "zoom range" that you want (and can afford). There is no compact camera that can touch 60x worth of high-quality zoom power.
