I am not sure it is zooming right. Seems it doesn't zoom very far.
How do you make it zoom better?
I can zoom something in from across the room but no farther than that, unless I get closer. I have the small lense that came with the kit.

Re: zooming of Nikon D40 SLR Camera
You need to be more specific about which lens you've got! I'm guessing you've probably got the 18-55mm which is the most popular lens to be supplied with the kits.
From what you describe, the lens is working correctly. The problem is the maximum focal length of the lens (55mm) is not going to give you massive magnification. (Basically, the bigger the number, the more powerful the zoom.)
The sort of lenses that you can snoop on someone from half a mile away are going to be 300mm upwards.
This is one of the reasons that you can change the lens on an SLR camera. Now you might ask, if that's the case, why they don't make a 18-500mm lens. The problem is that the bigger the range of the zoom, the more the image quality suffers, so you tend to find the zoom lenses go up in a number of steps.
If you need more magnification, the only answer is to buy a more powerful lens I'm afraid :-(

Any Nikon digital SLR will work with this lens. However, there are two things to consider.
On cameras other than the D700 and the D3 family, the smaller sensor will make the lens appear as a 105-315mm. On the D40, D40x, D60, D3000, D3100, and D5000 cameras, you will lose the autofocus capability.
I had a similar problem with one that I bought. and come to find out, the gears internally in the lens where broken. I would return the lens, and get another one. Also when you go to buy a lens for your camera make sure that you bring the camera with you to test the zoom before you buy it. Just FYI you also need to remember that with a smaller zoom your focus time will be slower, and it will take getting use to, unlike the larger zooms, you are trying to focus on a large area but being very detailed at the same time.
Yes, with caveats. The autofocus won't work on D40/D60/D3000/D5000. The metering may not work in all modes on all cameras. Since you didn't specify which camera, I can't give you a better answer than that.
I have 30-year-old Nikon lenses working fine on my D90, but without metering. And the old lenses date before the invention of autofocus.
You can't meter through that lens. If the images are too dark, either slow down the shutter speed or open the aperture. Keep going until the picture looks okay on the monitor. If you know how to use the histogram, that's even better. If you go too far and get images too light, reverse the process (faster shutter speed or smaller aperture).
If you have another light meter, you can use that to get a ballpark exposure to start with. Alternatively, take a reading with your other lens at the longest zoom.
hi ! iam too a D40 holder,u can opt for AF-s versions or HSM sigma,both of them autofocus on d40,can go for 18-200 AFs VR or if u need still longer end go for 70-300 but it is costly than the sigms 70-300APO DG HSM MACRO..,its a much better reviewed lens and dont forget the cost..anyway do some research before considering..good luck
You have named several excellent digital SLR cameras aimed at the top end of the amateur/semi professional market.
I have the Nikon D200 and have been very pleased with it.
As stated by JCDill, you must really decide what you want and can afford. The camera body you choose will commit you down one path or another. For example, if you choose Canon, only Canon or OEM (Other Equipment Manufacturers) such as Sigma lenses will fit your camera body. Canon have a good reputation for their auto-focus, while Nikon make lenses that are the envy of others.
If this is your first digital SLR then you might be best buying an entry level body with a multi-purpose zoom lens such as the Nikon D40. There is a lot to learn.
If you are converting from film SLR and already have a set of lenses, then the cameras you mentioned will probably be able to use your existing lenses (but this is less so with Canon than Nikon). I was ecstatic to disover that my old Nikon 500mm mirror lens works in manual mode (with metering displayed) on my Nikon D200 but would not work properly on my Nikon D70.
I hope this helps.
2) I do not understand your assertion that it automatically zoomed in. Zooming is a manual function. The automatic functions of your lens pertain only to focusing on of the subject so that your picture is sharp and ensuring that the correct amount of light is admitted so that you have a correct exposure.
3) Are you sure you were turning the zoom ring and not the f-stop ring? The zoom ring is labeled 200 on one end of the scale and 55 on the other. It is also the widest ring on the lens barrel. When you rotate it, the physical length of the lens will lengthen as you rotate it clockwise (viewed from behind the camera) and shorten as you rotate it counter-clockwise.
4) For reference, at 200mm the angle of view on your lens should be 10 degrees and at 55mm about 40 degrees.
Autofocus function on the D40 only supports lenses with the
AF-S feature, which have an autofocus motor built into the lens,
instead of using an autofocus motor drive built into the camera.
The Tamron lens you have, does not have a built in motor and
the autofocus function relies on the motor drive in the camera.
It will not work with the D40 or D60, but it will work with other
Nikon digital SLRs, such as the D80. Need to get an AF-S
type lens or upgrade to different Nikon digital SLR. Unless
you do this, you will have to manually focus the Tamron lens.
All of the Nikon DX (for digital) series lenses are also AF-S
type, so they will work with the D40, which is designed as
an entry level digital SLR, therefore it is intended primarily
for use with DX lenses, which are typically sold in a kit with
the D40. Most common one is Nikkor 18-55mm DX AF-S.
Other Nikon AF-S lenses made for film cameras (FX type)
will also work with the D40, but these tend to be expensive
professional models. DX series lenses tend to be more
affordable. You might consider the 18-200mm DX AF-S
as an alternative to the Tamron, but these are not cheap.
