18-200mm lens Nikon

It's not actually a telephoto lens, it's a telephoto adaptor. I have used something similar, though not this actual model, and only on MF lenses. Have you tried at all focal lengths of the zoom - it may only operate within certain limits. If it happens constantly, then you may need to switch to manual focus.

It should work with just about any lens, though it works best with moderate focal lengths (say about 24mm to 200mm). Its primary purpose is to let the lens focus much closer than normal.

When you say "no results," do you mean it's not letting you focus closer? Mount the tube on the camera, mount a lens on the tube, then focus the lens to its minimum focus distance. Looking through the viewfinder, move closer to an object until it comes into focus. Does it come into focus? How close? What lens(es) are you trying?

At longer focal lengths, when the aperture is smaller, and in low light, many A/F zoom lenses struggle. Is it OK outdoors in daylight ? If so, lens is OK.

Is this the 28-80mm G lens? I have had some experience with this lens and it has always been soft at wide angles.

The camera is unable to focus properly in low light at long focal lengths. You might have to throw some light on the subject with a flashlight until the camera locks in the focus or resort to focussing manually.

I have this same lens and it focuses at all focal lengths and with all settings except :"manual." Be sure that the setting switch on the lens itself is not set to "M" (manual).

Hi - I own this lens and it manually focuses at all focal lengths (hard to see at 18mm unless your subject is extremly close). You may need to get the lens checked. BTW - Mine was set as follows when I checked for you:

• D80 was "on"
• M/A
• VR = Off
• Normal (not Active)

Hope this helps!

For Nikon Digital SLRs there is a special line of lenses. Almost any Nikon lens will work on the D60 body, but lenses not specifically designed for a Nikon Digital SLR will lack some features offered by the body. Nikon D series lenses, that are made for the Nikon Digital SLR series, are fully compatible. Although, any lens, AI type thru D type will work.

One of the snags with Digital SLRs is that lenses designed for film cameras have different focal point characteristics, and therefore altered focal length when used on a digital camera.

A film frame is 24mm x 36mm. The CCD in a digital SLR (Charge Coupled Device, changes light energy into electrical energy, which is then recorded as a digital image file inside the camera) is not that large. So the light is focusing on a smaller area surface. This changes the focal length of the lens.

There are other undesireable effects using film camera lenses with Digital SLRs. One of the desireable qualities of old lenses is the cost. The D60 is a great camera. You lose some features with older lenses, but you still get the same image quality.

I cannot tell you exactly what zoom lens to purchase, because it's like you asking what car you should buy. There are too many variables to consider. Most pros carry the famous Nikon D 80-200mm F 2.8 ED, which is a pro lens, with big weight, superb optics, and no finicky soft spots.

It's clean all the way through the range, at every aperature. But the cost is high, probably more than you paid for the D-60 body. But if it were me, I'd spend the money.

I had this problem and just realised it today. I found out that it was a a settings problem. What I had done without realising was I had my "AE-lock" button functioning as "AF-ON" which meant that my autofocus would only turn on when I held the shutter half-way and pressed that button. Once I turned this function back to its original state of "AF-Lock" as opposed to "AF-ON", it worked fine.
My symptoms were: • soft mechanical noise when holding the shutter (i thought it was trying to focus but couldn't. I thought the mechanics for the AF were faulty) • Couldn't take photos unless they were in the set conditions (which makes sense because it was locked on a certain setting until I pressed the AF-ON button).
My camera is only a few months old so I wasn't convinced it was faulty/broken. Make sure you test all of your settings and go through each of them before you chalk it down to equipment error.
Hope this helps.

What is the focal length of your lens?

In order to work with depth-of-field, two things are essentially contributors to fully focused image without depth, 1) it depends on your lens focal length 18-70mm or 70-200mm, 2) your f-stop. 2.8 (large iris) or 30 (small iris).

Simply put, a smaller iris (>15 fstop) increases the DOF, or makes things in front-of and behind the subject more visible/clear. Larger iris (<15 ftop) reduces the DOF, or makes things in front-of and behind the subject less focused/recognizable.

There's quite a lot that goes in to DOF, so check out the link above for the details.
