Ive got bought the SLR Nikon d3000,i cant get it to take any photos,its says error no lense attached and it is attached and will only take photos in manuel mode and they turn out black??

Promaster makes many different lenses. Some of their older lenses do not have the electronics to communicate with newer digital cameras, and you have to shoot in Manual mode. Could you tell us which lens you're asking about?

For Nikon AF and manual focus SLRs. The compatible T Mount System makes it possible to use most any single lens reflex camera in combination with various front camera attachments such as telescopes, mirror lenses and slide duplicators. The T Mount is a metal connector that screws onto the compatible front attachment and allows this combination to be coupled to the SLR camera lens mount.

The Nikon lens, absolutely.

Quantaray makes their lenses with a variety of mounts. A lens with a Canon mount, for example, will not fit on the D3000. Assuming the lens has a Nikon mount, then yes, it will work with the D3000.

This problems sounds like you are trying to take pictures too close to your snakes. These lenses do have a limitation and usually you need to stand at least about 6 feet away from your subjects. If you are using a Macro lens then you can be closer; but the lens must be set to macro or have this feature. If you think you maybe having some type of focusing issue then I suggest you contact Photo Tech at www.phototech.com because they are the authorized Nikon service facility.

Good Luck

No. The converter is intended for certain point&shoot cameras. It is designed to fit in front of the much smaller lenses. The D3000 has interchangeable lenses, so you can simply remove whatever lens you have on it and attach a wide-angle lens.

Any of your lenses will fit on any Nikon digital SLR camera. However, there are several things to consider.

Most Nikon digital SLRs have a sensor smaller than a frame of 35mm film. This means that your lenses will give the same angle of view as a lens with a focal length 1.5 times longer. For example, your 50mm lens will give the same angle of view as a 75mm lens would. This applies to all Nikon dSLRs except the D700 and D3 series.

If the lens does not have the electronics to communicate with the camera, some dSLRs will not be able to meter with them. Of the current models, the D7000, D300s, D700, and D3 series will work.

Most old autofocus lenses will not autofocus on some dSLRs. Unless the lens is designated "AF-S" they will not autofocus on the D3000, D3100, and the older D40, D40x, and D60.

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.

The Nikon D3000 does not have a focusing motor built-in, relying on the lens to have a motor. The Tamron AF 55-200mm does not have the necessary motor; it only auto-focuses with Nikon cameras that have the motor in the camera body.

For Nikon lenses, you need lenses designated AF-S. For Tamron, you need lenses designated USD and/or BIM.

That probably wasn't the answer you wanted to see, but there it is.

This lens is too old for the D90, it has not got the electronics for metering and autofocus.
You can use it manually in M mode but you will have to set the aperture and shutter yourself.
The D90 manual has a section on compatible lenses, page 228 in my version.
This recommends CPU lenses for the D90, type G and D.

It is more likely that the tab has separated from the plate it slides on. The spring is attached to the plate with the tab sticking out from it. I have repaired these in the past by boring a small hole in the backside of the tab and use a screw to re-attach it.
