Nikon D1 I have a Nikon D1 and two lenses. One lens is operating normally but the other, a telephoto, is causing the display to flash FE E and the lens will focus but not take the photo. I do not have a user manual so I'm wondering hoe to troubleshoot?

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.

If you're getting shadows on the bottom center of indoor photos when take with a flash, it is most probably due to the length of the lens on the camera.

A long, telephoto / zoom lenses will create the largest amount of shadow, while shorter and wide angle lenses will be least likely cast shadows. You can reduce the amount of shadow in pictures by removing the lens hood that may be on the end of the lens. The lens hood is to primarily to shield the lens from direct (sun) light, and probably isn't needed for indoor flash photography. Also, rely less on the zoom function of the lens on the camera and physically moving closer to your subject instead. The flash will need to provide much less light output and result in more flashes per battery.

You could use a separate flash - held off the camera so that the lens is not obstructing the light of the on camera flash. Using a Nikon Speed Light, you can set the on camera flash to provide a low output, that would be used primarily to trigger a Nikon Speed Light held by someone or arranged on another surface etc. Youtube is a great source for real life, practical "How To" videos for many operations of the camera and accessories.

I hope this was helpful!

All third-party lens makers make their lenses available with a Nikon mount.

Keep in mind that autofocus will only work if the lens has an internal focus motor.

it will mount fine, but I don't believe you will have autofocus.

You could use flash. Depending on distance, you might want to go with one of Nikon's add on flash units. SB-600 is very cost effective.

You could also buy the excellent f1.8 50mm lens that Nikon makes. It's about $120 new. It's a prime lens (no zoom/telephoto) but it is one of the best lenses Nikon makes. It works very well in low light. There are also some other large aperature lenses, but cost goes up as f goes down!

The best way to get it done right after you drop the lense is send it to NIKON NY . They put the lense on a resolution bench test and it make sure the resolution is great ,. This lense is very criticial and it is a must or your wasting your money . The reason is this ., The lense is a wide angle and sometimes photographers have probelms with 17-55mm lenses and sub mirror problems . So its best to be safe than sorry .

Yes and no. If it doesn't come with one, you'll need a T-adapter for Nikon in order to mount the lens (you can get one from Vivitar, as well as from other manufacturers). The lens is not an autofocus lens, so obviously you will have to focus manually. It's also a mirror lens so it has a fixed aperture. It's what Nikon classifies as a non-CPU lens, so you cannot use the D90's exposure meter. You will have to shoot in Manual mode.

Canon currently makes super Telephoto lenses from 300mm to 800mm and a number of zoom Telephoto lenses from 28-300 to 100-400. You can also special order a 1200mm lens from Canon at a cost of $99k! (There are only about 20 such lenses made so far.)

You can also get a 1.4 or 2x teleconverter to further increase the power of a telephoto lens. However, the cameras are unable to auto-focus when the minimum f-stop exceeds f/8, which can happen when you use one (or both) of the teleconverters on these longer lenses, so you have to manually focus the lens.

You can also get telephoto lenses from other manufacturers such as Tamron and Sigma that are built to work with Canon cameras. However, the Canon lenses are generally regarded as the best quality.

First the auto focus motor is in the body and not the lens so that will not be the problem. Unless you dropped the lens the problem is probably in the focus gear interface inside the lens ( it is stuck in the manual drive --that is why no autofocus-- and there is something preventing normal gear operation). Seems like a small problem but will require a look at the rear of the lens where the gear box is situated.
