Question about Nikon Zoom Tele 80-400mm f/4.5-5.6 D-AF VR (U.S.A.) Lens

1 Answer

Nikon AF-s VR zoom-Nikkor 70-300mm

I cannot get the focus ring to work whether or not I am in manual or automatic. My other lens work normally. I have a D-70, so now in telephoto I get blurry pix even on tripods. Is it possible that the focus motor is burned out? Bob

    Thanks, I am hestitant to take the rear of the lens as I can fly airplanes and other hi tech stuff, but they don't make a left handed monkey wrench, So I will take it to a person who could do that sort of work. Your answer sounds exactly what the problem is as if I turn the focus ring the focus is still stuck on somewhere but the acutal.

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.

Need information and Instruction Manual for a Vintage Bushnell 300mm camera lens


This is not a zoom lens, it is a fixed focal length of 300mm telephoto, so the focus ring will not slide back and forth, merely rotate. It is also manual focus. If you google it, you may find a manual, but doubtful - best bet is to get a book on basic photography and read up on telephoto lenses there.
Update - allegedly made by Tokina, so should be a reasonable lens.

I have a 70-300 mm for my E-520. It is barely a month old. If I focus manually, with the large 'grip' ring set at 300mm, the lens will only focus at 150mm even when focusing on a high flying aeroplane. In...


The lens is definitely faulty. Either return it to the retailer for an exchange/refund or send it to the manufacturer for a warranty repair. Of the options available, a warranty repair should be your absolute last choice.

What kind of device are we talking about here? Actually, it doesn't matter, since this type of problem almost always requires servicing. Servicing or buying a new camera is always a process you have to make the call on. Get an estimate from a camera shop, and go from there.

Sigma 70-300mm lens defaults to manual focus


It will default to manual through the viewing screen. It will only work on automatic, using the viewfinder. Make sure you also set the focal length (lens to shutter distance). You might also have a mf / af switch on the lens. This also only works through the viewfinder.

My camera lense will not focus automatically or manually.


There is no battery in the lens.  The lens receives power from the camera. Whether or not the lens is getting power, though, you should be able to focus manually.
When you say you can't focus manually, do you mean that you can't turn the focusing ring on the lens, or that when you turn the ring the image does not come into focus?
If you decide the lens needs to be repaired, I recommend sending it to Canon.  You can go to their website (canonusa.com if you're in the US), click on support, and follow the links.

Lens for Nikon D60


I will try to help you, but please understand that my experience is with Nikon film cameras. Assuming that the D60 works in a manner similar to a Nikon 35 mm body and that Sigma macro lens work like Nikon macro lens, you should be able to determine the usable subject to lens distance by experimentation. First, make sure the lens is in the macro mode. To do this you must set the auto-focus mode control to the manual focus mode (see your manual). On Nikon lenses, you must first set the focus ring to infinity, then move slider switch, which has two positions marked; "normal" and "macro., to the macro position. You should now be able to rotate the focus ring to the macro range. Use the zoom ring to zoom in and out and focus with the focus ring. The the range over which the lens to subject to lens distance will yield an in focus image will be rather limited and in the range of an inch or so to 6 or 8 inches.

Trouble focusing with sigma 70-300 DL macro super lens


It will not focus on anything closer than 5 feet.

(From Sigma lens literature)
Capable of macro photography, this lens has a 1:2 maximum close-up magnification at the 300 mm focal length. It's the ideal high performance lens for portraits, sports photography, nature photography, and other types of photography that frequently use the telephoto range. It also has a switch for changeover to macro photography at focal lengths between 200mm and 300mm with a maximum close-up magnification from 1:2.9 to 1:2. The minimum focusing distance is 1.5m / 59 in. at all zoom settings.

Nikon d50 and lens


I don't have this kind of camera myself, but on my Canon D350 there is a switch on the lens that sets manual/automatic focus. Mine is marked MF/AF ans is just a simple switch. Check to see if this might be the case on yours, too. Also check the contactts on the lens and camera to see if they might be dirty. And be very careful not to get any dust into your camera housing! -Chris
