How to set up nikon d40 for use with a opteka 500mm lens with T-mounts and opteka 2x multiplier.


Answers :

You'll have to use the Manual (M) mode. You'll have to focus manually and the camera's exposure meter will not be functional. Since this is a fixed-aperture lens, you'll have to control the exposure with the ISO and shutter speed. You'll almost certainly need a tripod.

If you don't shoot RAW, you'll probably want to increase contrast and sharpness slightly to compensate for the lens's inherent softness.

The viewfinder of my Nikon D80 is grayish and blurry when it's off. I cant see a thing when I tried to use my 18-135 mm lens. I don't have a battery to reset it to its factory default settings. Do you think there's something wrong with the camera or the viewfinder is always blurry and grayish when it's off. I have owned D40 earlier and I could play around with the viewfinder even when the camera was off.


Hi,\015\012There is chance that your settings are just off . Set your settings to AUTO and then try again to view in viewfinder .If you sre still unlucky then there is some problem in camera ,You need to take to service center to get it service ... Nikon Digital Cameras

Just got a 500mm f8.0 Telephoto Lens for my Nikon D90. When I connect it according to the instructions I am certain I have mounted the lens properly to my camera, I have a universal T mount to connect to my Nikon. When I turn on the camera, It flashes in the top info LCD F- -, My thought is that this is the F-Stop or the Focal length which I will need to select on the lens and input on the camera somehow, am I on the right track since I am a novice. It will not take a picture through this len


The lens lacks the electronics to communicate with the camera. You must switch the camera to Manual exposure mode by turning the mode dial to M. The lens has only aperture, f/8, and so you have to control the exposure by changing the shutter speed an ... Nikon D90 Digital Camera with 18-105mm lens

I'm using a Nikon D3100 with a 55-200mm lens, and I'm trying to set my aperture around 1.8 to shoot bokeh, but it won't let me set it lower then 4. I had a 18-55mm lens on earlier, and it wouldn't let me set it lower then 5. My ISO is at 100. Any idea how to set it lower?


You can't set the aperture any lower than the maximum aperture of the lens. This is engraved on the lens. It may say something like f4-6.3 or something similar meaning that f4 is the largest opening of that particular lens. If you find a 55-200mm len ... Nikon D3000 Digital Camera

I have a Nikon D40 which is coming upto being two years old. Recently I have noticed that the auto-focus will not work. If I manually focus I can still take photos but when auto is engaged it will not even try to focus and therefore will not allow me to take a photo. I have not made any changes to the settings and therefore I am concerned it is a hardware fault. The lens in question is the standard lens supplied with the camera and is the only lens I have so have been unable to check t

Whenever I try to take a picture using "auto focus" option with my Nikon D40, (using the standard lens that came w/the camera), it makes a clicking sound and will not auto focus. But if I use it in manual mode it does not click. What could be the problem?


This camera focuses the lens by sending an electronic signal to it. If you hear a clicking sound, the lens is receiving the signal, but not responding. I suggest you take the camera & lens to a local photo store & ask if they could let you mount anot ... Nikon D40x Digital Camera

I was using my Nikon D40 at son's baseball game with the 55-200 mm lens & was too close to the fence when zooming since it tapped the fence. Now it makes a squeaky noise when trying to auto focus.

Hi. I use my Nikon D2x and 80-200 f2.8 zoom extensively, generally with a Hama cable release. Recently, the set-up stopped working. The camera focuses, but the release will not trip the shutter. The only clue (with a freshly formatted 16Gb CF card in use) is r17 in the viewfinder, although the manual fails to mention what this means. The cable release works perfectly on my D700 with the same lens. Anyone any ideas? Paul Perton Cape Town

I have a Nikon D80 SLR camera, and have purchased an Opteka 650 x 1300 mm zoom lens (fit on). I have changed the setting on the camera to manual, and it will now take photographs, however the images are very dark. Can you advise, as very limited instructions arrived with the lens. Thanks Bill


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 fa ... Nikon SLR D80 Digital SLR Camera Digital Camera

Hello, I recently bought a Tamron 28-300mm Model 185D lens for my Nikon D40. I can't get the Auto Zoom to work. I was wondering what I am doing wrong. is ther any setting I have to put my camera in? Anything I have to do on the lens it self? Help!!! Thank you Higor


Wont AF on a D40 as the D40 uses "in lens" focus motors. The 185D is a camera body AF drive lens. You need a DX type lens that has an AF motor in the lens for a entry level D40. Sorry. ... Digital Cameras

I have new Nikon D90 with 18-105 Nikon lens. The only problem with the camera, when shooting potraits in dim light without flash, the pictures get black artefacts throughout the faces and skins. I used different lenses and reset the camera setting to the factory original, but no help. Thank you for solving the problem... Hamid Jakarta, Indonesia


This has nothing to do with the camera, but instead it has to do with the lens you are using. The standard lens you are using has an aperture of f/4.5 which is common across many lenses. If you wish to shoot in low light you need a lower "f-stop". ... Nikon D90 Digital Camera with 18-105mm lens
