If the glass is flush with the mount there is nowhere for the teleconverter glass to go and so you are physically out of luck. Your lens must have a recessed rear element as pictured on the right. The rear element will also indicate if you can add a teleconverter.

If the number is higher keep reading for compatibility options. The maximum aperture is the f stop printed on your lens barrel indicating the widest your aperture blades will open. The first things to look at on lenses are the maximum aperture and the rear element. Not all cameras and lenses can use teleconverters. In general when using any type of adapter between your camera and lens you can expect a level of image degradation. Results will vary of course as these images were taken with some of the best equipment available. It’s apparent that there is not a big difference in quality If you really strain your eye you can see a few more details without the use of the teleconverter. Nikon 600mm Nikon 600mm + 2x TCIII (1200mm)īelow (left) you can see a 100% crop of the Nikon 300mm + 2x TCIII = 600mm and (right) Nikon 600mm. Here is a visual representation of the effect a teleconverter has on focal length. If you were using a 1.4x teleconverter you would only lose 1 stop of light (f/2.8- 1 fstop= f/4). It will also reduce the f stop of the lens by the same number, meaning a 2x teleconverter will reduce the aperture by 2 stops.

For example if you have a 300mm lens and you use a 2x teleconverter you have an effective focal length of 600mm (2 x 300= 600). The teleconverter multiplies the focal length of the lens. Nikon 2x Teleconverter Mounted Between Lens and CameraĪ teleconverter, sometimes referred to as an extender, is a magnifying lens that mounts between a camera and a standard lens to increase the effective focal length.
