Here’s another example, this time with a lens that has a bit more chromatic aberration in the first place – the Nikon Z 100-400mm f/4.5-5.6 VR S. In the chart below, the “560mm” entry refers to the 1.4x TC, and the “800mm” entry refers to the 2.0x TC:

Today, I’ll be reviewing Nikon’s first teleconverters for the Z mirrorless system: the TC-1.4x and TC-2.0x. These two teleconverters multiply your focal length by 1.4× and 2.0× respectively, with the usual loss of light. How do the Nikon Z TCs hold up in practice? I’ll answer in this review. NIKON Z 9 + NIKKOR Z 100-400mm f/4.5-5.6 VR S Z TC-1.4x @ 560mm, ISO 250, 1/2500, f/8.0 Keep all of this firmly in mind as you browse our guide to the best teleconverters, and decide which is the best option for your camera and lenses. We've split our guide into sections for each lens mount to help you find teleconverters to fit your system. Canon EF mount teleconverters Thank you for what is, by a long way, the most comprehensive and informative article I’ve seen on teleconverters. However, I think it could be even better with more reference to sensor pixel densities. I see that many of the shots illustrating the article were taken on 12 MPx cameras.Keep this in mind when purchasing a teleconverter, as you might need to calibrate it with the lenses you are planning to use it with. Reduced Autofocus Performance Increasing focal length can also magnify other variables, such as thermal distortion. That in itself can be a very frustrating issue to deal with in the field. This image shows quite a bit of thermal distortion, with thermal waves making parts of the image look very soft and mushy Some have physical limitations, such as a rear element extending too close to the camera mount, while others have optical limitations. Since most teleconverters are specifically designed for professional super-telephoto lenses, most wide-angle, standard, and telephoto lenses are not compatible with them. However, there are exceptions – some macro lenses, such as the Nikon 105mm f/2.8G VR, do work quite well with Nikon teleconverters. This time, the sharpness results are clearly worse, as expected. The results are still usable, but even the best-case scenario with the 1.4x TC is essentially “f/16-level sharpness”– fine in many cases, but nothing groundbreaking. Meanwhile, at 800mm with the 2.0x teleconverter, the results are acceptable in a pinch. But if I shot at 800mm constantly, I would definitely want to add the Nikon Z 800mm f/6.3 to my bag.

This Z 1.4× Teleconverter increases a lens' focal length by 40%, but also makes its maximum aperture one stop slower and requires a shutter speed twice as long or an ISO twice as high, or a combination of the two. Of course at smaller apertures it's all the same, but with long lenses we're usually shooting at maximum aperture to stop action and/or camera shake. It is important to point out that the above percentages are only for the center of the frame. If you look at the numbers, you will notice that the teleconverters impact mid-frame and corner performance differently. This is due to the fact that the extreme corners magnify lens aberrations heavily. In the case of the Nikon TC-20E III, the lens sharpness was much worse compared to the center at 43% sharpness loss. Teleconverters and coupling of several teleconverters: AF functions are disabled – only used with manual focus. And then I switched to the 2.0x teleconverter, making a 140mm lens with a maximum aperture of f/5.6: One thing to note is that teleconverters always change the balance of your camera setup by adding space between your lens and your camera. If you’re shooting from well-balanced gimbal tripod head, and you start swapping out teleconverters, make sure to re-balance your setup each time. The Nikon Z 2.0x teleconverter, side viewIt becomes compatible with the new tele converters once the lens firmware is updated to Ver. 1.02 or later. It won't work with older screw-type AF lenses; they'll be manual focus only, and it won't meter with any lens with an aperture ring.
