I tested the AF-S Nikon TC-17E II teleconverter on the new Nikon AF-S Nikkor 500mm f/5.6E PF ED VR lens and the results are remarkable. This configuration results in a maximum aperture of f/9.5, but my Nikon D500 camera body had no problem acquiring Auto Focus. This overall configuration results in an effective focal length of 1275mm. All the photos below were taken hand held.
I recently found out about an opportunity to photograph military jets in flight, but my 70-200mm f/2.8 lens wouldn´t be adequate. It was suggested I use a teleconverter. So I bought this one, and I have not been disappointed. It reduces the maximum aperture from f/2.8 to f/4.8, but in bright lighting conditions, that´s not been a problem; plus the lens´s VR function really helps with motion blur. Images are nearly as sharp as without, and of course my new reach is 340mm. I´m very well pleased.
I bought a TC-17E II as a used product from a respected online vendor. After using it with my Nikkor 200-500mm zoom lens for a bit over a year I came to the conclusion that perhaps the converter needed to be serviced, so I sent it back to Nikon and they found the converter to meet factory standards, though they did clean it up.
The Nikon lens compatibility guide shows that the 200-500mm lens is not compatible for autofocus. I tried manual focus for several photos. I did get some good results, but they seemed inconsistent with distance. I got decent results for nearby subjects (roughly 15-25 feet) but unsatisfactory results for 100-200 feet in manual- or auto-focus.
I notice that others have had good results with different lenses. I suspect that with practice and careful exposure one might get better results with this converter/zoom lens combination. I´ll keep trying.
I´ve been using the TC-1.7 for some months now. I am more than happy with the product. I use it for bird´s photo on a 600 mm and 300 mm lenses. Yes you do loose some f/stop but in sunny conditions, it is not a problem. I adjust my camera to a slower speed shutter and higher ISO and I am very happy with the results. As far as the bokeh at f/4 goes, I loose nothing.
For quality loss, you indeed loose some quality but since I do not work for the National Geographic, the slight loss of quality if very acceptable considering that I´ve added 400 mm on my 600 mm lens or can go around with a lightweight 510 mm f/6.4 (300 mm x 1.7).
My experience with the 1.7x and my 400 f2.8 resulted in less accurate and slower focus tracking (D610), and compromised sharpness. The 400mm was sharper (when cropped) and faster without the 1.7x converter. I returned the 1.7x and had terrible difficulty with Nikon´s insistence on complete, original packaging. It was generally a negative experience. My 1.4x was better but the 2x was equally poor.
Have used this teleconverter extensively with my Nikon 300mm f/2.8 and my Nikon 70-200mm f/2.8, with no issues in very rugged conditions. It is my go to teleconverter for my 300mm lens when my 600mm is not with me. Never been disappointed.
I use this Teleconverter it mainly on my AF-S Nikkor 300mm f/4 PF ED VR and no noticeable drop of image quality. VR working very well. AF works fine, maybe a tiny bit slower. Compact light and fast.
I have the TC 1.4 ii and iii as well as the TC 1.7ii and TC 2.0iii I use the TC 1.7 ii with my Nikon D810 and 300mm f2.8 vrii. I regard the D810 as the best multipurpose camera ever made by Nikon as well as the 300 f2.8. The 300mm f2.8 is on the short end of the telephoto´s and lack the reach of the long once especially for bird photography. This is why I use TC´s as the lens is very easy to handle in a SUV that I use most of the time for our wildlife photography. The TC 1.7 was the black sheep of the TC´s in my bag until a recent trip where I decided to test it extensively. The focus is very fast, the IQ very good and you have to be a pixel peeper to notice and loss in sharpness. The TC 1.7 is a very underrated tool and works exceptionally well with f2.8 lenses. I have used it with the 300f4 and 70-200f4. in good light it performs very well but have an impact on the focus speed. For what it was designed to do, it is an exceptional piece of glass.
I have used this for several months with a 300mm 2.8 lens and a 70-200mm 2.8 lens. I photograph lots of birds in flight and have found little or no loss in sharpness of the image. I have to believe people who find problems with teleconverters may have other issues.
