If it is good enough for Artie, then it is good enough for me. There were some good points in Artie's posts and his Q & A. I didn't know he was using Nikon equipment now. Is he no longer associated with Canon. I used to attend his seminars that were sponsored by Johnson Photo Imaging here in Bradenton, FL.

I am adding the web address of a well known photographer who used to be associated with Canon. His name is Arthur Morris and he has a website called "Birds as Art". I have been to a few seminars of his that were sponsored by Johnson PhotoImaging in Bradenton, FL and also at the yearly convention of the Florida Council of Camera Clubs. I pretty much take his word as gospel. His web address for his discussion on TC's is: http://www.birdsasart-blog.com/2018/03/01/nikon-af-s-teleconverter-tc-20es-suck-or-do-they/. Just click on the link. He shows some images taken with TC's on long lenses (but they are all "pro" lenses). I have regularly used TC's (both 1.4X and 2.0X) on my Canon 70-200 f2.8L IS. I have even stacked them both on that lens, but with both of them on there, quality suffers. Originally, I used the pro Tamron ones and they were slightly soft (I was a neophyte then when it came to TC's) but now I only use TC's from the lens manufacturer (in my case, Canon). My results have been similar to Artie's, but it took some time to find the best techniques to use. Read Artie's blog using the link and you can save some month's of wasted time. DO NOT use off-brand TC's if you want quality. Also, TC's are only compatible with certain lenses (and they are only "pro" lenses). You can damage lenses and/or the TC's if they are not on the compatible list from the lens manufacturer. I also always use a tripod with the 2X. I am able to use the 1.4X handheld for sports car racing and rodeo photography with good results.

There was a great disturbance in the Force earlier this year / late last year. He sold off everything from Canon in a fire sale and changed over to Nikon claiming their AF system is superior, giving him a higher percentage of keepers for his style of shooting. There was speculation there was more to the story, particularly his business relationship with Canon. If you go back far enough in his blog, you should be able to find the discussion.

In defense of TC's, here's a quickie unscientific comparison using a Nikon D850 with a Nikon 400mm f/2.8 with and without a NikonTC-14E:
Image 1: Shot with 50mm lens to put things in perspective. Distance to target 100 feet. The white bar code labels is what I'm going to look at.
While there may be some loss of sharpness using a TC, that is overcome by having twice as many pixels on target.

Interesting OddJobber, thanks for the post.

I routinely use Nikon's 300mm f4 VR PF and 200 - 500mm f5.6 with the Nikon 1.4x III teleconverter.
I've done the AF Fine Tune with both of these combos.
I get more than acceptable results in terms of sharpness with the 300mm at f5.6 net and little to no improvement by stopping down to f8.
I also get good results with the 200-500 at 500mm at f8 net. However stopping down further, to f10 or f11 gives noticeably better results.
I tried a used Nikon 2x II TC with the 300mm, was disappointed with the result, and passed on buying it. I haven't tried the newer III model.
