A very useful boost for my Tamron 24-70mm lens on my Nikon D850. Although there is a slight loss of sharpness, it takes very careful examination of the images to notice this.

It's great!I used the teleconverter with Nikon 300 mm/4 AFD on Nikon D80, D200 and D300. Majority of the results were crisp and sharp provided lens was stopped down to 5.6 and higher. At wide open images appeared a bit soft particularly at the corners. It works nicely with 70-200 VR. I failed to discover any notoceable flaw. I would be happy if the actual f value was displayed in the viewfinder. So far as I know, Tamron Tamron SP AF 1.4x PRO is the only pro teleconverter for Nikon AFD.

TC 1.4 works brilliantly with 90mm tamron and nikon 80-200 2.8 nikon. A friend tried it with his 80-400 VR and was blown away with the ease and quality of the convertor

Works with the Nikon 70-200 f/2.8 VR lens - the big $1600 one - even though Nikon will tell you only their TC will work with it. Make sure you get the grey Pro version (which I believe is made by Kenko but carries the Tamron label).

The SP AF PRO-series teleconverters, with a re-designed optical construction (4-group/5-element for 1.4x and 4-group/7-element for 2x), are designed to be used with lenses that are F/2.8 and of focal lengths of 90mm or greater. This would make the use of the SP teleconverters ideal for the Tamron SP90mm F/2.8 macro, 70-210mm F/2.8 and 300mm F/2.8. Relative illumination is significantly improved resulting in better overall contrast and resolution across the entire image field. In addition, chromatic aberration and astigmatism are better compensated for by virtue of the use of higher-grade glass materials and more sophisticated design techniques than used in universal-type teleconverters. When used with lenses with smaller maximum apertures (F/4 and F/5.6, for example), there will be little difference in image quality as compared with the standard Tamron teleconverters. When used with lenses wider than 90mm, the SP teleconverters can actually comprise image quality.Compatible with Nikon DSLR cameras.
