This teleconverter is by far the best I've tried (including the MC-14 and FF TCs from Nikon, sigma etc on FF). I'm really impressed.

If anyone is thinking about it but has been put off by bad teleconverter experiences previously then think again. This one is different.

The following is a controlled test of centre and corner sharpness and field curvature... an image of an OS map mounted parallel to the camera sensor, taken with aperture wide open (f2.8 on lens, f5.6 effective with TC). Camera mounted on Gitzo series 3 tripod. Manual magnified focus. IMHO this is pretty impressive for any lens, regardless of having a 2x TC attached.

The image has not been cropped and so the corner sharpness here is the corner sharpness of the TC / Lens combo. Auto tone has been applied in photoshop post processing, but no other tweaks have been done to the jpeg straight out of the camera.

I originally thought there was a little softness, but after closer inspection this is actually just the ink bleeding into the paper on the map.
