1.4x Teleconverter HELP

[eddlum25]

I am looking for a 1.4x teleconverter for my Canon 70-200 f4 non IS lens and my Sigma 150mm f2.8 non IS lens. I am currently drawn towards the Kenko teleplus 1.4x 300 pro or Sigma 1.4x teleconverter. My question is does any of these lens fit on both of my lenses and if it fit does AF work ? If anyone can post their photos taken with the combination of these lenses will be much appreciated.Thank you

Sigma brand 1.4TC will fit the Sigma 150mm and will AF. I can confirm that (in fact its often how I use the 150mm with the 1.4TC attached).

I can't say if it will or won't fit the f4 lens nor how it compares to the Kenko

I have a Kenko 1.4 teleplus pro 300 for nikon and all my afs and afd lenses maintain full functionality. It even reports the reduced aperture and increased focal length in the exif file. The camera meters just fine with it on. I originally bought it to increase the image circle of my 17-55 AFS when mounted on my D700.
