- Detailed TS-E17 review and reviews of Canon’s (2017) TS-E lenses.
- Using shift with extenders/teleconverters
- Using tilt with extenders/teleconverters
The TS-E17 does not indicate the presence of the teleconverter in the normal EXIF file data
It seems that although the Canon EF Extenders work with TS-E lenses they are not 100% supported.
Thus the EXIF data (and camera display) shows what the lens is set to, not the effective aperture. So to get an effective aperture of f/11 I set the camera to f/5.6 with the Canon 2x converter.
Note: the different versions of Canon teleconverter are listed in an article on our EFlens.com site
This with just the 17 mm

17mm shows correct aperture of f/11
and with x2 TC

17mm shows set aperture of f/5.6, not effective aperture of f/11
No sign of the presence of the TeleConverter in the EXIF data.
Not all lenses can work with an extender. The list on EFLens.com shows suggested lenses that will work.
