would it effectively turn my 17mm Tilt Shift into the 24mm - i know one is f/3.5 and the other f/4 but for all intents and purposes would this work?

Just going from memory here, but I understand that the Canon EF x1.4 and EF x2 Extenders only work with the family “L” lenses? Not too sure if it’s a select few “L” lenses or the whole range?

EDIT: Just to clarify, I am talking about the Optical Extenders that have glass elements, not the Extension Tubes that are basically empty tubes, which can be used with the TS-E lenses.

I believe it won't. On Canon's website a while back now, I read something about them only working on lenses with a minimum focal length of 135mm, or so. I know I also can't use extension tubes on my 24mm tilt-shift, I've tried, and nothing comes into focus at any distance from the lens.
Here is a screen capture from a Canon EF Lens Book I downloaded a few years ago, so I'm not sure if it is still valid?

Don't knowSorry, but I honestly wouldn't have a clue.
Please be honest with your Critique of my images. I may not always agree, but I will not be offended - CC assists my learning and is always appreciate

That is really bizarre, Dennis, because I can't get my Samyang tilt-shift to focus on anything with any of my extension tubes! I wonder what's different that allows the Canon's to work?Originally Posted by nardes

Doesn't that depend on where the extension tube shifts the maximum focus distance? the shorter the focal length, the closer to the sensor it makes the max focus distance, and you get to a point where the maximum focus distance is closer than the front element at which point you can't get close enough to focus?

That makes sense, John. Thanks for the clarification and explanation.Doesn't that depend on where the extension tube shifts the maximum focus distance? the shorter the focal length, the closer to the sensor it makes the max focus distance, and you get to a point where the maximum focus distance is closer than the front element at which point you can't get close enough to focus?
According to Keith from Northlight Images:

I'm sorta disappointed that I can't get them to work with my Samyang 24mm tilt-shift.
Looking at that chart, the long distance compresses a lot faster than the short distance... so maybe the issue is not that it gets closer than the front of the lens, but that when the long distance meets/crosses the short distance, the physics no longer works?
I presume you want the answer to your question, which refers to the 1.4x extender and not the extension tubes. It is - yes, you can. With some loss of quality. Try a search on canon 17mm ts-e with 1.4xextender and you will get some more info
