TS-E 24mm II + 2x Mk III Extender

[87vr6]

Maybe instead of tubes, get the 45 or 90 ts/e lenses..

Great, thank you so much, neuroanatomist!!
In those pictures you can clearly see the drop in the IQ of 24mm ts-e so I guess it's a no-go.
I ordered the kenko pro 1.4x teleconverter instead - I hope it won't be worse than canon mk iii!

Higher mag than the native lens - up to 7x with the 1.4x TC and 10x with the 2x TC.

I've never owned a tilt-shift lens but did you mind explaining how the magnification increases that much rather than just 1.4 or 2x?

We were talking about the MP - E65,in regards to other lenses you could use extenders below 135L

Thanks my bad, I'd missed a MP - E65 had come into the equation and was wondering how an extender could increase the magnification of a TS lens 7 or 10x relative to original magnification.
