Hmmmmmm m, we'll see.
 
arent the current ones good with tubes anyways?
Thats a good question Paul - it does look very intriguing, it would be good to do no stacking thats for sure, whether it will work for insects who move around a lot though, thats another question. Might have to do some googling on anyone who may have done this already

EDIT: Looks really good though the price is bit steep. Just checking other manufacturers...

The current TS-E90 can get around 0.6x magnification with 25mm of additional extension which is very usable for moderately sized subjects.

Macro lenses typically have very flat subject planes whilst TS lenses need a curved subject plane....there's a compromise in there somewhere unless Canon have found an innovative optical solution (assuming that this lens is more than a rumour).

shouldnt a good ts lens have a flat field? isnt that kind of something you would want in a ts lens
 
That's a [CR1] rumour, which means basically that somebody overheard it in a pub somewhere. Don't hold your breath.

For tilting that would certainly be preferable but shifting requires a curved field to facilitate stitching.....I'll try to explain but apologies if it goes wrong between my brain, my written version, your reading and then your brain.

A rectilinear lens is corrected so that all objects on a plane which is perpendicular to the lens are in focus. Objects on this plane but not on the optical axis are further away from the lens than an object in the centre of the frame.....in essence, the distance to off axis objects equates to the length of the hypotenuse. The rectilinear correction accounts for this increase by focusing the lens axis and its hypotenuse on the same plane despite their differing dimensions

With shift employed, the object that was on the optical axis (and at sharp focus) is now moved towards the edge of the lens' captured area but still the same distance from the lens as before (we haven't moved anything) and it's still in sharp focus. However, it's distance now equates to the length of the hypotenuse (it's further away) and objects previously on the opposite side hypotenuse are now on axis and closer. Internally focusing lenses change focal length, which changes image magnification and field of view and stitches would be distorted.

If you followed all that, Paul, then you have my permission to duck out of the washing up today.
