I didn't know that LV had more accurate exposure based on shifted images -- usually, more shift equals over exposure. I'll have to check this out in more detail.
I shot on tripod in LV mode, in Av mode. I find getting the exposure in the zero position to generally give the most accurate exposure, provided the final shot has most of the same geography as the metered/unshifted scene view.

Thanks! I just purchased the 17 TSE on Friday. Love it so far. Way better IQ in the corners when compared to my EF 16-35/2.8 II.
I also own the 45 TSE.
I own a 1.4x TE but its the first version. I will test the TSE & TE combo on my 5D mk II against the 17 TSE alone on my 60D body to see how the pics stack up. Of course the TSE & TE combo on my 5D mk II yields an equivalent 23.8mm view and the TSE on the 60D yields a 27.2mm view. That is quite a difference really, but it would be interesting to compare the overall IQ differences. Of course I will then have this nagging feeling that the new version of the Canon 1.4x TE (version III) will produce sharper images than my old 1.4x TE mk I.
I guess there are many test variables one could do with the 17 TSE, both versions of the 24 TSE, using a tele extender, etc on both full frame and crop bodies.

Congrats!
Please post some comparison pictures after you start doing test shots. Should be interesting to see how it looks with crop sensor as well as version I Extender.

Shifting in opposite directions may have opposite effect on exposure, one direction overexposing and the other underexposing, with the overexposing direction depending on camera model.

Ok, I have uploaded a zip archive of 29 images of my living room and back yard, shot with the SL1 + 17TSE, and for comparison with the 5D3 + 17, 5D3 + 17 + 1.4xIII and 5D3 + 24mk2. (there's one stray f16 misplaced file in the 5D3+17 folder, please disregard it as I don't want to re-upload the file). Yes the house is crooked so it's not a good test but I am too lazy to go out and do it again. Apertures at f4-11 in full stops. If you're really really serious, raw files are available upon request.
Depending on how bored I am this weekend and what I do, I can do something more "real". Give me ideas. Note that I'm trapped in suburbia at this time

Wow, thanks Stan!
Stunning home by the way. I will look at these files when I get a moment and report my findings.
I will also do my own test with the 5D mk II and the 60D as described in my earlier post.
I have rented the older 24 and 90 TSE lenses on occasion. The 24 was not that great in my book. The 90 is really nice. Fabulous food lens really. Several years ago I decided to buy the 45 TSE which I like although it has considerable CA when shifted to the extremes. This can be overcome in post of course. The 45 TSE is very versatile and works well with close focusing extension tubes.
It might be interesting to see how the first version of the Canon 1.4x TE performs with the 17 TSE though. I am aware that chatter indicates the newer samples of the TE are better...

Great stuff, Stan!
Here are some other comparisons between sensors.
I now know why so few people bother to take these comparisons -- it's a PITA in the field, juggling bodies!! My examples are all from the same vantage point, hand held.
First are three shots of the same scene with 1Ds3 21MP full frame, 1D3 10MP 1.3X crop (22mm equiv.), and 60D 18MP 1.6X crop (27mm equiv.).

Great thread!!!
I just did a quick test in my kitchen. First I mounted the 17 TS-E on my 5D Mk II with a Canon 1.4X TE (mk I) and then compared it with the TS-E mounted on its own using a crop sensor 60D body. I used the same focus (on wine bottle), same exposure and same white balance. Both shots were taken at f/11. The 60D RAW files needed to be run through Adobe DNG Converter first as I am not using the latest version of PS.
The color in the 5D shot seems a little better but that might be due to the DNG conversion. I did no other adjustments other than a little Unsharp Mask when sizing the pics for the web.
Results? I am sort of surprised at how close they are. I sort of expected the image using the older 1.4X TE to be softer, etc than the TSE on the crop sensor camera by itself. I have no idea what kind of benefit I would expect with a newer version of the 1.4x TE?
Here are the two shots and a 100% detail comparison...

Nicely done, PhotoMaximum! If the distortion is negligible, I don't know what you'd gain from a newer Extender. If you ever get the chance to borrow a version II or III from a friend, you might try a side-by-side comparison.
I love this thread too! Great collaborative contributions! Thanks folks.

Confirming what you've said with test today.
First shot normal, no shift. Second, shift upward max. Third, shift down max. All shot in Av Mode, center AF point.

I changed the thread title since expanding to sensor comparisons, shift behavior (and God knows what's to follow! ), from the original 1.4X. Hope that doesn't make it harder to find for the readers and contributors.

I won't post the image unless someone really wants to see it: I have the 24mm focal length covered by a bunch of lenses. I used the same setup using an Olympus Zuiko 24/2.8 lens on the 5D mk II. I then compared the file against the 17TSE shot on the 60D. The Zuiko is pretty good. Looking at the rear of the kitchen it is obvious that the depth of field and corners are better with the 17 TSE though.The Zuiko is one of the smallest lenses you will find. I found a perfect condition sample with original metal lens shade for $20 from a guy on Craigslist.
But getting back to the 17 TSE and 1.4x TEs: I am quite pleasantly surprised at how much image quality this combo produces! I like the wide format with the 17 but its great to know that you can use a TE or a crop body SLR and get a really solid 24mm-ish image with this lens...

I regularly use the 1.4 TCII with my 17 TS-E and have always been pleased.
I do a lot of architectural photography and good IQ at the edges is important. IQ at the center,is never an issue and I usually shoot at f8 to f13 so I am not worrying about wide open performance although I note it is very good.
A lot of my work does get printed in double page spreads and the image always holds up well regardless of whether it was the 17 or the 17+TC. The vast majority of my work does end up on the web where any shortcomings that may be detected at 100-200% are invisible.
As for exposure, I never use auto and LV. I use exposure simulation mode and adjust my exposure according to the histogram. I also bracket a lot. I do not recall any significant change in exposure when shifting but there is a significant change in metering.
