You deliberately chose such a scene so the dark out-of-IC area blend into the dark sky. In such case yes the 17mm TS-E has the advantage here. You don't need any corner sharpness or filter here. If argued, (just a guess) I might even be able to do a better job with the Schneider 47mm XL (for film) on a 4x5 large format camera if I deliberately shift the lens out of its image circle. Alternatively I could (possibly) try to shift the Sigma 12-24mm lens or the Nikon 13mm f5.6 lens on a Sony A7R camera with custom made parts (Or just IQ250 via ALPA FPS).
Seriously? You're accusing me of deliberately choosing that scene because of the dark sky, because I'm trying to hide the fact that it goes beyond the image circle of the lens, and I'm just trying to win an argument for the sake of it?
You should get some manners before chucking around allegations such as that.
There is NOTHING in that shot that is out of the image circle. In fact, it's cropped ever so slightly on the right hand side of the image due to a light-leak in the H-Cam (I had removed the rail it's supplied with and remounted it, without realizing that you had to cover the screw hole otherwise light would leak in).
Here's another one from a different building. Canon 17 TS-E on the ALPA FPS:
(I only have access to the Instagram version right now. Ignore the borders, that's the full frame of an IQ180.)
edit -
100% corner crop.
You can choose to make whatever assessment you want - objective or subjective - as regards the "quality" of that crop or indeed the entire image. I like it, it's good enough for me, and frankly what anyone else thinks is of little interest.
My choice is to be able to create the image, not walk away because there's no "MFDB" lens that can do it.
/edit
There is no other rectilinear lens/sensor combination on the planet that can get that shot without nodal stitching. None.
I really am quite perplexed as to where your attitude is coming from.
I bought the H-Cam and the 17 TS-E
specifically for that fireworks shot. No other lens on no other format has ever been demonstrated to have sufficient field of view required to get the Burj Khalifa straight on in landscape orientation from that distance.
None.
You want to try the 47 on 4x5? Be my guest. It won't come close. Nor does the 72 on 5x7 (I have it. I tried it).
12mm on FF DSLR? Doesn't have the required field of view, regardless of shifting.
IQ250 with its 1.3 crop sensor, using the Sigma 12-24 (are you serious - that lens is junk on FF DSLR), or the Nikon 13mm? Yeah sure - give it a go and let's see how well you get on.
There are unsubstantiated claims out there that the Nikon 14-24 at 14 will
just cover the IQ250 sensor if you shave the lens hood. That's possibly the only other option that could come close, but it's yet to be proven. IF it can be demonstrated, then I'll buy it in a heartbeat because of the CMOS benefits the IQ250 sensor provides.
Disagreed. See both the test shots I linked, and your test shots as well. The useful image circle of the 24mm TS-E is less than that of the 23HR.
You can disagree all you like. It doesn't make it a fact.
The simple fact of the matter is that the 23HR hard vignettes well before the 24TSE runs out of usable image circle. Ergo, the 24 is capable of taking shots that the 23HR can't deal with. As I very clearly stated - does that mean the 24 is as good as the 23HR if you don't shift? No. It's not. But the simple fact of the matter is that if you only have the 23, then it won't be able to do things that the 24 (and 17) can. Why would you limit your capabilities?
If you must argue, then please read carefully, that my statement used the wording "MFDB lens". The 17mm TS-E is not an MFDB lens but an FF lens, so it does not fall into such category.
No. If YOU must argue, then do so in a civil manner, and base your claims on facts rather than wild speculation that you are incapable of backing up, and tantamount accuse me of cheating with my images.
Both the 17 and 24 are lenses that can be used with considerable degree of success on MFDB. Want to have a semantic argument about what makes a MFDB lens an MFDB lens? Go have one somewhere else, because I won't entertain one.
The usable image circle of both lenses more than covers a FF MFDB back sensor, and they open up opportunities that would otherwise be impossible to shoot.
