I own two Sony a6000 mirrorless cameras (these use Sony's E-mount and have APS-C sensors), one sensitive to visible light only & one that is "Full Spectrum". I also have an interest in Tilt-Shift (T-S) photography. While Lensbaby provides tilting optics (which I have,) they do not provide lenses that can shift, i.e. have the Perspective Control capability. I have already investigated options for purchasing actual PC or T-S lenses ... and yes, I am already aware of the existence of editing programs/modules that can retrospectively correct perspective.

Two such products I found include those for two lines of Canon lenses: https://www.bhphotovideo.com/c/product/1412969-REG/fotodiox_eos_snye_pro_shift_pro_lens_mount_shift.html and https://www.bhphotovideo.com/c/product/1150833-REG/fotodiox_fd_nex_p_shift_pro_lens_mount_shift.html.

For those who have actually had experience working with such Shift Adapters or know of credible reviews that can be cited, I ask you please to reply as to whether these products function as described and what their respective limitations are in practice.

Thank you.

I do not have direct experience with your question - but I DO have great experience ! I have posed this question to myself - especially as it relates to real estate photography. First, I would never use a Canon AF lens for this function - where you can not directly control the diaphram ! - you are asking for trouble.

IMO, you need to be using a manually controlled diaphram lens - I would be using the full frame Irix 15mm f2.4 lens in Pentax K mount ( $4-500). I would be using a simple/cheap adapter like this - https://www.ebay.com/itm/PK-NEX-Tilt-Adapter-for-Pentax-P-K-Lens-to-Sony-E-A5100-A6000-A3000-5T-3-5N-VG10/272585880677?hash=item3f77627465:g:5sIAAOSwax5YxCos:rk:2:pf:0

I see no reason why it would not work - well.

You're right about my potentially having asked for trouble, now that you’ve pointed that out, imagemeister. Frankly, I’m not well-versed in the lenses or mounts of camera manufacturers other than Sony. So this is good reminder. Fortunately, it does not obviate my original question.

Thank you for your suggestion to consider a Pentax lens with a manually-controlled aperture and an adapter for Pentax K-mount to Sony E-mount with either shift or tilt/shift capabilities. I shall consider it.

Well, my question is now moot on three counts:
A. No one else has responded.
B. I can understand why given your answer.
C. In some part thanks to you, I made the decision there wouldn't be much potential savings in the end using this scheme. My decision, admittedly, was sparked by my epiphany a couple of days ago that Sony is releasing their full-frame mirrorless a7 mark ii model in a kit with a 28-70 mm lens and assorted trinkets for $998. That means the a7 ii is effectively selling for ~$600 (as opposed to ~$1800 when it debuted in December 2014.)

Thus, in case anyone has any remaining interest, phase I is about to be completed. Phase II will be purchasing a real T-S lens.

Yes, the tilt shift I describe above will only be effective with a CROP sensor body ! - not FF - there you will need a real T/S or use a medium format lens.
