The FotodioX WonderPana FreeArc Core Unit for Canon TS-E 17mm Lensis a two-piece assembly designed to be used in combination with a FotodioX WonderPana FreeArc Core Unit, a WonderPana 145 Core Unit, or a WonderPana FreeArc Aluminum Step-Up Ring. A WonderPana Core Unit or a WonderPana FreeArc Aluminum Step-Up Ring with the WonderPana 6.6" Holder Bracket attached can then allow for the convenient use of two 2.5 to 4.0mm-thick filters measuring 6.6" wide, or one 2.5 to 4.0mm-thick filter measuring 6.6" wide along with one FotodioX 145mm round filter behind it.

Use of this holder bracket is easily accomplished by separately attaching its two assembly pieces to opposite sides of a WonderPana Core Unit or a WonderPana FreeArc Aluminum Step-Up Ring using the six included brass short-screws. Pre-tapped threaded inserts along the edge of a WonderPana Core Unit or FreeArc Aluminum Step-Up Ring accommodate those screws and ensure correct positioning of the two assembly pieces so that they are positioned parallel to each other and can hold a 6.6"-wide filter between them. The combined WonderPana Core Unit, or WonderPana FreeArc Aluminum Step-Up Ring, and WonderPana 6.6" Holder Bracket can then be attached to a compatible lens.

For WonderPana Core Units that consist of a rear lens collar and a front filter holder, pre-tapped threaded inserts along the edge of the front filter holder accommodate the six brass short-screws for correct positioning of the WonderPana 6.6" Holder Bracket's two assembly pieces. Once the holder bracket and a front filter holder are combined, and the separate collar has been slid over the rear of a compatible lens until it has achieved a secure fit, the front filter holder with the attached holder bracket can be screwed onto the front of the installed rear lens collar.

After being fitted onto a compatible lens, the bearing design of the WonderPana FreeArc Core Units and WonderPana FreeArc Aluminum Step-Up Rings allows a WonderPana 6.6" Holder Bracket to be rotated 360°. This permits the use of graduated neutral density and other filters that are enhanced by varied positioning. While a WonderPana 145 Core Unit does not include a 360° rotating mechanism, eight pre-tapped threaded inserts all around its edge allows the WonderPana 6.6" Holder Bracket to be installed in 45° increments so that rectangular filters placed within it can be angled to the best approximate position relative to the subject in front of the camera.

The FotodioX WonderPana 6.6" Holder Bracket provides two pairs of filter slots, a configuration that accommodates two compatible rectangular filters. For each rectangular filter that is placed within one of the holder bracket's slots, its position can be secured using the included brass long-screws. Pre-tapped threaded inserts along the outside of the holder bracket allow the long-screws to each apply pressure to a spring-loaded retainer within each filter slot. When a pair of the long-screws are used, the level of grip upon a rectangular filter can be varied, which can complement the use of graduated filters whose effect can be adjusted to better suit changing lighting conditions or creative demands by sliding them up or down within a filter slot.

Each FotodioX WonderPana Core Unit or WonderPana FreeArc Aluminum Step-Up Ring includes front filter threads, which allow a FotodioX 145mm round filter to be used along with this filter holder. If a 145mm round filter is used on the attached WonderPana Core Unit or WonderPana FreeArc Aluminum Step-Up Ring, the rectangular filter slot closest to the rear of the holder bracket becomes unavailable. The WonderPana 6.6" Holder Bracket features a lightweight, aluminum-alloy construction that has a corrosion-resistant, black anodized finish for durability. A rigid pouch is included for storage and transport.

Related Questions and Answers

Q: 1. I was wondering if anyone has any experience using this this lens with the Canon Extension Tube EF 12 II. Does it affect tilt/shift function? Basically, I am looking for some macro functionality with tilt/shift. Thanks.

A: You can use the 45mm Tilt and Shift lens with the extension tubes but you will lose some tilt and shift functionality.

Q: 2. Which Canon extension tube is compatible with this lens?

A: According to Canon, both tubes will work with the 90mm TSE. You will of course have a limited focus distance. The lens manual lists the working distance for both tubes. You can view the manual here; https://www.bhphotovideo.com/lit_files/524712.pdf

Q: 3. Hi!! Do you know tell me if the 17mm TS from one side of the shift all the way to the other is equivalent image circle to a 10mm lens (full frame)? I mean, if i shift up, take a picture, than shift dow and take another, then put them together i can gat the same angle of reach of a 10mm wide angle lenses? How many mm wide the hole possible Tilt circle is equivalent? Thanks a lot!! Cheers!!

A: Yes you can shift - take a center shot horizontal - a full left shift and a full right shift and merge all three images in photoshop. The view would be about equal to a 10mm lens in the left and right view. Matching exposure and color can be a bit tricky depending on the image. Also the extreme outside of the final image will be a bit soft - you are reaching the extreme edge of the circle.

Q: 4. does Canon 17mm ts-e lens vignette?

A: I have been using the 17 ts-e for about a year and I have yet to have a problem with vignette with using the lens as is. I have shot mostly commercial buildings... interior and exterior in bright and low lighting conditions and this lens has been excellent. I have this mounted on a full frame Canon 5D II The only time I have experienced any vignetting was when adding the Lee filter system and it was made clear by Lee that I would have a bit of edge vignette with this setup. Good luck and you will love this lens!

Q: 5. Any results with the Canon R5. I've heard that this lens while optimal on Canon mirrored cameras is soft on Canon RF mount cameras?

A: We have had no reports about any issues using this lens with a lens adapter on Canon RF cameras.

Q: 6. Does this lens come with an instruction manual or just a one page generic instruction sheet that covers all Canon lenses? ( my came with the one page generic sheet)

A: The lens does not come with an instruction manual. Most manufacturers are only putting manuals onto their website to download instead of printing and shipping them with products.

Q: 7. Is this lens compatible with either the Canon Rebel XSi and/or Canon EOS 5D Mark III cameras? Thanks!

A: Yes, this lens is fully compatible with the Canon XSi and 5D Mk III cameras, and any other Canon EOS Digital or Film SLR cameras.

Q: 8. Is there anyone out there who has used it on the new Sony Ar7II with the metabones adapter? What is your experience? Sharpness, auto anything work?

A: You could use this with the A7R II using an adapter like those from Metabones.

Q: 9. Lens hood included or is this lens to be used with the glass exposed like that?

A: The lens has no hood or filter ring. You must use it with Lee or other filter holders. The lens is strictly manual focus, manual exposure and is best used with a 1 deg. spot meter. You can rotate the tilt and the shift so both can be used in different orientations. Somewhat like the front of a view camera.

Q: 10. Do these (17mm TS) come with an instruction manual or just a generic instruction sheet that covers all canon lenses( that's what mine came with)?

A: The best information I have found has been on YouTube. Do a search for tilt shift lens and go from there.
