The FotodioX WonderPana 6.6" Holder Bracket is 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. Will this work on Canon R-mount cameras with the EF adapter?

A: Absolutely! The TS-E 17mm f/4L will work wonderfully with the EF-RF adapter.

Q: 2. For Portrait vs Landscape photos, do I need to use the Rotation function to 90 degrees (+- depending on left/right camera rotation)?

A: No, one does not adjust the mount rotation: +/- 90° on the Canon TS-E 17mm f/4L Tilt-Shift Lens based on shooting orientation. Rotation of the tilt-shift mechanism should be done based on what is needed for the specific composition. This is independent of camera orientation.

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 this lens somehow let the user know if the photo is in focus? Is there something that blinks? I am shooting with a 5D Mark IV. Thanks!

A: Hi Austin. This is a manual focusing lens. The blink will occur with auto focusing lenses. This lens is intended to be used with a tripod and stopped down a bit (f/8.0) should work. Use the manual focus ring to set the distance. With the aperture stopped down on a 17mm lens just about everything in the frame should be in focus.

Q: 5. 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: 6. Lens hood included or is this lens to be used with the glass exposed like that?

A: Canon doesn't make a hood for this lens. WonderPana Filter Holder for Canon 17mm TS-E can be used as a hood.

Q: 7. Can this be adapted to work on a full-frame Sony camera such as the A1 or an A7r IV ?

A: Yes, you are able to use the Canon TS-E 17mm f/4 tilt-shift lens with an adapter on the Sony A1 and A7RIV cameras.

Q: 8. is the 17mm canon lens compatible with a Nikon d600 full frame body? thanks

A: The Canon TS-E 17mm f/4L Tilt-Shift Lens is not compatible with Nikon cameras, so you would not be able to use it on the D600.

Q: 9. 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: 10. 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!
