This WonderPana FreeArc Core Unit from FotodioX is designed to specifically fit the Canon TS-E 17mm f/4L lens, as well as a separately available WonderPana 6.6" Holder Bracket. Those items can be combined to 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. A compatible 145mm inner-pinch lens cap for 145mm FotodioX round filters is also provided.

The included WonderPana FreeArc Core Unit consists of a bayonet front filter ring. Use of the WonderPana 6.6" Holder Bracket is easily accomplished by separately attaching its two assembly pieces to opposite sides of this WonderPana Core Unit using the six included brass short screws. Pretapped threaded inserts along the edge of this Core Unit accommodate those screws and ensure correct positioning of the two assembly pieces so that they are placed parallel to each other and can hold a 6.6" wide filter between them. The combined WonderPana Core Unit and WonderPana 6.6" Holder Bracket can then be attached to a Canon TS-E 17mm f/4L lens.

After being fitted onto a Canon TS-E 17mm f/4L lens, the bearing design of this WonderPana FreeArc Core Unit 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.

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. Pretapped 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 is 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.

This FotodioX WonderPana FreeArc Core Unit includes front filter threads, which allow a FotodioX 145mm round filter to be used along with a WonderPana 6.6" Holder Bracket. If a 145m round filter is used on the attached WonderPana FreeArc Core Unit, the rectangular filter slot closest to the rear of the holder bracket becomes unavailable.

The FotodioX 145mm Center-Pinch Snap-On Lens Cap for Select WonderPana Systems and Filters is a 145mm front lens cap with a squeeze, spring, and snap-on mechanism. It is easy to install as well as remove and can attach to a WonderPana FreeArc filter holder system in order to protect the front element of a lens that any one of those systems is mounted on. Additionally, with the exception of the FotodioX Ultra Slim filters, this lens cap can be used to protect a FotodioX 145mm filter that is mounted on a FotodioX WonderPana FreeArc filter holder system.

Lens caps protect your lens or filter from scratches, fingerprints, and the elements when the lens or filter is not in use.

Q: 1. Can this be adapted to work on a full-frame Sony camera such as the A1 or an A7r IV ?

Q: 2. Does this Filter Holder work with Rokinon DSX 14mm EF-Mount cinema lens?

A: No, the FotodioX WonderPana 145 Core Unit Kit for Rokinon/Samyang AF 14mm f/2.8 RF/FE does not fit onto the Rokinon DSX 14mm EF-Mount cinema lens.

Q: 3. 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: 4. 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: 5. 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: 6. 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: 7. 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: 8. 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: 9. 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: 10. One of the reviewers mentioned the Fotodiox Wonderpana Freearc system to protect the front lens of the TS-E 17mm. I like that idea, but which one?

A: I have used the TS-E 17 for a couple of years. Absolutely love this lens. I however don't want to put anything between my great UD L series glass and the subject. I will admit that I was concerned about the protruding front element at first. However the concerns have faded with use. I usually have the lens cap in place unless I'm taking a shot, but have trekked about in major cities like Chicago and D.C. with the lens ready to go. I do recommend that you cary a good cleaning kit in your bag, and as with all optics keep 'em clean. This lens is absolutely awesome - go shoot and get comfortable with working with such an outstanding piece of glass!
