The FotodioX WonderPana 145 Core Unit Tokina 10-17mm Lens UV Filteris a general use, clear filter that is compatible with the FotodioX WonderPana 145, FreeArc, and Absolute filter holder systems. It is designed to absorb ultraviolet light and reduce the bluish cast of daylight. Aside from the reduction of unwanted blue casts, no additional coloration or contrast is created, and adjustments to exposure are not required while using this filter.

This filter is constructed from optical glass for clarity as well as color fidelity and features a lightweight, aluminum-alloy filter ring. The filter ring includes a brass side knob that provides increased leverage when mounting or unmounting the FotodioX 145mm UV Filter.

This UV filter is also useful as a general protective filter to leave over lenses at all times. Such filters help to reduce dust and moisture from reaching your front lens element and provide additional protection in case of drops or situations where scratching could occur.

Q: 1. will this product work with both the underwater housing and the skeleton housing for the Hero3?

A: No the lens hood is not removable

Q: 3. Has anyone actually tried this with an FX camera, like a D750? What I've read says that you get normal fisheye effect--without vignetting or circular image--at the 17 mm range. Or does this lens make the camera switch automatically to DX crop factor?

A: As far as I know, the D750 format needs to be changed manually from FX to DX.

Q: 5. Does this lens provide a circular fisheye on a full-frame sensor?

A: The Tokina 10-17mm f/3.5-4.5 AT-X 107 AF DX Fisheye Lens for Canon would not give a circular fisheye on a full frame. At 10mm the lens hood is visible in the image when used on a full frame camera. Once zoomed to 15mm the hood is no longer visible.

Q: 6. is this lens compaitble with my black magic 6k? If so, how much crop can I expect?

A: This is an EF-mount APS-C/Super35mm format lens. Used on your BMPCC6k and depending on the resolution you use, you would have a minimum of 1.558x crop factor (using 6K full sensor readout), meaning this would be a 15.58mm-26.49mm equivalent lens.

Q: 7. With these lens', is it possible to remove the lens itself and replace it with another? For example, take out the UV/CPL/ND8 lens and replace it with a 53mm underwater lens? Rather than buying a completely new WonderPana Underwater kit?

A: The filters contained in the B&H # FOWP145UWK Underwater filter kit are compatible with the kit B&H # FOWP145GOK. They are the same 53mm thread size.

Q: 10. Im beginning to shoot indoor real estate work and Im looking at this as well as the Tokina 11-20mm F2.8. How do the two compare in image and build quality?

A: The 11-20 would probably be better for indoor real estate shooting, as it is rectilinear, while the 10-17 is an actual fisheye lens.
