This FotodioX WonderPana FreeArc Core Unit Zeiss 15mm Lensfrom FotodioX WonderPana FreeArc Core Unit Zeiss 15mm Lensis designed to specifically fit the Zeiss Distagon T* 15mm f/2.8 (ZE and ZF.2) 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 two components, a front filter holder and a rear lens collar. Placement of this FreeArc Core Unit onto a Zeiss Distagon T* 15mm f/2.8 (ZE and ZF.2) lens is easily accomplished by sliding the rear lens collar over the rear of the lens until it has achieved a secure fit. Afterward, the front filter holder can be screwed onto the front of the installed rear lens collar.

To use the WonderPana 6.6" Holder Bracket with the FreeArc Core Unit for a Zeiss Distagon T* 15mm f/2.8 (ZE and ZF.2) lens, pretapped threaded inserts along the edge of the front filter holder accommodate the six included brass short screws for correct positioning of the WonderPana 6.6" Holder Bracket's two assembly pieces so that they are placed parallel to each other and can hold a 6.6" wide filter between them. Once the holder bracket and the front filter holder are combined and the separate collar has been slid over the rear of a Zeiss Distagon T* 15mm f/2.8 (ZE and ZF.2) lens, the front filter holder with the attached holder bracket can be screwed onto the installed rear lens collar.

After being fitted onto a Zeiss Distagon T* 15mm f/2.8 (ZE and ZF.2) 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.

Related Questions and Answers

Q: 1. Does the lens come with the filter ? It is not stated in the included items

A: Yes, the ZEISS Distagon T* 2.8/15 ZM lens ships with the center weighted filter included.

Q: 2. why does this lens need a Center Filter?

A: The center filter is meant to average the light distribution from the center of the lens to the frame edges to minimize vignetting - especially in areas of even density, such as blue sky, seamless backgrounds etc. The use of the center filter was more important in the pre-digital days, when post correction was more difficult.

Q: 3. Is the lens hood removable to allow graduated ND filters to be used without a space between the filter and the lens on the Zeiss 15mm Milvus?

A: The lens shade on the ZEISS Milvus 2.8/15 is removable, allowing use of gradated filters in front of the lens element.

Q: 4. What's the weight (not the package weight)?

A: The Bright Tangerine Morrissey 15mm LWS Lens Support Core (BH # BRB30101003) weighs in at about 4 oz.

Q: 5. Can the Zeiss Viewfinder ZI for Zeiss Ikon Camera When Used with 15mm ZM Lens be used with a Leica M-P (240) rangefinder camera?

A: Wrote to Zeiss about this 15mm viewfinder on a Leica M. Here is what they said: With the Zeiss Ikon rangefinder camera, as well as with the analogue and digital Leica M-mount rangefinder cameras, the hot shoe on top is always slightly off-centered (shifted to the right). This small amount of off-centering does not influence the horizontal parallax view with any attached super wide external viewfinder (e.g. our 15mm viewfinder). The amount of off-centering is so small relative to the horizontal field of view that it plays no role at all in practical use. So the viewfinder framelines in the 15mm only show the parallax markings for the small vertical shift between infinity and 0.7m closest focusing distance. So this viewfinder can be used on all M-mount cameras together with any 15mm lens without any problems."

Q: 6. Can this filter holder work with the Rokinon DSX 14mm cinema lens ?

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

Q: 7. Does this lens couple with Leica Rangefinder?

Q: 9. Can I use a 77mn variable nd filter with this adaptor? I have tokina 16-18 mm

A: FotodioX WonderPana 145 Core Unit Kit for Tokina 16-28mm Lens is very wide. It accepts 145mm filters. Unfortunately 77mm filters won't work as they are too small.

Q: 10. Could you please test the vignetting of this lens (and 18mm as well) on Canon FF bodies with LEE SW150MKII screw-in adapter ring and filter holder attached?Basing on my experience with Canon EF 11-24 f/4 lens with the dedicated LEE SW150MKII system adapter for this lens and filter holder the minimum usable focal length was about 14 mm. I would like to go as wide as possible but without vignetting.

A: This filter system has not been checked by ZEISS for use on the Milvus 15 lens. You can refer to the compatibility chart on their website at: a href= http://www.leefilters.com/index.php/camera/system-match target= _blank http://www.leefilters.com/index.php/camera/system-match/a
