The FotodioX WonderPana FreeArc Core Unit for FUJIFILM 8-16mm 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. Hi, anyone tried this lens for astrophotography? I'm curious whether the lens shows any coma (aka comatic aberration; aka distorted stars) wide open?

A: Yes. It's an awesome lens and does show coma in the corners wide open at 1.4. However, once stopped down to 2.8 the coma completely disappears. I've had great success with Milky Way photos and this lens, brilliant colors coming through in the stars - they're not too hot. But ya, definitely don't shoot nightscapes at 1.4 unless you're okay with coma in the corners, play around different apertures or just go straight to 2.8 if you want to be sure there will be no coma.

Q: 8. Does this lens work on Fujifilm Xpro1? Would you recommend this one or Fujifilm 18mm f/2.0?

A: Yes, it does. i bought for my X-Pro1, and then switched t the X-Pro2. it works perfectly on both cameras. It is really an amazing lens and is top quality optic. i prefer it to the 18mm f/2.0 for several reasons:a 24mm equivalent is a better lens for landscapeIt is one full stop faster than the 18mm, so better in low light conditions and it allows you to create amazing bokehIt is weather resistantHope it helps
