I researched the lens hood mask using black insulation tape placed across the Fuji hood and tested for vignetting at minimum focus and infinity focus at f/2.4 and f/22. It was quite easy to see the effect and any differences each time I moved the insulation tape further out from axis. Eventually I settled on a position that gave no noticeable vignetting at any setting and I measured the hole size. The 60mm lens hood mask is a 77mm push on Kaiser 6977 lens cap with a 54mm x 36mm hole cut in with a scalpel. Obviously I used a metal safety straight edge during the cutting process. I packed out the core of the lens cap with card and I built up the outside with card too to make a level and firm cutting surface. Since I took this picture I have chamfered the outer edge of the lens cap aperture with a scalpel and a fine file to create a crisp sloping edge. This avoids having a shiny reflecting surface close to the lens axis. I noticed a bit of flare kick back off the mask aperture today when shooting a challenging contre Jour shot. It’s tweaks like these that make all the difference between an okay shot and a perfect shot. Making the mask was easy, it’s very effective and can be used on demand or become permanently glued in place once tested.
Step up ring
I bought a cheap ebay 39mm uv filter pitched as a protector for the 60mm Fuji lens on Ebay. It cost me £6 including postage. I removed the retaining ring and the glass and kept the outer ring to use as a spacer. I then used Locktite to bond a Kood 39mm to 52mm step up ring onto my spacer. When attached to the lens there is a 3mm clearance between the step ring and the front bezel of the lens. The lens hood easily fits over this step ring assembly. I can now use my 52mm ND and Polarising filters on all my Fuji lenses. At today’s workshop I used a 4 stop ND on this lens to change a flash exposure from ISO 200, 1/160th, at f/11 to the same at f/2.8. It was the perfect result for the picture.
Please feel free to add your experiences with this lens.
