It occurred to me, that due to the limited availability of the Cyclopital3D Auxiliary-
these adaptors, it seemed a fair challenge to produce an attachment that would simply mount interchangeable lenses to the W3 at very low cost.
I have included a downloadable template that will help anyone wishing to build an attachment for the
W3 and possibly the W1! The construction materials are not critical, but I already had an assortment
of MDF which served the purpose; 3 mm and 6 mm samples being my choice. PVA adhesive was
used where needed. The two lens mount apertures are 30mm diameter, which I shall explain later
and the fixing hole is 5mm diameter, permitting a self tapping fit of a camera securing screw.
The completed attachment was finished with black household enamel spray.
Please note that I have not included any apertures for the W3’s flash and microphones as this would
Choosing lenses is not straightforward; ‘Try before you buy’ not being a readily available option.
I have tried various wide-
noting. It seemed to me that the diameter of the front element of the lens needs to be as large as possible to avoid a vignette at the corners of the image; If this vignette is cropped out, the
perceived advantage of the lens is lost to some extent.
So, with this criteria in mind, I set out to purchase yet another pair of wide-
use eBay for my search, with an open mind regarding the lens manufacturer etc. My search criteria directed me to a page listing a “74-
The description of the lens quotes the mount diameter as ‘37’ (37mm), matching that of the
Cyclopital3D adapter. The overall diameter of the lens is quoted as ‘74’ (74mm) which is accommodated by the 75mm interocular separation of the Fuji W3. With such a large diameter
front element, this lens provides an extremely wide viewing angle. In practice, the field of the W3
set at the wide end of the zoom, is increased by around 40% without any sign of vignetting.
The Andoer lens is built with lens elements, removal of the front element leaves the macro section available for really close-
used to capture macro images. A further feature is the inclusion of a separate 30 mm to 37 mm
