Matte Boxes (which relates to being bar mounted) and Sunshades (which relates to being mounted directly to the lens) are a vital tool not only to aid the use of filters, but also to stop unwanted flares and light spill onto your lens. Matte boxes and Sunshades are designed and manufactured with different ergonomic factors and considerations which require the user to fully understand so that the right tool is used or purchased in respect of your filtration techniques for use in the field. To this end our information pages have tables which will advise you of the different filter sizes, mounting options and other various points to consider for currently produced products by our listed manufacturers No one Matte box or Sunshade can cover all aspects of what one may require now or in the future, but by deduction and consideration one should be able to whittle down the finer points that will be relevant to one’s self, and so to this end I hope our pages help you.
