Reviews of existing systems and dIY solutions<\/h3>\n

The second part on rain covers, introducing the problems with fabric camera covers and presenting two DIY cover ideas.<\/p>\n

As always, a full list of the articles in this blog can be found HERE<\/a>.<\/em><\/p>\n\n

Problem with previous raincover<\/h4>\n

<\/div>\n

I presented in the first article<\/a> of this series a raincover with weatherproof fabric. Despite correct performances during short rain showers of weak intensity, I had expressed reservations on the effectiveness in adverse conditions by the lack of waterproof seams (either by welding or adhesive tape). I was right as this summer, during very short but intense storms, the water pressure soaked the fabric and allowed water to seep into the joints, after being exposed only about ten minutes.<\/p>\n

The fabric raincover I used before. Note the many seams that are not sealed and will allow water to infiltrate by capillarity. Without information on the fabric\u2019s resistance to water pressure (water column), it is difficult to know its limits.<\/em><\/figcaption><\/figure>\n

<\/div>\n

It would be possible to solve this problem with sealants for tents applied by brush, but the construction of the cover does not make the application easy and contains several unreachable areas (seams reinforced by grosgrain ribbon).<\/p>\n

I fell back on emergency solutions that I had bought just in case, simple plastic films like those from the Op-tech brand. They have the advantage of being very inexpensive, being easily foldable and being easily stored into any pocket, so you can always have one on you.<\/p>\n

They consist of a plastic film tube, with a cord at the end to tighten it around the lens hood. Unlike an impregnated fabric which only resists a certain pressure (water column), the plastic film will be completely waterproof as long as it is not pierced. Its transparency also makes it easy to see the camera and lens controls.<\/p>\n

However, these protections are not optimal. First of all, an opening is provided to pass the eyecup of the device, but I do not believe that the ones of the a7r2 or a7s2 are water resistant. Without a seal, this window is also a possible entry point for water which will then run off onto the rest of the camera. The cover has also been designed for use with autofocus lenses controlled by the housing. As soon as a good size manual optic is mounted on the camera, it becomes very difficult to pass a hand under the lens to reach the focusing or iris rings.<\/p>\n

So I chose to create a solution for myself by again using translucent shower curtain pieces tailored to the following needs:<\/p>\n
