Weather sealing in Lenses and Cameras, a new trend !
Weather Sealing is not a necessity for the Outdoor photographer but it’s certainly a desirable option when choosing a new camera or lens. When i was shooting with film cameras my Pentax gear was not sealed and there wasn’t many of them that were sealed at that time. I was using plastic bags when it was raining, not the best thing but it gets the job done, i’m still using plastic bags and/or raincover for my gear with no weather sealing.
Camera and lens makers are including Sealing into more of their products now and it’s a good thing for the Outdoor photographers (Wildlife, Landscape , sports …..). Even Fuji with their new X-T1 and some WR lenses coming later this year is joining the party. Unfortunately not all manufacturers indicates clearly which lenses are sealed and to which degree they are. Canon L series of lenses are not all sealed, some not at all, some partially (they require a filter with a gasket to complete the sealing) and some are fully weather sealed. Nikon is also vague on this point, i’m not too familiar with their lenses and which ones are sealed.
Olympus and Pentax have a very good reputation for working in bad weather. I’ve been shooting with some Pentax WR and DA* lenses for some years now and i can attest that they can be used in any bad weather that we have here in Canada.
Pentax is clear on which lenses are weather sealed and to which level:
Recently i bought a Tamron 90mm Macro VC for my Canon kit and it is equipped with a rubber gasket around the lens mount but no other seal in the lens. I don’t know if the Tamron seal will be as good as the Pentax or if it will still work well after some years in the field, but it’s good to see a third party lens makers adding this feature to their lenses.
I did a short Video to show the difference between the Pentax and Tamron gasket around the lens mount:
The camera is also important, not all cameras have the same degree of protection against rain and dust. The Card and battery doors of my Canon 7D doesn’t have any gasket even if the camera is said to be weather sealed, however there are seals in other parts of the camera, compared to my Pentax K20D which have the best doors i have used with rubber gaskets and a very good locking mechanism.
All in all weather sealing is now part of the choices you have to make when choosing a new camera, lens or system, when i have choices i will buy a sealed lens over another one if all things are similar. It’s not a necessity but it certainly makes your life easier in the field and gives you a worry free experience while concentrating on getting the best shots you can.
