p.1 #1 · p.1 #1 · Weather sealed lenses...does a list exist?

Is there a complete list of the weather-sealed Canon lenses to be found anywhere? I've looked and can't seem to locate anything worth a dang.

sorry if this has been covered here but my search is coming up blank.

why didnt Canon just put a serviceable rubber seal on the 1 series bodies to begin with...so all lenses would be weatherized.
still like to know why the 70-200 f4 NON-IS doesnt have the gasket

This is because the sealing around the mount is not the entire extent of the sealing required for the lens. The lens itself has to be sealed inside the focusing and zoom rings (where applicable), as well as any switches and other seams. The front of the lens in many instances also needs to be sealed with a filter.

According to TDP, there is partial sealing because the lens has dust- and moisture-resistant gaskets inside the barrel for the switches and rings. But the rear of the lens lacks a gasket.

I only included these because they have been announced for release in the future, and as such, their weather sealing specifications are known.

You could add 70-200/2.8L IS to the list. It's not current production, but it's in widespread circulation.

But dust gets inside the 100-400L.

Weather sealing does not mean "impervious to dust ingress."

Any lens that experiences a significant change in internal barrel volume as a result of focusing or zooming is prone to collecting dust, because that air has to come from somewhere. It is unavoidable. Weather sealing reduces the amount of dust that can enter, but doesn't eliminate it.

The fact that the 100-400L uses a push-pull zoom design with a very long extension increases its tendency to collect dust.

For a lens like the 24-105L, if dust sticks on the extended portion of the barrel when you zoom, any chance the dust can get inside when you retract the lens?

Thanks.

Yes, it's possible. There is a gasket that seals off the gap, but it is not 100% dust-proof. It's mostly effective, but things can and do get past it eventually. For example, moisture and sand can make their way past the seal.

There are two other major points of entry for this lens. One is the area behind the plastic ring around the front element, which hides some screws. Another is the rear element, because it is not fixed. Even though the mount has a gasket, dust that is already in the mirror box can enter the lens during use. I believe there is some additional sealing for this moving rear element, but it may not be enough.

In any case, all consumer camera lenses eventually get dust in them, even those that are completely internally focusing. Some are more prone to it than others, but it's only a matter of time. The impact on image quality is negligible, and if you are really annoyed by it, you can simply have the lens disassembled and cleaned periodically.

Most L lens that have weather sealing, have very small felt type material on the barrel canal, which as you mentioned is the portion of the barrel were it zooms. This is very similar to a DVD/CD player in your car which helps reduce any dust from entering on the inside. This is why I feel it's important to clean the barrel as often as you can especially if your shooting in dusty conditions since this area can easily built up with dust and eventually enter inside the lens.

Wickerprints, I'm curious what your analysis of the Contax-Zeiss 35-70's weathersealing is. If you've never seen one don't worry, but I'm curious nonetheless.

I have no idea. I'm not at all familiar with this lens.

About the only thing I can tell you is it appears to be an older design. For the most part, older lenses didn't bother with weather sealing. Manual focus, all-metal barrel construction with small tolerances make such lenses somewhat more intrinsically resistant to dust ingress, but again, if there's a change in air volume, the lens *will* suck in dust over time. How much and how rapidly depends on numerous factors.

Think of it this way. Have you ever heard of a camera lens that was 100% impervious to developing fungus or condensation? Of course not. Well, if fungal spores can find their way inside the lens (granted, these things are in the air during assembly as well, but it doesn't explain the moisture needed for germination), then where did it come from? No lens you can buy is truly hermetically sealed. Even hard drives are not hermetically sealed.
