ef-s lens weatherproof?

Hi

I've been considering upgrading from a 40D to a 7D. A big draw is the weather sealing on a crop body but I don't think there are any ef-s lenses that are similarly sealed. I know L lenses are an option but that doesn't help much at the widest end.

Do you think they'll make an L type for ef-s, maybe a blue L (trademark) ;) or does the lack of any show Canons real commitment to this mount?
 
ef-s is a cost saving measure (as is any Nikon DX lens or Sigma DG etc etc) because it means they can concentrate on making glass thats only got to come up to scratch in the area seen by a APS-C sized sensor and not for a full 35mm one. I don't think "cost saving" is something customers for Canon's flagship lens range will be reassured by.

Thats not knocking EF-S or DX/DG lenses, but you just have to be aware why they exist...

You are right though, you need a weathersealed body to go with the weather sealed gasket on the L lenses. I don't think all L's have the gasket though... I could be wrong mind you!
 
Yep, not all L's are weathersealed. I should have said 'some L's'

I didn't know that about ef-s being a cost saver. I thought it was about moving the glass closer to the sensor enabling the sensor to be smaller (suppose this is the saving bit :lol:)

But still, why have a weathersealed ef-s camera with no equivalent lens.
 
But you don't have a EF-S camera... you have a APS-C sized sensor in your Canon EOS body... the mount takes EF and EF-S lenses... if you want the pro spec lens features, just get the pro-spec lenses... which are all EF mount.

Point taken, it's getting hammered home :bonk:

I'll just have to use my ef-s 10-22 when I can keep it dry maybe save a little more for a 24-105L.
 
Don't worry too much about it, its got to be seriously wet before you'll see anything happen - even then it will be good old error 99's as your first indicatator that its time to give up :d
 
Bit of electrical tape around the mount point if you are worried?
I bought a couple of optech rain covers, ~£5 for 2.
Plastic bags, with a pull tie incorporated for the end of the lens

I disagree slightly, the first thing I had a problem with on my 300 f/4 was the AF, it became intermittent at best and took the best part of a week to dry out properly before it started working fully again.:(
 
I had a google, and only half of Canon's L lenses are weathersealed.

Out of a total range of around 70 different lenses, over 30 are L, but only half of those are weathersealed.

Lenses marked * are rumored to have some level of weather protection but this is not endorsed by Canon. Easiest way to tell is the rubber seal around the lens mount.

EF 16-35mm/2.8L USM
EF 16-35mm/2.8L II USM
EF 17-40mm/4L USM
EF 24-70mm/2.8L USM
EF 24-105mm/4L IS USM*
EF 70-200mm/4L IS USM
EF 70-200mm/2.8L IS USM
EF 28-300mm/3.5-5.6L IS USM*
EF 50mm 1.2L USM*
EF 85mm 1.2L II USM*
EF 200mm f/2L IS USM
EF 300mm/2.8L IS USM
EF 400mm/2.8L IS USM
EF 400mm/4DO IS USM
EF 500mm/4L IS USM
EF 600mm/4L IS USM
EF 800mm/5.6L IS USM
MkII Extenders 1.4x and 2x

Alternatively, fit one of these http://www.warehouseexpress.com/buy-optech-rainsleeve-flash-pack-of-2-/p1029380 :D
 
Only the 300 f/2.8 IS, ouch! (No weather sealing on the f/4 IS :()

I'm very tempted by the 7D, so the lenses I'd have to get would have to be:

70-200 f/4 IS
300 f/2.8 IS

That'll weigh me down a little! :p

There seems to be a major shortage of shorter primes in there, although I guess thats partly due to them not being replaced as much and them usually not being L lenses (85 f/1.8 for example).
 
From spending 3hrs in heavy snow earlier in the year, I can conclusively state that the 10-22 isn't weather sealed :D

Despite heavy fogging once indoors, it continued to work throughout and after a day in the airing cupboard has been fine since (yay for the purity of snow :lol:).

I don't think we'll ever see weather sealed ef-s lenses as Canon would rather we upgraded to L glass and appropriate full frame bodies...

Maybe the 70-300 IS I have which took a lot of "abuse" was of a more solid construction then than a L lens ;-)
 
I guess that the reason shorter lenses are not weather sealed, is because you are less likely to patiently wait for a subject (such as wildlife) with a short focal length - longer primes and zooms are you typical "stake-out" lenses. You don't need weather sealing if you are in a studio doing portrait (although it could be stated that landscape lenses could benefit).

EF-S lenses are built to a budged, and as Hoppy has pointed out, only the L series lenses have this feature, which carry a (much) higher premium.

Or that a variety of things can go wrong with the lens due to wetness.:p

The lens was perfectly fine, worked fine, but you had to use manual focus a lot of the time (which meant a lot of my shots were soft...:(:bonk:)
