Pre-ordered canon 7D

Postby very_confused09 » Thu Sep 03, 2009 6:04 pm

Hi I Pre-Ordered the Canon 7D & the 28-135 a couple of days back. Because of the large number of orders, I am worried that I may not get it (what is the chance?). I pre-ordered from Amazon.

If it does get shipped, I have a few questions:

(1) weather sealing. It snows very badly here and I want to ensure that my experience is not spoiled. Are any add-ons available that can improve the sealing?

(2) lenses, since the lens I will have would be a 28-135 and I want to cover the whole 18-300 range, what lenses would you recommend?

(3) would SD cards work (or my old ones go to trash)? which CF card would you recommend?

1) http://www.cameraarmor.com/ ??
2) sell the lens, get the new 15-85mm and 70-300mm IS USM
or if you want better low light zoom, get 17-55mm f/2.8 IS USM.
3) it will not work, but if you shoot at full resolution (18mp) you might want high capacity card, at least 4GB / card. (sorry previously said sd card will work) :D

The body already has a fair degree of sealing. As it is new, it might take some time for 3rd party add ons to come out and improve it further. Do note the lens needs to be sealed also to complete the package, which does limit the choices a bit to the higher end lenses.

The only two wide sealed lenses are the 16-35L and 17-40L. The only sealed lens I'm aware of that goes to 300mm is the 28-300L. Not cheap. One of the 70-200 lenses with an extender may be an alternative, but I'm not sure if the extenders are sealed. If you're willing to lose the sealing, of course that opens up the possibilities significantly. Perhaps wait to see how the new 15-85 performs for the wider end, and the 70-300 for the longer end.

I don't think it takes SD cards at all. While you can get adapters, I found performance to be horrible. Best go straight to CF. I've found the Sandisk range to be great. I'd suggest going for at least an Extreme III, but the IV does give a noticeable improvement particularly if you shoot continuous a lot.

make sure you get a camera armour body cover. That will protect your 7D.

1) Body armor. Unlike the E-3, Nikon D3 series, Canon 1D series, and Pentax cameras, the 7D is not fully weather sealed (like the D300/D700). It only has some resistance that make it withstand some forms of weather for a short amount of time.

Another thing that works is the synthetic rubber spray you can buy at Walmart. Very cheap. Simply dip a cotton swab into it and rub where u think needs more sealing. This makes your camera ugly, but I would rather have an ugly camera than a non working one, agree?

2) Depends on your budget. The 7D will demand a ton out of your lenses, considering that it's much more dense than 40MP FF and the largest MP on FF is only 24 still. Maybe a lower MP camera like the 50D or 40D would be better unless your budget is unlimited. In that case, the new Tamron 17-50mm VC or 17-55mm f/2.8 IS USM Canon will work great, coupled with a Sigma/Tokina 50-135mm or Sigma/Canon 70-200mm f/2.8. Adding a TC to the 70-200mm gives you about 100-300mm f/4.

3) No there is no way you can use your SD cards. Even if you could, they would most likely be too slow to even be using on an 8FPS , 18MP camera. Large picture size and a ton of em if you shoot sports or fast action (the latter everyone will eventually shoot).

Hope that helps!

how about you cancel that useless 28-135mm kit and get a proper one instead (15-85mm, 18-135mm or body only + 17-55mm jumps to mind)?

and get Extreme III Sandisk CF cards or even Extreme IV - 8fps at 18MP will demand a LOT of a card to empty the camera's buffer.

+1

Heck even if you buy a used 18-55IS, you'd be better off.

I've just recieved this info from Canon:

The EOS-1N is used as a comparative model because it has better weather resistance than previous XXD EOS models, but not as much as the 1D series. The weather sealing on the 7D is superior to that of the 50D, and slightly better than that of the 5D Mark II. In addition to the various gaskets and seals, the fit of the body panels where they meet is much tighter than the 50D.

Hmm... Well I'll bet its got pretty darn good weather sealing. Just don't go putting it under the kitchen faucet. :lol:

Thanks Gordon and everyone else!
It's nice to know the level of sealing on the 7D.

From the specs :
Working Temperature Range
32-104°F/0-40°C
Working Humidity Range
85% or less

I don't remember the humidity, but the Pentax K10D has similar operating temperatures. Interesting. Does this new knowledge of sealing implies that
I can use the C7 in the range -20 to 40°C provided I say in -20-0°C
conditions for shot period (~1hr) of time and ensure less condensation? or is that taking too much risk?

Sealing on EOS 1N

Postby very_confused09 » Fri Sep 04, 2009 9:20 pm

The specifications listed for Canon EOS 1N on this page:
http://www.mir.com.my/rb/photography/ha ... l/spec.htm
suggest that the camera has been tested upto (-4°F/-20°C). Only older guys may remember the details.

Besides, this page,
http://www.mir.com.my/rb/photography/ha ... /index.htm

suggests that the camera is not waterproof ......and must therefore be handled with reasonable care. Keep the camera out of salt spray and protect it from excessive moisture. If used at the beach, clean it thoroughly afterward with a dry cloth. If dropped in water, contact an authorized Canon service facility.

............ Condensation is a problem when bringing cold equipment into a warm room. If the autofocus optics cloud over, accuracy may be seriously affected. Before entering a warm room, put equipment in a plastic bag so condensation forms on the outside of the bag.


Does this mean I can USE the Canon 7D above (-4°F/-20°C) if I avoid moisture? Is that a safe statement to make?

Hi very_confused09,

I wouldn't get too hung up on the absolute letter of the law so far as those specs are concerned. No DSLR that I'm aware of is "waterproof". Canon talk about weather sealing and even with such a body the sealing is only complete when a suitable (usually "L" if my memory serves) lens is attached and even then you usually need a filter. Plenty of folks use their cameras on skiing holidays where the temperature is lower and plenty use their cameras in the tropics where humidity levels can exceed 85%. Neither environment is camera friendly over the long term, of course, and as you note the more extreme the environment the more you have to think about being kind to the camera.
