Lenses / Re: 100-400 f4.5-5.6L or 2x extender

this site should help you decide
I went with the 100-400.

are you sure it's front focusing?
at 1.4, your DOF can be minimal (depends on the distance of subject)
here is a calculator for you

why f8? Could use f5.6
why ISO 200? using f5.6, you can use iso100
light is a bit on the harsh side, due to time of day and altitude (guessing).  Consider a circular polarizer or a variable nd filter or ideally own both.

Why not use f/8?  I shoot a lot of landscapes and rarely use a larger aperture than f/8 - am usually between f/8 and f/16. 

You have to be careful which VND you use as many of them leave colour casts.  yes these can be removed, but you will remove not just the cast, but also other colours at the same time.

using wider aperture(as long as it is sharp enough), you can speed up the shutter and minimize blur due to winds blowing trees around as an example.

it's pretty simple in my opinon.
I shoot with a 50d and 24-70 2.8 so it's hardly a stealth thing
Be courteous, polite, apologetic, and comply regardless of region, country.  I have shot in Japan, across Canada, Mexico, Brazil, across USA.
You are going to get a range of reactions from people, even varying reactions in the same area.
If someone intimidates me, I apologize and put the camera away and walk away.  No shot is worth offending anyone or getting in a fight or a brawl.
Are you earning a living shooting street shots? 
I have even deleted the picture in front of the person to show that I am not going to do anything.
If you publish a picture of someone without a release and the subject finds out, they can come after you.  Find a good lawyer.
Easy to defuse a situation.  I am never defensive nor aggressive.  Show respect, apologize, delete the picture if requested, and walk away.

other things to consider
humidity can affect how light travels
distance.  the further away you are from the subject the more light diffraction you will encounter

50d shutter speed up to 1/8000
6d shutter speed up to 1/4000
If you can't freeze action at 1/8000, it's probably not the camera. Look in the mirror for possible answer

so you are saying depreciation bothers you.
5d's target consumer is pro's, who'll buy this cameras to make a living.  They are not going to complain about depreciation because they are making money with the equipment.
You can't afford depreciation, you can't afford the product.
Assume you buy a dress shirt for $50 today, you wear it, and try to sell it in 3 months.  How much do you think you'll get for that shirt?!!! $25?  You would not complain about that because you got your money's worth.
Go out and get your money's worth with the gear you bought.

CPL like mentioned already.
Also a dry bag.  While in hotel/house, where it's around 70 degrees, put your camera in the dry bag (a thin one is preferred as it will adapt to the temperatures more quickly). Pack the camera and head for the slopes. Take the camera out and you should have no condensation.
After you are done for the day, put the camera back in the dry back and head back to the hotel/house. Once in the hotel/house, leave the camera in the bag for about 30 min for the camera temperature get up to room temp. Remove the camera from the dry bag and you should have no condensation. 
Same process should be followed when headed to the tropics.

Like asking if you can afford the monthly payments on Porsche 911.
if you have to ask, you can't afford it

EOS Bodies - For Video / Re: Tripod - Help
« on: October 24, 2012, 03:26:35 PM »
you get what you pay for with tripods
I bought a $300 tripod.  It's foldable, it's heavier by almost 2 lbs compared to carbon fiber units, the head is not perfect and sags with my 50d and 24-70 2.8 mounted (meaning, I set it at a certain level and droops 1-2mm after I let go of the body).
I read this several years and did not follow the advice.  I should have.  Save up and buy the right one the first time.  Now, I am $400 invested and wishing for more; wishing for the $700-800 unit I should have bought to begin with.

EOS Bodies / Re: Dynamic Range & Camera IQ
« on: September 26, 2012, 03:47:37 PM »
I'm a 550D user who has just yesterday ordered a 7D. I've never even looked through the viewfinder on a FF camera, let alone held one.

I do know my way around my camera, but on these boards I keep hearing people talking about Dynamic Range when comparing cameras or making wish lists of improvements.

Can somebody please point towards a good explanation of DR and also comparisons between similar cameras (e.g. D800 and 5D M2/3) so I can understand it better and how it impacts me? Also any explanation of camera IQ would be helpful.

did you think 7d is a full frame camera?

I understand why your perspective
no, they are not crazy.  Just geeks
They like to say theirs is bigger or straighter or sharper or better packaged or better functionality or it's more compact.  Oh, that's what they like to say about their Canon gear, too.

yes, in time everything (almost) gets replaced.
The combustion engine has been around for 100 yrs, but with the advances in other technologies(battery) electric cars are starting to look more and more appealing.
The human drive for improvement is one of the great things in this world.  The DSLR will be replaced.  Don't ask me when.
