I didn't dare since I never liked the results viewed on screen...

Think I'm going to choose one image and give it a go!

"Buyer told me they always go for the "bigger files". It's the third time this happens and on all the three images destination was for "outdoor/billboard"

Well then your 'buyer' is nuts - perceived resolution is directly related to viewing distance.

You could shoot billboards with a 6MP camera (and it's been done for years). Viewing them from 200ft away (or more) in a car means you would make out zero pixelation even at 72-94 dpi if the image were 20ft across.

I missed that "buyer wants" thing. Did they tell you exactly wat they need? Are they going to have your image touched up?
It's funny... my cell phone has more native resolution then my DSLR!

Thay did, they want LARGE files for large printing on billboards/outdoors like the ones I show a few posts back.

No.

Seems everyone is just looking at the printing question, but iso is also a concern.

I did print a image to test and it did not satisfy me. For high iso night images (like the one I pasted as example a fez posts back) seems FF is also the best to the job

K-7 at ISO 1600 is no problem and the K-5 supposedly just laughs at such a "low" ISO setting. However, it sound like you want a 5DmkII so gor for it.

Sounds to me like you've made up your mind. Enjoy your new 5D-II.

Edit: Dam! Too slow!

Printed pics are not billboards... Offset printing is far from 300dpi...
If it's for billboards, then iso/resolution are really superfluous...

A 8MP camera can output a billboard as big as the distance it is viewed from, without any interpolation.
With careful doctoring, the pic could be enlarged further, or seen from closer.

But all this is of no use if your buyer just want huge MP...

Do yourself a favor, call up a company that has billboards up in your area and ask them what the file specifications are. If necessary, just tell them that you have a potential client that is interested in outdoor advertising. They should be able to give you a little more detail than "LARGE files". They will tell you how many megapixels they need, the dimensions, and how they want the file (JPG, TIFF, RGB, CMYK, etc..) and whatever else.

Then take the each of the linear dimensions and multiply them by 1.25 or 1.5 to give you a little breathing room, because media sales people will give you the absolute lowest acceptable values (lower hurdles = more sales), while the production folks who you won't be speaking with will have higher IQ standards.

Then find a camera that satisfies those linear dimensions and has the ISO capabilities to boot. Don't just go by megapixels, because billboards are usually very wide and you'll be throwing away a lot of the pixels on the top and bottom of the image.

Then take this information and educate your client. They may be making decisions based on wrong assumptions and turning down otherwise good photos from good photographers.

+1. The OP should try to view a billboard up close. They'd be appalled at the IQ. If that's not possible, look at these messenger bags made from recycled billboard material:
