My guess is she must know it, and she's doing it intentionally.

For my company, I need more TP.

I was there year ago, and it was quite nice. I didn't have half the gear you have, but still I got plenty of good photos. With your gear, you'll be fine.

I wasn't so much for the birds, so can't comment on those but for most others I think the 600mm is even too much occasionally. How you planning to carry all those around when hiking? Or you just take one or two bodies with one lens each for hike? Only one time I was "short", there was group of goats (or something climbing the mountain side), and my 7D + 70-200 + 2x wasn't nearly good enough for that. 400 w/ 2x would have been better, but 600 w/ 2x (on 1.6x crop) would have been probably about enough.

I saw bears couple times (from car), and I was always carrying the bear pepper spray just in case. I wouldn't be comfortable camping outside.

I have experienced the IS causing a blurry picture when on a tripod using lenses that do not have tripod sensing.  So in that case I now turn off the IS when using a tripod with those lenses.

Interesting, can you share the images and also setup/settings?

Good job Neuro! Thanks for doing the tests.

Interestingly the middle version is almost stabilized but not quite, so I guess the IS just kicks in but needs just a bit more time to really work 100%.

The copyright is too intrusive, especially on the second pic is just really ruins the whole picture. Apart from that, the pics are nice.

The water-detector is typical in cell phones. Every smart phone also has 3-axis accelerometer, but it's up to the software to determine if they measure 24/7, and record it in case of drop/hit. If I was manufacturer, then yes because they don't consume next to nothing on current, and it's great way to indicate abuse.

As for cameras, I have no idea if they have similar feature. It'd be nice if they told how they came to that conclusion.

Long time ago the product my company sold, got returned from the field with a note "it just broke down, send new unit".

The units ran hot always, and they had peltier cooling elements on them. At the time the peltier element was possible to wire wrong way, so it'd heat the device instead of cooling. Unknown to the customer, the inside thermometer was logged, and as I connected to the device with my PC, I read max temperature somewhere around ~90°C (~200F), when it usually ran under 60C (<150F) at max. I emailed the customer if the "it just broke" -unit they had accidentally connected the peltier the wrong way. First they said no, but when I told that we actually read that the unit overheating way beyond what it should be able to do by itself, they confessed that "for short period of time" the peltier was connected wrong.

So no warranty for them.

As for OP, there's chance a kid knocked the camera down from table or something, and it can break even without any visible damage. Without knowing all the facts, it's difficult to judge who's right. For low-end cameras, I wonder if they get lot of spoof warranty attempts, so they might be more strict on those.

I'm yet to see the picture where IS did hurt in any way, sharpness or other.

Only sure thing I know IS hurts is battery consumption.

Nice, maybe I should try with my 1200/5.6.
Let us know when you take a picture of ... Jupiter  ;D

First shot it didn't fit the screen completely so I had to step back couple feet.

Assuming your monitor is calibrated: if it looks good, then it's good.

If you want to go more high-tech, then the cards and such work too.

Often I go by the eye. If it looks wrong, I tune the sliders. Also it's bit subjective, so many times I switch between couple photos, and tune until they all look good. If you stick only to one photo, often after tuning it to "look good", and you come back later, it doesn't look good anymore.

One of my 7D @ ISO3200 photos was printed on canvas, about 5x3 feet. It looks awesome even when looking really close.

Would it have been better if I already had 5D3 by then? Actually not possible, because 5D3 wasn't released yet. But with time machine, yes. But it was still good enough. 7D is awesome, I try to keep it at max. ISO1600, but still 3200 is ok when good exposure.

BTW, tpatana, nice shot.  Did you use fill flash?

Thanks. That's one of my favorites from this year. Sometimes I get lucky :)

I though that one was with flash, I had plenty with both flash and no-flash during the week there and can't remember each situation. But the exif says no flash so I guess I have to believe that.

So, please enlightening us about the setting...

Here's the settings from the exif:
Lens:   EF24-105mm f/4L IS USM Shot at 24 mm
Exposure:   Manual exposure, 1/100 sec, f/6.3, ISO 200
Flash:   Off, Did not fire

Like I said, you have to test and see for each situation. So e.g. if you take those settings above, you should still check how it comes at your location, with your light conditions, and tune if needed.

Like the others who have both, I don't actually use my 7D and it gathers dust as a back up in case the 5D III needs to go in for repair.

Exactly. I did use it once when I needed two bodies at the same time, but 99% of the pics come from 5D.
