Lowepro Flipside 200 Backpack:

I decided to pickup the Flipside 200 to compliment my larger Kata R-103. This bag is a new line just released from Lowepro with the unique feature of opening only on the side which faces your back when worn. This adds to the security of the bag since no one will be able to open it without you knowing about it. I chose this bag to replace my shoulder bag for occasions when I know I only need a few things with me and not the whole kitchen sink. The bag will fit my Rebel XTi with 70-200mm f/2.8L IS either mounted or stored to the side. There is also room for my two other short lenses. The fit is snug but it does the job and will carry only what I need to keep weight down. On one side there is a mesh compartment for a water bottle and on the other a zipper compartment for CF cards, spare battery, keys etc.

Lowepro has also included sternum straps and a smallish waist strap. There is also a built in tripod/monopod holder but it seems quite small. Overall I am quite happy that it was just large enough to carry the few select items I wanted and with the low price I can't complain!

EXPLORED??? You got me, I guess that crazy algorithm picked this shot. #312 in interestingness on 09/10/2008.

5 different ISOs images of the same scene at 100% crop. The varying levels of image noise are quite apparent side-by-side.

Results:
- 100 and 200 ISO perform quite well
- 400 isn't too bad
- 800 is ok in a pinch
- 1600 is nearly unusable if the image is going to be under any kind of scrutiny

Hope this helps anyone with questions regarding the XTi's ISO quality.
