Default Thanks Frank......

Thanks Frank.....

This is all about me finding a way to keep my camera out of the extreme cold. I should have given more details in my post (sx20is). Thanks for digging that point out.

By this you mean my sx20is may not react the same as your Sony?

I did this (outdoors) the same shot three times (a number of shots, three times actually). Not sure if you'll be able to see the difference in these pictures.

#1...with A/F blocked (inside a fleece bag).


#2....with the A/F turned off



#3....A/F turned on
