Presumably that is writing TIFF's with the UZI. Either thar or you never
learned the trick of half pressing the shutter release, which the UZI will
continue writing in the background while allowing you to take more shots until
the buffer is full (~ 7 shots at SHQ, more at HQ). It works great for me.

As Michael Meissner suggests, you must be shooting in TIFF mode, and
it does work that way in that mode. I normally shoot my 2100 in JPG
mode, and in that mode it will overlap. My mistake.

I think you will find differently. Either that, or I've got a bad A2!

Hi,

The pixel density is not greater with a 8 Mpx on a 2/3 " CCD than on a 6 Mpx
1/1.8" (or even a 5 Mpx on a 1/2.4"). You need to stay at 50/100 ISO to have
No/Low noise. 200 and 400 are usable for A4/A5 prints.

Agree. Even at 50 ISO it is not a great deal to take sharp shots at 280 mm
equiv in daylight. You just need to watch if you can reach 1/250 sec and if not
either zoom out a bit or bump to ISO 100. Note that you are much steady using
the EVF than the LCD.
