Sensor size...

For the record, the DiMAGE 7 uses the same size sensor as the A2 and it's actually gives fast shutter speeds for shooting IR. In daylight I often shoot my IR images at 1/15 or 1/30 sec at 100 ISO using the Hoya R72 filter and it doesn't contain a hot mirror filter.

I don't understand. My understanding is that the DiMAGE 7 is (like the A1) a 5 megapixel chip, while the A2 is an 8 megapixel chip. How can you say these are the same size?

They are the same size sensor. Both sensors are of a physical size known as "2/3rds." Please note that pixel count (Megapixels) is separate from the sensor size.

Actual dimensions of the DiMAGE 7 and A2 respective sensors is 8.8 x 6.6mm , making them amongst the biggest sensors ever fitted to what are now known as "super-zoom" type cameras.

Image diagonal is 11mm. Crop factor compared with FF35mm is 4 , making the frame area approximately 1/16th that of full frame 35mm film.
