OK Harry - A620 vs A640

Thankfully I have standard test areas like Steve's Digicams and Jeff Keller so I can compare .. here are 100% Crops from the A620 at ISO50 and the A640 at ISO80 - both have been sharpened to the same degree to take out in-camera sharpening difference variable as much as possible ........ these are NOT Resizes - they're crops from the original 12 and 7Mp images .

Two big Caveats are 1:- I wasn't standing in exactly the same spot for the first one, I was further away for the 650 shot

2:- the exposure is thankfully the same but 620 shots were shot in November 05 and the 650 ones now so trees etc are different..

Anyway - at pixel level , the 650 looks much the same (only it looks closer due to the higher rez) - ISO80 looks as clean as A620 ISO50 which is also good news..
