Canon PowerShot A570 IS Full Review
Compared to...Casio EX-V7
The A570 IS has an unusual feature set that doesn't really go 'head to head' with any obvious competitors; the 4x zoom range is longer than most budget models but shorter than the 6x or so that constitutes a true 'big zoom' camera. There's also the issue of full photographic control to think about... For the purpose of this review we've picked the similarly priced camera for comparison, the Casio Exilim EX-V7. It too offers a 7MP sensor and a fair amount of manual overrides in a compact shape (although the Casio sports a 7x zoom lens as opposed to the A570 IS's 4x zoom). We've included studio comparisons at each camera's lowest ISO, ISO 400 and ISO 800.

Color on both cameras is bright without being overdone, the Canon adding a little bit more punch, but overall both cameras produce realistic and fairly accurate output. In terms of general detail levels across the frame the Canon is clearly taking the lead, with surprisingly good edge-to-edge and corner-to-corner sharpness (the output is a little soft, but it sharpens up nicely). Say what you like about Canon but it's to their credit that a budget camera like this can not only offer a useful range of photographic controls but also produce output that would put a lot of more expensive models to shame.
