• Sony Alpha 700 ($1,400 street, body only): With its larger 3:2 aspect ratio and 12.2MP CMOS sensor, the A700 captures slightly higher detail than the E-3, but color is not as accurate nor is noise as low at ISOs above 1600. The A700's AF system squeaks past the E-3's in very bright light (using a 50mm f/1.4 lens). Both cameras have image stabilization systems that gain up to 3 stops' advantage. The E-3 body is built tougher than the A700 and also sports a swiveling LCD monitor with a live view mode. The A700's larger, sharper, 3-inch LCD has a fixed position and no live view.
• Nikon D300 ($1,800, street, body only) Priced slightly higher, the D300 outperforms the E-3 in several categories, notably its faster AF speed in very low light and its maximum burst rate of 6 fps (versus 5 for the E-3.) The D300 has a fixed-position, higher-quality, 3-inch LCD that also allows live view -- with two types of AF. We'd give the E-3 a slightly higher rating for body strength, but the D300 has easy-to-master controls and a refined dial and button arrangement. Its external flash controls and AF tracking are more advanced. And JPEGs from the D300 look better at high ISO settings.
