The T77 put up some impressive performance numbers for its class. Shutter lag in particular was excellent at 0.3 second in brightly lit conditions and 0.6 second in dim (a lag time we usually get in good lighting). From off to first shot takes 2.1 seconds and it's ready to take another photo in 2.2 seconds. Turning on the flash only drives that time up to 2.8 seconds. The T77 also has a good burst speed of 1.7 frames per second.
Considering how small this camera is, photo quality is respectable with very good color (though reds and whites tended to bloom), white balance, and contrast at low ISO sensitivities, though there's some visible lens distortion on the left side, which is common in this class of cameras. Photos printed up to 8x10 inches in size were fine quality, though all photos generally look soft. Viewed at 100 percent, we saw some chromatic aberration (purple fringing), and off-center elements of scenes look fuzzier as sharpness degrades quickly from the center to the sides. Noise suppression in the pictures becomes noticeable at ISO 400 and starts to seriously obscure detail at ISO 800; we don't suggest using higher settings.
The 640x480-pixel resolution video captured by the T77 is better than most video we see from ultracompact cameras. You also get full use of the optical zoom, and since it's internal, you don't hear it moving in and out while recording movies.
The Sony Cyber-shot DSC-T77 is a very good ultracompact camera. While I like Sony's touch-screen interface, it's definitely not for everyone and can easily get tedious and frustrating some users.
