Key Advantages

The Sony SLT Alpha A33's key advantages include its high-speed continuous shooting at 10 fps with autofocus, which is exceptional for action photography. Its translucent mirror technology provides fast and accurate phase-detection autofocus even during video recording and live view shooting. The in-body SteadyShot INSIDE stabilization works with any compatible A-mount lens to reduce image blur. The camera offers a bright and high-resolution electronic viewfinder that helps precise composition in various lighting. Its compact size compared to DSLRs enhances portability while maintaining DSLR handling. Furthermore, versatile video recording options with manual controls enable creative videography.

Limitations

Despite its innovative design, the Sony SLT A33 has limitations such as relatively low battery life compared to DSLRs due to the electronic viewfinder and constant live view usage. The sensor's maximum resolution of 16.2 MP may be considered modest by current standards. Its HD video recording is limited to 1080i format rather than full 1080p progressive. Some users have noted that the low-light autofocus performance is less effective compared to competing DSLRs. The camera's menu system and user interface are often described as complex and less intuitive. Lastly, the translucent mirror design slightly reduces light reaching the sensor, impacting image brightness in certain conditions.
