Sony's PJ line is more than just a solid set of camcorders--they also feature built-in projectors for sharing your shots, in person. The Sony PJ440 is their budget-friendly 2015 model, sitting at just under $400 yet still offering a good round-up of features.
The PJ440 has the same sensor and lens as the pricier PJ670, both with 1080p HD video at an excellent 50 Mbps bit rate. Image quality from both will be on a pretty similar plane. The only feature the PJ670 has that will nudge the video quality up a bit is the Balanced Optical SteadyShot, where the budget model has just Optical SteadyShot. The difference between the two is that the BOSS steadies both the lens and sensor, while the OSS steadies just the lens. The BOSS system will result in a bit smoother footage, but that $300 price difference will probably be more noticeable for most users.
The remaining differences between the two options are largely convenience features. The PJ670 has more built-in storage, with 32GB of flash memory compared to 8 GB. The PJ440 is a bit lighter, but also has a smaller LCD screen as well. Both feature a built-in projector, but the quality on the 440 isn't as high, with 13 lumens instead of 25.
We've given Sony PJ camcorders high marks in the past, and with a larger bit rate, the PJ440 offers a bit of a boost and still comes in at under $400. Note, though, that the PJ440 cuts back on zoom over the older PJ380--though currently the newer model is actually about $200 less. The PJ440 is available beginning on Valentine's Day 2015.
