Throw Distance Flexibility: The XJ-A250's powered 2:1 zoom gives you a lot of projection distance variation for a particular image size. For example, to project a 100" diagonal 16:10 image, you can place the projector anywhere from just under 8 feet to almost 16 feet from the screen. The zoom movement is very smooth and hitting your mark is easy.
Though the 2x zoom can be handy, at the maximum telephoto setting light output is reduced by 21% compared to its brightness potential at maximum wide angle. This is relatively little light loss compared to most 2x zoom lenses. However, since the projector already falls short of its lumen spec, using the telephoto end of the zoom may cause a further curtailing of light that is not desirable (see Brightness and Uniformity).
Illumination System Life: Lamp life for mobile projectors is generally in the 3,000-4,000 hour range in normal mode, but the XJ-A250's laser/LED light source is billed as having a prospective life of 20,000 hours. That would let you give a 4-hour presentation every day, five days a week, for about 20 years. If you plan to use your projector extensively, this can save you the cost of replacement lamps.
Powered Focus: Unlike most mobile projectors, the XJ-A250 has a powered focus ring. Just touch one of the two focus buttons on the remote, and your image will focus in seconds. The control operates smoothly, and overshoot is minimal.
Brightness uniformity. Brightness uniformity was much better than average at just over 87% with the center of the image slightly brighter than the perimeter.
Quick start/stop: Casio's new illumination system does not require the usual warm-up and cool-down times of traditional high-pressure lamps. On applying power, the XJ-A250 is up to full brightness in less than 10 seconds, and when it is time to shut down, you can pack up the projector immediately after you hit the power switch.
Warranty Provisions: Casio offers a 3-year warranty on the projector and a 3-year or 6,000-hour warranty on the laser/LCD illumination system.
Maintenance: Like most DLP projectors, the XJ-A250 has no air filter, but an occasional cleaning of the air intake vents with a small vacuum cleaner is recommended.
