Optoma ML500 LED Projector Review
No zoom. The only way to adjust image size with the ML500 is to move the projector. This shouldn't be a problem given the light weight, however. Also, once you've used the projector a few times you should have a good feel for how far to put it from the screen to get the size image you want. As a point of reference, I measured a 92" diagonal image from just over 9 feet.
Rainbow artifacts for video. Although rainbow artifacts aren't an issue for data images with the ML500, I saw them often enough in video to suggest they could be annoying to people who see them easily. That makes it best to limit the ML500 to short video clips.
The emerging new category the ML500 is part of, and the ML500 in particular, fills a niche that needs filling, with an appealing balance of size, weight, price, and brightness. Compared to pocket projectors, it's only a little bigger and heavier, but it's a lot brighter. Compared to traditional lamp-based portable projectors, it's significantly lighter and smaller than all but a few, and less expensive. And although it isn't as bright as most lamp-based projectors, it's bright enough to throw a reasonable size image that can stand up to ambient light.
In addition to small size and low weight, the ease of setup adds to the projector's portability, as does its ability to read files from memory. And the long lifetime for the LEDs promises to save lots of money in running costs compared to lamp based projectors. Add in the good performance for data image quality, its high level of brightness uniformity, and even the surprising good audio quality, and the ML500 is an excellent choice for anyone who both needs a portable projector and needs to travel light.
