The 54.0 x 96.0" Tensioned Advantage Deluxe Electrol HDTV Format Motorized Projection Screen from Da-Lite is a ceiling recessed screen with an HD Progressive 1.1 Perf finish, 1.1 Gain rating, 85° viewing angle (L/R) and Greenguard certification for use indoors. The fire retardant, mildew-resistant finish delivers true color and uniform edge-to-edge image diffusion. The white finish has black backing material for opacity and is optimized for high resolution projectors. Tensioning on each side of the seamless fabric assures a flat, undistorted surface that eliminates any chance of a skewed image.

One of the major advantages of this screen is that the fabric roller can either be factory installed or at your chosen location after the ceiling recessed, UL Plenum rated extruded aluminum white housing has been roughed in. The enables you to finish the initial installation but choose your screen finish at a later date.

The screen includes two motors; one for the ceiling door and one for the fabric. The interior roller features a quick reversal motor, oiled for life, with automatic thermal overload cutout, integral gears, capacitor, and an electric brake to prevent coasting when the screen is stopped at a chosen length. The built-in Low Voltage Control controls up/down and stop functions using the included 12VDC three-position switch that can be wall mounted where convenient. It can also be operated from an optional radio frequency, infrared or auxiliary transmitter.

Related Questions and Answers

Q: 1. Is the quality and compact size of prime lenses worth the loss of convenience compared to zooms?

A: The quality of this lens is definitely outstanding. But, I already owned several zoom lenses before I purchased this lens. I am a fan of the zoom for general usage.

Q: 2. Can I silkscreen translucent inks onto this substrate?

A: This is designed for inkjet printing. You would need to test it to see how it works with silkscreen translucent inks.

Q: 3. Does this lens work without electronic camera control? If I use a dummy mount adapter to EF, can I do manual focus and iris control? Or is the fstop only able to be adjusted by a camera that speaks to the lens?

A: The aperture on this lens would need to be controlled by the camera or an adapter with manual aperture control.

Q: 4. will it work as a full frame on the new Pentax k1?

A: The Pentax HD Pentax DA 40mm f/2.8 Limited Lens is designed for use on APS-C sensor cameras; however, many owners and users of the lens have often stated that they happily use this lens on their Pentax 35mm film cameras and the lens does cover the full image frame. As such, the lens should also work for use on the full-frame Pentax K-1 DSLR camera. (Do note this claim has only been made about the Pentax HD Pentax DA 40mm f/2.8 Limited Lens, and does not apply to other Pentax DA Limited lenses).

Q: 7. Would this lens work with the Pentax K1000 film slr?

Q: 8. Would the DA 21mm be a good lens for my K-50? I need a wide angle lens, since I am starting to shoot some photos for my friends landscaping business.

A: HI Don, I've had this lens a couple years, on my K-7. I travel for work internationaly, and am an amatuer photog. I like landscapes and a wider field of view even in city streets. It's light, guite fast and compact and seems very durable, even in extreme polar regions. I'm very happy with my pics, but there is some distortion say in city skylines and some horizons, if you use the odd looking rectangular sunshade cover made for the lens seems to help with that alot. It is subject to sunflares from sides but I often just block with my hand. I'd say I'm quite happy with it, Its well made, and I take it everywhere, but again I'm not a pro. For photos of residential landscapes it should work well, but it's not inexpensive as you've probably seen, make sure you take it along to scenic places too if you buy it! Hope this was some help, dave
