The 20393 Cinema Contour Fixed Frame Screen by Da-Lite has a 40.5 x 95.0" viewing area, 2.35:1 aspect ratio, and 103" diagonal.

The HD Progressive 1.1 Perf surface has a 1.1 gain, 170° viewing angle, and is ideal for applications where projector brightness and screen size require an increase in gain. The white surface offers true color reproduction and fidelity. The perforated vinyl surface allows for the installation of speakers behind the surface. HD Progressive 1.1 Perf can be cleaned with mild soap and water, and is flame-retardant and mildew-resistant. It is also GREENGUARD GOLD Certified. Black backing on the back of the viewing surface prevents light bleed-through.

The aluminum frame is 3” wide by 1.63” and is covered with black Pro-Trim fabric, which absorbs excess light around the viewing area. The frame is slip-jointed at corners and joints. The screen also includes standard wall-mounting brackets.

Related Questions and Answers

Q: 1. Is this lens compatible with the full frame K1?

A: Yes, image coverage varies from APS to almost full frame depending on zoom setting. Very sharp, fast enough auto focus for a fair amount of keepers for birds in flight. Easy to crop final image in printing. I like it.

Q: 2. I own a Pentax K-3 with several lenses. Two of them are Sigma's. I am planning to use this coverter on my Sigma 70-300mm F4-5.6 APO DG Macro. Is this a viable choice to extend my capabilities? Sharpness? Loss of stops? Thank you!

A: I use the converter with a K-3 & a Pentax 300 mm F4 lens. As everything is Pentax all the lens functions are maintained and the camera recognizes the set up as a 420 lens. The set up dropped 1.6 F stops. Images are tac sharp!

Q: 3. THIS SHOULD WORK WELL WITH MY NEW PENTAX SMC DA 18X270 SDM LENS F3.5-6.3 ED, CORRECT ?

A: Checked the compatibility list that came with my DA 1.4x and it does not list this lens as either compatible or Not compatible. To be sure you might want to check with Ricoh, though it does work with the 50-135 and 55-300 so I don't see why it wouldn't. You also may have to update your camera to the latest software for autofocus function.

Q: 4. Will this lens work on a Pentax 55-300 lens? Thanks. Steve

A: You may or may not be happy with the results. Bear in mind that teleconverters are designed to work properly with prime (fixed) fast lenses...f4 or faster. On zooms, even on fast zooms like 70-200f2.8, the results will not be that great. 55-300mm.... Probably not worth spending $$500 for a TC since the performance and quality will be marginal. I don't like it in my 70-200 f4 or f2.8

Q: 5. Will this also fit the Blackmagic Design Pocket Cinema Camera 6K ?

A: Yes, the following protector LCD screen is made and designed for the Blackmagic Pocket Cinema Camera 6K Pro.

Q: 6. I have a Pentax P3 (still shoot film) Does this lens focus manually?

A: Yes it allows manual focus. But there is no aperture ring and the aperture control is only compatible with newer cameras. Exposure control with this lens may be impossible with a Pentax P3.

Q: 7. Is this lens compatible with the Pentax KP?

A: This lens is fully compatible with Pentax APS-C DSLRs such as the KP.

Q: 8. Is this lens compatible with a K-S2 body?

A: Yes! Works very well.

Q: 9. Can I use this lense on a canon c300 m III, s35, like a "normal" filmmaking lense ?

A: Yes, although you would need to use the optional EF mount adapter - https://bhpho.to/33v2JZ3

Q: 10. What does plm mean?

A: Some lenses include SDM (supersonic direct-drive motor), DC (direct current motor) and PLM (pulse motor) in their lens names. These lenses perform the AF operation using the motor drive in the lens barrel. This enables a quieter and smoother AF operation than body AF operation driven by the focusing mechanism motor inside the camera body, and enables an easy, comfortable focusing operation. The SDM supersonic motor includes a brake mechanism for allowing high-accuracy speed control and position control. Lenses that employ a drive mechanism which directly links the PLM and lead screw are not only silent, but offer high-speed, high-precision AF operation.
