The 20391 Cinema Contour Fixed Frame Screen by Da-Lite has a 78 x 139" viewing area, 16:9 aspect ratio, and 159" 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.

Q: 1. Will this work with the 1.4 tele extender?

A: No, that lens is not compatible with a teleconverter.

Q: 2. Will this lens work with a K200D?

Q: 3. Hello, again! Is Angenieux EZ compatible with anamorphic adapters? Which Adapter is the most recommender?

A: We are not aware of an anamorphic adapter for this lens. If you are looking to invest in PL lenses for Anamorphic Shooting your best bet is to purchase Anamorphic PL Mount lenses.https://bhpho.to/2tVXwaK

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. 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: 6. 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: 7. Is the lens metadata? /I?

A: You will need to use the Angénieux MSU-1 & MSU-1A Universal Cine Servo Units for lens metadata and /i Cooke communication.

Q: 8. 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: 9. Will it work with Pentax K-5 and 150-450mm 4.5-5.6 lens?

A: Yes, its compatible but you will probably lose autofocus on the long end.

Q: 10. does this work with HD Pentax-DA 55-300mm f/4-5.8 ED WR Lens?

A: Yes! I've shot some tack-sharp daylight wild animal photos with the Pentax DA 55-300mm/1.4x Rear Converter combo. Note: Since you'll lose an f/stop with the teleconverter, the combo will work best for outdoor tele-zoom photography in favorable lighting conditions.
