The 20401 Cinema Contour Fixed Frame Screen by Da-Lite has a 81.5 x 192.0" viewing area, 2.35:1 aspect ratio, and 208" 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. 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: 2. 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: 3. Will this work with the 1.4 tele extender?

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

Q: 4. Is this lens compatible with a K-S2 body?

A: Yes! Works very well.

Q: 5. 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: 6. 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.

Q: 7. 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.

Q: 8. Hey there, can this be dismantled so I can only have the cage and the top handle mounted to the BMPCC 4k?

A: Yes, you will be able to physically separate the cage kit and use just the top handle and cage.

Q: 9. Is the focal length transmitted to the camera corrected? For example, if used with a 200mm, is the combination 200mm + 1.4x converter transmitting the info 'focal length = 280mm' to the camera? (Important for stabilization)

A: It does register if you use it with a Pentax lens. It shows 420mm with my DA*300mm F4 and 140mm with my Pentax 100mm WR. Not sure about the rest. Probably so if you you a fast lens. Dont know about non Pentax lenses.

Q: 10. 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.
