All the 'normal' super-tele lenses.
Those are extremely costly lenses. I doubt Pentax have the economy to launch a series like that. But I have a much cheaper alternative:
Take advantage of TCs. Basicly a 200mm f/2,0 and a couple of dedicated high quality optimized TCs: 1,5x and 2x, that may be combined. That way we only need one very expensive lens, and a set of TCs that fill the needs of 4 very expensive lenses for a total price of less then 1,5. This will put Pentax on the fast lane in the telephoto competition. The TCs may be standalone K mount, or have a special mount or be built into the lens, like the Canon 200-400 f/4.

A polariser is not very useful on ultra wide angle in my opinion. Difficult too. I would rather have a rear filter slot. Or 10x better: A camera with a built in ND filter that can be slided in front of the shutter. A "lower ISO simulator".

Originally posted by Enrique S Toso Now I have this idea: Put an acelerometer and a gyroscope in the camera, and make them record the information of the movement of the camera, and syncronize that with the video file. Then, make a software that makes the image steady. Yes, like Instagram Hyperlapse, but in a DSLR camera.
That is a very good idea. The camera should record slightly more then 4K resolution to file and crop that to 4K in a post processing software (or in camera). Predicting future camera movement in real time is difficult and may produce sudden jumps if the prediction is wrong. When cropping to 4K in post process the software will know the camera movement both before and after the frame that is currently being cropped. This will make more steady videos then stabilizing in real time.
Sorry for answering an old post, but I think the wish for better video is relevant this year as well. I'll just add some comments about a 4K video optimized sensor. It could also be a very good sensor for high ISO performance and high speed still shooting. A combined sports still photo and video camera. The sensor should be 3:2 format because of still photo and have just slightly more then 3840 or 4096 pixels horizontally. Maybe 4200 x 2800 pixels (11,76 Mp). It should also be optimized for fast readout, maybe only 12 bit ADC in all fast modes. 4K 60p and FHD 120p would be excellent for video. That should mean up to about 45 fps full readout of still images to the buffer. Fast readout needs fast storage. A list of qualified M.2 SSDs in stead of SD and USB3 transfer to the PC should be fine. Large pixels also means potential for very high dynamic range and very good high ISO performance. For all slow modes there should be possible to enable a 16 bit ADC. Pentax should deliver this sensor feature wish list to Sony now and work out the wrinkles in collaboration. Decide between APS-C and FF and the amount of shutter roll. Pentax will of course be creative about features like focusing screen, multi channel audio input, smooth zooming and more.
