Referring to the famous Japanese photographer Kimio Tanaka (Kimio Tanaka), who has published interesting information about the products Pentax, the source was supplemented with detail plans for Pentax, as reflected in the recently updated chart of issue lenses. Reviews for each of the six items of the plan are given below and numbered according to the illustration.

Стали известны некоторые подробности о запланированных к выпуску объективах Pentax

1. Standard zoom lens DA (APS-C) will have a constant maximum aperture of f/2.8 and refer to the range of ★. Currently plays that role model smc PENTAX-DA★16-50mm F2.8 ED AL [IF] SDM. According to Tanaka, most likely, the novelty will be an updated version of this lens, perhaps with slightly altered focal range. At its output you can expect at the end of 2020 or in the spring of 2021.

2. Wide-angle lens with a fixed focal length and a large maximum aperture and full-frame will almost certainly include a line of ★. With a focal length of the manufacturer has not yet decided, but it will likely be equal to 24 mm. Other options considered — 28 and 35 mm. Maximum aperture is equal to f/1.4. This lens will be released before the end of 2021.

3. On the extreme wide angle lens with a fixed focal distance data while almost no, it is not even clear whether it will be full frame. Most likely, the focal distance is 20 mm before the end of 2020 seems unlikely.

4. The model layout HD PENTAX-D FA★85mm F1.4 was shown at CP + 2019. This lens, along with already released a similar model with a focal length of 50 mm and projected wide-angle model (see paragraph 2) creates a series of fast fixes high class. Its output is expected next year.

5. Model HD PENTAX FA D FA 70-200mm F4, the release of which in the previous graph have been scheduled for spring this year, apparently, is not ready yet. Anyway, spring has arrived, but at the exhibition CP+ was not shown even the layout, and the release schedule is gone. It is still possible that the lens will be released this year.

6. Zoom telephoto lens will probably cover the focal range of the 55-300 or 70-300 mm. It will be full frame, and its strengths are the small size, weight and price. Of course, it will have to live with a small maximum aperture — что0нибудь in the manner of f/4.5 to f/5.6 or even f/4.5-f/6,5. This lens will be released around 2021.
