Pentax DA560mm f5.6 sample photos from K-3 (Post#19 add samples with HD1.4x)

dsport

This lens impressed me very much.
If someone is going to say that this lens is no good because of its simple Telescope-type optical construction, then I would like to say sorry, you are totally wrong.
I agreed that the bokeh might not be as smooth as the FA*600/4 or FA*250-600/5.6. However, the image fidelity and cropping ability is much better than the FA*600/4 or FA*250-600/5.6.
Yes, this lens is expensive. But I bought it second hand from Japan in a reasonable price. If you would like to take wildlife pictures with a Pentax Dslr AND a Pentax branded super telephoto, I would recemmend this lens. But find a second hand one if you could.
Lastly, if you were unable to take good wildlife pictures with this lens, then sorry again, it might be your inadequate skills but not the capability of the lens itself.

Pros:
- DC motor drive
- High definition power with great details in images
- light weight and is able to handheld (Half of my pics below were taken by handheld)
- weather sealed
- AF workable when using with Pentax HD 1.4x tele-converter even in moderate light condition

Cons:
- Slow AF speed when compared to Canon and Nikon (Yes, you might miss some shots if using Pentax)
- f5.6
- some CA (But not as serious as FA*600/4 and indeed DA560/5.6 is much better)
- overpriced if bought it new

Thanks for watching.

以視角計, 等效 800mm 既重炮唔貴 wor.

沒有等效的，560mm就是560mm，等效只是廠商為自己推銷的論點。
說它貴是因為：
1. 鏡片組合並不複雜，鏡片數量已經少，而且光學組合程式並非全新設計，Pentax只是為它加上了自動對焦。
2. 全新售這個價錢，但仍然有CA是不可接受的。
3. 看看Sigma 500mm f4.5的售價。
4. 電子科技欠奉。連基本的對焦記憶也沒有。
5. F5.6 光圈。

基本觀念, 專為唔同篇幅設計既鏡頭, 自然係唔同實體焦距.
不過係用 35mm 等效焦距做 reference, 最後都係要睇視角對應篇幅.

RX-100 個鏡頭係 10.4mm - 37.1mm for 1", 35mm 等效就係 28mm - 70mm. 你唔會用呢個鏡頭放起 135 系統上話係 10.4mm - 37.1mm 既 fish-eye zoom.

DA16-50 係 16mm - 50mm for pentax APSC, 35mm 等效就係 24mm - 75mm. 你唔會用呢個鏡頭放起 135 系統上話係 16mm - 50mm 既 Ultra wide zoom.

DA560 係 560mm for pentax APSC, 35mm 等效就係 860mm.  24mm - 75mm. 你唔會用呢個鏡頭放起 135 系統上話係 560mm 既 Tele.

sony E16 for sony e-mount APSC, 35mm 等效就係 24mm, 放起 e-mount APSC 你睇到既係 24mm 視角, 放起 A7 上你都係睇到 24mm視角, 不過多左成象圈, 唔會 wide d 變 16mm既視角.

除非果枝鏡既光學係對應唔同篇幅, 如 canon EF, pentax DFA, FA, 同埋部分原本係 FA 既 DA 鏡.

不打算在此討論焦距等效的問題，反正明白我説的是什麼，自然會明白。不明白的，我也不打算教明白。
而且不同意我對於此鏡的評價也沒有所謂，反正我也不同意網上另外一位對DA560的評論:

小弟只是想還此鏡頭一個公道，也給笨友多一個參考。其他的對我來說都不重要。

我無咁既財力同體力去支撐 300 以上既重炮.

理論同觀念都算識少少, 有咩錯誤都還請賜教賜教
