Samyang Announces the Launch of new AF 24mm F1.8 FE
with Optimised Features for Astrophotography


 



 

April 9th, 2021, Seoul, South Korea – Korean optical manufacturer Samyang Co., Ltd., today announced the latest addition to their Tiny Series lens line-up with the introduction of a new AF 24mm F1.8 FE large-aperture wide-angle prime lens, for Sony full-frame E mount cameras. The lens is tiny and lightweight to suit the smaller compact system cameras.

 

Samyang Expands the Tiny but F1.8 Series Line-up

The Samyang 24mm F1.8 FE weighs only 230g/8oz, measures 71mm/2.79 in length and uses 11 elements in 8 groups (7 special lenses – 2 ASP, 3 HR, 2 ED). It has a 9-bladed iris, 58mm filter thread and a close focus distance of just 0.19m/0.62ft.

 

Ideal Autofocus Wide-angle Prime Lens for Astrophotography
The AF 24mm F1.8 FE lens features a new function titled “Astro-Focus Mode” with an “LED index” for astrophotography. The “Astro-Focus Mode” can be operated through the newly-designed Focus Hold button. This function allows you to move the focus directly to infinity, by clicking the button when entering the Astro-Focus Mode. Since the factory default value may differ slightly, depending on each camera body, this is a convenient function that allows you to save and use the precise infinity focus value, according to your specific camera body. If the focus value set through the LED index does not match, it will be shown with a red LED. If you then click the button, your focus value will automatically adjust to the saved value, changing the LED to green.

Considering the astrophotography environment, this is an extremely useful function for those who need to spend long periods in dark environments.




AF 24mm F1.8 FE Features


Compact, with Superb Resolution
Samyang’s latest optical technology allows this large aperture wide-angle prime lens to achieve stunning corner-to-corner resolution, even at its maximum F1.8 setting. A total of 11 elements in 8 groups, with 7 special lenses (2 ASP, 3 HR, 2 ED) allow you to express your infinite creativity; especially suitable for astrophotography as it delivers awesome images with minimised spherical aberration and coma.


Shallow Depth of Field with Large Aperture F1.8

The AF 24mm F1.8 FE has a fast F1.8 aperture for crisp focus and beautifully blurred backgrounds. It gives you full control over depth-of-field so that you can isolate your subject from the background. The 9-blade circular aperture contributes smooth, creamy, natural-looking bokeh.

 

Versatile Lens for Landscapes, astrophotography and even snapshots
The 24mm F1.8 FE lens provides a wide-angle of view of 83.7˚ and a short minimum focusing distance of 0.19m (0.62ft). This allows you to take photos in multiple environments, whether indoors or outdoors. Combined with this wide-angle persona, you can freely create your own perspective with ease and creativity.


Compact & Lightweight with Modern Design
The AF 24mm F1.8 FE weighs only 230g (8.1oz) and is just 71.5mm (2.8in) in length. This small size and lightweight enhances mobility when used with compact E-mount mirrorless cameras. The matt finish, with laser-engraved font provides better readability and the tactile mounting index adds to the user convenience. Also featured is weather sealing in 5 locations, to protect from dust, light rain and snow and provide the ability to capture stunning images in less than perfect conditions.


Advanced Fast and Quiet Auto Focus for stills and movies
Autofocus is now expected to capture images accurately and quickly, but it also needs to be quiet and smooth. The AF 24mm F1.8 FE features the latest STM (Stepping Motor), this allows a larger and heavier focus lens group to be controlled more quietly and precisely, providing superb image quality in both photos and videos.


Maximising Usability with New Features
Customisable Focus-Hold Button
Pressing and holding this button will keep the lens locked to that focusing distance. The user can also assign other desired functions to the focus hold button through the menu setting on the camera body.


Custom Switch
Equipped with Samyang's Custom Switch, shooting and operation is more intuitive and simple. You can easily various functions such as Aperture Control Mode or MF Mode from the Switch and enjoy the shooting mode that suits your personal preference. More functions will be added through firmware updates in the future.


Astro-Focus Mode – NEW function for Astrophotography
When a user enters the Astro-Focus Mode, the LED index will blink red once and the focus will automatically move to the infinity position (Factory default setting value). Users can save their own/desired focus position/value with the focus hold button.

森养最佳标准画角提案解析

从人与人之间的关系乃至为了营造美丽的空间而布置装饰品时都需要保持适当的距离。那么,为了更好地欣赏美术或摄影作品,我们应该保持多少距离?

答案是相当于“作品框架对角线的长度”的距离。

표준화각 자료 이미지
표준화각 자료 이미지

为了将作品完整地纳入视野并予欣赏,保持相当于作品对角线的距离为宜。如果距离过近,将大于人眼可集中精力的50°视角而无法取的良好的欣赏效果。

为了最佳欣赏效果与最佳视角而保持理想距离也适用于摄影技术。在拍摄静止画像的摄影技术中,将等于摄像面对角线长度的焦距镜头定义为标准镜头。数码相机的全帧传感器尺寸为36x24毫米,其对角线距离约为43.26毫米,标准镜头应为多少毫米以下的最理想答案可以称为“接近43.26毫米的数据”,而难以断定是至今被视作标准镜头代名词的“50毫米”。

以往与胶片对角线长度相仿的45mm画角镜头较为常见,随着SLR相机大获成功,为了保留可容纳反射镜的空间,50mm被视作标准镜头。但是,最近随着无反相机底边大幅放大, 鉴于无反相机法兰距短的特点,需要将标准镜头的画角以45mm再度予以解释,由此开始研发AF 45mm F1.8 FE。 与35mm画角镜头相比,三阳的AF 45mm F1.8 FE将畸变现象降至最低,且比55mm画角拍摄范围宽,为人物、风景、建筑物及宠物等各种主题摄影呈献令人满意的效果。

什么是预设光圈功能?

在预设光圈功能中,光圈可以像”控制环操作音消除(De-click)镜头“一样丝滑驱动,为视频拍摄提供支持。

富士相机的设计根据最小曝光量(F-stop)控制光圈,当相机控制光圈时,会依靠短暂闪烁来调节曝光。而AF 75mm F1.8 X不会向机身传送光圈信息,这种刻意的“预设光圈功能”无需闪烁就可让平滑的曝光调节变为可能。只需控制光圈就可以使ISO和快门速度适应不同的曝光环境,因此即使采用1/2 F-stop也依然可以调节曝光。

有哪些预设光圈功能的使用建议?

预设光圈功能仅能在视频拍摄模式下运行。 建议在f/1.8光圈和A、M曝光模式下使用该功能。有关“预设光圈功能”的使用建议请参考上表。

* 预设光圈功能的使用方法

1) 设置相机机身
      AF模式 → 视频拍摄模式(“A”或“M”模式)→ 光圈值固定在f/1.8
(2) AF 75mm F1.8 X镜头设置
      将“自定义开关”切换为“模式2(M2)”
(3) 使用对焦环调整预设光圈

Dolly shot是什么?介绍摄影办法

[Dolly Shot是什么?]

一般利用带轮子的车,根据调整相机变焦的速度前后移动拍摄的技术。这导致被摄体和背景的倍率差异,从而将梦幻效应记录在视频中。

[简单用手持拍Dolly shot的方法]

Tip.如果移动距离长,相机可能会晃动,请在35~100mm区间拍摄。
1.距离被摄体约1.5~2m左右。
2.将自定义开关切换到MF和Mode3后,将视角设定在100mm左右。
3.通过调节对焦环聚焦被摄物,然后将光圈设置为F8~16。
4.利用上身和手臂,将相机靠近被摄体,将变焦操作慢慢向左(广角方向)转动。
5. 完成Dolly shot!
※在与拍摄对象更远的距离拍摄时,使用卡丁车或万向稳定器等,可以更稳定地进行拍摄。
