浅见：现有型号EF300mm F2.8L IS II USM已经活跃于包含运动摄影在内的多种场合。因此，随着EOS R系统的不断发展，我们开始考虑开发一支能够继承300mm f/2.8镜头特有的高速、浅景深(背景虚化)和强烈压缩效果的镜头。于是，扩大拍摄范围这一构想应运而生，我们要打造一支远摄变焦镜头，几乎可以适用于包括室内外运动、人像、野生动物在内的所有摄影类型。
早川：我们还曾想要研发一支能够满足比RF70-200mm F2.8 L IS USM焦距更大、比RF100-500mm F4.5-7.1 L IS USM光圈更大的变焦镜头。从媲美定焦镜头的光学性能以及小巧轻便且机动灵活的角度综合考虑，100-300mm F2.8最适合不过。

浅见：我们的理念是开发一支大光圈L级远摄变焦镜头，可适用于多种摄影类型，便携性出色并且画质与定焦镜头不分伯仲。开发镜头的过程中，我们一直不忘初心：实现100-300mm全焦段高画质，安装增倍镜时高画质，重量进一步减轻。

五十岚：EOS R系统是基于卡口核心设计理念打造的。系统的特点是相机卡口和镜头卡口上都有一个金属卡口环 ，镜头安装到相机机身时，营造出强烈的一体感。我们为RF100-300mm F2.8 L IS USM设计了全新的宽幅卡口环，充分考虑到镜头安装到机身时的平衡感。作为大光圈L级远摄变焦镜头的全新旗舰机型，RF100-300mm F2.8 L IS USM将引领今后产品线的风格潮流。

早川：我负责过EF400mm F2.8L IS III USM (2018年上市)的机械设计。当时，我们成功将前型号EF400mm F2.8L IS II USM减重1kg以上，这让我体会到了什么叫迭代升级。EOS R系统在同一时期问世，RF卡口让进一步减轻镜头重量成为可能。RF100-300mm F2.8 L IS USM是我们积累至今的专业知识的结晶。

片寄：进行光学设计时，我们在前端镜片后面连续放置三枚凸透镜，从而将后续镜片的直径减小到极限。我们还通过采用大口径玻璃模铸(GMo)非球面镜片，减少镜片数量。在选择玻璃材料时，我们不仅考虑了光学特性，还考虑了比重。此外，我们尽可能做薄凹透镜，实现了高画质和大幅轻量化。

浅见：尽管我们说镜头更小巧、更轻量，我认为用户仍会觉得数值上的重量和实际拍摄时握持镜头的手感是有差异的。因此，我们非常在乎成品镜头要让用户感觉轻巧、易于操作、想在手持拍摄时使用。

浅见：由于机动性和便携性提高，我们期望摄影师们将这支镜头用在需要辗转多个室内室外竞技场的国际体育联赛中，还有用于新闻报道、野生动物摄影等。
此外，我们还期待在音乐会、剧院、时装秀等现场，摄影师不能靠近被摄体或照明情况会变化的摄影条件下，通过使用防止被摄体模糊的高速快门进行远摄，可以大幅扩大拍摄范围。

片寄：RF100-300mm F2.8 L IS USM采用了萤石镜片和UD镜片结合镜片组来降低每组镜片产生的色差，从而实现高画质(尤其在远摄端)。萤石镜片比重较小，有助于减轻重量。我们在光圈附近采用三枚UD镜片，减少了画面中心的色差。还有一点，我们在最后一组镜片中采用了大口径GMo非球面镜片。这对于减少镜片数量和实现高画质至关重要。另外，对于300mm f/2.8镜头来说，许多用户注重虚化的美感，也关注大光圈。我们的设计就是在彻底抑制镜头色差的同时，还能保留柔和的虚化效果。此外，为了抑制鬼影，我们还采用了空气球形镀膜技术(ASC)来有效抑制光线反射。

长冈：我们采用有2个NANO USM的电子浮动对焦控制系统，这一系统已在RF L级远摄变焦镜头中得到验证。NANO USM可控性佳，操作声小，适合拍摄视频和静止图像。

早川：我们做了防尘、防水滴测试、防沙测试和变焦转动耐久性测试，都能确保镜头品质满足专业摄影师在拍摄时对L级镜头的特殊要求*。我们通过模拟测试完成减轻重量和增加强度两个工作，最终我们在镜头更轻和更坚固之间实现了良好平衡。
为了追求小型化、轻量化，同时还采用镜片组位置靠近卡口的光学设计，于是我们取消了插入式滤镜。结果是，没有了会影响镜筒强度的插槽，就能够降低外镜筒的厚度，于是进一步减轻了重量。
