1:1 Magnification RatioThe SEL30M35 has a 1:1 magnification ratio so that subjects can be captured at full size on the camera's image sensor. This makes it easy to shoot quality macro close-ups of flowers, insects, and small objects.
Made for moviesThe SEL30M35 performs equally as well when shooting video. Thanks to an internal stepping motor and rear-focusing design It has optimized video performance for smooth, quiet operation essential for high-quality movie capture. Additionally, the filter mount does not rotate during focusing for hassle-free polarized filter use.
Smooth Manual FocusingAn easy-grip focus ring on the lens barrel gives you a solid "hands-on" feel in manual focusing. Additionally, Direct Manual Focus (DMF) allows you to focus manually after AF lock-on without the need for any switching. This can be extremely useful in situations where AF can?t lock onto the subject accurately, or when AF locks onto a point that does not match your intention. Electronic manual focus technology was originally developed for professional Sony camcorders to ensure smooth, precise focus control.
Aspherical/ED glass elementsThe SEL30M35 offers excellent image quality throughout the entire image area, with high contrast and minimal chromatic aberration from infinity to 1:1 magnification at all aperture settings. ED glass is used for the G4 element, minimizing chromatic aberration and color bleeding as well as multi-coating throughout for exceptionally clean, clear rendering
