索尼在PhotoPlus 博覽會展出了驚人全新變焦鏡頭搭配PMW - F3先睹為快。

新的18-252mm Zoom吸引了大量的關注，
這是第一部35mm格式鏡頭，包刮了變焦：手動 /自動對焦，內置光學防抖，手動/自動光圈，手動 /伺服變焦。

One of the hits of PhotoPlus Expo was a surprise sneak preview of Sony’s amazing new zoom lens for their PMW-F3 Camera. Shown unofficially and “out of competition” to a few cinematographers, the new 18-252 attracted lots of attention on the show floor. With good reason. This is the first 35mm format zoom that I know of with many of the useful attributes of a smaller format camcorder zoom: manual/auto-focus, internal optical image stabilization, manual/auto iris, manual/servo zoom.

When would you use all these auto controls? Well, imagine doing some of the things we take for granted with small video cameras, only this is a real 35mm format zoom lens. Bouncing around in boat, following action from a helicopter, handheld on the tight end of the lens, shooting sports, car-to-car, bike-to-bike — optical image stabilization can be a huge help.

The lens is lightweight and tiny–yet covers an astounding range: 18mm on the wide end and 252mm on the tight. This is possible because it uses the F3′s FZ mount, which has a shallow flange focal depth of around 18 mm. This is much less than the 52mm depth we’re used to with PL mounts, and the lens has a lot less “heavy lifting” to do. Furthermore, this zoom takes advantage of the FZ mount’s electronic contacts to “talk” to the camera, just like many of the DSLR cameras we are using. (FZ is the name of the propriety Sony F3 mount.)

Sony’s new 18-252 mm zoom lens has been previously previewed as a prototype under glass, but this was the first time we could grab it and go. Which I did, with the F3 on its Chrosziel rig and SR-R1 Recorder nicely balanced aft. Skeptical at first, I was amazed how the image stabilization was able to smooth out my deliberate jumps for joy shooting handheld all the way out at 252 mm. Even the auto focus glided smoothly from one point to another.
Could this be the first 35mm motion picture point and shoot? Perhaps. More to be revealed tomorrow…
