I tried that Optex Lens Last month for one wedding shoot. I love the quality & the sharpness of the lens. I end up returning it coz I miss some important features I mostly use like low shutter speed & AE lock feature. Also Canon is coming with a Manual Lens for XL-1, I'll wait for that. By the way I bought the Cam as used, Body only, no Lens. If you're not using your Original Lens or planning to buy the Optex. I'll be interested with it for a good price,(posted 8933 days ago)
