Have tested in direct comparison with my older CX505 (25i), the new Sony HDR-CX690. And one thing is said in advance. A qualitative picture quality improvement is barely noticeable from my subjective observation. The 50p frame photography carries nuances to produce less motion blur in horizontal and vertical panning. Here you have but to look very closely in order to recognize the so. A disadvantage is the much larger amount of data generated at 50p setting. In the measured values 50p recording produces greater by about 1 third volume of data. In Review: 25i produced with the same recording length 295MB the 50P brings it here to 450MB. The benefits of the CX690 are in my opinion the integrated wide-angle. Here you had to work with the predecessor with a screwed-on converter. Disadvantage is again the decreased telephoto range as opposed to its predecessor. The various settings when shooting, such as custom white balance or adjust the ISO values (one previously knew only from photographs) may result in improved Filmufnahmen nuances in specific situations quite well. The possibility now also use SDHC card in addition to the usual Sony Memory Stick, I see it as quite positive. Would certainly have been even more beautiful if you could use both in parallel Hinblich on prolonged storage overarching recording. However, this is not possible. The integrated USB cable with the convenient insertion into the wrist strap makes it possible to store when traveling without entrainment of the power supply and is visually and structurally succeeded. The photographs appear in my opinion stronger. Here the various individual settings, such as the ISO values, among others afford even greater services through increased Wide range has the camera in practice a greater range of applications in terms of Innraumaufnahmen. A small disappointment is the slow motion function for me and indeed quite simply because of the reduced image quality especially with this function. Win 7 shows me here (1440x1080 at 25p) although generally the 50p (1920x1080) recording is set. The slow motion itself is fluid and as one desires a slow motion. However, the slow-motion shots just do not have the brilliance of mind at the same shooting situation as no slow motion. On the subject of sound, I can not anything earth-shattering to report new. Even with the CX690, the 5.1 audio recording is out strongly affected by wind action remains. The altered structural arrangement of Microphons in the CX690 (CX700) can enter any pluses to its predecessor, in my view, unfortunately, here. Conclusion: If you can spend just not 2-3 hundred euros more should he no HD camera has quite pull the Sony CX505 Sony HDR-CX520 predecessor models and in consideration.
