Camcorder - optical zoom?

Q. I have searched Google but I would still like someone to confirm that the bigger the optical zoom the better, i.e. 40x optical zoom is better than 10x optical zoom.
I was out with my parents today looking at camcorders and the Sony staff member told us that the less the better. Actually, what I think he said was the less optical zoom the better the quality. (Maybe all three of us heard him wrong and he was talking about digital zoom) Does having, say, a 25x rather than a 40x have any advantage in any way?

So, optical zoom is better... the bigger the number? The DCR-SR35E costs �399, has 30 GB, 40x optical zoom. The DCR-SR75E costs �599, has 60 GB, 25x optical zoom. The still pictures have a difference of 200,000 pixels. I'm just wondering why the more expensive one has an inferior optical zoom.

A. Looks like you are having fun out there :)

DCR-SR75E with the 25x optical zoom is the winning choice, due to its lens system.

Do not be tempted by the lower price and the 40x zoom on the other one. Being honest, you will never need the 40x zoom - and when you Do zoom @ 40x, I doubt it will be anything satisfactory.

In real life conditions, we hardly zoom over 3x for landscape and 8x for portraiture.

If your budget is right, go there again with your parents and get the DCR-SR75E !

p.s - you should also try out a few Canon camcorders if they are available there :)


Are there any digital cameras and/or camcorders offering optical zoom in video mode?
Q. Hi, anybody knows if there are any digital cameras and/or camcorders offering optical zoom in video mode?

All I've ever had are camcorders and digital cameras that feature only digital zoom when recording video, and the quality of that zooming is lousy; you see the quality difference immediately, when playing back the videos.

If anybody knows, I'd appreciate some suggestions, preferably budget cameras, USB compatible, so I can transfer to my PC.

Thanks a lot in advance for your suggestions.

A. All "real" camcorders have optical zoom and digital zoom.

It sounds like you are using a very low-end flip-like or toy camcorder or a camera that is primarily used for taking stills (and happens to have a "video" feature).

MiniDV tape based camcorders provide the best available video quality - but they use firewire (not USB) to transfer video to your computer. USB is only used for transferring stills from the camcorder's memory card or webstreaming (of the camcorder has either of these features). Adding a firewire port is typically not difficult - and it is pretty cheap.
Canon ZR800, ZR950, Sony DCR-HC52, HC62 and Panasonic PV-GS320 are good, entry-level, examples.

Hard drive and flash based camcorders compress their video a lot, but the quality isn't too bad... Video is transferred using USB. Sony DCR-SR45 and Canon FS10 are examples. They typically cost more than miniDV, but that does not mean the video quality is better - compression of the video information translates into lost data and can result in reduced video quality.

In any case, when you shop for a camcorder, do not use digital zoom as a feature comparison item - because when you bring the camcorder home, your first step is to turn digital zoom off. Use only Optical zoom.

Other things to look for in a good camcorder:
Mic-in jack (optional, but very useful)
Some sort of audio manual control (again, optional, but if you think you might be recording loud audio, like bands, this will be a requirement).

DO NOT BUY A DVD BASED CAMCORDER. Their video is terrible - especially for editing or uploading to the web. The discs are a pain and can be unreliable (resulting in list video).
