Camcorders: HD vs. SD optical zoom?

Q. I'm looking into purchasing a digital camcorder and I noticed that the optical zoom on standard def camcorders goes up to 40x, whereas high def camcorders only have 10x optical zoom. Why is this?

note: I'm aware that they also have the digital zoom, but there is a generally a loss in picture quality when digital zoom is used.

A. Good question! Many retailers will try to tell you that the higher the optical zoom, the better. This is a misconception. On the contrary, when you zoom in 30X or 40X, your picture will become uncontrollably shaky, and the picture quality will be worse quality at 40X (it is not as noticeable with optical zoom, but it is still there). Sure, optical zoom is important, but in most cases, you will probably not need more than 10X or 12X. It is true that many cheap consumer camcorders have optical zooms at 30 or 40X, but most professional camcorders have optical zooms of 12X! In conclusion, do not let optical zoom turn away from a camcorder you like. Hope that helps!


Beginner HD Camcorder?
Q. I want to purchase a camcorder that records in HD. On Youtube 1080p if possible. (1920x1080 Fulll HD Video). I've looked at models such as Sony HDR-CX190 and Sony HDR-CX110. Those run to $250-500 and thats a bit out of my price range. Anything I can get that I can handle from a firm 150$-200$? I just want a camcorder that records in full HD quality, has a fairly good optical zoom (25x), and HDMI output. Please help!

A. Hi Richard:

You need to get more realistic with your budget or else lower your expectations of what you plan on getting as far as your "feature list". The first to go away will be the 25x optical zoom for most cameras in your price range. (Unless you plan on buying "used" gear.)

TV stations spend THOUSANDS of dollars to upgrade their Standard Def TV cameras, lenses, and recorders to handle "HD". And average consumers like you expect "NFL Today" quality on your home TV or YouTube with something under-$200 from WalMart or BestBuy.

It ain't gonna happen, young sport.

You'll find decent optics (glass not plastic lenses), an HDMI output connector, full-HD and image stabilization, but only 4x digital zoom (no true-optical zoom) with most of the Kodak PlaySport and PlayTouch model camcorders, all of which are under-$200 (and some of the $179 models can be found for $79 on sale). But Kodak has stopped making all of its digital cameras and camcorders, so supplies of the PlaySport/Touch series are becoming scarce.

To find decent optical zoom on an under-$200 HD camcorder (without taking your chances on a used "eBay bargain") you'll have to compromise elsewhere in your list: the new Samsung F80SN camcorder has a whopping 52x Schneider zoom lens (and "fast" at F1.8), but only records in 720HD, but on YouTube you wouldn't be able to tell the difference in resolution. It also has HDMI output, and utilizes 1080p up-scaling when displaying photos or playing your 720p video, so you'l get great viewing quality for the money.

The only other cheap line I'd recommend is the Sanyo Xacti pistol grip style camcorders or the palm-sized Sanyo camcorders, which have 10x or more optical zoom, HDMI, and full-HD recording. Panasonic just recently acquired Sanyo, and I haven't kept up with what models are still "Sanyo" branded and which ones now appear with the Panasonic name instead. The Sanyo Xacti VPC-CA100 was one of the better pistol grip models, and you might still find it available online. This Sanyo, like most of the Kodaks, is waterproof in case you drop it in the pool (or sink/toilet) or take it to the beach.

hope this helps,
--Dennis C.
