Canon Vixia HF S21 Camcorder


Canon's 2010 HF S series of AVCHD camcorders consists of three models that, as usual, differ by memory configuration and the aforementioned viewfinder. Their key specs remain the same as their predecessors', with the same optics and sensor, but they...

Excellent set of manual features; dual SDHC slots; generally well-designed interface

Poorly designed touch-screen menu system; short battery life; defaults to low-quality video mode; doesn't support SDXC; relatively expensive

Though they're an excellent trio of camcorders, the Vixia HF S21, HF S20, and HF S200 are significantly more expensive than their respective competitors, especially since the S20 and S200 lack electronic viewfinders. If you can forgo some of the...

Canon Vixia HF S21 Camcorder Review


The Vixia HF S21 ($1399 MSRP) is the new-and-improved flagship camcorder from Canon. With 64GB of internal flash memory, two SD/SDHC memory card slots, and a brand new touchscreen LCD, Canon appears to have put in quite an effort in revamping last...

While Canon spent a good deal of effort improving the features for the HF S21, it didn't do much (if anything) to improve the video performance of the camcorder. In our testing, the HF S21 actually did worse with color accuracy than last year's HF S11,...

Canon Vixia HF S21 First Impressions Camcorder Review


The HF S21 is Canon's flagship camcorder for 2010. The camcorder has the same lens and sensor as last year's HF S series from Canon, but this new model includes an impressive 3.5-inch LCD touchscreen, as well as a handy electronic viewfinder. The HF...

We're mostly supportive of the updates made by Canon on the HF S21. The new, 3.5-inch LCD touchscreen is a wonder to behold, but it did have some of the same problems that plague most camcorder touchscreens. It didn't offer precise control, and we...

Canon LEGRIA HF S21 camcorder review


Top notch image quality but at a steep learning curve

You can connect the LEGRIA HF S21 to a TV using composite or component output, or for maximum quality you can use the mini HDMI terminal to connect it to a HD TV. A USB port provides computer connectivity. The LEGRIA HF S21 allows you to convert AVCHD...

Canon VIXIA HF S21 HD Camcorder Review


Native 24p ; Component and HDMI output ; Ultra-crisp focus ; Effortless video transfer to computer

Grain in low light ; Colors are a bit dull

This camera makes a great little tool for video creators of all levels. Handy, compact and takes great HD footage. A definite buy.

Canon HF S21


Features have improved over last year's model, but performance has stagnated

Excellent sharpness; Good manual controls

Color and noise results subpar; Low-light performance equally rocky

Canon VIXIA HF S21


The Canon VIXIA HF S21 offers the best of all the features we looked for combined. The 64GB memory, though not at the top of the pack, combined with the dual memory-card slots means that this camera has more memory than more than half the products...

This HDV camcorder has two SD card slots for extra memory capability

The still camera resolution is 8MP, which is lower quality than some digital cameras on the market

The Canon VIXIA HF S21 has a good zoom, flash memory and SD memory card options, and while none of them are amazing, combined they make the product great overall.

Canon LEGRIA HF S21 review


Full HD camcorder with massive 64GB storage

Movie and stills quality ; HD-to-SD file conversion ; Easy YouTube upload ; Loads of connectivity ; Storage options

Troublesome touchscreen ; Small colour viewfinder ; Considerable investment

The LEGRIA HF S21 is not for the frivolous. It's an expensive and heavily specified camcorder and one that requires time and dedication to create the best results. If that appeals to you then this is one of the most comprehensive and compelling HD...

Canon Legria HF S21 review


The Canon Legria HF S21 sets new standards for home-video image quality. The camcorder is large, expensive and complicated to use, but if you're after the best, you're unlikely to hold any of these factors against it.

Stunning picture quality ; Expert-level manual controls ; Plenty of storage options ; Large, high-resolution screen plus viewfinder

Slightly unresponsive touchscreen ; It's a shame there's no 50fps progressive mode ; No HDMI cable included

For enthusiasts who really want to push the limits of what you can achieve with a home video device, it probably comes down to a choice between this and the aforementioned Panasonic HDC-TM700. Both have their pros and cons but, for our money, the HF...
