Im­age Sta­bi­liza­tion (IS)

Consumer Voice - - Comparative Product Test -

Nearly all cam­eras, in­clud­ing many with pow­er­ful lenses, now come with an im­age sta­bi­lizer, a de­vice that com­pen­sates for hand­held cam­era shake. Of­ten, the IS de­vice lets you shoot with a slower shut­ter speed than you oth­er­wise could with­out pro­duc­ing blur due to hand shake (al­though it won't com­pen­sate for a sub­ject's mo­tion). Op­ti­cal (in the lens) and me­chan­i­cal (in the cam­era body) im­age sta­bi­liz­ers are the best types to use, al­though some cam­eras in­clude sim­u­lated sta­bi­liza­tion.

In dig­i­tal SLRs, some brands in­clude me­chan­i­cal sta­bi­liz­ers, which can use IS with ev­ery lens. How­ever, some SLR brands only in­clude op­ti­cal IS in tele­photo or long zoom lenses, the ones that need it most. The op­ti­cal-based IS gen­er­ally pro­duces bet­ter re­sults than me­chan­i­cal-based IS. Note that you will not find IS on ev­ery lens as it is not built into the cam­era body. If your cam­era has an op­ti­cal zoom greater than 3x, then im­age sta­bi­liza­tion is a must fea­ture.
