Shure SM94

Shure SM94 microphone Review

The Shure SM94 is a unidirectional electret condenser microphone tailored to the instrument miking needs of professional musicians and sound engineers in both live performance and sound recording. Its smooth, flat frequency response is free of either a presence peak or a low-frequency rolloff, making it a perfect choice for all types of musical instruments.

The Shure SM94 is equally at home in sound reinforcement systems or in sound studios and motion picture/ TV scoring stages. When used with the optional wind-screen, the SM94 can be used by vocalists and speech-makers who desire a wide, flat response with minimum coloration.


- A sensitive mic with a wide, flat response ideal for live amplified and acoustic instruments.
- Extremely well-suited for reproduction of stringed instruments, woodwinds and cymbals
- AA battery or phantom power
- Internal shock mount
- Wide dynamic range
- Smooth, flat frequency response
- Uniform Cardioid condenser
- Frequency response: 40 to 16, 000 Hz

Pretty good

I'd call it the best camera for that price. I'd go for it.
FYI, Downsides are:
* Limited lens compatibility (no autofocus motor, so many Nikon lenses won't work)
* Autofocus is slow enough to be completely useless in live view mode (try it in a store)
* Video mode isn't up to par with Canon and friends. You get limited resolution, awkward frame rate, horrible audio (11kHz with low quality built-in microphone, and no microphone input, and the kit lens will give you lots of image stabilizer noise).
Stepping up, Canon 550D is an amazing camera (albeit without the pivot LCD)
