OIS

Purely as an aside, I think it’s very unfortunate that DSLRs don’t come with an integrated OIS module. It’s particularly surprising when you realize that an increasing number of prosumer cameras tout this as a must-have feature.

Oh. Right. OIS stands for Optical Image Stabilization. Essentially it allows you to shoot at far lower shutter speeds than expected. It’s secret lies in the processing/post-processing performed by the on-board imaging sensor, which compensates for your shaky hands.

Since I have the shakiest hands of all, this feature would be a God-send.

Unfortunately, the two most well-known DSLR manufacturers have chosen to integrate OIS into their lenses – Nikon with their VR (Vibration Reduction) and Canon with their IS (Image Stabilization). Only K-M introduced on-body image stabilization with their Maxxum 7-D. I think a better approach would be the inclusion of an on-board OIS module that would compensate extremely well at shorter focal lengths while reserving lens side image stabilization for longer focal lengths. The imaging sensor in the camera can detect the presence of lens-based VR elements and enable its on-board module appropriately.

Is it more expensive?

Yes.

But it allows for OIS in shorter focal lengths without having to create VR versions of the lenses.
