Shutter lag
The D70 proved to be an extremely fast camera, Nikon has clearly taken large steps to ensure that in use this camera feels and responds just like a film SLR, and they've achieved that. Startup delay is nonexistent with the camera ready to shoot at the instant the power switch is turned to On. Shutter release lag simply isn't there, the camera responds to your slightest input and the shutter just opens when you depress the button, as you would expect.
Thanks to newly a designed buffering system, extremely fast image processing and blistering Compact Flash interface (with the right CF cards) storage times are so short to be of almost no consequence. The D70 literally wipes the floor with the competition for continuous shooting capability, indeed you'll need to spend significantly more to find a digital SLR which is any faster. Kudos Nikon, the D70 sets a new benchmark at its price point.

D70 review---------------------
No external flash sync but you can buy one for 17 bucks. Right now I'm using a bounce flash aimed at the ceiling to trigger the slave on my studio unit which is the same thing I had to do with my older N60 film camera. Eventually I plan on buying a Pocket Wizard radio slave.
