Still no reviews of either camera, but that’s no surprise.

The Canon EOS 40D came to market extremely fast though, I think Canon is trying to win back some market share before the monster Nikon D300 comes out.

The specs are awesome as from the first release.

The professional Nikon D ’single digit’ series of digital SLR’s started life back in June 1999 with the groundbreaking D1. Groundbreaking because it was the digital SLR which broke Kodak’s stranglehold on the digital SLR market and fundamentally brought prices down to a level which most professionals could afford (around the US$5,500 mark). Since then we have seen a steady progression of this line of cameras, while the core values of a high quality full size body with integrated grip have remained the line split into two halves, one targeted at high resolution photography the other high speed sports type photography (lower resolution but faster continuous shooting); the X and H suffixes. It’s been almost three years since Nikon introduced a completely new digital SLR with a new sensor (the D2X) and there has been much anticipation that Nikon’s next move would be a full-frame chip.

There are also some new high ISO shots released.

Universal Vibration Reduction (uVR)

The new D90 incorporates an optional feature called Universal Vibration Reduction (uVR). This turns all lenses into uVR lenses, and offers a 10-stop advantage.

This means a person using a 500mm lens, who would normally have to shoot at 1/500th of a second, can shoot at 2 seconds when uVR is enabled.

The new uVR system isn’t sensor based, and instead requires one of the three optional vertical battery grips (see below). In this case, the MB-D90a is required. This grip provides all the normal controls and extended battery life of a regular grip. It also holds 8 EN-EL4a batteries, along with a step-up transformer.

Memory card incompatibility solved

The D50 and D80 caused some controversy by moving Nikon’s consumer-orientated DSLR models away from CF cards. This lead many Nikon users to resort to unseemly and ungentlemanly language in the forums (expressly forbidden under the terms and conditions of the standard Nikon warranty).

In an effort to avoid such distasteful events this time around, and ensure everybody can enjoy a D90, Nikon now supports the following storage formats…

• SD
• CF
• XD
• Memory Stick
• 3.5 inch floppy
• 5.25 inch floppy
• 8 inch floppy (in MB-D90b only)
• CD/DVD (in MB-D90b only)
• High-speed paper tape to maintain compatibility with Colossus
• Punch cards

New built-in artistic-effect modes

In addition to the regular scene modes, Nikon have included several artistic-effect modes. You can apply these to your image in-camera. Modes include…

• Black and white mode
• 1960s-style fast-film grain mode
• Nikon long-banding effect mode
• Canon plastic skin mode
• KM7D high ISO smearing mode
• Sony Alpha 1.3-stop underexposure mode
• Point and shoot artefact mode
