I've been an Olympus shooter since I bought an OM-1 back in 1977. I currently shoot with an E510. For a couple of reasons, I have decided to venture into Nikon territory. I've always had a high opinion of Nikon cameras and Nikkor glass. I have an opportunity to pick up both a D90 and a D300 for reasonable prices. I can't afford both, so I have to decide on one. The D300 is more expensive, but not out of my budget. I'm looking for suggestions on which I should get. I know a lot of it is very subjective, so I'd appreciate hearing pros and cons of each. I mostly shoot models and portraits. I'm also planning to branch out into small weddings and events. Thanks in advance for your help.
