OK so we had a little Windfall of about $3,000.00 Currently I have a Canon 40D Lenses covering from 17mm to 300mm Canon 17-40 L Canon 70-300 IS USM <----EDIT: Note change - I have the 70-300 IS Tamron 180SP ( Macro ) Speedlite 580 I was looking at the Canon 50D ( $1200 ) and the 5D ( $2600 ) After reading up on Pixel Density and the pitfalls of high density sensors I am not so sure that a 15 MP APS sensor or a 21 MP Full Frame sensor is the way to go. The 10MP 40D is rated better than the 15MP 50D. That being said I am beginning to look in other directions. Maybe it's time to consider jumping over to Nikon??? So the question is, in the situation as described about .... what would you recommend doing, and why??? One Nikon I looked at was the D300 but I am not leaning in any specific directon. Work includes .... Portrait/Model and Product Photography ( Macro is needed here ) Thanks for the ideas !!!!!!!
