As a texture artist, I'm constantly searching for new material to photograph for use in my 3D work. Lately however, I've been growing more frustrated with my old compact 5MP Leica due to the perspective camera distortion it introduces with every brick wall and fence I photograph. Consequently, a lot of time is spent correcting this in Photoshop. I'm now in the market for a better solution that will help to either eliminate or drastically reduce the effect of lens distortion. Budget is around $600 or so. Any recommendations?
