This is the cheapest reasonable setup I could conjure up. The prices are from eBay. You really only need the body, lens and memory card.
- Canon 10D body – $150 (or a Nikon D1)
- Battery – $15 ($30 for Nikon)
- Tamron 19-35mm f/3.5-4.5 lens – $60 (Tamron 28-80mm – $20)
- CF memory card – $12
- Vivitar 285HV flash – $50
- 5′ PC to Vivitar cord – $18
- Canon EF 50mm f/1.8 lens – $90
- Rokinon 8mm f/3.5 fisheye lens – $250
I didn’t look for very long, and I’m sure there are cheaper products, but this is decent quality for a very low price.
