camera questionPosted By jim renard |
Hi wondering what camera I should purchase shooting with a 61cm rc f7.5. Would a stl camera with a kodak 11000 chip be okay seeing approx 2arc sec. Or a camera with 9000 chip or 16803 chip. Like to know a cost versus performance. and ease of use. Any comments will be helpful. Also has a 5 inch field flattener so field not a problem
