I am new to photography and do not know which tripod to purchase. I've only gone out a couple of times to the flower conservatory and park to take pictures and can see myself using a tripod for some landscape shots. I saw this Slik Sprint Pro II with Pan Head and the reviews for the ball head version is decent. I think I prefer the pan head to use to shoot smoother video when moving from side to side. The size seems compact enough to strap on to my backpack, but some have said the diameter of the legs make this unstable when the legs are fully extended. I looked at this other Slik Pro 700DX tripod, but think it's too heavy to travel and might be overkill for a beginner. Any recommendations on what I should purchase? My budget is below $150.
