This is a medium weight tripod that punches above its weight. It is sturdy enough for a medium weight dslr or 35mm film camera with motor drive. However, using it with a very long lens could be stretching it a bit. It is quite ok as a luggable, lightweight, portable 'scope tripod for field use. It is well designed and very well manufactured, and takes quite a lot of punishment in the field.
The use of thumb-screws for leg adjustment may not suit everyone, and it is wise to double check these for tightness before mounting a camera. The angle of each leg is individually adjustable, to give low level capability or compensate for very uneven ground. Also, the centre stem can be inverted. There are a wide variety of heads that can be fitted, and the platform has locking screws that prevent a Manfrotto head from twisting and coming loose.
Overall, this is a very good tripod in my view, and complements other much heavier and more complex tripods. It is very good value for money - there are cheaper tripods, but Manfrottos last and can be 'systemised' with alternative heads and QR plates, etc. My other (heavier) classic 190 is over 12 years old; it is a bit battered, but still performs like new.
