Probably not for reliable long exposures with a DSLR and superzoom. The main issue isn’t just the rated weight limit: Gorillapods are more sensitive to balance than a conventional tripod, and longer lenses shift the center of gravity forward. Several users report the SLR-Zoom becoming unstable or finicky once the camera is off-level or the lens extends much beyond the body.

It can work in a pinch, and it’s still better than hand-holding, but for 5-30 second exposures you should expect vibration and setup sensitivity. If you do use one, a remote release or long self-timer is important to avoid shake.

For a DSLR with a long zoom, the safer conclusion is that the SLR-Zoom is not the best choice if stability is your priority. A heavier-duty model such as the Gorillapod Focus, or a more traditional travel tripod, would be a better fit.
