I thought mannfrotto was the cheaper option
You can only have two of these three things when picking out a tripod.
Sturdy
Lightweight
Inexpensive
now pick two
No truer words on this forum ever!
Your camera has a reflex mirror. That's a moving part. Just prior to an exposure that mirror is in the light path and must be moved out of the light path. How long are you willing to wait for that? Most photographers prefer as short a delay as possible between the time they press the release and the actual opening of the shutter. Therefore the mirror is moved quickly out of the way with considerable force. It doesn't weigh a lot, but it's moved very fast and try as hard as they may, the engineers must in the end compromise between speed and some amount of shock as the mirror slams into the top of the camera. Your camera may be able to lock up the mirror before you release the shutter -- works for landscapes -- tough for wildlife.
If you get a lightweight metal tripod and then extend a center post on that tripod, the whole thing will likely resonant and actually amplify the vibration from the mirror impact. I've demonstrated this effect many times.
How much should your tripod weigh? Weigh your camera and lens and multiply by 7 for a minimum tripod weight (recommendation per A. Adams when using a reflex camera).
For what it's worth: I've purchased 5 tripods over time. 4 Manfrotto tripods in the first ten years and one Gitzo in the last 25 years. Over the long haul the Manfrottos cost me more money. I'll never replace the Gitzo. Assuming I've got another 20 years of shooting left that'll be 45 years for 1 Gitzo versus 10 years for 4 Manfrottos.
