Evening,
Out on the front page of the forum, there are a couple tripod reviews that can possibly be of help.
I really don't have an opinion on either. The Sirui is a very well known and respected brand. There are a lot of very good tripods around. I tend to focus more on the head and less on the legs - but that is just me.
Here is a bit of personal experience - in story form....
- About 8 years ago when I started in digital with my K100D (that I still have), I found a cheap tripod on ebay. I won the auction for 11 cents plus $7 shipping. It was a combination of aluminum and plastic construction. The K100 is very light along with the kit lens. It was not the best, but it was tremendous for learning what I liked and hated. It was suitable for the equipment I had and what I was using it for. I like flip locks on the legs - hate twist locks. I hate the 3D video head. It folded up very small and fit into my airline carry-on luggage. After a couple of years it fell apart.
- About this time, I upgraded to a K20 and needed a new tripod. It had to fit into my carry-on luggage. I decided on the Benro Travel Angel. The ball head that came with it was useless (Benro has since gotten serious about their ball heads). I went shopping for ball heads on the internet. After several weeks of research, I decided on the Acratech GP. Now this little gem runs $400 - just for the ball head. Its lightweight, with an open architecture that does not collect dirt or grit - great for backpacking. I also do a lot of panoramas - and this specific model has the option of mounting inverted so that the turntable is ABOVE the ball head. Why is this important? Well, when you rotate during your pano from frame to frame, if the turntable is under the ball head you will not capture a level panorama unless your tripod is perfectly leveled via the legs (sometimes difficult to do)d (and to correct for it you will need to crop - thus making your pano that much more skinny). I choose to level the tripod via the ball head - and with the turntable above the ball, this is a quick 5 second operation. Now, is there a cheaper option to do this? Yes - now you can purchase a standalone turntable and put it between the ball head and camera plate. It took me several weeks of additional thinking about the Acratech GP - did I really want to spend the money? Finally, I just bought it - and have never regretted it. It is my single most used item. Upon its arrival - my wife told me that this had better be a jewel encrusted astronomical instrument. It looks so different - that I actually survived the purchase. Here are a couple of videos that explains the inversion and the level panning better.... Also, they show some various features that may not be apparent.
- The Benro Travel Angle at the time only came with twist leg locks - which I have come to dislike (I think that you now have an option between twist and flip). But, for traveling and fitting in the luggage - it really works very well. The downside is its light weight. [On a side note here - there are two main tripod styles - 3 leg section and 4 leg sections. The more the leg sections the smaller it folds for traveling, but also the more shake that can be induced into the tripod system. Its a trade off.] So, I decided to supplement it with a heavier tripod, and move the GP ball head between the two. I wanted to keep this tripod in the truck for shooting. I also wanted to keep the cost down and decided that I should be able to find a used good "beater" (I really did not care what it looked like) tripod for around $100 +/-. After about 6 months of looking periodically on Craigslist, I found one locally - a Manfrotto/Bogen 3001BD. A older heavy tripod, large 3 section unit - flip leg locks for my price (and no shipping charges). It also came with a Manfrotto 486RC2 ball head. This is a single lever (no friction control) large heavy ball head. The single lever with out friction control is good for a spotting scope, but not for a camera. Also the RC2 plate system had a safety capture latch that I could only work with 3 hands - one holding the camera, one pulling the safety latch while the third hand was working the capture latch while the safety was pulled out. Not workable for me, so I sold it (the 486RC2 head) and reduced my overall cost (to almost 0 - free is good). The tripod works great - as expected. Its my main tripod, however - its too large to fit into my luggage (and too heavy for traveling), so I really have the best combination for what I do.
- Lately, I have been doing some astrophotography. I will say the one drawback to a ball head - even the GP ball head, is that for fine positioning you loosen the knob and you have all 3 axis in play. So, to aim the camera at a particular place in the sky and have some fine positioning (one axis at a time) - while hating 3D video heads, I went back to craigslist looking for a geared head - a Manfrotto 410. It took almost a year but I found one about 8 weeks ago for less than a third of its new price. Even though Manfrotto calls the 410 a junior geared head, its massive, large and heavy. It works well, but something that I would not want to travel with. I use the 410 about 10-15% of the time and the GP the other 85% of the time. Again, this combination is working out for me - personal preference.
I see you are located in France. I am guessing that you have a Craigslist over there or something similar. To start out, I have found that lots of folks go out and buy tripods, use them once or twice, and then several years later, after cleaning out their closets - sell them. You might not find exactly what you are looking for (brand and model), but it could be good enough for the right price. The key is, understanding what you want and how you want to use it.
There are three items - the tripod itself, the head (ball head, geared head, 3D video head), along with a quick release mechanism that allows you to mount and dismount the camera relatively quickly. This consists of a clamp on the head and a plate that attaches to the base of the camera. The plate fits into the clamp which then locks it into position. Yup there are a few "standard" clamp/plate systems in use. Manfrotto has one with the most popular being the ArcaSwiss system.
Anyway - that is my quick overview.
