I own the Redged TSC-428G - Special Edition - Ultimate Travel tripod
Two legs can be turned 380 degrees when you want to screw them more tight. That bothers me really. For a long time I want to either buy a Gitzo (I own a Gitzo monopod GM5561T) or a RRS. All the time some other gear gets in between....priority, priority priority  ;D

The center column is not so much for getting up to your perfectly comfortable viewing height, but for making a convenient, quick up or down adjustment while "in the flow."

Lots of tripods sold with, and not quite as many sold without, from a quick survey of online offerings and my good old B&H paper catalog.

Sad how it's so hard to find a photography store in the USA to try things.


True.
I can try in the shop but not renting. Meaning bring some gear to the shop and have some form trying out (better than nothing)

No centre column leaves me with tripod height of 157cm. With ballhead & 5D MKIII with grip I reach 182cm. That works...but is the maximum. When placing the camera via tripod-ring of, for example, 70-200 or 70-300 it is a little less. I am 187cm (6.1 ft)

I have a lot of tripods hanging around- 35 years old.  It really depends on your need at the moment- are you hiking miles?  Shooting wide or telephoto?  Calm winds or in a tornado?  Do you shoot just stills or video?
My most stable tripod is an old solid aluminum beast with a adjustable locking center spreader, and geared center column. It's heavy and it's stable.  Short of mounting the camera on a 100. lb. block of concrete, any tripod needs time to dampen vibration.  My video tripod for the 20 pound camera is the best for stability but worst to carry around.  I use a remote trigger while tripod mounted, unless I'm constantly shooting a moving subject.
I mainly use the center column when shooting Astro stuff.  Also, if you are tall, you can raise the center column  to a more comfortable height.  It's all a trade off.
I use live view most of the time.  Zoomed in all the way, you know exactly when the vibration has stopped.
Shooting in live view is noticeably better for sharpness for short exposure times.
Then there is my $20 tripod.  We won't go there ;)


Funny thing that so many are sold with a centre column...or?
True, I am 187cm (6.1 ft) Difficult to find the right tripod and then fumble with those legs. Why aren't there distance markers (every 1cm) on the legs?

I wonder what is better (or preferred?) centre column yes or no? What is your opinion or experience?

I currently use a tripod with centre column. Advantage is that it is easy for me to adjust height - if needed. Sometimes I use it from a sitposition (walkstool) and pick things up to move to a different location (with different level underground) So very easy (and fast) I can adjust my camera height by adjusting the centre column. It is just one ring to turn instead of 3 (from the legs)
However sometimes I feel that, while centre column is moved up,  the whole thing is less stable. Don't know if it really is or just my feeling.
I am asking because I am looking for a new tripod and wonder if to buy with or without the centre column. I guess I could buy with and remove it or not use it.... :-\

You usually use a tripod to stabilize your camera. 
 
Its been shown over and over again that you will lose stability.  This means that long exposures will be fuzzy.  I did not know how bad it was when I first started, and always got blurred photos when using long lenses.  Later, I figured it out.
 
Here are three articles on tests run a few years back with a high end Gitzo Tripod.  The results are ugly.  Read all three articles, since he refines the test as he goes, and discovers its worse than thought.

Many tripods come with center columns, but keep them down for long exposures.


Thanks for pointing me to those 3 articles. Very informative.
I see I have so much to learn yet.

Centre column is useful to have. If you're using the tripod to hold the camera rather than critically support it at lower speeds, then use it for convenience.


I want to use it more to explore lower speeds. Until now mainly to hold the camera. Thanks

It's not a feeling, it's physics.  Raising the center column reduces stability. 

Some load testing I did a while back is relevant...

http://www.canonrumors.com/forum/index.php?topic=20499.msg392683#msg392683

Vibration damping time with 1D X + 70-300L:

  • RRS TVC-33 + BH-55 LR (no center column):  ~1 s
  • RRS TQC-14 + BH-30 LR (center column down):  ~2 s
  • RRS TQC-14 + BH-30 LR (center column raised):  ~4 s
The first set up is among the most stable support rigs available.  The second set up is RRS' travel combo, but still quite stable, relatively speaking (the TQC-14 is approximately equivalent to a Gitzo 2-series).


Thanks for this information. Very useful

it´s simple physics....

Ha, I knew it....I will never win the Nobel prize for physics ... ;D

Lenses / Re: Review: Canon EF 16-35mm f/4L IS
« on: July 01, 2014, 06:09:12 AM »
I wonder if Canon are re-jigging their wide zoom range. Maybe from a 17-40L f4 and 16-35 f2.8 II L range to a 16-35mm f4 LIS and 12-24mm f2.8 ranges?
If so, I can see both being added to my lens bag.

O yes, this is my guess too. For me, for the moment, 16-35 f/4 IS is enough....for now....

I really enjoy my 16-35 f/4 IS but not yet enough (lack of time). I hope to go out in the weekend and do some landscape shooting  :)

Canon General / Re: EOS 1D X + 300 f/2.8 IS II + DxO = Awesome
« on: June 30, 2014, 01:03:04 AM »
Here's a 100% crop of a great horned owl photo taken 9 minutes before sunrise this morning.  I got better shots of the owl, but this was the first shot and it was a mere silhouette to my eyes.  The bird took off right after this shot to a nearby tree and I didn't think I had even focused on the bird until I got home and downloaded my photos.  I couldn't believe it!

f/2.8 1/160s, ISO 4000, EV+1, pushed ~0.25 stop in post, DxO Prime:

Wonderful capture!
I still dream of going out early and running into such wonderful subject.

Does DxO do anything special when it exports to LR? (I don't use LR so don't know what this is about). I just export DxO as a jpeg and then open with PS.

As far as I know - no (EDIT: except maybe applying some default LR5 profile settings if you have set so)
After you export to LR5, it opens automatically LR5 ready to do some adjustment in LR5
