I've been a lurker of the forum by finding results in Google on the searches I've done about gear I want. Here is my story.
I have a 40d which I bought at the release and 24-105mm 4L IS, 50mm 1.4, 100mm 2.8 macro and wanted to upgrade to FF. I am also going on my first photography tour in May and will visit a lot of amazing locations like the Grand Canyon and many national parks in the area. I want to be able to take the best possible pictures as possible. Hence my interest in purchasing a 5D Mark III. I made a mistake of purchasing 24-105mm 4L only a few weeks ago before I made my mind about buying the III over II. I would have saved $300 if I purchased III with the lens bundle. Oh well...
Since its a one in a lifetime experience for me I am trying to maximize picture quality in every way possible. To supplement wide shots I am also borrowing 17-40mm 4L from a friend. I will be carrying 2 lenses with 58mm filter size and 2 with 77mm filter size. I will be buying new filters to use on this trip and beyond. For protection I will purchase B+W UV Haze MRC 010M which are solid filters from my previous B+W experience. Now here comes the fun part. I recently read up on Singh Ray filters and did some reading from the older posts of this forum. I was hoping that someone who has been using Singh Ray can give me some advice.
1) I am looking at Vari-N-Trio as a combo package which will give me a lot new tools to play around with and can help me achieve better results during my trip and beyond. I read about vignetting on FF bodies and about thin mount being slightly better. Is the only difference between thin / thick is the vignetting difference + loss of ability to stack more filters on thin version?
2) Vari-N-Trio is not offered for 58mm size and originally I was planning on buying at the minimum a B+W CPL which is $80+. From Singh Ray lineup I could go for LB Color Combo. Is there any variable ND filters for 58mm size? Is my only option to match VNT is to buy various ND filters and adjust each time?
3) I will need to buy a new tripod for the trip. My current Manfrotto setup is too heavy, I've carried it for a few hours yesterday and was tired. I did my research and saw notions that Gitzo is better on many levels. I was considering buying Gitzo Series 1 Traveler legs + head and they are both very expensive. Yesterday I was at the Botanical Gardens doing some macro work and was not happy with my current macro setup (big tripod that I have and Gorillapod. I did some searching and came across Redged RTA 320 macro tripod. It looks like I will be able to take better pictures with it, it is more versatile. As I watched videos about various Redged products I came to do more research about bigger tripods that they have. Redged has some extra features that Gitzo doesnt have - the way it folds for lower settings, quicker opening, teflon lubricant. What do you guys think about this company? From my research they are just getting distributed to US but have been around in Europe from 2010. Getting Redged over Gitzo can save me a few hundred dollars and can pay some of the filters.
4) Any other suggestions or advice?
