<p>Thank you all for your invaluable responses and pictures. Though I am not active participant on this forum, wonderful people like you have always helped me with my questions. Yesterday I visited local camera store and tried all lenses.<br>
As most of you suggested, EF 85 1.8 was an easy decision and I got it. <br>
EF 70-200 F2.8 IS was ruled out due to size and weight. <br>
Among EF 70-200 F4L IS and EF 70-300L IS, I finally took EF 70-300L IS. It is little bit more weight in my camera bag and reduces some more weight on my wallet, but 100 mm extra focal length may give me some more flexibility especially because I do not like extenders. As all of my travel is with family, kids and friends, I like to have simple, minimum and quick set up. <br>
Thank you for pointing out about wider lenses. I will certainly look into this may be little bit later. As some of you suggested, I have dropped idea about Macro as I realized that I only shoot it occasionally and this will be unnecessary expense and I would rather spend that money on wider lens. <br>
Btw, 5D mark III seems a big change for me from my earlier 40D and I am starting to learn it. <br>
On David's suggestion on software, I do shoot RAW, and have Lightroom 4. However, most of the time, due to time constraint I can only do quick exposure adjustment. I was unaware of DxO optics pro and just looked at internet and seems amazing companion with LR. I will definitely consider it. </p>
