I have an EOS 1V that no longer works. With that camera, I collected these lenses: 16-35 f2.8L 24-70 f2.8L 70-200 f2.8L 180 Macro f3.5L All of my gear was purchased around 2002. I have not shot much in the last several years due to a failing camera and the dislike for the film/slide workflow after local stores stopped processing slide film. I really miss getting outdoors and shooting. My interests are nature, landscape, and macro photography. I will also be capturing my 3 year old grandson, as it's just hard to resist. I feel that a full frame sensor body is where I want to be to maintain my wide angle zoom. That leaves me the 5d II, 5d III, and the new 6d. Any thoughts or recommendations on these bodies? Will my lenses still be relevent with the new bodies? Your insight is greatly appreciated!
