I don't print my pictures, only post them onto Facebook and Flickr, paid jobs are very rare.
But I'd love to get a full frame camera. I tried a friend's 5DII today, and I think my L glass really performed better, and I really loved the images. I also like to take travel pictures and think the 24-105 is the best Canon travel lens(on a full frame camera).
Over here, used 5DIIs cost slightly less than half of a new 5DIII, and I can afford one by the end of this year(I can sell off my crop lenses to get used 24-105 and 17-40). I'll still keep my 7D for nature and macro shots.
Or should I continue to save up for a 5DIII instead? There is no hurry to get a full frame camera anyway, but the 5DII's autofocus is sluggish compared to the 7D. But I can get some nice glass like the 35 1.4 or 85 1.2 with the difference.
