Hi all. I've got that New Lens feeling, so I've been thinking about getting a 50mm lens for my Canon 5D. In college 20 years ago we only had 50mm lenses, and I've been feeling nostalgic. I've been thinking of a project, and I want to shoot my kids' favorite toys very close up with a very tight depth of field. As such the fixed focal length will allow for the widest aperature. I want to get in even a little tighter than for this shot. I plan on making very large prints for their rooms from these images. So there are three lenses that I'm considering: Canon EF 50mm f/2.5 Compact Macro (about $230) Lens Construction: 9 elements in 8 groups Closest Focal Distance: 23 cm/0.8 foot Canon EF 50mm f/1.4 USM (about $310) Lens Construction: 7 elements in 6 groups Closest Focal Distance: 45 cm/1.5 feet Canon EF 50mm f/1.8 II (about $75) Lens Construction: 6 elements in 5 groups Closest Focal Distance: 45 cm/1.5 feet So, any relevant advice would be appreciated. Which lens should I consider? Am I missing a 3rd-party lens that I'm unaware of? Do I even need a lens like this? Your thoughts and comments would be appreciated.
