I've recently been blessed with the great news that my wife and I are expecting our first child. After a few days our talks migrated a bit towards video and pictures. My current setup is:
60D (recent upgrade from the XSi)
15-85 (recent upgrade from the 18-55 that came bundled with the XSi - and sold with it as well)
55-250 (also bundled with the XSi but I kept it and have debated the benefits of going with the 70-300L since this lens isn't used very often - but when it is the pictures are often on once in a lifetime trip)
We're likely adding an HD video camera to the mix as my wife doesn't feel comfortable with the lack of full-time autofocus on the 60D.
Up until now, my primary use has been photographing my pet snakes. The 15-85 and 60mm macro get that duty. Secondary use has been any outings/trips (zoos, outdoor events, Australia, Costa Rica, etc.) we embark upon and that's where the 55-250 gets some use.
I'm coming from a realm far different than baby/portrait photography. One where, in my circles, a deep depth of field is important to showcase an entire snakes body. I often shoot between f8/f13 with my current lens lineup. I'm looking forward to having a baby for many reasons but in the photography realm, I'm very excited about challenging myself and pushing my creativity by photographing people instead of scaly critters
I'm wondering what might be the best avenue for a lens that will pull heavy-baby-duty (especially indoors). The 4 options I'm currently considering are:
60mm macro - I'm considering this because I've read a few reviews here and there that the other options I'm considering are best when stopped down to at least f2.8 and that's where this lens starts. I already have it and am familiar with it - so why change?
50mm 1.8 - I'm considering this because of all of the rave reviews. A lack of USM concerns me (just how loud is it? Loud enough to attract a baby's attention and ruin a "moment shot" or worse, wake a sleeping baby?) and I'm curious about the trade off of stopping down to increase DOF and the compromise of less light. Also, is this focal length appropriate for baby shots on a crop sensor camera?
50mm 1.4 - I'm considering this because of the USM and more light gathering than the 50 1.8. Same concern of stopping down and focal length.
28mm 1.8 - I'm considering this because the focal length/wide angle seems more appropriate for a crop sensor, its 1.8 max aperture, and the USM.
Cost really isn't a concern at this point (baby's not here yet, lol) as I'm okay with the price point of any of these lenses, but value definitely is a concern. For example, I don't want to spend $100+ on the 50mm 1.8 if the 60mm macro I currently have is just as good of a solution (no value). On the other hand, I don't mind spending $500+ on the 28mm 1.8 if it's the best solution for the job (great value). I don't believe I'd like to go too much further than $500 though so something like the 50mm 1.2 would be out of the question.
So, any advice/guidance/experiences? Are there other lenses I haven't considered and should (either inside the Canon portfolio or out of it)?
Thanks so much!
