I am looking to capture some baby photos over the next few months (first child due next month). I have the Canon 550D with the the following equipment:
- 15-85mm f/3.5-5.6 IS lens: Very good image quality, but limiting for indoor shooting, particularly on the long end. I have used ISO 6400 in some scenarios without a flash, but found the results quite poor, as expected.
- 50mm f/1.8: Quite handy indoors and very good quality images, but can get a bit long in confined spaces. Focus speed is also pretty slow.
- Metz 44 AF-1 flash with tilt & swivel head: Powerful, but not convenient for candids
From what I have read on the site, it seems that people recommend the primes in the 24-50mm range for baby photos, especially on cropped sensor bodies (flash is recommended too). To that end, I was considering the Tamron 28-75mm f/2.8 and have found that it has a pretty good reputation for its image quality (particularly on cropped bodies) on review sites. It is also a fairly fast and in the ideal portrait focal length range.
Should I consider this lens given my current equipment? Are there any other options for this purpose (budget around $500-600), keeping an eye on the future requirements as the baby grows?
