- Excellent sharpness throughout the zoom range
- Good build quality
- Constant f/4 maximum aperture
- Effective optical stabilisation
The Canon equivalent, the Canon EF 24-105mm f/4L IS USM costs a bit less (actually: $635 on eBay). We have to wait for a direct comparison to see which one is better. In their conclusion ephotozine writes:
With their latest lens releases, Sigma appear to be changing their past image of a manufacturer of lenses that are less expensive than the major camera manufacturers, instead concentrating on lenses that deliver performance to rival the best available.
This lens certainly is capable of producing outstanding clarity, at a price that is comparable to those of camera manufacturers own lenses. It should certainly be considered as a viable alternative if you’re in the market for a lens of this specification.
