3.0 out of 5 starsNice lens, good value, but no U.S. warranty from most Amazon sellers
Reviewed in the United States on October 29, 2023
First, a caution for Amazon buyers: Although listed as having a 4 year warranty (which is standard for Sigma lenses), you must buy from a U.S. Sigma authorized importer or dealer for a valid warranty in the U.S. I bought from an Amazon seller who wasn't authorized by Sigma, so the warranty is only honored in Japan. I returned it after Amazon and the seller both agreed to the free return, but since it's a "high value" product (as defined by Amazon), the return processing will take up to 5 weeks. I'll buy this lens again once I get my money back, but not from Amazon. Beyond that I was pleased with the image quality and focus with this lens, although it's not as sharp at max 400 zoom as I'd hoped. Autofocus in the 1m-6m low range is fast and accurate, and almost as responsive in extended range setting. It's a good lens for wildlife and landscapes, but range of lighting conditions for best results is limited to daylight, not as effective in low light shadow, evening, or indoor situations. Bottom line... A fine lens for those who want higher zoom, well worth the cost, but verify before buying that the seller is Sigma authorized if you want the U.S. 4 year warranty. **Update 11/1 - A third call to Amazon customer service routed me to a supervisor who, although he couldn't manually process the return, sent a message to the right Amazon contact to expedite the return, and the full price was credited to my card the next day. Very pleased with customer service resolution.
