Extensive user feedback and sample photos by Keith Schmidt
Read every post by Keith in that DPReview forum thread to get a good idea how well this lens performs. Keith comments on the lens’ AF (autofocus) & OS (optical / image stabilization) performance, sharpness, contrast, CA (chromatic aberration) and makes some comparisons with the Sony SAL 18-250mm lens.
He’s also posted up a gallery of full-resolution Sony A700 plus Sigma 18-250 images, which has photos ranging from portraits to still life to close-ups / macros.
The RAW images were processed with Adobe Photoshop Lightroom.
