Sigma 18-200mm F3.5-6.3 DC Macro OS HSM | C samples gallery

Sadly, it appears to be still the same 18-200 OS HSM I had few years ago: very soft on long end, pronounced CA wide… Bokeh is nervous as it’s always been. This lens (assuming it does the same as the previous model, based on samples here) is great for close-up shots zoomed in but in other aspects nothing to impress much. I couldn’t see any shots done at 35-37mm focal length nor about 85-90mm (this is where the previous version had both stiffer zoom operation AND it could not have a correct focus regardless what you tried, including MF). I’m not convinced this lens would mate well with 24MP. Sigma has some other lenses done pretty well, some of primes are perhaps in top range – but looks like 18-200 zoom, regardless how many times they re-do its design, will not be an award winning piece of optics.
