| Re: sigma 170-500mm or 150-500mm?
I was considering this lens and after a lot of research on net and forums steered away for reasons Fourwings states above .
The Sigma 100-300f4 gets good reviews , think you need to pay a bit more for good quality glass on longer focal lengths .
I had a Sigma 135-400mm but was unhappy with the pq at 400 , eventually saved a bought a s/h Sigma 300f2.8 + TC. |
