Comparision Sigma 17-70 and DA*16-50?
Does anyone have any comparison photos between Sigma 17-70/2.8-4,5 and Pentax DA*16-50/2.8?
They should be done at equal conditions: at 17mm/2.8 and 50mm/f4 etc...
I saw comparison between Sigma 18-50/2.8 and DA*16-50 at Ricehigh blog and I would be interested in Sigma 17-70 also...
I am planning to replace my Sigma 18-200 with something better, but I am still tempted to longer focal range - 50mm is just to short for me.
Or the comparison photos of two Sigmas: 18-50 vs. 17-70?
