p.1 #1 · p.1 #1 · Sigma 50-100 f/1.8 users?


Does anyone here have any experience with this lens?
The reviews i have seen on-line so far seem pretty positive, but i have only just started researching this lens.
I will be using this on a D7100. I already have 2 f/2.8 zooms (17-50 and 70-200) but i am looking for something different and was considering a f/1.4 prime in the 50-100mm range as i want the option the really blur out the background which is harder on a crop sensor camera.
The dilemma i am having is will an f/1.8 zoom lens provide enough subject isolation and IQ on a crop sensor and will it be a big enough difference from my f/2.8 lenses or is it better to go with a f/1.4 prime but give up the versatility of a zoom when i am struggling to decide on what focal length to get.

I don't know how much this Sigma costs, but if you want f/1.4 your only option is probably is either 50 or 85mm? I think you have to decide first if you like those focal lengths. You can use your zooms at those FLs and see how you like it.
f/1.8 is 2/3 of a stop slower than f/1.4 but still 1 1/3 stop faster than your f/2.8 zooms.
