B&H has Canon EF 50mm f/1.4 USM for $299. That's very tempting. I have the nifty fifty on crop sensor T2i. Is it really that big of a difference in sharpness?
Dpreview comparison between f/1.8 and f/1.4 shows there isn't that much of a sharpness difference on crop sensor body. If I read the chart correctly the f/1.8 outperforms f/1.4 from f/3.3 to f/5.6. Did I misread the chart?
Is the upgrade worth it?
