I've checked up this lens and it looks quite good with affordable price. But there is no IS feature which makes me think. I wonder that does absence of this feature lead any problem on photo, such as blurry results ? As far as i know to prevent this problem with IS missing lens, i have to use low shutter speed values. Now my question is how low should it be to avoid blurry photos ? Also with 1.8 aperture size it looks quite useful for night photos, but if i decrease the value of shutter speed then i need to use high iso for night photos and that leads to noise on photo. Actually my main concern about relation of shutter speed and blurry photo So can i get good night shots without blur ?
