Well the Sigma 30mm 1.4 arrived Monday the 29th and boy is it a real beauty. I am very excited about the addition of this lens to the kit, it offers such a wide scale of uses that it should be about the perfect lens for most areas. They incredible thing about the 30mm Sigma is the super large 1.4 aperture. An aperture this large is a true blessing with low-light situations in which you are either not allowed to use a flash in or do not want flash for artistic purposes.
Again the other benefit to this aperture is the extremely shallow Depth of Field it provides. Everyone has seen those photos (particularly portraits) where the subject pops out at you from a blurred background. This blurred background or “Bokeh” (a Japanese word) is a direct result of a couple of things, focal length of the lens, distance of subject from background, and the size of the aperture shot with. Seems odd but the lower the number the larger the aperture ex…f1.4 (huge) f16 (tiny) the number increments in between are referred to as stops.
I have not had a chance to give the lens a thorough running through and hope to have some great examples of what the lens is capable of. For starters here is a shot taken with the E3 and Sigma 30mm 1.4. Very unscientific, yet it demonstrates how shallow the DOF really is at f1.4…the focus point is at the 9 inch mark.
Thats all for now-
