Product Information

To my pleasant surprise, it doesn't suffer much from diffraction, even in the corners. My older 15mm f/3.5 AI-s got horribly soft, especially in the corners, at small apertures. Definition: An inch (symbol: in) is a unit of length in the imperial and US customary systems of measurement. An inch was defined to be equivalent to exactly 25.4 millimeters in 1959. There are 12 inches in a foot and 36 inches in a yard. The two share a similar shape, size - and of course, convex-shaped objective element with a fixed metal lens hood.

Bokeh is not usually the forte of ultra-wide lenses, but with an f/1.4 maximum aperture some differential focusing does become possible. The bokeh, the smoothness of those out of focus areas, is surprisingly good.The conversion factor from mm to inches is 0.0393700787. To convert any value of mm to inches, multiply the millimeter value by the conversion factor.

At this focal length, I don't find focus speed to be a real important factor ... but fast is always better than slow as long as it is accurate. Like all fixed ultra-ultra wide lenses I've used, the color balance becomes cooler (less red) in the corners. Few people ever notice this, but I do. I call this peripheral color shift: the colors get slightly bluer in the far corners. All fixed ultrawides do this. You can also choose from a selection of finishes that make the flooring more scratch resistant and alter its appearance. Is Engineered Wood Flooring Waterproof? On film, I can't see any, even wide open, until you get out to at least a radius of 16mm. Even then they are hard to see on film.

How much are 14 millimeters in inches?

History/origin: The milli- prefix is one of many metric prefixes. It indicates one thousandth of the base unit, in this case the meter. The definition of the meter has changed over time, the current definition being based on the distance traveled by the speed of light in a given amount of time. The relationship between the meter and the millimeter is constant however. Prior to this definition, the meter was based on the length of a prototype meter bar. In 2019, the meter has been re-defined based on the changes made to the definition of a second. Inch very fast, as it usually is for ultrawide lenses. One full turn of the AF screw pulls the focus from infinity down to 1.5' (0.5m).
