Translation of "Offenblende" in English

The sharpness in open aperture is exceptional.

With open aperture a transmission of T1.9 is achieved.

The rounded diaphragm produces an attractive round bokeh effect at large-aperture settings.

Even at widest aperture, this lens delivers breathtaking image quality.

With maximum aperture f1.8, short shutter speeds and thus sharp shots were possible even with low light.

It is the balance between perfection and character. At open aperture center-weighted auto exposure tends for both lenses in a slight under-exposure, since the brightness decreases towards the edges.

The maximum aperture of F/2.8 allows you to play around with the depth of field to create the right atmosphere, although for optimum sharpness, I recommend stopping it down one to two levels.

The large maximum aperture of f/1.8 still provides a pleasant background blur and thus a beautiful exposure of the motif, even with a slightly larger distance to the motif.

We weren't used to the ISO performance and great sharpness of the Tamron even with the wide aperture, and with the image stabiliser in the mix as well, we even got great photos hand-held and at night.

When photographing with point light sources such as electric lights or reflections on a body of water in the background, the rounded 9-blade diaphragm helps produce an attractive bokeh effect—even at large-aperture settings.

Ok, in compare to the highest aperture is it a difference, but still not a lot.

The first point is this mostly uncompromising sharpness even wide open and in the edges. But the most important point for me is the wonderful bokeh from this lens.

With SLR cameras, the central shutter first closes after the shutter release, because all the settings were made with an open shutter.

With the open aperture of F/2.8 it is also bright enough that I can also make beautiful pictures indoors with the available light.

When photographing with point light sources such as electric lights or reflections on a body of water in the background, the rounded 9-blade diaphragm helps produce an attractive bokeh effect—even at large-aperture settings.

This function allows you to use targeted fill-flash against the sun or to reduce or eliminate ambient light and is ideal for isolating the subject from the background using flash shots with the aperture fully open.

The object in focus is beautifully set in scene, while the background (at open aperture) is immersed in a wonderfully soft bokeh.

The intensity of the light can be adjusted smoothly from 20% up to the maximum level. This is a particularly useful feature when taken macro images when the aperture is at its fullest extent.

The object in focus is skillfully set in scene, while (with open aperture) the background merges into a wonderfully soft bokeh.

Both high definition rendering without chromatic aberration and natural bokeh expression are possible, even at maximum aperture.

The illustration of the crop factor relationship shown abovealso indicates the vignetting and slightly recognizable loss of edge sharpness of theNoctilux 1.0 at open aperture when attached to a full frameLeica M9.

In particular, the 15-30mm with its unique combination of the 2.8 open aperture and image stabiliser is predestined for photography in twilight, and has convinced me in every aspect.

The special feature of this lens is the wide open aperture of 1:1.4 which allows pictures with a quite short depth of field and at low light and the auto focus mechanism using an ultrasonic motor (USM) which allows continuous manual override even then auto focus is turned on.
