next PZ lens test report: Leica DG Vario-Elmarit 12-60mm f/2.8-4 ASPH Power OIS
Thanks, Klaus.


If I may make a suggestion - which may go against some of the shallow-DoF-bokeh-advocates, regarding the first paragraph in the Bokeh-section:


Quote:Micro-Four-Thirds may not be the hot-spot for shallow depth-of-field applications yet there's still some potential if you can keep a fairly close focus distance - so let's have a look at some details.

Bokeh is not about shallow DoF, but about the quality of out-of focus areas, both transitions and completely OOF-regions. This gets more difficult to show with smaller sensor lenses, and/or with smaller aperture lenses, but is not necessarily inherently related to large aperture lenses anyway.


IMO, some great examples are the Canon TS-Es, which are all mostly relatively small aperture lenses, but provide incredibly smooth OOF transitions and generally have great bokeh.


I haver added an example here, which I use when showing people what a tilt-shift lens allows one to do beyond the miniaturisation effect, and which was shot with an APS-C camera and the older 24 mm F/3.5 Canon TS-E, wide open, IOW, effective FF-equivalent F-stop of F/5.6 (3.5 * 1.6).




These lenses do not have problems with long, sharp-edged items either, like blades of grass in the (relative) distance, where other lenses have a very busy characteristics; these lenses still show very smooth transitions, despite being small aperture lenses.


In short, my suggestion would be to rephrase the bokeh-paragraph, as nice bokeh can be achieved at almost any aperture Wink, although it is easier to show at larger apertures, with larger aperture lenses designed for and used with larger sensors.


Kind regards, Wim
