Either way, the lens provides an incredibly high imaging performance.<br><br> </div> <div></div> <div> <p>Without the adapter, the Leica Macro-Elmar-M 90 mm f/4 is an extremely versatile telephoto lens – for example, for portraits with shallow depth of field and in travel photography for capturing details in landscapes. For reportage photography, the Leica Macro-Elmar-M 90 mm f/4 allows photographers to capture discreet shots at a greater distance from the subjects. The Leica Macro-Elmar-M 90 mm f/4 is a compact and lightweight alternative to existing Leica M-Lenses of this focal length. When not in use, the lens can be collapsed to save valuable space in the camera bag.</p> </div> </li> <li id="tab2"> <table width="100%"> <tbody> <tr> <td width="50%"><strong>Angle of view (diagonal, horizontal, vertical)</strong></td> <td> <div> 27° / 23° / 15° (M8: 20° / 17° /11°)</div> </td> </tr> <tr> <td><strong>Optical design</strong></td> <td> <div></div> <span></span> </td> </tr> <tr> <td><strong><span>Number of lenses/groups</span></strong></td> <td><span><span>4 / 4</span></span></td> </tr> <tr> <td><strong><span><span>Focal length</span></span></strong></td> <td>90.0 mm</td> </tr> <tr> <td><strong><span><span><span>Position of entrance pupil (from bayonet flange)</span></span></span></strong></td> <td> <div>22 mm </div> </td> </tr> <tr> <td><strong><span><span><span>Focusing range</span></span></span></strong></td> <td>0,8 m to ∞</td> </tr> <tr> <td><strong><span><span><span><strong><span><span><span>Distance setting</span></span></span></strong></span></span></span></strong></td> <td><span></span></td> </tr> <tr> <td><strong><span><span><span><span>Scales</span></span></span></span></strong></td> <td><span>Combined meter/feet graduation</span></td> </tr> <tr> <td><strong><span><span><span><span>Smallest object field</span></span></span></span></strong></td> <td>169 x 244 mm (Adapter 72 x 108 mm) M8:122 x 183 mm (Adapter: 36 x 54 mm)</td> </tr> <tr> <td><strong><span><span><span><span><span>Largest reproduction ratio</span></span></span></span></span></strong></td> <td> approx. 1:6,7</td> </tr> <tr> <td><strong><span><span><span><span><span>Aperture</span></span></span></span></span></strong></td> <td><span></span></td> </tr> <tr> <td><strong>Setting/Function<span><span><span><span><span></span></span></span></span></span></strong></td> <td>prefix with click-stops, half steps, click-stop</td> </tr> <tr> <td><strong>Lowest value<span><span><span><span><span></span></span></span></span></span></strong></td> <td>22</td> </tr> <tr> <td><strong>Bayonet<span><span><span><span><span></span></span></span></span></span></strong></td> <td>Leica M quick-change bayonet with 6 bit lens identification bar code for digital M models</td> </tr> <tr> <td><strong>Filter mount</strong></td> <td>internal thread for screw-in type filters E39, non-rotating lens mount</td> </tr> <tr> <td><strong><span>Lens hood</span></strong></td> <td>separate metal lens hood, can be attached in reverse for storage</td> </tr> <tr> <td><strong><span>Dimension and weight</span><span>: </span></strong></td> <td></td> </tr> <tr> <td><strong><span><span>Length</span></span></strong></td> <td>59 mm (lens extended, in working position), 41 mm (lens collapsed, in storage position)</td> </tr> <tr> <td> <strong><span><span>Largest </span></span></strong><b>diameter</b> </td> <td>52 mm</td> </tr> <tr> <td><strong><span><span><span>Weight</span></span></span></strong></td> <td>Weight: approx. 230 g (black anodized aluminium version)</td> </tr> </tbody> </table> </li> </ul>
