prusaprinters
<p>If you are interested in making photos with 19th century optics but do not have the time and resorces to get into large format photography I designed something that might be of use to you.</p> <p>This adaptor allowes you to use old, large format lenses with modern cameras.</p> <p>It consists of two 3D printed adaptors (one acts as a lens board and one connects bellows to the camera) and also m42 macro bellows (they are probably the cheapest and you do not need more than one sliding control).</p> <p>I use this with a Sony a6300 so the back adaptor is m42 to E-mount.</p> <p>The extension of the bellows limits compatible focal lenghts, I tried it with a 300mm and infinity focus wasn't approachable.</p> <p>The lens used for sample photos is a Petzval design from a late 19th century magic lantern and it gives some very interesting results.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Craftbot2</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>No</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>200</p></div> <p><strong>Infill:</strong></p> <p>10% grid</p> <p><strong>Filament:</strong></p> Noctus PLA <p>Black</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>.</p></div> Post-Printing ============= <p class="detail-caption"><strong>.</strong></p> How I Designed This =================== <p class="detail-image"><img src="https://.s3.amazonaws.com/?AWSAccessKeyId=AKIAJ4LU5KWCMM7WB7YA&Expires=1632312853&Signature=JuKgZiqb5Pa7wGLDthGG%2B%2BV2Rzc%3D"/></p> <p class="detail-image"><img src="https://.s3.amazonaws.com/?AWSAccessKeyId=AKIAJ4LU5KWCMM7WB7YA&Expires=1632312854&Signature=3RbezCiSZA2Jk4q8nJ8dL4Ap8dE%3D"/></p> <p class="detail-image"><img src="https://.s3.amazonaws.com/?AWSAccessKeyId=AKIAJ4LU5KWCMM7WB7YA&Expires=1632312854&Signature=3RbezCiSZA2Jk4q8nJ8dL4Ap8dE%3D"/></p> <p class="detail-image"><img src="https://.s3.amazonaws.com/?AWSAccessKeyId=AKIAJ4LU5KWCMM7WB7YA&Expires=1632312855&Signature=llkv9vUgDf9SACVxP6fXdlBgKKg%3D"/></p> <p class="detail-image"><img src="https://.s3.amazonaws.com/?AWSAccessKeyId=AKIAJ4LU5KWCMM7WB7YA&Expires=1632312855&Signature=llkv9vUgDf9SACVxP6fXdlBgKKg%3D"/></p> </p></p> Category: Camera
