<p>[QUOTE=&quot;benveniste, post: 2663826, member: 25547&quot;]True, but not as much as claimed.&nbsp; Hence it&#039;s an exaggeration.&nbsp; At 1:1, you will have virtually the same working distance with either Nikkor as with a 75mm enlarging lens.&nbsp; Ray claimed otherwise.</p><p><br /></p><p><br /></p><p><br /></p><p>I&#039;ll ask you the same thing.&nbsp; Please post a shot of your setup and explain how it <u>severely </u>limits things.&nbsp; Ray refused to do so.</p><p><br /></p><p><br /></p><p><br /></p><p>I&#039;ve done it in the real world with modern arca-swiss based gear, so now we&#039;re both guilty of overgeneralizations.&nbsp; Quantify, please, so I can compute what effect if any it would have on depth of field or angle.</p><p><br /></p><p>And once again, I&#039;ll point out that when used on a copystand, a bellows adds rigidity challenges rather than solves them.&nbsp; Ray ignored this as well.</p><p><br /></p><p><br /></p><p><br /></p><p>I understand that advantage in theory, and if anything I said implied that Nikon was better than Canon for this I apologize.&nbsp; Nikon/Canon &quot;debates&quot; have never interested me; again, it&#039;s tools for artisans.&nbsp; The original poster asked about Nikon and I&#039;ve been a Nikon user long options such as electronic shutters were available. So I spoke to what&#039;s available from that brand.&nbsp; What I&#039;m not sure (and what Ray didn&#039;t prove) was how much was due to mirror slap (not an issue with a D800 in live view) and how much to the shutter.</p><p><br /></p><p><br /></p><p><br /></p><p>Yes, because it&#039;s not just about the adjusting screw.&nbsp; Since I don&#039;t dedicate my camera to coin shots I don&#039;t leave my camera mounted on a tripod or copy stand full time there&#039;s less setup time. Once I&#039;ve added the extension tube, say a 20mm tube, I can focus between 0.2x and 1.25x by adjusting the height of the camera on the stand, so I don&#039;t need to subtract and I still retain the ability to tweak focus on the lens or (*gasp*) use live view autofocus.&nbsp; Still once you move beyond 1:1 bellows become more valuable, which is why I own one.&nbsp; </p><p><br /></p><p>I do notice the aspect ratio on your second shot is off, which means that either something went horribly wrong in post or the coin wasn&#039;t aligned with the focal plane.&nbsp; In effect, you just demonstrated the problem you claim would happen with sag to a much larger degree.&nbsp; Tell me -- how much did it impact DOF?&nbsp; I didn&#039;t think so.</p><p><br /></p><p><br /></p><p><br /></p><p>I&#039;m glad it works for you since you are willing to dedicate an SLR to the task.&nbsp; If you read my original response, I outlined why I felt (and feel) that for most people starting out using a macro lens is a better and easier alternative.&nbsp; You may have noticed that both Nikon and Canon gave up selling bellows long ago, and Nikon currently only sells one enlarging lens and that&#039;s through industrial channels.&nbsp; It&#039;s worth musing on why.[/QUOTE]</p><p><br /></p>
