[QUOTE="Pretzel, post: 519482, member: 12257"] Again, just some performance testing. 1st, a semi-close shot, normal wood screw in front of a regular sized coffee cup. No cropping. [ATTACH type="full"]192304._xfImport[/ATTACH] Gettin' CLOSE UP on the same screw. No cropping. [ATTACH type="full" width="60%"]192305._xfImport[/ATTACH] Then a 100% crop of the above pic in a square format... you can see the scarring from where this screw has been used before. [ATTACH type="full" width="60%"]192307._xfImport[/ATTACH] Then, this is an uncropped shot with the Raynox DCR 250 mounted on the Sigma. DOF suffers greatly... not cropped. [ATTACH type="full" width="60%"]192306._xfImport[/ATTACH] And a 100% crop of that shot. With the DCR 250, the DOF is razor thin... this was at f20. I think I like normal shooting with a crop vs. the DCR 250 on the macro, as you have to get [I]extremely[/I] close to your subject, but it will have it's uses, I'm sure. That, and a mandate to learn how to create 20 shot focal stacks. LOL [ATTACH type="full" width="60%"]192308._xfImport[/ATTACH] [/QUOTE]
