Very interesting, it seems to me only to notice a slight lack of sharpness due to diffraction perhaps. Can I ask the shooting data? Specifically, I'd be curious to know the aperture used, as I noticed in some shots that I made with tubes, using an aperture greater than 5.6 is known a decay of sharpness. Hello Molto interessante,mi sembra solo di notare una leggera mancanza di nitidezza dovuta forse a diffrazione. Posso chiederti i dati di scatto? Nello specifico sarei curioso di conoscere il diaframma usato,in quanto ho notato in alcuni scatti da me effettuati con i tubi,che usando un diaframma superiore a 5.6 si nota un certo decadimento della nitidezza. Ciao |

? Canonft These are 3 shots with 72mm tube with a 60mm f16 1/30 iso 200. The tubes are then electronic calculation makes the machine if they were not electronic and closing of the diaphragm was in manual in reality it would be much more than f16. Normally with these shooting data I've always found a defrazione minimal, it is very noticeable when you're at the defrazione f22. The loss of sharpness and caused in part by the merger of three shots and perhaps at times by small tablets of file when converting to the web. Thanks for the ride! if you need to ask questions as well Hello. ;-) ? Canonft Questi sono 3 scatti con 72mm di tubi con un 60mm a f16 1/30 iso 200. I tubi sono elettronici quindi il calcolo lo fa la macchina se non fossero elettronici e la chiusura del diaframma fosse in manuale in realtà sarebbe molto di più di f16. Normalmente con questi dati di scatto ho sempre riscontrato una defrazione minima,si nota molto la defrazione quando sei a f22. La perdita della nitidezza e causata in parte dalla fusione dei 3 scatti e forse anche a volte dalla compressine del file quando si converte per il web. Grazie del passaggio !! se devi fare altre domande chiedi pure Ciao. |

Thank you for clarification, I use Sigma 150 macro and closing the diaphragm type f16 + 3 shots I noticed a loss of sharpness, that problem seems to be resolved by more shots (7/10) to f4. This I do not know if it depends on me, the lens / camera, or if it is the rule. With regards. PSIO use Kenko extension tubes. Grazie a te delle delucidazioni,io uso sigma 150 macro e chiudendo il diaframma tipo f16 + 3 scatti ho notato una perdita di nitidezza,problema che sembrerebbe essere risolto effettuando piu scatti (7/10) a f4. Questo non so se dipende da me,dall'obiettivo/macchina,oppure se è la regola. Grazie saluti. P.S.Io uso tubi di prolunga Kenko. |
