If I could I would have tried to position the subject more to the left to have it all in the frame, I think nothing of the valid shot that well highlights the head would have been lost. Potendo avrei cercato di posizionare il soggetto più a sinistra per averlo tutto nel fotogramma, penso non si sarebbe perso nulla della valida ripresa che ben evidenzia il capo. |

hello unfortunately I happened too close and there was in the frame, it remained a few seconds and I did not have time to compose the photo better ... as the first time I see it is fine so '.. it was an emotion ciao purtroppo mi è capitato troppo vicino e non ci stava nel fotogramma , è rimasto pochi secondi e non ho avuto il tempo di comporre meglio la foto... come prima volta che lo vedo va bene cosi' ..è stata un'emozione |

Beautiful shot, congratulations, but... I need to get rid of a doubt, since I would like to buy my first Sony camera... (I own 3 professional Nikons).
I would like to take the A6700 which is an APSC (multiplication factor for full frame lenses equal to 1.5), and I was wondering if the aperture, in addition to the focal length, should also be multiplied by 1.5?
That is, the exif data of the shot says f/5.6 at 200mm, but really it would be an f/8.4 at 300mm ???
Or am I wrong in my calculation?
Thank you for your time.
Hello Bellissimo scatto, complimenti, ma... ho bisogno di togliermi un dubbio, visto che vorrei acquistare la mia prima fotocamera Sony... (possiedo 3 Nikon professionali).
Vorrei prendere proprio la A6700 che però è un APSC (fattore di moltiplicazione per le lenti full frame uguale a 1,5), e mi chiedevo se anche l'apertura del diaframma, oltre che alla lunghezza focale, debba essere moltiplicata per 1,5?
Cioè, i dati exif dello scatto dicono f/5.6 a 200mm, ma realmente sarebbe un f/8.4 a 300mm ???
Oppure sbaglio nella considerazione?
Grazie per il tempo che vorrai dedicarmi.
Ciao |

The aperture remains constant... it's a 300 f5.6...the aperture is on the lens.... It doesn't change based on the size of the sensor... The maximum aperture of the lens in the wide-angle and telephoto position does not change. For APS-C lenses, the focal length, aperture, minimum safe time, and depth of field all remain the same. Only the angle of view changes, it doesn't change the perspective either!
L'apertura del diaframma rimane costante...è un 300 f 5.6...il diaframma è sull'obiettivo....non cambia in base alle dimensioni del sensore...L'apertura massima dell'ottica nella posizione grandangolare e tele non cambia. Per gli obiettivi su APS-C la focale, le aperture di diaframma, il tempo minimo di sicurezza e la profondità di campo rimangano tutte invariate. Cambia solamente l'angolo di campo, non cambia neanche la prospettiva!

Thank you Gianni Dalla Costa.
Very clear from a purely technical point of view.
Unfortunately, the problem most likely stems from a concept of conventions assumed in the past, when I started to hear about "equivalent focal length" in FF lenses used in DX camera bodies.
This had created a lot of confusion for me, but now I have cleared it up thanks to You.
Hi
Donato Grazie Gianni Dalla Costa.
Chiarissimo dal punto di vista prettamente tecnico.
Purtroppo il problema, molto probabilmente, nasce da un concetto di convenzioni assunte nel passato, quando ho iniziato a sentire parlare di "focale equivalente" negli obiettivi FF utilizzati in corpi macchina DX.
Questo mi aveva creato non poca confusione, che però adesso ho chiarito grazie a Te.
Ciao
