For quite a while I have the sigma 120-400 at max focal length. My shots, especially with distant subjects were always poorly defined.
Then yesterday I discovered by accident that the maximum focal length of the sigmoid kneads a lot and that just reduce a little the shot to gain definition. Of course, I still have problems with the shake-but I would say that the difference begins to be noticed .... what do you think?
This is one of two copies of the purple heron, noted last week at the lagoon of Capoterra (CA). Per un bel pò ho il sigma 120-400 all max lunghezza focale. I miei scatti, soprattutto con soggetti lontani erano sempre poco definiti.
Poi ieri ho scoperto per caso che alla massima lunghezza focale il sigma impasta tantissimo e che basta ridurre un pò il tiro per guadagnare in definizione. Certo, ho ancora problemi col micromosso, ma direi che la differenza comincia a notarsi....che ne dite?
Questo è uno dei due esemplari di airone rosso, già osservato la settimana scorsa presso la laguna di Capoterra (CA). |

Great shot Ottimo scatto |

Well, at that distance is not easy to focus properly, especially herons that you focheggiarli head and it's easy to go over the fire, you should try with individuals more neighbors to see if you have problems with front or back focus, not counting the stability of the equipment, and more. beh, a quella distanza è facile non mettere bene a fuoco, specie gli aironi che devi focheggiarli in testa ed è facile che il fuoco vada oltre, dovresti provare con soggetti piu vicini per vedere se hai problemi di front o retro focus, senza contare la stabilità dell'attrezzatura e altro . |

I agree with Franco, with a subject that fills the frame can check whether your machine has problems with front or back focus.
As light measurement uses "spot metering" for the maf uses a single point (the eye point), reassemble and shoot.
The shake-is affected by the shutter, whether they comply with the safety time (for a 400mm is equal to about 1/640) you should not have problems. Concordo con Franco, con un soggetto che riempe il fotogramma potrai verificare se la tua macchina ha problemi di front o back focus.
Come misurazione della luce utilizza "misurazione spot", per la maf utilizza un unico punto (punta l'occhio), ricomponi e scatta.
Il micromosso è influenzato dal tempo di scatto, se rispetti il tempo di sicurezza (per un 400mm è pari a circa 1/640) non dovresti aver problemi. |

Nice catch to saturate in a bit ;-) .... the maf have said it all
Hello, paolo Bella cattura da saturare un pelino  ....sulla maf hanno già detto tutto
Ciao, paolo |

Quoto Franco on maf and Mommotti on saturation that would help.
Greetings
Carlo Quoto Franco sulla maf e MOmmotti sulla saturazione che avrebbe aiutato.
Saluti
