In questa sezione verranno presentate via via le foto scattate con gli obiettivi Minolta MC/MD Rokkor sul sensore CMOS APS-C con alcune DSLR CANON: EOS 300D (6.3 MP), 20D (8.2 MP) e l'ultima EOS 450D (12.2 MP).

This section shows the photos taken with the Minolta MC / MD Rokkor lens on some DSLR CANON with APS-C sensor: EOS 300D (6.3 mp), 20D (8.2 mp) and latest 450D (12.2 mp).

Sono disponibili sia immagini in formato RAW che in JPG (sempre a piena risoluzione). I file RAW, ovviamente, riporteranno tutti i dati di scatto (escluso il diaframma impostato che verrà indicato a parte) mentre per i JPG si farà riferimento ai principali dati: tempi, diaframma ed iso impostati. Verrà indicata di volta in volta l'ottica MD/MC Rokkor utilizzata nonchè, in alcuni casi, il tipo di messa a fuoco eseguita (infinito, iperfocale, ...). Per ogni obiettivo verrà inoltre fornita una breve scheda tecnica ed un sintetico commento personale che evidenzia le prestazioni ottiche rilevate. Una tabella delle prestazioni, ottenuta a partire da valutazioni personali derivanti esclusivamente da un utilizzo "sul campo" e quindi non utilizzando metodi rigorosi di calcolo delle prestazioni (MTF e simili), fornirà una indicazione generale sull'utilizzabilità nonchè sul comportamento riscontrato nella realtà pratica, per ogni obiettivo preso in esame.

Images are available in both format: RAW and JPG (always at full resolution). RAW files, of course, will report all data shooting (except the lens aperture shows separately) while for the JPG will reference only to the main data: time, lens aperture and iso setting. Will be shown from time to time optics MD / MC Rokkor used and, in some cases, the type of focus performed (infinite, hyperfocal, ...). For each lens will also be given a brief technical sheet and a summary comment that highlights the performance observed. A table of performance, obtained from personal assessments and so not using rigorous methods of calculating performance (i.e. MTF and the like), finally gives a general indication on usability and on the behaviour found in the reality practice, for every lens under test.

Ho volutamente evitato di effettuare crop delle immagini in quanto tutti i particolari sono direttamente osservabili dai files RAW (per chi non lo sapesse: il file RAW è il "negativo digitale" ) e JPG. Tutte le immagini sono state scattare con la fotocamera CANON EOS DSLR impostata in modalità "M" (Manuale) ed in alcuni casi "AV" (Priorità di diaframma).

I have deliberately avoided making crop images because all the details are directly observable by the RAW files (for those who have not known: the RAW files is the "digital negative") and JPG (at full resolution). All images were shooting with the camera CANON EOS DSLR set in "M" (Manual) and in some cases in "AV" (Priority Aperture) mode.

Infine, le grandi dimensioni dei file RAW ed il limitato spazio sui server rendono difficile l'inserimento di immagini, per ogni obiettivo in esame, per ogni valore di diaframma. Per questo motivo alcune immagini potrebbero essere via via sostituite (i rispettivi file RAW/JPG saranno marcati con la dicitura "Rimossa") da altre con differenti valori di diaframma impostato.

Finally, the large RAW files and limited space on the servers make it difficult to insert images, for each lens under test, for each value of lens aperture. That is why some files could be gradually replaced (their RAW files / JPG will be marked with the words "Rimossa") by others with different values aperture set.

IMPORTANTE: tutti i files di immagine possono essere scaricati sul proprio computer locale per sola visualizzazione (i files occupano da 2 a 4 Mbyte per i JPG, oltre 6MB per i RAW). Anche se le immagini presentate sono da intendersi puramente dimostrative, ovvero senza alcuna valenza "artistica", è assolutamente vietato il loro utilizzo per qualsiasi altra forma, oltre a quella di sola visualizzazione già citata, non espressamente autorizzata dall'autore.

IMPORTANT: all image files can be downloaded in your computer for display only (the files are from 2 to 4 Mbytes large for JPG, as well 6-9 MBytes for RAW). Even though the images presented are intended purely demonstrative or without no value "artistic", is absolutely prohibited their use for any other form, in addition to that of view only cited above, not expressly authorized by the author.
