The following opinions have been automatically translated with Microsoft Translator. | Canon RF 24-105mm f/4-7.1 IS STM Pros: Small and lightweight, but with excellent optical quality already from the maximum aperture, in a good compact construction, which also includes an aspherical lens. Up to 50 mm, bright enough for almost any use. Beyond it is still fine in most situations. 0.34 m to 105 mm, allow you to make excellent close-ups. Great lens to take pictures (less to do tests ...) and to have a really compact and inconspicuous FF, without compromising on quality. Cons: For the use for which it is intended, I would say none. I read that others complain about sharpness, but I have absolutely not found this defect. Perhaps, as the previous speaker pointed out, there will be less performing copies in circulation, since the construction is certainly not from the L series. Opinion: In order not to repeat what has already been written in the pros / cons, I only add a consideration on the maximum aperture at 105 mm. On paper f/7.1 it really looks like crap, but then on the field you realize that: 1) it is only 2/3 stop less bright than its poor brother EF; 2) For landscape photos it is not necessary to have a greater aperture, on the contrary; 3) For portraits, the difference in blurred compared to an f / 4 of the rich brother, is seen only in some situations and is not dramatic (if I want a beautiful blurred f / 4 is not enough anyway). If you want to make a significant leap in brightness (and therefore not to a modest f/ 4), just combine it with a small canvas (eg EF 100 f / 2, but also RF 85 1.8). In short, a modern lens, which does not chase the latest exotic fashions and that cares about the hard. N.B. I have had this lens for about a year and it remains my favorite choice for light travel with my EOS-R, as well as for mountain excursions, motorcycles or bicycles. The only alternative when I need even more lightness and agility, is the 50 F 1.8. sent on August 08, 2022 |
 | Sigma 15mm f/2.8 EX DG Diagonal Fisheye Pros: Luminoso e nitido anche a TA; Bello sfuocato a f/2.8 ed ottima iperfocale a f/8; 12.5 mm "rettilieno"; Piccolo e leggero ma robusto. Cons: AF lenta (ma non e' un vero problema); Effetto fish eye (diagonale) poco pronunciato. Opinion: Luminoso e nitido anche a TA, ma capace di una messa a fuoco a 15 cm, con prospettive nuove e molto interessanti, accompagnate da un ottimo sfuocato a f/2.8, oppure da nitidezza quasi infinita a f/16; MF sufficientemente "ferma" da lasciarlo in iperfocale (a f/8 va da 50 cm ad infinito). Ha un effetto fish eye poco pronunciato ed e' quindi facile da "defishare" con un click in LR: Diventa cosi' un ottimo 12.5 mm equivalente nitido da lato a lato. Ho fatto un breve confronto con il 16-35 Canon @ 16 ed il 12 CV (montato su Sony A7). Senza correzione il 15 FE e' molto piu' ampio del 12 CV, mentre "defishato" e' leggermente piu' stretto (diciamo 12.5 circa). In ogni caso e' sempre molto piu' ampio del 16-35 a 16. E' quindi un piccolo, leggero, nitido e robusto UWA, che in PP puo' diventare un 12.5 rettilineo, oppure rimanere fish eye (se usato bene per certe foto di paesaggio, l'effetto fishe eye non si nota) con una copertura che potrebbe essere quella di un 10 mm rettilineo (?). Ovviamente rimane anche un fishe eye da usare come tale, quando si vuole ottenere quel effetto. CONCLUSIONE: Obiettivo con ottima IQ e molto versatile, che copre tantissime applicazioni e permette d'essere creativi con modalita molto diverse. sent on September 17, 2015 |
 | Canon 5D Pros: Quality 'in exceptional image size. It also works well with objectives not exceptional. Excellent autofocus. Very fun and rewarding to use. Deep blacks, high dynamics and basal noise. Cons: Nothing serious: You might have a better screen and more 'and a big gust a bit' more 'menu. The auto ISO (the real one that also works in M) would be nice. Opinion: The sensor FF with photodiodes very large and the lack of aggressive anti aliasing filter ("the Japanese"), produce images that few other digital able to churn. Very similar to the film depth 'and dynamic. Thanks to the large photodiodes works fine with any lens and allows you to close a lot of the diaphragm without losing sharpness. Well perhaps the digital FF miles for those who are 'born (photographically) with the foil, and' therefore able to take advantage of this wonderful machine. sent on September 11, 2011 |
