impatience ou ras le bol?
Pour l'instant je suis toujours à la recherche d'un 2870 A-F angenieux , j'en avais touvé un sur un shop net . mais j'ai téléphoné trop tard !! pour un peu plus de 320 ? si ma mémoire ne me fait pas défaut.

LCDI a écrit :Depuis que je fais un peu d'animalier, je ne souhaite que 3 choses
- Un viseur comme ou supérieur au D7D
- Un vrai AF
- 800 iso utilisable
Tout pareil, mais j'irais même jusqu'à rêver d'un peu plus de dynamique. En tout cas, je ne suis pas pressé, même si je butte clairement sur quelques lacunes de l'alpha 100, je m'éclate comme un petit fou avec cet appareil.
Ronan.
PS : A noter qu'il m'est arrivé de maudire l'AF ainsi que tous les ingénieurs qui l'on conçu sur 30 générations.

Amities.
Vous l'avez peut-être déjà lu, je le reporte ici tout de même ( source ) :
Here is my considered opinion:
The A300 will be APS-C and 12.x megapixels, and 5fps unlimited with a substantial RAW capability like the Canon.
The ?Flagship? will be 1.25X and 14.8 megapixels, with a similar shooting speed and sequence capacity, and may perhaps include interpolation to 20 megapixels.
That both will have entirely new AF modules and focus motors, new focusing screens and finder designs, improved SSS, better metering especially with flash, and other improved functions we can?t guess.
That the AA/A300 model will continue to disappoint by not offering 1/8000th top speed or 1/250th sync.
That the feature set and price position of the Canon 40D will oblige Sony to launch the AA/A300 at $1099 or under.
And that it will be announced early in September, with two weeks of the Canon announcement, and go on sale one month after the Canon.
And maybe Amazon will have the full pre-order specifications up for everyone to see next week

le flagship serait en x1.25, et non en x1.0 ou x1.1 ?
Et pourquoi ce format x1.25 ne serait-il pas simplement une pure web-invention gratuite, un rideau de fumée sans lendemain ?
Le prisme du flagship avait tout de même impressionné tout le monde... ça donnerait quoi devant un capteur x1.25 ? Un viseur 110% ?
ou alors le rabot des designers Sony est tombé en panne juste avant la PMA ?
A défaut, on va conforter la rumeur de l'impossibilité de stabiliser un capteur 24x36 ou approchant... que soulevait CI dans sa prise en main sur les derniers Olympus...
Et vous avez lu la réponse du même David Kilpatrick, dans les commentaires sous le lien de Gally, au sujet de la vitesse max de l'obturateur ? à 1/8000ème, l'AS/SSS ne suivrait plus (si je comprends bien), créant des artefacts ?

Je l'ai lu, ça voudrait dire que l'image serait finalement trouble ?
Ou qu'il aparaitrait sur l'image des effets/déformations aléatoires ?

ça, je n'en sais rien... mon niveau d'anglais ne me permettant pas de traduire entre les lignes de Kilpatrick
... mais à la rigueur, quelle importance : à 1/8000ème, l'image ne serait pas exploitable, point barre.
Sur Photim, l'hypothèse du flagship au format x1.0 ou x1.1 semble s'évaporer, pour les raisons évoquées plus haut, à savoir le rapport inertie/vitesse des moteurs SSS...
Le capteur x1.25, à l'état de pure rumeur à ce jour, serait pour lui...

Sur Photim, l'hypothèse du flagship au format x1.0 ou x1.1 semble s'évaporer, pour les raisons évoquées plus haut, à savoir le rapport inertie/vitesse des moteurs SSS...
Le capteur x1.25, à l'état de pure rumeur à ce jour, serait pour lui...

EGr a écrit :Et vous avez lu la réponse du même David Kilpatrick, dans les commentaires sous le lien de Gally, au sujet de la vitesse max de l'obturateur ? à 1/8000ème, l'AS/SSS ne suivrait plus (si je comprends bien), créant des artefacts ?
c'est quoi l'intérêt d'un stabilisateur à des vitesses telles que 1/8000 ? Et si c'est lui qui pose problème, on ne peut pas tout simplement programmer l'appareil pour le désactiver dès que le couple focale / vitesse permet la main levée nette ?
Quant à la synchro à 1/250, je considère que c'est le minimum syndical sur un boîtier cher.
Il serait temps que les constructeurs prennent en compte la taille du capteur quant à la synchro-X. Le 1/200 ou 1/250" était assez courant sur les reflex expert au temps de l'argentique. Sur un APS-C, la course de l'obturateur est 30% plus courte, à vitesse égale l'obturateur devrait déjà offrir une meilleure performance, d'au moins autant, soit 1/200" pour un obtu donné à 1/160"...tient, comme par hasard, c'est la synchro physique du D7D, vérifiée avec un flash manuel...qui était par ailleurs la synchro-X du D7, donc la limitation imposée par le constructeur est limite, parce que 1/125" (avec AS) c'est quand même celle d'un 7000i...un autre âge je crois.
Du plastique, du métal, du verre, beaucoup de piles en tout genre, et tout ça pour tâcher de faire des photos

Ce qui me ravit : que 2 et 2 font 4 (merci Ă M. Desproges)
Ce qui m'exaspère : avoir compté 22 atouts à la fin d'une partie de tarot

Ben, je suis bien d'accord sur le principe, sauf que Kilpatrick évoque des échanges avec les ingénieurs Minolta à l'époque du D7d... je doute que ces derniers se soient interdit une solution aussi simple si elle avait résolu le problème, non ?Fangio a écrit :EGr a écrit :Et vous avez lu la réponse du même David Kilpatrick, dans les commentaires sous le lien de Gally, au sujet de la vitesse max de l'obturateur ? à 1/8000ème, l'AS/SSS ne suivrait plus (si je comprends bien), créant des artefacts ?

Vu de l'extérieur, certainement... vu de l'intérieur (je pense plus à un problème hard que soft quand même
)... doit-on comprendre que tu ne crois pas aux explications de Kilpatrick ?

Oui, je suis d'accord aussi.
Et pour stabiliser un capteur plus gros, il faut 'juste' un moteur plus puissant, et ça on sait faire, ça doit surtout être une question de coût je crois.
C'est bien plus difficile de stabiliser une lentille qui doit peser 5 ou 6 capteurs !!!!
Attendons déjà l'annonce officielle du 12MP, ça enlèvera déjà tous les ragots sur celui-là , on pourra se concentrer sur l'autre
