Az 50D mostani bejelentesen nem lennek meglepodve. Asszem a pixinfos topikban a 40D bejelentesekor mar hitetlenkedtem, hogy hogyan fog masfel evig kitartani a kozepkategoriaban, de az alacsony ara miatt azert nagyon fogyott. Viszont a Canonnal is biztosan tudnak a D90 erkezeserol es nem akarhatjak, hogy annak is alasorolodjon a kozepkategorias vazuk.
A FF erzekelo terulete valamivel tobb mint duplaja az APS-C-nek (hogy mennyivel az attol fugg, hogy a Canon, vagy a tobbiek erzekelojet nezzuk), igy a "hatar" nem annyira rossz sacc (mondhatott volna 35-ot is).
Tudom, hogy nem stimmelnek, ezek csak az általam feltételezett határok... :) nem matematikai módszerekkel számoltam. (jobban örülnék valós 10Mpixeles X3 szerű szenzornak, ez is igaz...)
És azon gondolkoztál már, hogy milyen jól mutat a dobozon a bűvös 15 MP szám, az egyszeri embernek csak az tűnik majd fel, hogy "jé, több mint azon a nagy Nikonon (D700), és még olcsóbb is"? Nehogy azt higgyük már, hogy a világ DSLR vásárlóinak a 75%-a akár picit is gondolkodik vétel előtt azon, hogy a fél internetet átbányássza, melyik gép milyen. Bemegy a bótba, előveszi a credit card-ot, oszt megveszi azt, amelyikre a nagy számok vannak írva...
Azért van akinek jól jön a nagyobb felbontás, mint pl. nekem... igaz csak 40D-m van, de sokszor elég nagy méretű nagyításokat készítek (90x120cm és hasonlók). Amúgy is APS-C-n 15-16Mpixel-t tartok értelmes határnak... (FullFrame-n pedig kb. 30Mpixel-t).
Szerintem a Pentax nem igazán vetélytársa a Canonnak. Az Eos-ok fő riválisa a Nikon, a többiek (Pentax, Sony, Olympus, Sigma, Fuji, Panasonic, Samsung, stb) együttvéve a piac kevesebb, mint egyharmadán osztoznak, alig-alig befolyásolva a két legnagyobb gyártó fejlesztéseit. Ami a marketinget illeti, egy százezres nagyságrendű gépnél már nem feltétlenül elődleges szempont a felbontás. Ráadásul a gyártóknak feltételezhetően hosszabb távú stratégiája is van, így gondosan ügyelnek arra, hogy soha ne ugorjanak túl nagyot, mindig csak kisebb lépésekben fejlesszenek. Ha esetleg a Canon piacra dobna egy 15mp-es 50D-t, akkor a vásárlók joggal várnának majd el egy 20mp-es 60D-t és így tovább...
Mar honapokkal ezelott lehetett olvasni, hogy a ciklusok rovidulni fognak es a gyartok megkezdtek az atallast az 1 eves ciklusra. Kisebb fejlesztesek jonnek, de gyakrabban, es gyorsabb areses. Azt, hogy mikortol, azt nem irtak.
Hm, mókásak ezek a hírek... :) A Canon már emberemlékezet óta másfél évente hozza ki az új modelljeit a kétszámjegyű szegmensben. Így az 50D-t 2009 februárjában fogják bejelenteni. Valszeg 12 mp-es lesz, minta 450D... semmi sem indokol 15mp-t. Ami korábbra várható az az 5D utódja, remélhetőleg idén ősszel...
Canon’s China website has published specifications for the 50D in its public webspace. Although the info is not on the front page of the site yet, it is accessible to anyone. Here is the link (update: it’s down, but this one is still live for the moment 11:51p.m. ET). I’ve set forth the relevant translated specs and info below. Please note that the original specs listed here listed in-body IS as a feature. The translation was wrong and the feature has been removed from the spec list below. The specs referenced the advantages and compatibility with lens-based IS instead.
