Definir el uso principal que se le dará a la cámara, y las necesidades técnicas o de orden práctico vinculadas a la propia actividad, que determinan la elección posible. NO incluir entre esas el costo o la posibilidad de conseguirla en Argentina.
El uso principal que he de darle a Mi Cámara Digital Ideal será para fotografías de deporte a altas velocidades al aire libre y en interiores, y por otro lado para producciones artísticas en estudio. Lo necesario será un equipo versátil, que tenga la posibilidad de sacar varias fotografías en serie a altas velocidades, por ende la memoria debe ser bastante rápida. Por otro lado es menester contar con un flash que permita realizar efectos de congelado simultáneos y pueda ser utilizado también en estudio como flash principal o de relleno. El lente a escoger debe tener estabilizador de imagen ya que va a ser empleada sin trípode en ciertas ocasiones, como también debe ser bastante luminoso (1.8 – 2.8 de apertura máxima) para responder de manera satisfactoria en situaciones de poca luz.
Buscar 2 o 3 opciones de equipos que cumplen con esos requisitos y compararlos usando la herramienta "Compare" de DPReview.
Buscar y adjuntar las especificaciones técnicas del fabricante de cada cámara.

FLASH SPEEDLITE 580EX II
Buscar (o realizar) y adjuntar 5 imágenes o más de cada cámara, de buena resolución (mas de 2000 px en X o Y) y en escenas dificiles (nocturnas, poca luz, movimiento, etc.) o de los puntos "fuertes" en relación al objetivo definido en 1.
EOS 1D Mark III
Concluir en base a los datos recopilados cual sería la mejor opción para ustedes, y justificar brevemente (2000 caracteres máximo)
En Conclusión luego de una investigación exhaustiva sobre las aplicaciones, ventajas y desventajas de ambos modelos llegue a la conclusión que la cámara que mas se adapta a mis necesidades como fotógrafa de deportes a alta velocidad tanto en interiores, como en exteriores y también que se amolde a fotografía de estudio artística es el modelo de CANON EOS-1 DX.
Esta cámara posee un total de 18.1 megapíxeles efectivos, menos que la otra opción elegida para la comparación, pero por otro lado, es mucho mas versátil a la hora de guardar los archivos, nos permite por ejemplo no guardar solo el mayor formato en jpeg junto a su versión RAW, sino que también nos permite guardar jpeg de menor calidad junto a su respectivo RAW en caso de que no tengamos capacidad suficiente.
El modelo elegido posee gran velocidad de almacenamiento, llega a tomar 14 fotografías por segundo, funcionando esa característica del equipo con una tarjeta de memoria superior a clase 10 pueden lograrse muy buenos resultados en competiciones o carreras. Tambien cabe destacar la necesidad de tener un Flash con gran potencia como el FLASH SPEEDLITE 580EX II cuyo rendimiento he probado y funciona de manera perfecta en competencias de skate por ejemplo y tambien en shows nocturnos.
