You want a photo enlargement that is poster size? Convincing photo printing requires 100 pixels per inch. A 24x36 enlargement then is 2400 x 3600 pixels. However many digital cameras are 4:3 aspect ratio so you will need 2700 x 3600 pixels for full width, or about 10 Megapixel (non-interpolated). That is only if the original is perfectly framed, no cropping needed.
Traditionally, professional photographers use medium or large format film cameras for this purpose. Medium format is 2 inch film, various aspect ratios are available. However 35mm film can be scanned with good equipment at 2400 x 3600 pixels resolution.
You need to consider how the enlargement will be created. If it is to be computer printed, then all options are available. You need to confirm what your lab will need in order to make the print from film.
When i think of posters, it is as commercial advertising. In this case, the photo content is really a background element, and cropping is more critical issue than pixel count. Also printing will be by lithography which has its own special requirements for screening.

Digital SLRs like the Canon 400D , Nikon D200 or if you want to spend more a Canon 5D ,
depending on the size of the posters a medium format camera will be better but also more costly
