Cross platform equivalency
4 months ago

FF > MF that is.

Yes this will concern a rumored Canon camera, not an actual one (at least for the moment).

I am pretty comfortable in my understanding that more MPs per given area results in more detail.

Let's say this rumored camera, casually referred to on this forum as the High Resolution Monster, has 51 MPs just like the Pentax 645Z.

Those same number of MPs will be laid out on .79x less area on Canon's FF sensor as opposed the Pentax sensor.

I have admitted in the past that I am fuzzy on cross platform equivalency but until now I have not been interested in anything but FF. The Pentax 645Z may change that.

Noise and DR aside, which set of 51 MPs will produce more detail, less detail or the same detail in the respective systems all other things being equal?

GB mentioned large pixel blur the other day so I am interested if that concept applies here in any way since the pixels on the Pentax sensor will be larger.

Anyone not familiar with the Pentax 645Z can catch up here:

The pros of the 645Z, $8499, 51 MPs. on a sensor larger than FF, weather sealed, 25 cross-type AF points, and wait for it.............. articulating LCD.

The cons: 3 fps.

Lenses for the system mostly look reasonably priced although you won't find any pity-fifty pricing. The MF>FF crop factor is .79 according to DPR.
