Re: Equivalence - its use and abuse

The best way to compare two cameras and lenses of different sensor size is to look at equivalence. Based on this, the two combinations are virtually the same. Wide open, the Sony will offer the same depth of field as the Fuji at f2.8, the Fuji at iso 200 will look like the Sony at iso 400 etc. It will also have similar DR once you equalise depth of field.

The Fuji will be cheaper and have better build and a much better evf, the Sony will offer more DR at iso 200 and 100, the Sony will offer slightly greater reach and AF.

On that basis, if he were to never to buy another camera or lens. It doesn’t really matter at all. That’s what equivalence is all about.

However, if he does want to expand his shooting, it alll depends on what direction he wants to take. The Sony has f1.4 primes that offer the ultimate in shallow depth of field. The Fuji has compact lenses like the 55-200 for which Sony has no equivalent, and (for now) goes longer with the 100-400.

in terms of other bodies, a Sony system will allow him to go with a high megapixel body like the a7r series later. However, with Fuji he could get the x-e3 to use when travelling light.
