Historically, despite causing a stir at Photokina where it was first exhibited in 1992, the fundamentally flawed ECF in the A2E was considered very much a novelty. To their credit, Canon clawed back ECF credibility with the much improved retro-look EOS 50e in 1995 and again upped the ante in 1997 with the beefy mid-range EOS 3 — literally a compendium of stepped refinements and improvements under one cover. All well and good but ECF hasn't found entrenched, long-term favour among professionals, and it has been passed over in digital cameras in favour of tacked-on gimmicky functions and ever-more layers of complex technology. Having said that, if ECF EOS bodies appeal to a photographer, the EOS 50e or EOS 3 is a much better investment than the comparatively blighted A2E. Otherwise, pro-level bodies remain a wise investment in timeless quality and reliability.
