Crop Sensor is an Upgrade Path to Full Frame?
Posted: Fri 09 Jan 2015, 00:57
I read this post on DPReview with interest as both "fallacies" referred to in the article have applied to me. I have always had a crop sensor DSLR and assumed at some stage that I would move on to full frame and bought lenses with that intention, but it never happened. When I was ready to upgrade from a Canon 400D, the 7D seemed a better all round camera than the 5DII, so I bought that instead. Had the 5DIII been available at the time, I probably would have opted for it, but by the time Canon launched it I was happy with the 7D and no longer wanted to invest in more DSLR kit. Canon's conservative approach to upgrading its sensor technology was also a factor in my decision and the 5DIII did not offer enough of an upgrade to justify the purchase.
What I do question is how useful a full frame sensor really is these days given recent technical advances. Yes, there are issues with increased DOF with a smaller sensor and often high ISO performance is not quite as good, but most manufacturers who introduce new systems have implemented smaller sensors. Fuji, Leica and Samsung have all opted for APS-C, as did Canon with its mirrorless EOS-M mount. Olympus and Panasonic went even smaller with the 4/3 sensor, with the Nikon 1 and Pentax Q systems having the tiniest sensors of any interchangeable lens cameras. Only Sony bucked the trend by introducing the A7 range with full frame, but still has an APS-C system as well. Judging by how well the new Samsung NX1 performs, the difference between APS-C and full frame is narrowing. The trade-off between light gathering capability and smaller/lighter camera gear is not such an issue as it once was.
