Introduction | New pixel technologies vs. pixel pitch reduction | SNR and image quality evolution | Conclusion

In summary, DSLR sensor technology has made significant advances over the past several years, with full-frame sensors outpacing the progress of APS-C sensors. DxOMark Measurements show that advances in RAW conversion technology have compensated for the increase in SNR brought about by the proliferation of smaller, less light-sensitive pixels in DSLRs, with the result that today’s high-resolution cameras produce higher-quality images overall than low-resolution cameras when viewed or printed under the same conditions.
