Noise

Amateur Photographer - - Testbench -

At its base set­ting of ISO 64, the Z 7 ren­ders our stu­dio test scene with an ex­tra­or­di­nary level of de­tail, vi­brant colour, and barely any vis­i­ble noise. But what’s equally re­mark­able is how well this holds to­gether as the sen­si­tiv­ity is raised; ISO 1600 im­ages are very nearly as good. The finest de­tail starts to blur at ISO 3200 when viewed on the pixel level, but this prob­a­bly won’t be ev­i­dent ex­cept in prints of A3 or larger. Even the high­est stan­dard sen­si­tiv­ity of ISO 25,600 is sur­pris­ingly us­able. How­ever the ex­tended higher set­tings are dis­tinctly mar­ginal, and at the mo­ment Adobe soft­ware doesn’t even recog­nise ISO 102,400.
