Quote from: BJL on February 18, 2018, 05:18:54 pm Ray, you have in a rather quirky way illustrated my second point, on which we all seem to agree: if and when the best results in the larger format involve using a sufficiently low aperture ratio, then it is harder or impossible to get those results in a smaller format. Of course, if the answer for the user of 4/3" format is "yes, often enough", the next question is whether the step to a good 24x16mm format system is enough to scratch those itches, or if instead the jump to 36x24mm or 44x33mm or even beyond is worthwhile. more visible fine detail, in the sense of more "lines per picture height" of resolution? (Achieved if the sensor and the lens and aperture choice combine provide that - not true when the current format is already constrained by DOF and diffraction trade-offs.) less visible shadow noise and finer tonal gradations in the deep shadows? (I agree mostly with Guillermo Luijk that a larger sensor does not give finer tonal gradations other than in the deep shadows, because elsewhere, the gradations and local SNR ratio in the smaller ILC formats are already far finer than the eye can distinguish.) larger apertures than the current format allows? (For more OOF blurring, less noise at high enough shutter speeds, etc.) Would some of the images from one's current format, when displayed and viewed as one wishes, benefit from Given the extra cost and weight involved in using a larger format, especially when equipped with the lenses that offer those large apertures and related advantages in low light/high shutter speed situations, some questions to ask are: Ray, you have in a rather quirky way illustrated my second point, on which we all seem to agree: if and when the best results in the larger format involve using a sufficiently low aperture ratio, then it is harder or impossible to get those results in a smaller format. ![]()
