Your reflex is a funnel!
In these weeks, thanks or due to the challenging SLR Sigma SD15, I’m brushing off the old notions of photography, dating back to the late 90s, on film SLR. I’m focusing in particular on the theme of sharpness, or rather the resolving power.
I then dived into the web, still a great resource, where in some personal blogs, and especially old forums of photography enthusiasts a bit ‘old school, I found the typical old discussions about the not importance of megapixels, the influence of the format and the related theme of the most demanding APS-C sensors, etc. In short, the usual discussions by photographers between the pro and the passionate fussy.
The sacred Grail of photography: definition.
And finally here is the object of my research, the theme of the definition of a photographic system, SLR or mirrorless that is, and of its scrupulous measurement.
The reality in which we live is analogical, composed of infinite details, definable with the symbol (infinite). In systems, it is usual to indicate in lpm, that is, the number of lines per millimeter that a photographic lens is able to distinguish.
