Lenses and Optics Practical Use of Field Curvature Graphs – the 50mm Primes
In my last two posts (1,2), I’ve been using field curvature graphs to look at how lenses behave as you stop them down. It’s been a fairly limited data set; basically 35mm prime lenses and some zooms at 35mm. I’m going to keep going with this topic and today look at a different focal length (50mm).…
