I am trying to compose a detail shot where I want to get as much background blur as possible. I am using Sony a6500 camera (APSC 1.5x crop factor body). I am considering two lenses:
Sigma 30mm f/1.4 (native APSC lens)
vintage Minolta 50mm f/1.8 full frame lens (with adapter for Sony E mount)
But no one seems to be addressing the effect that this might have on bokeh and other artistic values of the images.
I can get some pretty decent bokeh with my Sigma lens, especially on detail shots, but the bokeh I can get with the Minolta lens is also just as good, sometimes better, when I use that Minolta lens on a "full frame" 35mm film camera.
So I am trying to figure out:
- which lens is going to give the most bokeh on a 1.5x crop sensor body?
Also, recognizing that the two lenses are different full frame equivalent focal lengths for this body (the 50mm becomes a 75mm equilvalent on the Sony a6500), if I swapped the 30mm Sigma f/1.4 for the 56mm Sigma f/1.4;
- would the 56mm f/1.4 Sigma or the 50mm f/1.8 Minolta give more bokeh on the Sony a6500 body?
