Sharpness: Sony Fe 55 f1.8 vs Samyang 50 f1.4 vs Minolta MC 50 f1.4

1 vs vs2 vs3


We´ll, dont know how satisfied i am with this “test”. My guess is that the Sony Fe 55 missed focus slightly on the F8 shot (The branch in front of the sign is more in focus on the Sony shot). The Minolta has no doubt the best center sharpness at f8, between these shots atleast.

Apart from that the Sony Fe 55mm f1.8 win on all fronts (wideopen). We´ll perhaps not shortest DOF in the first shot, the other 2 are f1.4 the Sony beeing f1.8.

As far as sharpness wideopen goes, the Sony wins. Contrast seems pretty much on pair with the Samyang (but the Sony is better 🙂 ), the Minolta lacks pretty heavy in that area. Wideopen the Minolta also got that Strange “Vail”. Same milky layer as the Canon 50mm f1.8 has wideopen if you ever used that lens.

The f1.4 of the other blurs the background just slightly more than the Sony, if you look at the numbers in the background the are more obvious, partly because of the better contrast of the Sony but also due to the longer dof of the Sony.

(its says f1.8~2 because the other 2 dont have an f stop for f1.8 so its somewhere between f1.8 and f2)

Thats it for now 🙂

Some CA in the last pic, both Purple and green, but nothing crazy to whine about.

Love the colors and beokeh of this lens more and more 🙂

And the colors of the A7r aswell ofcourse, colors are great with the other 2 lenses i own. Samyang 12mm f2.8 & Sony FE 28mm f2.

This thing is sharp (Look at the crop of my grand-mas eye! 2nd pic 🙂 ! Great bokeh and colors. Some purple CA and

some green aswell, take a look at the text on the “bottle”, but still, it´s well under control.

My patience ran out today, my ebay adapter is running late. So i taped my Minolta 50mm to the Konica mount i got last week, it turned out alright 🙂

Really want the real adapter now, this lens seem to offer ALOT of bang for the buck. (140Usd, including customs/shipment, 115Us without :/)

Great sharpness, CA is well controled and nice bokeh! 🙂
