Hello together,
a couple of days ago I used my old Tamron lens on my Sony A7 II, I turned off the Automatic APS-C detection on the menu to still be able to use the complete image sensor area of the camera.
Using a Commlite EF to E-Mount adapter the autofocus speed is okay, although it's not as fast or reliable as on the Canon 70-200 f4.0 I'm using, too.
I was positively suprised about the sharpness of the lens, even when shooting wide open. Of course there is a large black area on the outer edges of the sensor but depending on the use case this might not matter much, which I would like to show you here. Lacking a tripod that niht I had to put the camera down on the ground on the camera bag.
It's 15 seconds exposure at f4.0 with ISO6400. Post processing involved:
+1 EV
more contrast
lights up, shadows down
white up, black down
some clarity and a slightly steeper graduation curve (30,15,-15,-15)
a little bit of sharpening and no noise reduction
...
That's it:
