Image Quality
If there is a single asterisk for this review, image quality would be it…you should know what you’re getting into when you buy this lens.
f/1.5: A smeary mess wide open, as if Vaseline has been smeared all over the front element. Nothing seems to actually be in focus, the bokeh is somehow buttery and jittery at the same time. I tested f1.5 long enough to know it’s not an aperture I will use often. It will be for dreamscape portraits ONLY.
f/1.7: The sweet spot for “character” shots. Focus is starting to tighten up (we can at least objectively say SOMETHING is in focus) and the background still retains that Helios-like swirl in spades. Flares are a little less prominent and contrast improves significantly over wide open.
f/2 to f/4: A middle zone of not great sharpness and not great defining character. Not sure I’d use this zone much to be honest.
f/4.5 to f/5.6: Things are getting much cleaner! Usable for “normal” type shots now.
Jump to f/8 and things are SHARP. Bokeh is looking respectable, and overall sharpness through the frame makes this seem like a completely different lens than the one we tested wide open.
the new XF16-55mmF2.8 II is a bit sharper and has a bit more contrast
the new XF16-55mmF2.8 has a bit better bokeh
the new XF16-55mmF2.8 has a bit better autofocus
the new XF16-55mmF2.8 as virtually no focus breathing (the old one was good there too, but not as good as the new one)
the new XF16-55mmF2.8 is lighter and smaller
the new XF16-55mmF2.8 has a de-clickable aperture ring
