Very good performer on full frame


  • Well balanced on A7 cameras
  • Weather sealed
  • Very sharp
  • Smoother bokeh than most 50/55mm lens
  • Silent focusing


  • Pricey
  • Some sample variations
  • Minimal focusing distance a bit too long
  • Fragile paint
  • Heard of an internal motor only retain by glue

This review is about Sony Zeiss 55mm f/1,8 on full frame. I never tried it on APS-C because I already had the Sigma 56mm f/1,4. I don't know why I'm forced to wrote in the APS-C section.

I used a few vintage and adapted standard lenses on my A7 before finally getting this one. Short story is I should have bought it sooner.

The 55mm f/1,8 is well balanced on the A7 serie. Only the original hood makes it longer. Optical quality is very good. It is simple and efficient. Sharpness is very good from wide open and perfect stopped down. I really like the bokeh. I never spotted any obvious onion rings and I'd say it has overall smoother background than most 50/55mm lens especially given it's only f/1,8 aperture.

f/1,8 + 55mm focal lenght on full frame gives enables you to get good subject separation if you want to. The lens is fully usable wide open and it's character is pleasant.

The lens is definitely not cheap but it is a high end standard, better than a consumer standard like my Nikon 50mm f/1,8 G for instance.
From my experience, Sony's regular 50mm f/1,8 could be very good but sample variations were so high I didn't want to play the lottery anymore. There may be some variations with the Sony Zeiss too but you control quality is obviously tighter.

I only regret that the paint is fragile and I worry a bit about an internal motor only retained by glue. But I keep my fingers crossed, my sample has been used and abused and still work like a charm.
