Lens Review – Sony Zeiss 16-35mm f/4 FE

Focus Sponsor Sony Australia lent the Focus group the only pre-production model of the Sony Zeiss 16-35mm f/4 FE in Australia. Images with this lens were captured by John Armytage using his A7R and the raw files were sent to gear nerd Chris Wiewiora for analysis. This is what Chris found from his lens performance review. 


John Armytage asked me to review the unreleased Sony/Zeiss (Zony) 16-35mm f/4 FE that he has been using. Although it is tricky to make a proper assessment from just viewing a few brick wall RAW files, I can get a general idea of its performance.

This lens is designed for the Sony Full Frame E-Mount for cameras such as the Sony A7, A7r and A7s. The main specs that stand out are the 518g weight, compact size (for an ultra wide angle retrofocus lens design) and great build quality, with an all metal body (including the zoom and focus ring). My benchmark was the Canon EF 16-35mm f/4L, as it’s the best performing 16-35mm released at the moment in my opinion.

From the lovely brick wall shots John took, the corner performance is impressive, especially at the wide end. Its peak performance seems to be around the mid focal range but the wide end is surprisingly good comparatively. The corners at 35mm look okay but overall sharpness starts to suffer. Compared to the Nikon 16-35mm f/4, Nikon 17-35mm f/2.8, Canon 17-40mm f/4L and Canon 16-35mm f/2.8L performance looks better. Now compared to the Canon 16-35mm f/4 which is a superb lens, it’s much harder to evaluate, as they are so similar. From the full res images I have seen taken with the Canon @ 16mm on the A7R, the Sony looks on par if not better. I haven’t seen any images taken at other focal lengths, so I can’t make that judgment but they have similar IQ characteristics throughout the focal range.

The distortion looks reasonable at 16mm relative to the rest but although I couldn’t see for myself, I have read that past 24mm there is a bit of pincushion distortion. I couldn’t see any field curvature at 16mm and 24mm but there were hints of it around 35mm. Thankfully it has a great sun star, with nice thin diffraction rays at f/22. There is a bit of chromatic aberration but CA is an easy fix in ACR and Lightroom. Vignetting doesn’t look bad but due to the small 72mm filter thread, you don’t want to stack too many filters and I’d recommend using a wide angle adapter.Here are some 100% crops with no sharpening applied except for ACR standard (25).

The first image in the dropbox folder shows the top right corner of the Sony and the last image is the bottom right corner taken with the Nikon 17-35mm f/2.8 @f11 and D800E. The first image is at 16mm f/8, then 16mm f/13 and then 24mm and 35mm at f/8 and f/13. The second image is the same but the centre of the image at 100%. The final image is the top left corner of the Sony @ 16mm f/8 and the bottom is with the Canon 16-35mm FE @ 16mm f/11 comparing the corner softness. A single point curves adjustment was added to the Sony to correct the brightness. Overall I think it’s a great zoom lens and I’m relieved the corners are much better than the Sony 24-70mm FE, which was a bit disappointing. It is comparable to the Canon EF 16-35mm f/4L in my opinion but smaller, lighter and no need for a metabones adapter.

Thank you Sony Australia for lending the focus group the only pre-production lens in Australia for testing.

Shortly after writing the review, I ordered my own copy and it arrived today. My first physical impression of the lens is how light and compact it is. It nearly feels like the lens is hollow but most of all how well built it is. The all metal body including focus and zoom ring blends perfectly with the A7 range of cameras but also increases the durability of the lens. I’m also impressed with the nice resistance in the focus run but especially the zoom ring. Hopefully this means the lens has quality seals for when the front element extends when zooming out towards 16mm.
