Further readings for the Sony FE Carl Zeiss Vario-Tessar T* 24-70mm F4 ZA OSS
To provide photographers with a broader perspective about mobiles, lenses and cameras, here are links to articles, reviews, and analyses of photographic equipment produced by DxOMark, renown websites, magazines or blogs.
We’ve tested the image quality of the 24-Mpix Sony A6000 with over 23 zoom and prime lenses. Read on to find out which of those models perform best with Sony’s current top-of-the-line APS-C mirrorless model.
We’ve analyzed the image quality of the 20-Mpix Sony A5000 with over 20 zooms and primes. Read on to find out which of those models you should be using with Sony’s smallest and lightest mirrorless model.
At less than half the price of the marginally wider, slightly faster Zeiss 24-70mm f4, this in-house Sony model looks like a tempting alternative, but can it meet the demands of the high-resolution sensor in the A7R? Read on to find out.
One of the four lenses announced at the time of the introduction of the Sony A7 and A7R, this high-grade G-series telephoto zoom looks like a promising addition to the range. Read on to find out how well it performs on the 36-Mpix Sony A7R.
On the optical point of view the two couples are pretty good. But the Sony A7R sensor performance brings more information capacity, therefore a higher overall score.

Re: measurements of FE 24-70mm F4 ZA OSS (SEL2470Z)
Hi, Thank you for contacting us. Unfortunately, it is quite touchy to explain the reason of the "inconsistency " you're referring to, but it is safe to say that it may be caused by a slight sample default. I am glad to inform you that the Sony FE 28-70mm is in lab, and its review should be available very soon. The lens results for the Sony A7 should follow, so stay tuned!
Thank you for the SEL2470Z review. I would like to ask when SEL1670Z review will be available. This item is even not in the list of Sony lenses. So I had to post my question here. The comparison between 1670Z and 2470Z would be the major interest among a large group of NEX APS-C users. Me too, who understood that I will transfer to FF in the future, would like to know if I should start preparing for the FF right now. Thank you.
For this lens the best apertures are f/5.6, f/8 and f/11 for every focal. This performance depends on optical design. But usually it is a bit more difficult to design a lens that achieves its best performance at the wider aperture. At 70mm f/8, one point is slightly lower than f/11 (5% lower) but it is worth nothing that these 2 apertures remain the best as for other focals. Best regards.
