Sony FE 55mm F1.8 ZA Carl Zeiss Sonnar T* Lens compared to Sigma 50mm f1.4 DG HSM ART Lens on a Sony A7r

I've done a comparison test between these two high quality lenses, the Sony FE 55mm F1.8 ZA Carl Zeiss Sonnar T* and the Sigma 50mm f1.4 DG HSM ART Lens. If DxO are to be believed two of the best lenses ever made. Both were fitted to my Sony A7r, ISO 100, tripod mounted. These are out of camera jpgs.

I've included samples at two apertures above including wide open.

THE VERDICT

Both produce incredibly sharp results. And is one sharper than the other? Well yes, the Sigma is. But by a very, VERY small amount. You may not even see it on these resized web images. Is it important? no not at all. 

So which is the best? Well for a Sony e-mount system the Sony FE 55mm F1.8 ZA Carl Zeiss Sonnar T* of course. The Sigma is a Nikon fit and has to be used via an adapter with manual focus. There is a Sony a-mount version coming at some point however.

The Sigma is mainly for use on my Nikon Df and for occasional use on my other cameras. I was interested to see what it was like on my highest resolution camera. And indeed it turned in a spectacular performance. But then so did the Sony / Zeiss. DxO described it as the best AF lens they have ever tested and I'm not going to argue with that. 

So if you are planning to buy either, prepare to pick your jaw off the floor and recover your socks because this is pretty much the best you can get. (Unless you have a few £1000's for the Zeiss Otus's that is!!

As a full-time photographer I make my living from selling images on Stock Photography sites. Writing this blog and doing the comparison tests takes time away from that and earns me very little. If you find what you read here of interest, then you can help me to fund the gear I buy to review, by clicking on the adsense banners, donating and / or buying your gear from the affiliate links. You don't pay any extra, I get a small commission. 

Previously I was posting on the free, Blogger platform, but this site, with it's greatly increased functionality, costs me money and the more it expands, the more it will cost.  If I can get THE SOUNDIMAGEPLUS BLOG economically viable, then I will be able to review a lot more gear and extend and expand those reviews. Running a blog these days that competes with the best out there requires a lot of time and effort and is clsoe to a full-time job. This means that I'm neglecting other work to put that time in. It is my intention to turn this into a much more comprehensive review and user experience site and I can only do that if I can get it to generate more income. 

This site, like much of the internet, has free content and like much of the internet is funded by advertising and donations. I realise that not everybody likes advertising, but without it many of our favourite sites would have to resort to charging for what they do. Google, Facebook and all the other social networks sites remain free because of that advertising. I try to make the ads as unobtrusive as possible and I certainly won't be installing any of those annoying 'flickering' or video boxes. Below are some links to Amazon products relevant to each post and I will continue to put them at the end of the articles. 

There is an interesting article on the BBC website HERE, which deals with many of the issues above.

Many Thanks
