SONY A7R + SIGMA 50mm f/1.4 ART LENS

It's huge, it's heavy and it's taken me a while to work up to trying it. But I had three Weetabix for breakfast, took a deep breath and ventured out with my Sony A7r + Battery Grip + Sigma 50mm f/1.4 ART lens to see if my suspicions were correct. That this would be close to the best quality it's possible to get with a digital camera this side of medium format. Was I right, or did I just return home with a bad back and a sense of anti climax? Read what happened after the camera porn.

This combination certainly gives the idea that Mirrorless / CSC / E.V.I.L cameras have a size and weight advantage a bit of a kicking. OK it is a DSLR lens, but I had no Mirrorless Inferiority Complex walking around a stately home with this thing. I also had a quiet inner grin when I walked past some guy swanning around with a Canon + zoom and seeing his eyes pop out of his head when he clocked this.

If you haven't seen the Sigma 50mm f/1.4 ART lens, then be prepared for a bit of shock. It is HUGE. With 815g of metal and glass it's bigger than most zooms and one of the heaviest lenses I've ever carried around. You'll not be surprised to learn that I didn't take anything else with me.

Focusing was also a bit of a pain, since the lens, the Metabones adapter and the camera didn't seem to see eye to eye about what they were all supposed to be doing. But I managed somehow and hoped I'd got some decent shots. 

So back at Soundimageplus HQ, I got the pictures up on the screen and suddenly all was forgiven. This lens is simply amazing. Sensationally sharp, Bokeh that made even me think there was a point to it and a genuinely beautiful rendering. It used every one of those 36MP to create almost forensically sharp, hyper-realistic images with extraordinary detail and resolution.

It's certainly more lens than I'll ever need and while today was supposed to be a one-off, I may well be tempted to give this another go at some point. I went somewhere I have a lot of pictures of, plus the weather wasn't great, so it was an ideal testing scenario. But the thought of this combination in great light with scenic landscape in front of me makes my mouth water (and my back groan!!)

Here are a few samples with 100% blowups.

So seriously impressive. And yes this is the sharpest lens I've ever owned.

But, in terms of going out and using it, I doubt I'll be carrying it around much on my stock shooting trips. The manual focusing is just so slow and fiddly that it certainly wasn't a pleasure to use. It's a different matter when it's mounted on my Nikon DF. Yes it's still big and heavy but it has AF (and pretty quick AF as well) so it's a much more usable lens.

For tripod mounted video and for studio type work where i've got plenty of time to set up however it's a different story. This is a special lens and under the right circumstances is just what's requires. I'm also planning to use it as my 'reference' lens. Since via adapters it can be used on virtually all my cameras (and I'm hoping those Chinese factories who make every kind of adapter possible will eventually get round to a Nikon to Leica T one) so it's going to be used for that. I'm going to be putting together a Nikon Df / Sony A7r comparison and I'll be using it for that.

And of course there is the question of how it compares to the Sony FE 55mm F1.8 ZA Carl Zeiss Sonnar T* Lens. Now that's going to be the subject of a whole post which should be arriving sometime next week. (Update - That comparison is done and is HERE)  In use terms, the Sony / Zeiss is the one I'll take out with me for my stock shooting. It's so much lighter and smaller and almost as fast, as well as being an AF lens.

So as far as my Sony A7r is concerned the Sigma 50mm f/1.4 ART is a 'special occasion' lens. And special is an VERY appropriate word for it.

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 close 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
