lorenzo de medici: Rishi is a fine photographer, and optically the lens appears to be excellent. I'm just not a fan of close up portraits, or wide angle shots with a shallow DOF. So while I commend Sigma for producing a unique product, it's not one that I would buy or use.
@Rishi: I too like wide angle portraiture for the reason you mentioned. But I would not shoot with wider than 35mm though - 24 mm looks too wide for me, but of course it is a personal preference. And I feel that wider angle portraits make female subjects look cuter (instead of model-like) and gives overall an intimate feel. For those interested, here is a flickr group for portraits shot with 35mm lens on full frame (not my photos): https://www.flickr.com/groups/35mmlensportraits/pool/
supersport100: Too bad, my Canon 5D III can't do it. It's 2015 and the established manufacturers never got it done. The most comprehensive overall system don't help if the eyes are out of focus. Sony must have seen this lack of competence and saw this as a huge chance.
Focus on the eyes, sounds so basic.
Hey Canon, can you now start learning from the competition, please?

"Auto AF-Area Select: Finds the face even if it's not in the center and even if it's not the closest thing. (Actual view through viewfinder; pretty sharp, eh?) I didn't select this AF area, the camera did, and it tracks all around the finder as the subject moves.
When the face is close enough, it is smart enough to focus on the closest eye all by itself, which is perfect!
It even thinks this smart and this fast if I'm behind my subject. Here the D810 sees and focusses on the nearest eyelash:"

"Ryan plays a flight simulator(photo)See? Dead-on AF in dim light at f/1.4. The AF system is smart enough to find that eye and nail it.
AF Auto-Area Select uses face recognition to find the subject's nearest eye and focus on it automatically. It really works, and will find the correct eye on which to focus and ignore closer objects that are covered by the AF sensors.
Here's a typical example of how the Auto AF-Area select sees right past a distracting, closer, brighter central foreground object and focuses on the subject's eye instead, all by itself:(photo)This is a huge help for people and family pictures. Instead of having to stop and jockey the AF area selector manually, I can let the camera find the eyes and take care of the focus so I can concentrate on my subject.
(photo)Crop from above.Again, focussed automatically right on the eyes, not bad at f/1.4 at ISO 1,800. My D750 found the eyes, focussed, and I shot. Easy!"
AFAIK, both D810 and D750 has eye detection AF. Don't know about D610 though. No DX sensor Nikon has it.
Now use proper noise reduction and sharpening to the Tulip shot and print it 12x8 inch or larger, and let us know if the outputs are useable. May be I am demanding too much, but the shot itself is beautiful and begs to be printed.
Didn't Sony just missed the opportunity to have exclusive Zeiss AF lenses for their mount? They could share their AF specifications to Zeiss and could have Af lenses for E mount. As both Nikon and Canon do not have AF Zeiss lenses for their mounts, this could be a huge advantage for Sony.
£1499.99 / €1459!!!? I dont even find 24-70mm range useful, as an f4 lens it could be at least 85mm on the long end IMO to be useful for portraits.
nalex: 24MP full-frame CMOS Sensor with on-chip phase detection AFAND...Fixed-mirror design SLT
How dumb is it? Sony put phase detectors ON SENSOR and put semi-transparent mirror IN FRONT OF IT.Why not mirrorless then?
I was thinking the exact saming thing. Or are we missing something?
IcyVeins: Great job Canon. You've made your final Rebel DSLR and now you're killing off your customers so that they don't switch over to Sony and Nikon once you've closed up shot on Rebels for good.
@ ImageInstyle: If it was made in Japan, it would be radioactive :)
Why don't you mention shutter speed as well as f number? Otherwise we have to download the full sized photo and check the shutter speed.
skin tone looks very beautiful in this photo!
