Sigma 12-24mm Mk II has landed

I ordered mine today, should arrive Tuesday. Can't wait to see what 12mm looks like on FF.

The main changes over the Mk I are to the glass - four FLD elements (Sigma's version of fluorite) instead of one, which bodes well for good IQ, provided I get a good copy!

Insanely wide.

One of my favourite lenses, I'll definitely upgrade.

Please share sample pictures. I would love to get my hands on this one as well.

What is the field of view at 12mm on a FF camera?

122 degrees diagonal, or 112.6 deg v & 90 deg h.

I am very much looking forward to your review as this will probably be my next lens ... especially interesting would be the corner sharpness at 12mm and the f4.0 - f8.0  range compared to the previous one ...

I am very thankful for every review of someone who already has one ...

I have the first version of this lens. I was about to send it off for calibration, but may hold off and put the money towards this. I'll be watching with interest, for reviews.

There would probably be some reviews by sites with measurements and sample photos before I get to buy the lens, but I'd be happy to upload side-by-side comparisons once I buy the lens.

Usually I trade-in lenses as part of upgrades, but in this case a friend wants to buy the lens, so unless he folds at the last moment, I would be able to shoot with both at the same time.

The lens arrived this morning and I've taken a few field (non-scientific) test shots of the view outside my window. Here are my initial observations.

Centre at 24mm and f5.6 not quite as sharp as my 24-105mm at 24mm / f5.6. At f8 and f11, there really isn't much to choose between the two. The 24-105mm frames slightly tighter so either it doesn't quite reach down to 24mm or the Sigma doesn't quite reach up to 24mm.

Borders and corners very good at all apertures - at least as good as the 24-105mm. This is a pleasant surprise.

Resolution appears to be consistent from 12mm through to 24mm.

I've so far failed to induce any CA. It's a sunny day here so I tried sun reflections off shiny paintwork. No discernible CA. Another pleasant surprise.

I thought to begin with that the lens was back-focusing but it isn't. Being as wide-angle as it is, the difference between 2 metres and infinity on the focus ring is just a few millimetres of rotation so the distance window displays infinity when focusing on anything more than a few metres away. It just goes to show how deep the depth of field is on a lens like this.

Build quality excellent. Smooth, dry action to the zoom and focus rings (very similar firmness and feel to the 24-105mm).

I'll post some photos when I've had a chance to do a proper outdoor shoot.

Incidentally, I bought it from Warehouse Express here in the UK but I can't find anywhere else in any country that is advertising it yet.

I have the first gen version of this lens - needed something for a trip to Hawaii and Mark II wasn't out.  Not the sharpest, but some interesting pictures.  Here is one at 12mm

It's a very good lens. I really want people to start posting in depth reviews. It seems strange to me that there aren't many about. If it was a Canon lens, the web would be littered with them by now :(

Corner sharpness of that lens is really bad! Just as well use a 14mm lens with good corner sharpness, like the cheaper Samyang.

Well it was shot at f/7.1 I would have also liked to see some shots at f/11 and f/16 to determine sharpness in the corners.
