Probably the best camera in the world for some scenarios

Thanks, I get the impression that the Sigmas are a sort of best kept secret.   My 5 star review will probably not cut much ice on its own although was perhaps an effort to highlight their brilliance in the hope more enthusiasts might find them, although at the same time I would not want to mislead someone looking for an all rounder.

If you look at dpreviews own recommendations it does not get a mention although that seems to be the case on all other review sites.  Odd one really.

I haven't reviewed any of the dp Quattros even though I've owned all 4 of them. Definitely wouldn't give any of them 5 stars, even if grading them only within their relatively small "comfort zones".

I made great landscape images with all of them but some of the magic was lost with the new sensor. And I bashed some of the "Never Quattro" guys here on the forum back in the day, before I came to see their point.

I was initially turned off by the Quattro body shape and feel but eventually came to like it well enough. I dislike the body size. I don't expect them to be as small as Fuji and Ricoh APS-C compacts, but they still seem unnecessarily unwieldy. I hope Sigma can make the next generation more compact, more along the lines of the original DP. Also 20MP full frame X3 would be fine with me.

Thanks.  I have not tried the earlier versions although if you dig into the reviews, certainly, like you, some people speak highly of them.  With Sigma I get the impression that if they had massive R and D budgets for their cameras then they could probably produce a much more flexible and compact unit around this sensor as well as adding more of the functions people have come to expect.  I guess they have taken their own path with more modest investment and focused investment on image quality consequentially achieving less mass market appeal.  I am glad they did.  I certainly agree with you that if they could make this a more manageable size then it would increase its appeal.  The Sigma will not be my only camera, partly because of the portability issue.  I think I will take my DSLR and my compacts out depending on the trip.   If I find myself with a few minutes to spare, at an amazing view point, and I have carried my larger bag, it is then I think I will reach for the Sigma.

My 2 sense... the review is what it is and then some. I like that he rated how it performes taking various types of pictures.  I also can sense his joy when he waits in anticipation for the raw image to open up on his 4K monitor - who of us has not and continues to experience this unique thrill!

I find the Merrill and the original DP series to be far more user friendly in terms of operation, however from a post production perspective the Quattro seems to be a little bit easier to work with even in Sigma Photo Pro 6.X and Lightroom.

So overall friendliness is pretty much equal. As for IQ the Merrill is hands down the best camera and the DP3m is on another level. The only saving grace for the Quattro is the DPQ0 which obviously is unique and therefore this is the only Quattro that I own and I have the DP1, DP2m and DP3m.

Merry Merrill Xmas!

Thanks, very clear image.

I was pleased with the clarity on this one....struggling to replicate it though.

Maybe over processed but I found it a pleasing effect.  It was the golden sunshine hour, sunset, so the yellow is not as untrue as it might appear.  I was stunned that the bird is so clear.
