sigma sd quattro h — blog

While I love Sigma and their relentless pursuit of image fidelity and quality they slightly have shot themselves in the foot with their choice of mount on their new cameras. The cameras themselves are excellently built, rugged and capable studio and location shoot tools. Sigma capture pro is coming along nicely and allows for tethered .x3f and .dng shooting though I wish Sigma would allow for scaling the program for users with 4k screens. This brings me back to mount choice,the SA mount is very similar to Pentax K and has only a bayonet difference and it has the same registry distance as canon ef (44mm) . The problem lies in that only Sigma makes glass and while they have a rather fleshed out lineup I find myself wanting more specialized glass ie ultra fast apertures, trioplan style, more artist focused lenses. If they were to copy the Sony-FE mount or make something with a short flange distance the ability to adapt glass from various other mounts would make the system a whole hell of alot more viable to the average photographer. But there is one mount that is adaptable quiet easily M42. From m42 you adapt a few different style of lens like Pentacon and 6x6 lens. For the purpose of this review I used a Carl Zeiss Jena 180mm f2.8 lens paired with a unknown pentacon to m42 adaptor, then with a Kipon M42 to SA adaptor. The lens is obviously manual focus and with the focus peaking available by default with the Sdqh it is not terrible to use. I do recommend good lighting or the use of flash because the liveview of the sdqh becomes quite mushy and grainy without good light.

As you can see in tbe above photo the Carl Zeiss Jena 180mm really leans towards the green spectra in terms of color, it also has a high amount of chromatic aberration when paired with the foveon x3, but renders quite a bit sharper then what I was expecting from a very old lens.

Now the real question is, how's the bokeh? It's Tony the Tiger levels of great to be honest. Bokeh balls are round and soapy, compression is fantastic and dof is 3d-ish.

I'm truly happy with this lens particularly and with how it pairs onto the Sigma.

Down to some specs,

Aperture: f/ 2,8 - f/ 32

Weight (gr): 1350

Length (mm): 120

Filter Ø (mm.): 86

Aperture blades: 9

Min. focus distance (m.): 1.7

It has a super smooth focusing ring and very audible and noticeable clicks on the aperture ring.

Since the SDQH already isn't fantastic in low light even when paired with 1.4 primes it obviously is gonna need artificial lighting frequently to which I pair the Sigma ef-630 flash and the Godox Ad360 it has tons less abberations then when only paired with natural light.

As you can see in the above picture the way it renders is very 3D-ish with alot of compression and a very sharp fall-off it renders reds, greens and blues very beautiful but over saturates purples, but thats just my opinion. The bokeh... is friggin fantastic. Its very round and very soapy which I really like. It can be a tad busy on occasion but It's one of those things thats a matter of taste. Also remembering that the sdqh is utilizing a aps-h sensor (26.7 x 17.9mm) while the lense is made for 6x6 film which is 56 x 56mm so you are basically only using the center of already high quality lense which is normally the sharpest part of a lense.

So in all I think the journey of adapted lenes will be a beautiful path to travel down.

After a solid month of shooting with the Sigma Sd Quattro H which for the purpose of my sanity I will abbreviate to SDQH for this article, I can talk with with some useful knowledge about the pro's and con's of this camera.

Review-

Using this camera for mainly portraiture so I will review it as portrait camera, so far I haven't been able to use this camera for landscapes which I know it will succeed in that form as well. This camera has been used for two professional shoots, one during a quite rainy day which to be honest terrified me, but with the sealing on this camera and the 85mm Art it held up quite well. That leads me to the issue of durability and build quality.

The camera itself is build like a tank especially considering it is only $1200 hundred dollars at time of writing. The fit and finish is top notch, the camera is made from a magnesium alloy and covered in a leather-est type of plastic that has a very pleasing feel. The camera itself is surprisingly light considering it's size, but that pleasant fact is negated quite quickly by the length and weight of the Art Series of lenses by Sigma. The camera is also very well sealed against the elements in the form of a seal around the lens mount and sealed ports as well as the battery compartment which I have heard described as a submarine door, it is a twist lock and seal which has very quality feel to it. The buttons have very solid feel to them and in my opinion is that they won't wear out easily. The dials have very definite clicks and are very well implemented on the body and are easy to reach. As to whether the body is comfortable to hold I had my doubts if it would be comfortable but i was pleasantly surprised as it was very comfortable to hold and shoot even after a relatively long shoot.

The next thing i will address it the image quality of the SDQH, I'm not going to get into crazy specifics because I am trying to show the average person what the camera can do not specific bit quality or pixel size or the debate between foveon and bayer. To put it simply the SDQH is a megapixel monster of that is no doubt. You can zoom in well past 100% and still have remarkable detail, even under less then favorable light. The prints you can achieve with this camera are basically on par with the Pentax 645z for detail but the 3-d effect you achieve with a larger then 35mm format sensor isn't here though sadly. But for 5 thousand dollars and some change less can you really complain? I can't and won't. For the portrait sessions I have used this camera on I really haven't wanted to put it away and use my other cameras. It is good, and the files are scary sharp. If you shoot in mostly jpegs like I do ( I know I'm a fool don't have to tell me ) the bnw files come out to be around 20-25 mb's and the color files can run 25-35 mb. If you choose to shoot in .dng or .x3f the files are ridiculous. The ones i have seen have been in the 100 mb range and more. A simple snap of a scotch bottle in my room was a 141 mb .dng and that was not a well lit photo that would push the dynamic range of the file. Here are a few websized images from a few shoots I have done with the SDQH.

As you can see the camera makes awesomely sharp files and the bokeh from the Art series of lenses is quite pleasing to my eyes, it may not be to some bokeh-philes but for my purposes and to the average consumers it is quite fantastic. Now this brings me to the purpose of bringing up the lenses. They are central to this camera as are any lenses to any format or ecosystem of cameras, but for Sigma they are something special something a little bit above. The lens wasn't built to compliment the body, the body was built to compliment the lens. The lens are fantastically sharp and manage to create very pleasing images in terms of color reproduction and bokeh.

Cons-

I promised to always be fair and unbiased in my reviews and as much to pains me to do this to a camera I love... I have to be true to you my reader. The auto-focus is accurate, but slow, and when I say slow I mean you can fall in love with your model, start a relationship, start a family and watch the grand kids play in the front yard before this thing focuses. That is my biggest complaint with the system, the high iso performance isn't great but that's expected with a foveon system because of the sensor architecture. The foveon is built in three layers of color instead of a mosaic patterned sensor. This means the light and color is more accurately reproduced but at the loss of low light performance. That was a trade off I was willing to make. That's also a choice you have to make if you want to experience foveon magic. Also a word to the wise have fun learning the off camera flash game with this camera. It has made me a better man that's all I will say.

Conclusion and Final Opinion-

The Camera is a MegaPixel monster as well as a hot mess, but that's ok with me. I like to think I am a fairly technical photographer and I like to shoot and re-shoot till I have a image I'm happy with and the SDQH is really great if you want a camera that challenges you but creates a fantastic image if you're patient. The system isn't a upcoming system as foveon and Sigma have been producing camera's since 2002, you would hope that they would have more complete ecosystem and it is fairly deep in regards to lenses and flashes, but I wish they would make off camera flash more universal so that wireless HSS and TTL were available. But all in all I really enjoyed the camera and its quite fun to pixel peep, if you're into that kind of thing. But then again who isn't. Overall rating 9/10.
