Pros: Really good files, fantastic colors, simple and intuitive body, excellent ergonomics, unique possibility of being able to remove the infrared filter and make it become a full spectrum, excellent black and white

Cons: Too many, really too many! Exclusive to the photo pro program, which becomes frustrating due to its slowness and cumbersomeness! Vacuum cleaners on filter and sensor as if it were looking like a magnet, usable ISO up to 800, optics unobtainable on second-hand, and expensive on new

Opinion: I was curious to try this camera coming already from the SD 14, in the end I found it advantageous used and I took the whim, trying it I must say that in terms of operation it is quite slow but usable if compared to other more modern cameras but on the other hand those who shoot with sigma do a type of photography where the shot is studied well, The files are really satisfying in terms of colors and sharpness, the black and white once you remove the IR filter is exceptional! That said, once you leave you take several shots you start to see the cons or in summer it heats up a lot and you have to turn it off often, the battery does not last anything, the moment you go home to work on the files if you are not familiar with the sigma photo Pro program it becomes very frustrating, music led me to put it back on sale, too bad!

Pros: The Foveon sensor, Sigma lenses, an overall well-designed and ergonomic camera, Sigma adapters that allow you to use SA lenses on Sony mirrorless and L-Mount. Finally, an excellent Monochrome shooting function.

Cons: Poor battery life (remediable by having more batteries), really frustrating viewfinder.

Opinion: Those who use this camera are well aware that it is not a tool for 'universal' and everyday use; It should be considered as a second-use camera, but it still delivers amazing results today, despite the age of the design. I integrated everything into a system consisting of Sony and Leica cameras. My Sigma SA lenses (focal lengths from 14 mm to 105 mm) are used both on this camera and (using the appropriate adapters) on the other cameras; I therefore have only one series of Sigma SA lenses, without duplication with the lenses of the other cameras and taking advantage of all the automatisms on all cameras. For those who need to have the manual in Italian, I point out this link: https://drive.proton.me/urls/BQ9W0N3QZG#fjJyKr6afyVu

Pros: Sublime quality of files, sublime quality of camera design.

Cons: Operating speed, Af speed in low light conditions, held from 200 Iso upwards, battery life.

Opinion: The autonomy is not its strong point even if equipped with a 2000mh battery (it is known that mirrorless cameras are more thirsty for energy than SLRs) with a charge prepared to save on your SD card just a hundred shots. A lot of energy is absorbed by its particular FOVEON sensor. The autofocus is certainly not top-notch but not bad for those who shoot manually or do "reflective" photography certainly is not suitable for photographing F1 or sport in general nor, much less, birdlife. I, for my needs, rarely need an aggressive photographic focus but still remains inferior to all competing cameras. Despite being slow, the AF remains very precise and this is a compensation not to be underestimated. The image processor and the software take a few seconds to write the file on the SD, when I say a few seconds I mean from 4" to 8" and I kid you not, it depends on the size of the file we save, the number of photos taken consecutively and maybe some particular option activated by the menu. Unfortunately between lenses and flash, you can not find much in flea markets, the Sigma SA bayonet is part of a very rare elite. So for those who want to create a system on the Foveon must prepare to spend a lot of money, betting almost everything on the new. The Foveon sensor is extraordinary at a sensitivity of 100 Iso, we can push the camera up to 200, but from 400 Iso up the digital noise is very invasive, and can be compensated by an excellent black and white. We have 9 focus points selectable either individually or all together, with the single selection of focus points, we can select the sensitive size of the focus point, so as to cover a more precise or more "coarse" area. The machine has the recognition of the face of the AF, but attention is a help that not always its functions, often the machine does not notice the faces we are framing ... It must be said, however, that its yield is exceptional. Colors, contrasts, detail are very different from the digital to which we are accustomed. The raw file can be saved with Sigma proprietary RAW X3F, which is manageable only with the appropriate Sigma Photo Pro software, which is well done, free, and with professional functions but exhausting for its slowness (regardless of the computer you use). Saving in DNG is the alternative I prefer, I usually shoot with this choice, the files have about 130MB of information per photograph, and are well malleable in Lightroom or Photoshop. The sensor and its technology encapsulate the beauty for which this camera is worth using, its technology does not derive from an interpolation of RGB photodiodes with Fujifilm's classic Bayern or X-trans filter, but is a set of layers of the three primary colors. Just like the old films. This sensor is ideal if we want to allow light to pass through the three color filters to obtain unique and insatiable shades. The construction design of the machine is truly sublime. The body is tropicalized, robust, the function keys are as basic as they are perfect, they are all in place and after a few hours the feeling of ergonomics is already high. The SA lens mount has a detachable infrared filter inside, this is the only machine on the market that allows you to make this type of photography without drastic and expensive changes to the sensor.

Pros: Foveon sensor exceptional micro contrast, collects details that a Bayer has difficulty recording, black white worthy of a monochrome

Cons: Color usable up to 100 ISO, in B/W 800, otherwise it is below current average, AF, recording speed, lens available only Sigma, SAF bayonet out of production, old digital viewfinder, need to use SPP

Opinion: If it were not for the sensor it would be to be thrown away. But since it has the Foveon sensor it is the machine I use the most. Of course if one earns the loaf with this it is hard to make marriages. But to photograph is an absolute pleasure knowing the limits. The black white is really valid, you can do without editing IR photos.

Pros: The Foveon sensor, the proprietary Sigma optics, a certain simplicity of use, excellent RAW and JPG files, RAW development system in the machine simple and quick

Cons: Outdated support technology, embarrassing autofocus, excessive weight, ridiculous battery life, the Foveon will never - it seems - FF

Opinion: I arrived at digital after many years of film (sorry but analog you can not hear) and I started with a super technological Z6_II which I am very happy. I took the Sigma attracted by the Foveon and the vulgate according to which the files of this sensor are close to the film. Now in all honesty I must say that this machine churns out very beautiful files, at least in my opinion. To get the results I want I have to do much less PP than with the Nikon but even with this in the end I get where I want. The limitations of this machine are all in the technology around the sensor. An embarrassing autofocus for slowness and sometimes unable to act in low-contrast conditions (sea sky with a bit of haze the really impossible scenario), icing on the cake a battery with a ridiculous duration. It is a camera for contemplative photography, art, medieval old towns, gardens, landscapes, relaxed street. I hope that sooner or later Sigma Corp will deny me and pull out an FF with a technology around it that lives up to the current expectations.
