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.

Pros: File quality, FOVEON sensor, contrast and microcontrast, sharpness, amazing BW, robust and durable construction, ergonomics.

Cons: Those who choose a Sigma with FOVEON sensor do not see that the

Opinion: After the MERRILL, I tried this room: Excellent! It allows me to reach at least 200 shots compared to the Merrill, with better viewfinder and handle, returning to the touch a feeling of solidity and robustness. I find it reliable and perfect for those who want to take pure photography. I don't think it's for everyone, especially for those looking for a lightning-fast AF, but after seeing the images that he's capable of churning out this sensor, I challenge anyone to do without it!

Pros: RAW FILES!!!! The somewhat peculiar and very modern shape, the material of the body, the 30mm 1.4 sigma in kit but like all those of the art series, the comfort of interchangeable lenses and of course the FOVEON. If you have never tried this sensor do so, if you love photography try it, the sigma adapter that allows you to use SA lenses on sony mirrorless

Cons: The fact that the SA attack is an end in itself, given that Sima has developed the L attack with the Leica etc, the cost of the new high (relative, if you have a thousand euros to spend do it with your eyes closed to keep as a second body), some write EVF and screen and can also stay there because it is very painful, but you pass it over quietly. Definitely the choice of proprietary software at the expense of a serious collaboration with Adobe with Lightroom

Opinion: I was born in the era of the beginning of digital and my first car as a child was a coolpix in the early 2000s, but I also shot with my dad's films and reflexes. I found it by the way looking for more on Subito.it, I did two days of in-depth searches in the various blogs to see if it was worth the thought try and in the end I decided that the only way to understand its features was to buy it. Taken on Amazon because of the convenience of the return and I kept it a week. I also have an A7iii, before I had a D7100, I tried hyper bright fixed optics, poor and cheap zooms, both nikon and sony, but it was all so aseptic. Yes ok fantastic photos, incredible file workability etc etc, but the photo had no character, it didn't convey an emotion, it was just an image with a subject or a landscape inside. I was basically looking for the picture for a long time like foveon does without knowing the Foveon. That's why I tell you you have to buy it, you have to try it and try to look for the photos. It doesn't make 50-photo-per-second bursts, it doesn't have a viewfinder that finds a bird flying two kilometers away like Sony, it doesn't recognize your face in a quarter of a second like the Canon R5, but the question you really have to ask yourself is: do I need all this? Do you take only birdlife, formula 1, children running in parks and other situations where the AF of mirrorless obviously becomes essential? Don't you ever take a picture to treat her after years and relive the moment? After you take 30 pictures of the cat in 4 seconds what do you have left? This camera makes you understand the time, makes you think about the value of things thanks to only 200 battery shots, makes it clear that 50 photos are not needed (not on all occasions obviously) but 1-2 shots taken well and that transmit emotions. Balance of white from mediumformed, to iso 100 take photos that you did not think possible, INCREDIBLE colors, RAW files are a painting not a simple photo, all possible color yields, highlights and incredible material sensation and all this for "only" 1000€ including lens f/1.4. Of course it's not all gold this machine and the problems are varied: 9 focus points and an AF that could certainly be at least at the minimum acceptable levels like a nikon d7100 (and if you used it you know that we are talking about a very normal APSC of 4-500€), an attack that was not SA but one that can be used with a larger optical fleet, the program to process RAW that ONLY on an i9-9900k processor is fluid (and I write that processor because I have it) on a last type i5 forget to process photos, the price as I said but that is very personal, if it was at 700€ body with optics it would be to buy with your eyes closed. I made it only for the price that for my pockets, for a second body machine, is to be considered high for an object that does only a few things but does them excellently, I will certainly take a Sigma DP2 Quattro as a second body that costs much less although with a fixed optics and much more transportable having the same sensor and characteristics. CONCLUSIONS: Try it, you will love it. But remember, don't look on this iso machine over 200, it's like asking to rate a monkey for its swimming skills
