Opinion: Dimensions and mass perfectly adapted to the eos 70 d, a quality construction in the line "Art", an incredible brightness, a very silky bokeh and a formidable sharpness : the Sigma Art 24 mm f / 1.4 (equivalent 38 mm mounted on the 70 d) is an optical that I had the pleasure to discover through various subjects, from the inevitable sunset on the ocean to the reportage, by way of the portrait in interior.
Contrary to what I feared, the lack of stabilization is not penalizing. In addition, the manual focus ring is nice and there was no need to make autofocus adjustments. In short : a very beautiful optics !

Opinion:Sharpness perceptible also too good and for this the contrast is too violent. I have had this view for at least three years and I abstained from writing a review first because I wanted the certainty of some of my impressions. From the first shots I was amazed by the sharpness really great, but... There was something that didn't convince me thoroughly. Let me explain: when you have been photographing for decades and you have made the habit of unexceptionable optics, you quickly understand if the one you are using is the right optics in everything. Sometimes, the beauty of a lens jumps to the eye already looking into the viewfinder of the reflex. Probably because the eye does not know anything about MTF but was developed with millions of years of ' research '. This does not happen with the Sigma 24mm f/1.4, which returns razor sharp images with a blur to F1, 4 that separates admirably the planes, and yet has always left me some doubts. Something was missing. Only recently I performed comparative tests with a very old Olympus 24 F2,8 on Nikon D850 and I saw what is missing: the contrast. The optics are razor sharp and are appreciated for this, unfortunately it is a perceived sharpness that constitutes only half of the image. Comparing it to the old lens you see how poor the Microcontrast is. I mean that the optics are engraved but the tonal variation of the colors, the micro shades, are much less rich compared to the optics of comparison, which at full aperture seems veiling but in detail returns, already all open, a greater richness of tones. From the comparison, it also highlights that the field framed by the Sigma is lesser, probably not really a 24 but more realistically a 25-26 (which is not a problem). The judgement is positive (a 9) but I think I'll change it for something more plastic.
Cons:Weight/size (but it is a compromise to accept for the final rendering of optics)
Opinion:I state that I use the version for Canon and I bought my new lens in the store. I had to calibrate to-3 in my case, the optics but then it always remained in focus even at full aperture. However, I will evaluate the purchase of the USB dock for various calibrations and update firmware. I tried the optics a bit in different situations and at various openings from 1.4 to closed diaphragms.. The sharpness and contrast it produces in the images is absurd.. Really I hit this lens and I'm really happy, I always wanted the Canon 24 1.4 L II But the price is prohibitive on the new and anyway it stays high even in the used market, I tried with the new Sigma 24 (found in super offer) and I'm really happy with it. Two negative things are the weight and the clutter that you make feel, but you know that the glass weighs and the cap of the lens that is obscene.. Replaced with an original canon and I would say it is definitely better. Would I buy it back? Absolutely! I will probably evaluate other Sigma Art to match the other lenses I own:
Cons:AF not perfect in some situations (need for calibration to be budgeted), made with artificial lights, starry "anonymous"
Opinion:Spectacular optics. I was looking for a fixed wide angle, sharp and bright to replace the Canon 24-105 L series that I had deeply disappointed. On the advice of a friend and curious to try a Sigma Art (of which I always read wonders and admired beautiful photos), I decided to throw myself on the 24 f1.4. Having both the 50l and the 135l I had initially rated the Canon 24l II. After a bit of various arrovellamentations I preferred to bet on the new Sigma compared to the Canon used since the tests found on the net the Sigma had less vignetting and I felt sharper at closed diaphragms, aspect that convinced me to throw myself on the sigma. Fearful of having problems with the AF I chose to buy it new on Amazon, so that I can replace it in case of any problems. Once mounted on my 6d are enough photos to leave me open-mouthed. This optics has an exceptional sharpness, much more than the 135l I possess. The blur is clear, without transitions and highlights the subject framed... provided to place it in the center where it is not the object of distortion and where the lens has the sharpest part. Shooting with a 24 F 1.4 was a real challenge for me..... you have to approach the subject but, composing with the subject at the center, where the distortions are reduced, you create a really amazing wow effect... I can say that some of the most beautiful photos I made I got my daughter with this lens. Recently I took a trip to Bosnia and Croatia where I took it as the only optics, satisfying myself in full and giving me some shots of which I am very satisfied. Coming to the cons I have to report that the rendition of Art is particular and coming from the Canon L series at the beginning I was puzzled. Specifically I found a flare rather pronounced when you frame a subject in backlight, positioning the sun in one of the four corners, which from origin to colored panes impossible to remove in PP, for the rest the optics seemed to me free from Flare on other less extreme occasions. Another defect I found is in the form of starry in the long night exposures in urban environments; The optics tends to keep the point lights even at closed diaphragms, presenting only a minimum hint of starry around the point light. Chapter AF: I state that I use it on Canon 6d and use the center point and then recompose using the AF-on button. As I said, not to risk I took it on Amazon, mine is almost perfect at all distances, I say almost because at full aperture, if I focus something at infinity, ends up to focus at random. Closing the diaphragm This problem does not occur. This problem is even more pronounced if you use slow times close to the safety time... it is not micro-moved, it is right out of focus. As soon as I can still I will calibrate it with the Sigma Dock. Even the 50l I did calibrate from Canon and after it went much better. Another thing I noticed is the yield in the white balance in the presence of artificial lights. This is a contrasting lens and with strong differences of light I happened that the photo was too contraed and difficult to recover in PP... Much better to exploit it with natural light where from the best of itself. I then make one last consideration on the SIGMA ART lenses: At the beginning even I was skeptical, I had pretty much just and always used Canon L series lenses... With these sigma I found a different rendition, very sharp and correct... I struggled to get used to it, then, Knowing the lens and familiarising myself with the same I figured out how to exploit it... and I really like it. It should be taken into account when evaluating the purchase. Would I buy it back? Sure. Once it happens it's a super lens!
Opinion:Optics to say the least fantastic, the mountains on the car and suddenly is love. Precious materials (metal and glass in such quantities that give a certain weight to the optics), top quality construction, impeccable assembly. The 24mm are the not too pushed wide angle that allows you not to have so much distortion, and in addition to landscapes, allows some portrait set. The large opening also allows astrophotography. At first I was oriented on the Sigma 20mm F 1.4, but then I evaluated that the 24mm in question would have been better for the possibility of mounting screw filters that I had already in the house. A real ART. Focus on the sides not always accurate but it is a defect to which I step over if I think of all the merits that this lens has. Recommended!
