Opinion:On Sigma FP it's not my ideal lens, it's still an amazing optics, excellent quality across the entire frame, cinematic and progressive blur. Sold to buy the 20mm f2 (already widely recommended on other reviews) which I use with the crop of the sensor at 30mm. For lovers of the category it remains a must have. Rated 9.
Pros:Quality of materials and construction, compactness, diaphragm ring, moderate diameter filter connection, metal hood
Cons:No block on the diaphragm ring. When it is necessary to remove or engage it, given the compactness it takes a little attention to put the fingers to grasp it in the "right" points (but it is not a defect, but a feature)
Opinion:Of this series I bought the focal lengths 24, 35 and 65mm. A generalized evaluation can be made for all three as the performances are superimposable: excellent quality from edge to edge of the frame, absence of chromatic aberrations, flares almost absent (but I did not stress them thoroughly), slight vignetting at full aperture, visible distortion (variable, depending on the focal length). These last two features, however, are not even noticeable by enabling the lens profile of the photo editing software used. Even looking at the image just taken on the display of the machine you do not notice, as you will see the jpg, which is already correct. It lacks stabilization, but having it already on the sensor of my camera body, I can shoot in peace even at low times. I think these are perfect optics for the current mirrorless bodies that are small. The whole is always slender, manageable, not very heavy and not at all showy. I had also paid attention to the "Art" series before their purchase..... But I made this choice not for an economic reason, but for a very important practical feedback: weights! For those who move a lot with the backpack on their shoulders it is not easy to manage 3 or more "important" optics on the shoulders. Then I also saw that, for the type of photography I do the aperture 1.4 I do not need, and f2.0 is more than fine ... The 35mm was the first lens I bought in this series: Love at first sight! After trying it I also had the confirmation of having made a very good choice
Opinion:Love at the first shot. I use it on the Sony A7 IV and the files it churns out are great from the point of view of sharpness and colors. The fact of being able to decide whether to use the diaphragm ring on the lens or on A through the ring on the machine I find a not indifferent plus. To the touch this lens returns all the quality with which it was built. Excellent bokeh at full aperture
Opinion:Well done, solid lens, smooth and precise rings. Being able to manage the diaphragms with a ring is an exceptional plus, very precise and pleasant to the touch. The AF doesn't miss a beat, very high image quality. The button for manual focus is very useful. Paired with the Sony A7C it churns out very nice files and maintains a compactness and pocket weight.
Opinion:Well-constructed lens, with fluid and precise rings. Metal lampshed like the lens body, now a rarity from prestige optics. Used on Sony A7III it is well balanced. Good sharpness and blurry, which become excellent from 2.8 to 5.6 where it give its best. Cold sigma style colors with three-dimensional images despite minimal aperture. Price still high for an f2. Not detected flare even with sun in the center of the lens. The only major flaw is excessive distortion. It corrects itself in posts, but it's a break because you have to update the software, which is often a paid operation. The magnetic cap is cool, but impractical when the lampshade is inserted. I recommend it for those who want to stay light and enjoy all the advantages of today's mirrorless.
Opinion:I would like to start by pointing out that my judgment relates to the optics mounted on the A7RIV. Excellent resolution across the field since f/2.0. It reaches a maximum of 4.0 onwards and then drops by diffraction from 11.0. I put first the defects that consist of a fairly high drop in light and distortion that, however, are perfectly compensated by software as is now the case on almost all modern optics. Let's get to the pros by starting by saying that I haven't seen chromatic aberration and that the uniformity of yield in the field is really excellent. What strikes most, beyond the extreme sharpness, are the quality of the blurry and pleasantness of the same on the different floors. It reminds me a lot of another member of the Sigma DN family, 45 2.8 and while not reaching the same creaminess comes very close to him. Compared to 45mm it also loses that characteristic less sharpness at close distances due to the undercorrect of spherical aberration. Here even at reduced distances the sharpness is excellent and much of the "paste" that characterizes this optics is preserved. Mechanically it's a gem. Entirely made of metal, soft and very precise MAF ring as well as that of diaphragms. Metal cap for me useless but it is included in the package. VERY fast and precise MAF in both AFS and AFC. The price is a gem. Considering I come from Sigma DN 1.2 I can make a comparison. Of course we start from f/2.0 and I can say that as far as I am concerned the performance is overlapping. We obviously lose a diaphragm and a half of maximum brightness but we gain in weight and size and, as mentioned, less than half the price. I mean, I give a 10- and I think it's fully deserved. (the less I put it because, for psychological reasons only, I would have preferred a better non-software correction of light loss and distortion). In the gallery you can find some shots. No posts and 50% of the quality loaded for space reasons.
Opinion:Lens absolutely devoid of character or poetry. It's too perfect. Sharpening all over the field already at f2.0, creamy bokeh, excellent backlight hold, no field curvature, excellent microcontrasto and colors, fast and reliable AF, AC under control. Excellent construction: at the first specimen tried no tilt or decentralization, I believe that Sigma can be trusted for the quality of production.

Opinion:great sigma!! exceptional objective.. fun and perfectly the line with the idea of compact and portable mirrorless.. all the quality of sigma with the addition of the lightness that was lacking with their goals.. impeccable construction, quick and precise AF on the eyes, also tested on animals, I think that soon I will also buy the 65mm
Pros:Compact - Excellent Construction - Diaphragm Ring
Cons:It's not very clear at all.
Opinion:Mounted on the A7iii is really fun to use and take out. The blurry is very pleasant, the construction is impeccable and the focus is lightning fast, the focus on the eyes is also excellent. At TA maybe it leaves something in sharpness that still comes out excellently already at 2.8 The diaphragm ring is really comfortable, too bad you can not take the click off.
