The following opinions have been automatically translated with Microsoft Translator. | Xiaomi 14 Ultra Pros: TECHNICAL REVIEW WITH MTF, it is unusual to find technical feedback with MTF for smartphones, so I point out this one that uses the same criteria as any lens, resolution parameters, vignetting, color rendering, Cons: Read the review and everyone draws the consequences, it's an interesting review Opinion: It is not easy to find reviews on the goodness of the photographic sector: here is a serious review: https://www.fotografidigitali.it/articoli/6796/xiaomi-14-e-xiaomi-14-ultra-sono-davvero-macchine-fotografiche-5g_index.htmlLeggete the review and everyone draws the consequences, it is an interesting review If you look in the magazine they also make the comparison with the Sony RX100 where the 23 mm of the Xiaomi is positioned very close for MTF With these 4 physical lenses, the Xiaomi 14 Ultra offers 6 focal lengths between 12 and 240mm equivalent. Considering, again, the 23mm as "1x", we have, in order: 0.5x, 1x, 2x, 3.2x, 5x and 10x. It is possible to shoot at full resolution at 50 Mpixel with the main lenses 0.5x, 1x, 3.2x and 5x. sent on July 28, 2024 |
 | Sigma 24-105mm f/4 DG OS HSM Art Pros: Much better than it looks Cons: It is not tropicalized and eats the extreme edges at 24 mm Opinion: What do you want it to be is the usual 24-105 ! No wrong, it's a Mr. 24-105 that at F4 you have a scary 24-40 mm as center and median sharpness, and so if you go to do street or reportage it's BINGO. You want to do landscape: it has a 28-70mm flat, edge-to-edge at f8. With the portrait you have an excellent 80 and a 105 that put to the whips could seem weak, but in reality with the conscious use of software such as PhotoAi2 you recover the finest details, to be clear at 24 mpx you don't see the difference with the tamron 70-200g2 at 100 mm. So yes it's not like a fixed, but in real use the differences are just minimal. THE FIRE?? It's there, and if it's not there, now with Photoshop Camera Raw you can go from F4 to F2 in a flash. You don't have the blur of a 50 1.4 or an 85 1.4, but then bring a fixed one for special occasions. In summary, you take 80% of the photos in a trip, for the rest you bring a fixed to the focal length you like. Yes but F4 is dark I have to raise the iso!! Now with Dxophotolab you develop the 20000 iso in an exceptional way and in any case it is stabilized and shooting at 1/10 is feasible. Rated 9 deserved. Used on Nikon D850 D800. precise. No problem with Front Back focus. sent on March 10, 2024 |
 | Tokina Opera 16-28mm f/2.8 FF Pros: Quality at the right price Cons: Weatherproof, even if it has the rubber on the attachment. Opinion: After a few months of use and testing, I can confirm that it is a very usable lens. From the tests on targets it is clear that it suffers from a slight curvature of the field and that the DOF (depth of field) with dense sensors is actually very sensitive to small displacements of the machine, differences of 2-3 cm are noted in fine details, the DOF at 18 mm f2.8 at 2 meters theoretically should be 3 meters instead just a difference of 2-3 cm between right and left and you immediately notice the Edges. In astro-photography certainly at f4 makes very well, however, despite being a wide angle pushed the difference between shooting on a tripod and freehand even at times of 1/100 is noticeable. Flare resistance is good. It has an affordable cost and does its job very well. One of the few reviews with graphs can be found here: https://www.digitalcameraworld.com/reviews/tokina-opera-16-28mm-f28-ff: for landscape designers F 16 holds up very well, to make portraits set 18-28 mm F2.8 is fine. For astro advice 16 mm F4. to give an idea of the central sharpness in line w / p height at F 2.8 goes from 2100 to 16mm to 1300 to 28 mm. (For comparisons 50 sigma to 1.4 is 2100, the tamron 90 macro is 1900 f 2.8, the sigma 105 macro is 1500 f 2.8): so do not worry is a very flexible and usable lens. sent on December 28, 2022 |
 | Nikon AF-S 50mm f/1.8 G Pros: Light, featherweight but also effective at TA. Very appreciable in APSC for portraits. Cheap but Great Cons: Barrel, distortion makes it less suitable than 50 Sigma Art type for narrow portraits inside Opinion: I also add my praise to this little miracle. Great at f 1.8 for portraits on APSC, Su FF prefers to use sigma 50 1.4 art for greater yield and neutrality in distortion. If you think about taking a walk carrying a wide angle (es Samyang 14 mm) and this joy you can do great things with a derisory weight. To have sent on March 24, 2021 |
 | Sigma 50mm f/1.4 DG HSM Art Pros: so much quality at the right price Cons: for now not found, weight is not a problem for conscious use. Opinion: I compare the nikon 50 1.8 G, excellent lens, but the sigma 50 1.4 differs mainly in the absence of distortion, it is as if it were a 60 mm for narrow portraits. It has less nasone effect. You buy it to use it at 1.4 although in full-length portraits the edges lose too much to 1.4, but recover very well at 1.8 even at the edges. It is the right lens to use for interior portraits with little light and limited space. If on a trip I had to use only one lens I would take away this. For autofocus, for now I have calibrated in the car at 1.5 meters and it seems to me that it is fine even at greater distances without performing the fine calibration with the dedicated dock sent on March 19, 2021 |
 | Samyang 14mm f/2.8 IF ED UMC Aspherical Pros: Yield in the landscape, value for money Cons: Unusable distortion in architecture, but well correctable in post and in sticking Opinion: I just want to highlight how the distortion, which sometimes is also nice, is excellently corrected using the sticking of 2-3 shots. In fact also applying the corrective profiles the images appear very distorted at the edges with a sort of central crush and an exaltation of the height at the sides. The procedure I performed is to open the raw in Dxophoto lab that corrects the geometry, then converted to TIFF do the sticking with the Windows Image Composite Editor (which is free), which I think does a great job and maybe better than Photoshop. In this way you will have much more natural images. It may be that it is necessary to first combine the shots to groups of two in order to facilitate the overlap. My specimen is equipped with electronic recognition and is perhaps lucky, but with the d800 you get considerable details even at the edges to F8, sent on July 31, 2018 |
 | Tamron SP 70-300mm f/4-5.6 Di VC USD Pros: Value for money Light. Most sharpness sufficed. Very efficient stabilization. Cons: For 300 euros I do not have the courage to find Opinion: Premise the yield is better and not little with the FF and especially with the Mega Mpx (used on the D800 has a whole other yield than the d3200): from 70 to 135 mm from the best of SE and therefore to F5 to 135 mm allows you to make good portraits with a Nice blurry. Even at 300 mm f. 56 You get some nice portraits. It's a good travel companion and photo reportage. And it goes very well to make some landscapes in stacking. So I would call it a good compromise. Now there are 100-400 both Tamron and Sigma, but they cost twice as well. Often you get distracted in technicalities from the real goal: think and take pictures. And often I also have to soften the portraits because they are too sharp. So only advice taken thinking. If the subject is good it is both at F5 and at f 2.8. Who complains that it is dark or is dumb or is of competition: when you buy it you already know it can give you. On the sharpness speech remember that under the 1/200 the micromove from the mirror increases and not little. That's why the FF among other things is favored: then use the LV to make good use of the stabilization. sent on May 26, 2018 |
 | Sigma 105mm f/2.8 Macro DG OS HSM Pros: Incredible versatility: from portraits, to still life, to macro, with a blurry fairy tale all at a low price Cons: Perhaps the stabilizer is not up to the most recent. but you shoot well at 1/60 Opinion: It is probably the most versatile fixed lens, with an excellent optical quality and really embarrassing in the portraits made with the maxi pixels at 36-50 Mp, where it allows the contrary of some fixed fixtures to approach to perform some details. The out of focus at 2.8 is piacevolernrnSulle macro quality just look at the photos, you can range from microscopic details with extension tubes, to magical effects similar to vintage lenses.

 | Nikon D800 Pros: Value for money at the time unbeatable, given the prices of used: my combination with the sigma 105 holds very well the shake: at 1/200 the files are almost equal to those taken with the live view. So for some reason the combination with the Sigma is almost perfect to reduce the vibrations of the mirror. Cons: dry snap: but I have the impression that they have improved the vibrations during production compared to the first releases, limited in the videos Opinion: Purchased used at 1000 euros with 8000 shots. perfect, not a scratch. I've been using it for a few months. I state that I come from a d3200 and then I can only say what struck me beyond the obvious: perfect automatic white balance, very natural colors without any post, (directly converted into PS ACR, otherwise the nikon converter alters the gamma tones and colors in my opinion). The 36 MPs are those that it takes to exploit well the good optics that already there are without fainting in the super ones, that for very little more there is a chasm of cost. Therefore good detail even with non-high-gloss lenses (eg nikon 50 1.8G) which allows important recoveries and emergency cutouts. Good workability of files that weigh 40 MB compressed without loss. The battery is limited but still arrive at about 600 shots. The discourse of shake is very related to the mirror in all SLR already starting from 1/500 and worsens more and more to longer times. Therefore if you want to have the maximum sharpness you have to shoot in live streetswo in delayed shooting. The micromosso sincerely I saw better than the d3200 perhaps for the weight that greatly attenuates the vibrations and perhaps due to the lower density of the sensor. Among other things, keeping the ISO well is easy to stay within tight security times. The burst limited to 4fps, for me it is not a limit because I do not do sports photos or birdlife. As for the notes on the AF, I honestly did not see them on my sample. rnrnIL video segment I have not evaluated, but certainly is not up to the times. But I did not take it for this. rnrnIn definitive good for portrait, landscape and macro. Excellent for newbies who want to experience quality. sent on December 08, 2017 |
 | Nikon AF-S DX 18-55mm f/3.5-5.6 G VR II Pros: from 18 mm to 27 mm f 5.6 is very sharp, excellent handyman, good stabilization, economical: coupled with light bodies seems to have a compact. Cons: Technically at 55 mm f 5.6-8 imatest da for Excellent Yet the color is less vivid than the 50 mm 1.8 G. Coupled with light bodies should be used in live view at times greater than 1/200. Update: At 55 F 5.6 My obviously suffers from back focus Opinion: It is rightly a lens from kit, but you can really use at excellent levels of sharpness between 18 and 35 mm, exceeds the excellence by closing to F 5.6 -8: So you can experience the portrait, even at 24 mm (which corresponds to the 35mm in FF) that is of great fashion , with the limit of the diaphragm to F 4 but that allows you to shoot at 1/30 to 1000 ISO almost in the dark (1000 ISO are handled very well also by a d3200 in Dxophotolab). Very important: for sharpness at times greater than 1/200 you have to shoot in live view for the moved by Mirror. Another point in favor in addition to stabilization (you can take pictures at 1/10) There is the possibility of approaching about 20 cm becoming a semi-macro. In summary with a modest expense allows you to have a lot of fun. For review look at https://www.ephotozine.com/article/nikon-af-s-dx-nikkor-18-55mm-f-3-5-5-6g-vr-ii-lens-review-24155. Excellent travel optics. Personally I associate it often to the D800 with fixed and zoom 70-300 for the street. Often snubled, it is excellent in the street where the classic diaphragm is a 5.6-8. So before criticizing it you have to learn to exploit the characteristics that among other things also allow creative moving in safety at 1/10-1/30. Another thing to know is that with Dxophotolab you improve the SNR ratio of 4 DB Therefore the use of the aperture 3.5-5.6 at 1000-2000 ISO is now much more feasible even with non-modern bodies. So before you think about spending on other goals, learn how to use it well. To be associated, if necessary, for portraits at a 50 mm f 1.8 and a wide angle type Samyang 14 corresponding to a 21 mm in FF. Update: My specimen mounted on d3200 suffers strangely of backfocus. Fortunately, using it from 18 to 35 mm is not so dramatic. sent on May 04, 2017 |
 | Nikon D3200 Pros: Cost/Quality ratio: for 300 euro with objective 18-55, difficult to ask more: so much yield at a negligible cost Cons: In shots below 1/200 you should shoot in live view. The blur that causes the mirror is too obvious. Lack of fire micro-adjustment Opinion: With good lighting The 24 MP's are all exploited. And it's a show. Very manageable and compact with the retractable 18-55. A note on sharpness: If you measure on MTF test cards, you realize that shooting with and without a tripod in Live View, there is an abyss. So it's pointless to think of using super sharp lenses if you take photos on the fly. Compared to the d7200 it definitely goes corrected the sharp of a few tenth. On seal to ISO: Dxomark the DA good up to 1130 ISO measured, which correspond to 1600 of room. Big difference lies in the development of the RAW: definitely recommend Photoshop compared to NX-view especially for incarnate and yield gradients. If you develop in Dxophoto lab you get good photos even at 3200 ISO excellent for portraits, landscapes, macros. Less suitable for use with driven telephoto lenses (500-600 mm) for limited high ISO hold (but shooting at F 8 to 1/1000 at 800-1600 ISO in good light conditions is not that difficult. A function that is lacking and that could be useful is the HDR and of course the autofocus microcalibration. If you use it with good lenses eg 50 1.8 G you will make beautiful portraits all in a featherweight. If you want the sharpness in the landscapes: try 18-55 to 18 F 8 on Tripod LV and you will be amazed by what you can give this machine if you then use Samyang 14 F 8: You'll love, a lot of yield at a negligible cost learn to use the technique well and Post and see yourself what you will get from these good photo machines sent on October 14, 2016 |
