![]() | Sigma 135mm f/1.8 DG HSM Art Pros: Sharpness at the top, fast and accurate AF, pro construction, true optics Art Cons: Nothing Opinion: I've been testing this opt for two weeks and I've enjoyed all the optical and constructive qualities, I think it's the best 135 in the market, even the price is not exaggerated if we consider the quality of the product. I used it with the Nikon D750 and I did some beautiful portraits, fast and accurate AF even with moving subjects, perfectly sharp even af ??/ 1.8 with a gorgeous bokeh.

![]() | Nikon AF-S 24-70mm f/2.8 G ED Pros: Sharpness, AF, building, everything. Cons: Nothing Opinion: I have used this lens for many years with great satisfaction and under all conditions and I can only say that it is the only lens I regretted to have sold shortly before going to the VR version of Nikon always obviously. rn I can not yet evaluate the new 24-70 vr since I have it in a few days but I do not see all this difference.rnBut I can say that there are no other lenses of this quality with the same focus, I do not understand the previous review, I also made a serious comparison with the latest Sigma and the latter did not convince me even though it looks like a great product. sent on September 09, 2017 |
![]() | Nikon AF-S DX 16-80mm f/2.8-4 E ED VR Pros: All Cons: Maybe the price Opinion: I bought it about a year ago together with the D500, Perfect Coupled! Optics I think professional, great in almost all situations. In the past on dx I had the Sigma 17-50 f / 2.8 OS I'd preferred to Nikon 17-55 f / 2.8. This is superior in all, sharpness, VR, AF speed and blurry. I'm completely satisfied sent on August 17, 2017 |
![]() | Sigma 150-600mm f/5-6.3 DG OS HSM S Pros: Pro Construction, Great Sharpness at All Focuses, Great Stabilizer, Color Rendering and Very Good AF Cons: Minimum opening 6.3 and blurred Opinion: I had this fantastic Zoom in for a week and used it to photograph birdlife in my area, so far I've always used a fixed optic but the latter sometimes can detect a limit, while with zoom you have many more possibilities. RnI would like that price / quality ratio this Sigma lens is really exceptional. RnPaulightness if not superior in certain situations with much more expensive optics, it has compromises obviously, it's a bit dark (f / 6.3) and blurry is not up to Nikon pro optics, but for me I'm not a Professional should be the perfect lens. I was intent on purchasing it, also considering the pro, beautiful, robust construction and weatherproofness, but reading the previous review and going to search the web I found that "RobertoOK" is not the only one who has had The zoom jam problem. I heard two friends who have more than one of themA year, one of whom told me that she is always in mountain backpacks supported here and there, she has got rain and no problems. RnI will ...?

![]() | Sigma 24-70mm f/2.8 DG OS HSM Art Pros: Constructive quality, Sharpness, AF speed and precision, Contrast and color, Tropicalized Cons: I did not have time to find it Opinion: I ran a brief comparative test between Sigma 24-70 F2.8 Art and Nikon 24-70 F2.8 (Reflex Nikon D750): rnrnI Sigma 24-70 Art is a very well-constructed, good-sized lens and higher portability than Nikon , Such as sharpness, colors, contrast, we are on the same level. At 24 mm, 28 and 35 are slightly better than the Sigma, while 50 and 70 are better than the Nikon. RnrnFor the edge distortion the Nikon is somewhat worse than the Sigma at 24mm but is slightly better than 70mm.rnrn Blurry at f2.8 and I assume also other very open diaphragms in my opinion it is slightly for the benefit of Nikon.rnrnValue and precision Nikon's AF focus is also quieter. Rnrn The stabilizer obviously in some situations makes the difference (long times, say under 1/30), but there is something in the Sigma that does not convince me at the non-focal area, I try to explain, it would be to deepen: I used the Single-point focus, while the Nikon's closed-loop diaphragms (F8-F11) is clear and accurate across the entire frame, the Sigma besides the focus area is less sharp, it even looks like a micro-motion, and this is also noticeable with the most open diaphragms (F2.8), although in this case it is Less relevant. RnrnI would like the two lenses to be the same, while when I had the chance to try during a workshop the new Nikon 24-70 VR I noticed a big difference ... rnrn * Note that Nikon has been fine-tuning AF, Sigma No and since the D800 I found that many optics on many Mpx reflexes need fine calibration. sent on July 16, 2017 |
