2/25/2024 0 Comments Sigma 24 70 2.8 ex dgMany of the images on my Flickr and Blog were taken with this glass. NOTE: I had mine calibrated when I discovered it was out of tolerance to my crop body. It's passable but if sharpness is critical, you have to stop down or use something else. It's much better than the average kit lens, but if wide open performance is important, look elsewhere. The lens had minor scuffs but the camera had to be sent in for repair. I'm not complaining though.I was hiking on Baffin Island and dropped it and my 1D when I lost my footing. The build is rugged and you pay for it in the weight. It's never failed at the only reason to own it - it's wide focal range. My copy has been to several countries in all kinds of conditions from snow, rain to hot. ![]() It's also a good piece of glass to have in your gear bag when travelling. The fun continues even for hi-iso applications when stopped down. At small apertures from f/8 down to f/11 this thing rocks. It's a perfect lens for studio work which I do. The images are very close to Canon's 24-70 glass with slightly muted colors and contrast as compared to the Canon. I would say the optimal sharpness is reached somewhere around f/5.6 or so.Īside from that I've found this lens extremely useful. My 50 1.4 is much sharper from f/2 onwards. My 70-200 F4L is sharp wide open from corner to corner. You don t realize the softness until you actually use a sharp lens by comparison. It get's much sharper on the wide end, even at f/2.8 but even better from f/3.5 onwards. ![]() ![]() I've used this lens for over a year now and it's certainly true what is generally said about it soft wide open at 70mm and f/2.8. Slightly soft wide open, extends to go to wide angle, loud AF Here you can see some samples about its image quality: If you have a nikon and want to have a lens that suit FX and DX sensor and you want to save some cash this is the lens for you. The zoom ring is not smooth in all range, maybe because the front element is heavy. The bottom of line is, it is a very good lens for the price charged and the performance to shoot landscapes or portraits with the correct exposure, aperture and with the right ammount of light, do a high quality sharp image. In other hand, noise in dark area is better than the 18-105mm, because somehow does not show purple dots, only black ones. I found this problem in every aperture range. I can tell that because the 18-105 kit lens, in same scenario, perform 200% better, and even with the noise, the image is focused in dark area, not blurry or out of focus. I know you are thinking "that´s is normal, it is the dark problem", but it is not. In this case, the darken area of the image have a very poor quality and it is not sharp. When you shoot, the darken part of the image get blurry, like a out of focus blurry noisy image. I am disapointed by lens performance at night. To be honest it produce less noise than my nikkor 50mm 1.8D. AF works great and it is not as noisy like people complain. ![]() This is the kind of lens that dont give work to you on the post processing. It produces a warmer tone than 18-105mm lens, I love it, and 90% of shots I do only need to apply lens profile, because image is very well balanced (colors and the exposure) already. I can tell also, in this scenario, it perform better than D90 18-105mm lens kit. So, if you are shooting landscape, or buildings at wide open, I can tell you, with the correct exposure, you have a very high picture quality. I found some distortion CA and purple fringe wich is 100% correctable (at least with the lens profile in Lightroom 3). Center shows a very high quality image and borders are a little soft. Its a little soft at wide open and you need to step down a little bit. People get intimidated by that lens, its nice!Ībout IQ I can tell you I like when used at day, despite being a f 2.8. Well, first of all is a big, heavy and bulky leans and it uses a big filter. No front or back focus.Įnglish is not my mother language, I will try to be "understandable" Smile. The lens is 3 years old and it is perfect, no problems due age, except to the rubber focus ring that is a little "dry". I bought a used copy of this piece to use in my nikon D90.
